What is the average utility bill for someone living alone? We explain the estimated costs of water, electricity, and gas, and how to save money.

What are the utility costs for someone living alone?

When you start living alone, one of the things that concerns you, along with rent and food expenses, is utilities. Monthly expenses such as electricity, gas, and water vary greatly depending on your lifestyle, but knowing the general guidelines can be helpful when managing your household budget and choosing a place to live.

First, let's look at what "utility expenses" specifically refer to, and then we'll explain the average utility expenses for a single-person household.

What is included in utility bills?

"Utility costs" refer to the following three expenses, which are essential infrastructure costs for daily life.

• Electricity bill: Costs incurred for using lighting, home appliances, air conditioners, etc.
• Gas bill: This is the cost mainly used for cooking and hot water (city gas or propane gas).
• Water bill: Expenses necessary for all aspects of daily life, including drinking water, laundry, toilets, and baths.

These charges are billed monthly or every two months, depending on your region and contract. For those living alone, usage can vary significantly, so it's important to know the estimated costs.

Average amount for single-person households (based on Ministry of Internal Affairs and Communications statistics + latest trends)

According to the Ministry of Internal Affairs and Communications' "Household Expenditure Survey (Single-Person Households)," the average monthly utility costs as of 2024 are as follows (national average, single people aged 20-40):

• Electricity bill: 5,500 yen
• Gas bill: 3,000 yen (if using city gas)
• Water bill: 2,000 yen (approximately 4,000 yen for two months)
• Total: Approximately 10,500 to 12,000 yen

However, this is merely an average and can vary depending on the region, season, and lifestyle. In particular, during the summer and winter when air conditioners are used frequently, and in areas with propane gas, it is not uncommon for gas bills to be nearly double the average.

Average electricity bills and tips for saving money

Electricity bills represent a significant portion of utility expenses for single-person households and directly impact the overall budget. The amount you pay each month will vary depending on your daily usage, especially for frequently used appliances like air conditioners, refrigerators, and microwaves.

This chapter explains the average cost of electricity and ways to save money on it.

Average monthly electricity bill and annual fluctuations for single-person households

According to the Ministry of Internal Affairs and Communications' household expenditure survey, the average monthly electricity bill for a single-person household is approximately 5,000 to 6,000 yen. However, this is an annual average, and the actual amount fluctuates significantly depending on the season.

For example, in the summer, the cost increases to around 6,000 to 8,000 yen due to frequent use of air conditioning, and in the winter, it can rise to around 6,500 to 9,000 yen due to the use of heating appliances and electric blankets. Conversely, in seasons like spring and autumn, when heating and cooling are hardly used, the cost is often kept down to around 3,500 to 5,000 yen.

As electricity costs are greatly influenced by lifestyle and climate, it's important to be mindful of controlling your usage within reasonable limits.

Relationship between contracted amperage and energy savings

Depending on your contract with your electricity company, your monthly basic charge may be excessive. One area you should particularly review is your "contracted amperage." While a higher amperage allows you to use more electricity simultaneously, it also increases your basic charge.

For those living alone, 20 to 30 amps is often sufficient, and anything over 40 amps may be excessive. If you haven't reviewed your contract since it was signed, you might be able to reduce your monthly fixed costs by changing to the minimum amperage necessary based on your electricity usage.

If your circuit breaker trips frequently, it's a sign that you don't have enough amperage. However, if you're able to live without any problems, it's worth lowering the amperage.

Precautions when using air conditioners in summer and winter

Heating and cooling consume a significant amount of electricity, so paying attention to how you use them can lead to substantial savings. The following tips are effective:

• Set the air conditioning to 28 degrees Celsius and the heating to 20 degrees Celsius as a guideline.
• Use a fan or air circulator to circulate the air.
• Close the curtains to reduce the impact of the outside temperature.
• Determine whether it's cheaper to turn off the air conditioner when going out or to leave it on.
• Clean your air conditioner filter regularly.

Furthermore, older air conditioners are energy-inefficient and tend to waste electricity with prolonged use. Even if replacing it immediately is not feasible, simply being mindful of the temperature setting and usage time can save you several hundred to a thousand yen per month.

Average gas bills and differences in pricing structures

Gas is an essential part of daily life, used for cooking, hot water, heating, and other utilities. For those living alone, monthly gas bills vary greatly depending on usage, but one thing to pay particular attention to is the "type of gas." City gas and propane gas have different pricing structures, and even with the same usage, the amount paid can differ significantly.

Differences and effects between city gas and propane gas

In Japan, two main types of gas are used.

• City gas: Supplied through underground pipelines in urban areas. Prices are stable and the unit price is relatively low.
• Propane gas (LP gas): Gas cylinders are delivered to each household for use. Both the basic charge and the unit price are relatively high, and there are significant regional differences.

Many apartments for single occupants and properties in the suburbs use propane gas, which can cost more than twice as much as city gas. Even if you use the same amount of gas per month, a bill of 3,000 yen for city gas might be 5,000 to 6,000 yen for propane.

When choosing a property, be sure to check if the type of gas used is listed.

Reasons for high gas bills and how to review them

The main reasons for high gas bills are as follows:

• This is a propane gas contract.
• Frequent use of hot water (reheating the bathwater or taking long baths)
• Using gas heating in winter
• The water temperature setting is too high.

The following methods are effective for reviewing the system:

• Shorten shower time
• Reduce the number of times you reheat the bathwater.
• Check your gas company bill and consult with your property management company if the unit price is high.
• Lower the temperature setting on your gas water heater slightly (around 42°C is a good guideline).

In the case of propane gas, the unit price may be lower through negotiation depending on the supplier. Inquiring through your landlord or real estate company is one option.

Costs vary depending on how you use your bath.

For those living alone, whether you take a bath or just a shower can make a difference in your monthly gas bill.

• Filling the bathtub: Since approximately 150 liters of hot water are used at a time, the gas cost per use is about 100 to 150 yen.
• Shower only: If you keep each shower to about 10 minutes, it will cost around 30-50 yen per shower.

Lifestyle habits such as "taking a bath every day" or "using the shower for extended periods" can increase your gas bill. In the summer, you can save money without much effort by taking only showers or slightly lowering the water temperature.

Average water bills and water-saving tips

Water bills are generally considered to be relatively small compared to other utility costs, but they can vary surprisingly depending on daily usage. In particular, if you frequently use the shower or washing machine, the bill can be much higher than you expect.

This chapter explains the average water bill for someone living alone and some easy-to-implement water-saving tips.

Estimated monthly fee and billing timing

The average monthly water bill for a single person living alone is around 2,000 yen nationwide. However, in many municipalities, water charges are billed every two months, and the amount billed each time can sometimes be around 4,000 yen.

This amount includes the basic charges for water and sewage, as well as usage-based charges. Many areas use a "tiered pricing" system where the unit price increases the more you use, so it's important to be careful not to overuse water.

Water rates vary by region; some municipalities, like Tokyo, have relatively low water rates, while others, such as regional cities, tend to have higher rates. When choosing a place to move to, it's a good idea to check the estimated water rates.

Water-saving methods for toilets, showers, and laundry.

Even when living alone, small daily efforts can be effective in saving on water bills. The following points, in particular, are easy to be mindful of and easy to incorporate into your daily routine.

【toilet】

• Choose a property that has a water-saving toilet installed.
• Simply switching the lever from "large" to "small" can cut water usage in half.

【shower】

• Leaving the shower running for 10 minutes uses approximately 100 liters of water, so reducing the usage time by just 5 minutes can significantly save water.
• Make it a habit to frequently turn off the water while brushing your teeth or shampooing your hair.

【laundry】

• Washing laundry in batches can reduce water usage.
• Make use of "Quick Mode" and "Water Saving Mode".
• If possible, using a front-loading washing machine will use less water than a top-loading one.

Another option is to replace old faucets and showerheads with water-saving types. An investment of a few thousand yen can lead to savings of several thousand yen or more per year.

How much difference is there depending on the season, region, and gender?

Looking only at average figures for utility costs for someone living alone doesn't give a clear picture of the reality. In reality, monthly expenses vary greatly depending on the season, region, gender, and lifestyle. This chapter explains how utility costs fluctuate, broken down by the main factors.

Differences in utility costs between summer and winter

Seasonal fluctuations are one of the biggest factors in overall utility costs. In particular, electricity and gas bills increase in summer and winter due to increased use of heating and cooling.

[Summer Trends]

• Electricity bills increase due to air conditioning.
• You can sometimes reduce costs by taking measures to block out the outside temperature while the air conditioner is running (such as using a circulating fan or heat-insulating curtains).
• I often only take showers, so my gas bill is relatively low.

[Winter Trends]

• Electricity and gas bills are soaring due to the use of heating appliances.
• As we take baths more often, our gas bills can nearly double compared to summer.
• The use of dehumidifiers and dryers for drying laundry indoors also has an impact.

Spring and autumn are the seasons when heating and air conditioning are hardly used, making them the times when utility costs are lowest. Being mindful of average spending during these periods makes it easier to manage your budget throughout the year.

Difference in utility costs between urban and rural areas

Utility costs vary by region. Factors that have a particularly significant impact include the type of gas used, temperature, and differences in water rates between municipalities.

[Central Tokyo area (e.g., Tokyo's 23 wards)]

• City gas is widely available, and gas prices tend to be low.
• Many municipalities have relatively low water rates.
• Because there are many apartment buildings and they are well-insulated, heating and cooling efficiency is sometimes good.

[Regional cities and suburbs]

• Many areas use propane gas, which means that gas bills are higher even for the same amount of usage.
• In regions with severe winter cold, heating is used for longer periods.
• Some municipalities have water rates set a little higher than average.

Even with the same usage, it's not uncommon for costs to differ by more than 1,000 yen depending on the region. If you're considering moving, be sure to consider not only rent and floor plans, but also differences in infrastructure costs.

Do consumption trends differ between men and women?

While there are few clear statistics on differences in utility costs between men and women, differences can occur due to tendencies in lifestyle.

[More common in men]

• I don't cook at home very often, so my gas bill is relatively low.
• I often only take showers, so I don't spend much time in the bathroom.
• Because people spend less time at home, their electricity bills tend to be relatively low.

[More common among women]

• Many people are cooking at home, leading to increased use of stoves and microwaves.
• I have a habit of soaking in the bathtub, which tends to increase my gas bill.
• I spend a lot of time at home, and I also use air conditioning and lights for a slightly longer period of time.

Of course, there are individual differences, but the common thread is that daily lifestyle and living patterns directly impact utility bills. It's important to reflect on your own lifestyle and find ways to save money.

Tips for saving money! Techniques for reviewing fixed expenses

Since utility bills are "fixed expenses that are incurred every month," even small savings in a single instance can lead to a significant difference in spending over the course of a year.

This chapter introduces techniques for reviewing fixed expenses that you can immediately implement, even if you live alone. The key to saving money is choosing methods that are manageable and sustainable.

How to review your electricity and gas provider

With the liberalization of electricity and gas markets, many companies now offer these services. Switching from your current electricity or gas provider may result in lower bills.

The following are the points to focus on when reviewing the system:

• Basic charges and usage-based charges (the more you use, the greater the difference).
• Availability of bundled discounts (including integration with mobile phones and internet connections)
• Details of point reward programs (T-points, Ponta, etc.)
• Are there any cancellation fees or contract restrictions?

Using comparison websites and simulators, you can find a plan that suits you in just a few minutes. Since you could potentially save several thousand to ten thousand yen per year, it's definitely worth considering.

Point rewards and app usage

When reviewing your daily expenses, pay attention to your payment methods as well. The following tips can lead to actual savings.

• Switch your electricity, gas, and water payments to a credit card and start earning points.
• Use budgeting apps and electricity usage visualization apps to identify overuse.
• Make it a habit to check your monthly usage and billing amount on your electricity provider's member page and compare it to the same month of the previous year.

To prevent situations where your bill increases without you realizing how much you're spending, visualization is an effective solution. Using an app makes it easier to understand your spending through graphs and numbers, increasing your awareness of saving money.

Strategies tailored to different lifestyles (e.g., night owl/morning person)

Reviewing your electricity and gas usage patterns to suit your lifestyle is also an effective way to save money.

[For those with a nocturnal lifestyle]

• Since electricity usage is high at night, we will consider a time-of-use pricing plan.
• Switching to a plan that offers cheaper electricity rates at night can help reduce costs for things like laundry and cooking.

[For those with a morning routine]

• By getting ready in the morning quickly, you can minimize your use of gas and water.
• Because I am often not at home during the day, I tend to be able to reduce the amount of time I use air conditioning.

Furthermore, people who spend long hours at home during the day, such as those working from home or freelancers, need to take measures to reduce their total electricity bills, such as implementing insulation measures and introducing energy-efficient appliances.

By understanding your own daily routine and adjusting how you use your utilities during peak hours, you can see a difference in your monthly utility bills.

Common traits of people who have low utility bills even when living alone

Even those living alone who manage to keep their monthly utility bills down share common habits and strategies. The key is not simply enduring hardship, but rather "judging whether something is wasteful" and "having habits that naturally lead to saving money."

This chapter will introduce characteristic behaviors observed in people who keep their utility bills down.

Lifestyle rhythm and equipment improvements

People who pay low utility bills often have a well-structured daily routine. They consciously or unconsciously practice a lifestyle that avoids wasting electricity and water. The following are typical examples of such behaviors:

• My daily routine from waking up in the morning to going to bed at night is consistent, which helps reduce wasted standby power and unnecessary appliance use.
• People spend less time at home, and use of home appliances is kept to a minimum when they are out.
• By doing laundry and cooking in batches, I'm reducing the amount of time and frequency I use them.
• Energy-saving equipment such as water-saving showerheads and LED lighting has been installed.

By creating a system that allows us to work efficiently without consciously thinking about it in our daily lives, we are able to minimize our utility costs.

Making spending more visible can raise awareness of spending.

Many people who are good at managing their utility bills have a clear understanding of how much they are using. Their key characteristic is that they grasp the situation through numbers, rather than relying solely on intuition.

• Use a household budget app or utility bill management app to check your monthly expenses.
• Compare the results to the previous month or year and analyze the factors contributing to the increase or decrease yourself.
• Have the mindset to save the money you've saved as "extra money" or use it for another purpose.

This kind of "visualization" allows you to constantly check whether you're wasting electricity or water. Many wastes only become apparent when you see the numbers, so even just checking once can be effective.

Furthermore, the reduction in utility bills itself becomes a source of accomplishment, naturally leading to sustainable saving habits.

Can you live in a place where utilities are included? A new housing option.

As mentioned earlier, utility costs for those living alone can be reduced to some extent with some ingenuity, but if you want to fundamentally reduce the burden, you can choose housing that includes utilities. Recently, the number of shared housing properties that include utilities in the rent has been increasing, and they are gaining popularity because they make it easier to predict fixed costs.

Your choice of property may affect your utility bills.

Even with similar rent and floor plans, monthly expenses can vary significantly depending on whether utilities are included or charged separately. In particular, if electricity, gas, and water have separate contracts and billing, managing household finances can become complicated.

On the other hand, if you choose a property with utilities included, your monthly expenses will be consistent, making it easier to predict your household budget and suitable for those who are not good at managing their spending. This is especially beneficial for the following types of people:

• People who want to keep their monthly variable expenses as constant as possible
• People who find the electricity and gas contract procedures troublesome
• People who want to use things as much as they want according to their lifestyle (e.g., wanting to use heating and cooling without worrying about others)

Advantages and disadvantages of "fixed-price" and "all-inclusive" properties

Properties that include utilities offer the following advantages:

• No need to contract or pay for electricity, gas, or water.
• Paying it together with the rent makes it easier to manage fixed expenses.
• There is no seasonal fluctuation risk (the amount remains constant regardless of summer or winter).

However, there are some points to be aware of.

• In some cases, there is a limit on usage (any excess usage will be at your own expense).
• In some cases, the price is set higher in anticipation of a certain amount.
• There may be restrictions on how it can be used depending on the contract terms and management regulations.

Before signing a contract, it's a good idea to carefully check things like "what is included in the utility bill," "are there any usage limits," and "how does this differ from common area maintenance fees."

Cost benefits unique to shared housing

One type of shared housing that has been attracting particular attention in recent years is "shared housing with utilities included." In addition to lower rent, utilities such as water, electricity, and internet are often included in a fixed monthly fee, allowing for efficient and easy-to-understand budgeting.

In addition, shared housing offers the following advantages:

• Easy to sign up for and cancel, with low initial costs.
• The apartment is equipped with essential amenities for daily life (washing machine, refrigerator, Wi-Fi, etc.).
• Since utility costs are included in the common area maintenance fee, the monthly fixed costs effectively remain constant.

A major advantage is the ability to enjoy a comfortable lifestyle without having to worry too much about water and electricity usage. It's particularly well-suited to lifestyles involving short-term stays or frequent relocation, and can be considered an option that meets the need for a lighter lifestyle and manageable finances.
