How much does home maintenance cost per year? The rules of thumb and the published figures behind them

Fannie Mae’s maintenance budget guide gives a rule of thumb of 1% to 4% of the home’s value per year, covering maintenance, repairs and replacements. On its own example of a $350,000 home, that is $3,500 a year at 1% and $14,000 a year at 4%.

The range is wide on purpose. Fannie Mae says 1% should be enough for a new home, and that an owner of a home more than 30 years old may do better to lean toward 4%. The US Consumer Financial Protection Bureau takes the simpler line in its monthly payment worksheet for home buyers, which calls 1% of the target home price a common rule of thumb and tells buyers to divide it by 12.

Survey data on what people spend comes out lower than the rules suggest. Angi’s 2025 State of Home Spending report put average maintenance spending at $2,041 per household, up from $1,750 in 2024, with a further $1,143 on emergency repairs. The same report counts improvement projects separately, at $9,288 per household.

The two kinds of figure measure different things. The percentage rules describe what to set aside so that a large replacement can be paid for when it comes. The survey describes what households paid out in one year. A year with no large replacement will always look cheaper than the long-run average.

It is a reasonable starting figure and a weak prediction for any one house. The rule ties the budget to the price of the home, but the price mostly reflects land and location, while the maintenance bill depends on the building: its age, its size, its materials and the equipment inside it.

Two homes with the same price can need very different amounts of work. A flat in a new block and an old detached house on a large plot may sell for the same sum. One has a roof, gutters, a chimney and a garden to look after, and the other shares most of those costs through a service charge.

This is why the sources that publish the rule also qualify it. Fannie Mae attaches the age of the home to its range. The CFPB presents 1% as a figure for a first-time buyer’s worksheet, to be replaced by better numbers later. Treat the percentage as the first line of a budget and expect to correct it.

Age matters most in the published guidance: Fannie Mae points owners of homes over 30 years old toward the top of its 1% to 4% range. After that come the size of the building, the climate, the equipment you own, and whether you do the simple jobs yourself or pay for each visit.

• Age. Newer homes tend to have lower average maintenance costs, in Fannie Mae’s words. In an older home, more of the large components are close to the end of their published lifespans at the same time.
• Size. Cost guides price much of the work by area. HomeGuide’s roof figures run from $3,500 to $6,700 for a 1,000 square foot house up to $13,400 to $26,800 for a 4,000 square foot house.
• Climate and location. HomeGuide lists location and climate among the factors that set the price of a furnace replacement. Labour rates also differ from one area to the next, so national averages are only a guide.
• Equipment you own. A pool, a septic system, a well, a fireplace or a water softener each adds its own recurring jobs. Maintainly’s task library keeps these as separate tasks tied to the equipment, so they apply only to homes that have it.
• Who does the work. Changing a filter costs the price of the filter. A professional service costs a call-out. Gas, electrical and roof work should go to a qualified professional whatever the saving.

Routine maintenance is the predictable part of the budget, and for most homes it is the small part. Published cost guides put a furnace tune-up at $70 to $200 or more in the US and a gas boiler service at £80 to £120 in the UK. The filters and checks in between cost little.

Routine work is the set of jobs that repeat on a schedule whether or not anything is wrong. The intervals below are the defaults in Maintainly’s task library, which the home maintenance guides explain task by task. The costs are published national ranges and will differ where you live.

For the filter, ENERGY STAR’s heating and cooling maintenance checklist goes further than the library default and says to inspect, clean or change it once a month. It also recommends a contractor check-up of the cooling system in spring and the heating system in autumn.

Replacements are where most of the money goes. HomeGuide’s average US ranges are $5,700 to $16,000 for a roof, $3,500 to $7,500 or more for a standard furnace and $600 to $3,100 for a tank water heater. Its published lifespans run from 8 to 12 years for a tank water heater to 20 to 30 years for architectural shingles.

The table sets each replacement cost beside its published lifespan. The last column is our own arithmetic: the lowest cost divided by the longest lifespan, and the highest cost divided by the shortest. It shows roughly what one component costs per year of its life.

Sources: HomeGuide’s cost guides for roof replacement, furnace replacement and water heater replacement, and Checkatrade’s new boiler cost guide for the UK. HomeGuide says its figures come from research and from project costs reported by its members.

Added together, the yearly shares of a roof, a furnace and a water heater come to several hundred dollars at the low end and well over a thousand at the high end, before any routine work. That is the gap between a quiet year’s spending and what the percentage rules tell you to save.

The published sources say it does, though none of them puts a reliable number on the saving. ENERGY STAR says a dirty filter can damage heating and cooling equipment and lead to early failure. HomeGuide says a tank water heater can reach 15 years with proper maintenance, against 8 to 12 years on average.

The lifespans in the table above come with that condition attached. HomeGuide’s 15 to 30 years for a furnace is stated as the figure with proper maintenance, and it notes that many manufacturers require an annual tune-up to keep the warranty valid. Its 15 to 20 years for a tankless water heater assumes routine flushing and descaling.

Tradespeople make the same case in stronger terms. In Money Magazine’s June 2026 feature on the cost of owning a home, a Sydney plumbing contractor said more than half the cost of major repairs can typically be avoided with proper maintenance. That is one contractor’s estimate, not a measured figure, and we have not found a study that confirms it.

What can be said with confidence is narrower. You cannot choose whether a roof or a water heater wears out. The routine jobs are the part of the bill you control, and they are cheap next to the replacements they are meant to delay. The guides on how often to replace a furnace filter, how often to flush a water heater and how often to clean gutters cover the three that matter most to the big components.

Start with a percentage rule, then replace it with your own numbers. Take 1% of the home’s value for a newer home and more for an older one, divide by 12, and save it monthly. Then list your large components with their ages, and record what you spend for a full year.

1. Pick a starting figure. Use 1% of the home’s value if the home is new, and move toward 4% if it is more than 30 years old, as Fannie Mae suggests. Divide by 12 and set up a monthly transfer to a separate savings account.
2. List the large components and their ages: roof, furnace or boiler, water heater, air conditioner. Compare each age with its published lifespan. Anything close to the end of its range is a cost to plan for now.
3. Get a local quote for anything due within five years. National ranges are wide, and a real quote for your house replaces a guess.
4. Put the routine jobs on a schedule so they are not skipped. A maintenance schedule that survives real life is mostly a matter of reminders arriving before the due date.
5. Record what each job costs for a year, with the receipts. Fannie Mae gives the same advice: tracking your spending on regular tasks shows how much to set aside. The same records are useful later, as the article on maintenance records that help you sell explains.
6. Keep the maintenance fund apart from general emergency savings. Fannie Mae suggests one fund for the home and another for events such as a job loss or a medical bill.
