The real cost of homeownership
What is the real cost of home ownership each year?
Mortgage payments are the most obvious ongoing expense for homeowners, but there's much more to it. Annual non-mortgage maintenance (or “ANMM”) combines the smaller work a home needs every year with money set aside for the roof, HVAC, water heater, appliances, and other major components that eventually need replacement. At Homekeepr, we think that ANMM is a number that more people should be aware of for their home.
Some years you will spend less. Other years, several large costs can arrive together. The familiar percentage-of-home-value rule is a useful benchmark, but it cannot see the age of your roof, the number of HVAC systems you own, your climate, a private well or septic system, or a kitchen full of older appliances. Those details are what make a budget useful.
This calculator will get you a little closer to understanding the full annual cost of owning your home. To get a more specific number, Homekeepr customers will be able to understand costs associated with their actual home.

Estimate your annual non-mortgage maintenance
The three amounts divide the midpoint of your suggested annual range.
Recurring maintenance covers expected annual work.
Known replacements builds savings for aging roofs, HVAC systems, water heaters, and appliances.
The home-repair cushion stays liquid for urgent, unplanned work. Unspent replacement and cushion money rolls forward.

How it works
Each dollar is spent making your home better and safer.
Recurring maintenance
Square footage, climate, HVAC count, and well or septic ownership influence recurring inspections, cleaning, tune-ups, testing, pumping, filters, and smaller repairs.
Known replacements
This money accumulates for components that wear out over many years so a roof, HVAC system, water heater, or appliance replacement can be planned instead of financed in a panic.
Home-repair cushion
This portion stays liquid for urgent work that does not follow the schedule, including active leaks, loss of heat, failed refrigeration, electrical hazards, and property-insurance deductibles.
What changes the answer
Older systems, severe weather, more equipment, private utilities, installation quality, condition, local labor, and known defects can move the range or the split. Use real inspections, invoices, and quotes whenever you have them.
The three bucket amounts use the range's midpoint as a practical starting target. The lower end assumes a quieter year and good condition; the upper end gives room for ordinary surprises without pretending it covers every emergency.
Why the budget matters
Get the most from your budget + make the most of your home.
Routine maintenance can prevent or delay larger problems, which is why Fannie Mae recommends putting maintenance into the household budget. A small leak found early, a clean HVAC system, or a pump tested before storm season is usually easier to schedule and compare than an emergency repair. Good records also make it easier to use warranties, avoid duplicate diagnosis, and show the next contractor what has already been done.
Maintenance does not guarantee a higher sale price, but condition matters. Fannie Mae notes that an appraisal considers overall condition, including property maintenance and landscaping. A home with documented service, working systems, and fewer visible defects gives buyers less reason to assume hidden neglect or demand last-minute repair credits.
Insurance is another reason to stay ahead of the work, but not because every maintenance task earns a discount. The National Association of Insurance Commissioners explains that homeowners insurance is not a maintenance contract and does not pay for items that simply wear out. Roof age and condition can also affect how an insurer evaluates risk and coverage. Ask your carrier which documented repairs or mitigation upgrades affect eligibility or discounts; do not assume routine upkeep automatically lowers the premium.
Lower the cost
Four ways to reduce ANMM without neglecting the house
DIY the repeatable, low-risk work
Change matched filters, clean accessible drains and appliance coils, test alarms, replace simple weatherstripping, and handle basic cleaning. Leave fuel-burning equipment, electrical panels, unsafe heights, and work beyond your skill level to a qualified professional.
Stop water early
Small roof, plumbing, gutter, grading, sump-pump, and caulk problems can become structural or mold problems. Regular visual checks and inexpensive leak alerts buy time before the damage spreads.
Know exactly what you own
Save model numbers, filter sizes, manuals, warranties, and service history. The right information prevents wrong parts, missed warranty claims, repeat visits, and an hour of paid diagnosis spent reconstructing the house.
Plan before the emergency
Get condition-based quotes while the system still works, compare the full installed cost, and schedule non-urgent work when you have choices. Emergency timing creates rush fees and weak negotiating leverage.
Your ANMM estimate is not destiny. Home age and climate will not change, but preventative work, accurate records, appropriate DIY, warranty use, and earlier replacement planning can reduce how much of the range becomes avoidable damage or emergency spending.
Put the money to work
The age of the house changes the plan
Newer homes still need recurring care, but they usually have more time before major systems reach replacement age. Older homes need more replacement savings, while homes with incomplete records or legacy systems also benefit from a stronger repair cushion.
The calculator handles that allocation automatically. The direction is consistent with Fannie Mae's guidance that newer homes generally need a lower maintenance budget while homes over 30 years old should budget more. Component life also depends on installation, maintenance, climate, and use, as summarized in HUD's housing-component guidance.
Use real replacement math when you have it
Subtract what is already saved from the expected replacement cost, then divide by the years remaining. That annual number replaces the calculator's assumption.
Raise ANMM instead of hiding a shortfall
If a known roof or HVAC deadline needs more than the replacement bucket provides, increase the annual target rather than starving recurring care or the repair cushion.
Reset the component, not the house
A new roof should reset the roof's age. It does not make the wiring, plumbing, HVAC system, or the rest of an older home new again.
This home-repair cushion is not your full household emergency fund. Fannie Mae recommends keeping maintenance savings separate from broader emergency savings, and Freddie Mac suggests building a household emergency fund covering three to six months of regular expenses.
Budget FAQ
Common home maintenance budgeting questions
How much should I budget for home maintenance each year?
A common benchmark is 1% to 4% of home value, but land value and local prices can distort it. Start with a home-specific ANMM range, then replace assumptions with service invoices, equipment ages, condition-based quotes, and what you learn during the first year.
What does ANMM include?
Annual non-mortgage maintenance includes recurring upkeep, savings for known future replacements, and a liquid home-repair cushion. It does not include mortgage payments, utilities, optional remodeling, or a broader household emergency fund.
Why does the age of my home change the savings split?
Recurring maintenance exists at every age, but older homes are more likely to contain components approaching replacement or carrying incomplete records. Home age sets a useful default; the actual ages and condition of the roof, HVAC, water heater, appliances, plumbing, and electrical systems should override it.
Does a newer home still need a maintenance fund?
Yes. New homes still need filters, cleaning, inspections, testing, landscaping, caulk, drainage care, and warranty documentation. The model gives a newer home less replacement pressure, but it still starts saving before the first major system reaches end of life.
How should I budget for a home that is more than 100 years old?
Begin with a larger home-repair cushion, then inventory the actual ages and condition of every major system. A century-old house may have a new roof and HVAC system but still carry more uncertainty around hidden or undocumented plumbing, wiring, structure, and materials.
What if an actual roof or HVAC quote is higher than the calculator allocation?
Use the quote and deadline. Subtract what is already saved, divide the balance by the years remaining, and make that the annual replacement contribution. Increase ANMM if necessary rather than taking recurring care or the repair cushion below a useful minimum.
Does this calculator include a new roof?
It includes a planning reserve that rises with roof age; it does not assume the entire replacement happens this year. Once an inspection identifies a replacement window and price, use that quote and deadline instead of the planning assumption.
Why not just save 1% of the home's value?
Home price reflects land, location, and market conditions as well as the structure. Maintenance is driven more directly by component ages, condition, local labor, climate, and access. The percentage-of-value rule is a benchmark, not a home-specific plan.
How large should my home-repair cushion be?
Use the calculator's home-specific starting contribution and fund the cushion to at least the highest property-insurance deductible you may need to pay. Older homes with incomplete records benefit from a larger cushion. This is separate from a broader household emergency fund.
Will home maintenance lower my insurance premium?
Not automatically. Maintenance can reduce avoidable damage and may help keep the home eligible for coverage, while some mitigation upgrades may qualify for discounts. Ask your insurer which roof, plumbing, electrical, alarm, leak-detection, wind, or wildfire improvements affect the policy.
