Build your home budget around more than principal and interest. Add taxes, insurance, utilities, HOA dues, and a separate monthly reserve for maintenance and repairs; first check which bills your mortgage escrow already covers so you do not count them twice. Then replace estimates with the bills and costs for your specific home and revisit the budget as they change.
What belongs in a homeownership budget?
The Consumer Financial Protection Bureau (CFPB) defines a total monthly home payment more broadly than mortgage principal and interest. Depending on the property and loan, it can include property taxes, mortgage insurance, homeowners insurance, supplementary coverage such as flood insurance, and homeowners association (HOA) fees. Utilities, maintenance, and repairs are additional expenses to plan for, not automatically part of the mortgage payment. CFPB: Figure out how much you want to spend.
| Cost | How it may be paid | How to budget it |
|---|---|---|
| Mortgage principal and interest | Usually paid to the mortgage servicer each month. | Use the current mortgage statement; separate principal and interest from any other amounts collected. |
| Property taxes and homeowners insurance | May be collected by the servicer through escrow and paid on the owner’s behalf, or billed directly to the owner. | Confirm the payment channel and amount. If escrowed, include the amount in the mortgage outflow but do not add the same bill again as a separate expense. |
| Mortgage insurance and supplementary insurance | Payment arrangements vary; check the loan statement and policy bills. Supplementary coverage may include flood insurance. | Include any premiums that apply to the home, whether collected with the mortgage or paid directly. |
| HOA or condominium dues | Often billed separately by the association; confirm the arrangement for the property. | Use the current dues notice and account for any scheduled changes you know about. |
| Utilities | Typically billed by service providers rather than included in the mortgage. | Use actual bills where possible and account for seasonal changes and local rates. |
| Maintenance, repairs, and improvements | Generally paid as work is needed, rather than through a regular mortgage bill. | Set aside money regularly for routine upkeep and unexpected work; estimate based on the home and local costs. |
Escrow is a way to collect and pay certain bills, not a way to eliminate them. Taxes and insurance can rise, which may change the amount collected for escrow; homeowners who pay those bills directly still need to reserve for them. The CFPB also notes that utility and maintenance costs vary with local prices, climate, and features such as a home’s size, code, and energy efficiency. There is no single monthly estimate that fits every property.
How to calculate a realistic monthly budget
- Start with the actual mortgage statement. Identify principal and interest, escrow, mortgage insurance, and any insurance premium collected by the servicer. If the statement does not make an item clear, ask the servicer what is included in the payment.
- Check which bills arrive separately. Review tax notices, insurance policies, HOA statements, and any supplementary-policy bills. Add those direct payments, but not items already included in escrow.
- Use home-specific utility figures. For a home you already own, total recent bills and divide by 12 to get a planning average, while keeping seasonal peaks in mind. For a prospective purchase, ask for historical bills or usage where available and check local providers’ rates. Treat any estimate as provisional because rates and household use can change.
- Create a maintenance and repair allocation. Make a separate monthly transfer to savings for routine upkeep and larger, less predictable jobs. Consider the home’s age and condition, roof and mechanical-system lifespans, climate exposure, local contractor prices, and how much your household can reasonably save. A percentage-of-home-value rule is not established by the sources cited here as a required or universal amount; use a household estimate and adjust it as you learn the home’s actual needs.
- Add the costs and compare them with take-home income. Include the full monthly housing outflow, including bills paid outside the mortgage, then assess whether it leaves enough room for other regular bills, savings, and goals. The CFPB recommends considering how your budget will change after purchase and deciding how much to save each month for emergencies and other goals.
For a quick worksheet, total the monthly mortgage amount, direct-pay taxes and insurance, HOA dues, utility average, and maintenance savings. Convert bills paid less often than monthly into a monthly planning amount—for example, divide an annual premium by 12—while remembering that the cash may still be due as a lump sum.

Why a repair reserve matters
Some home costs are predictable in timing but variable in amount; others arrive without warning. The CFPB notes that owners are responsible for everything from a leaky faucet to a roof replacement and advises keeping an emergency fund. CFPB: Financial considerations of buying a home.
A practical reserve is not a promise that a particular savings balance will cover every repair. It is a way to make irregular expenses less likely to collide with the mortgage and other monthly bills. Keep the maintenance allocation visible as its own budget line, and when a repair uses the reserve, plan how to replenish it.

What national figures can—and cannot—tell you
Broad figures show why it is risky to treat principal and interest as the whole cost, but they are not a substitute for local quotes, bills, or a property inspection.
- Fannie Mae’s March 2022 analysis estimated that non-mortgage costs made up about half of total borrower costs over a typical seven-year ownership period. Its modeled costs included utilities, property taxes, homeowners insurance, routine repairs and maintenance, and major improvements; the non-mortgage estimates drew in part on 2019 American Housing Survey data. This is a model result, not a percentage that applies to every homeowner. Fannie Mae analysis.
- In Fannie Mae’s Q4 2023 national survey of 3,099 consumers, published in July 2024, 67% of homeowners with the relevant cost said their utility costs had increased in the prior year; the corresponding homeowner-reported figures were 57% for homeowners insurance and 56% for real estate taxes. These are reports about perceived changes during that period, not price-index measurements or forecasts. Fannie Mae survey results.
- The U.S. Census Bureau reported median monthly selected owner costs of $2,035 for U.S. homeowners with a mortgage in 2024, compared with an inflation-adjusted $1,960 in 2023. The release said the increase was driven primarily by higher mortgage costs and insurance fees. The selected-cost measure includes mortgage payments, insurance, taxes, utilities, and various fees; it is a national median, not a personal budget target or a maintenance-savings estimate. In 2024, the median share of income spent on selected costs by householders with a mortgage was 21.4%. Census Bureau release and selected monthly owner-cost definition.
Location can make national medians especially misleading. In the Census Bureau’s 2024 data, median monthly selected costs among homeowners with a mortgage were highest in the District of Columbia ($3,181), California ($3,001), Hawaii ($2,937), New Jersey ($2,797), and Massachusetts ($2,755). These state and district figures use the same selected-cost measure; they are comparisons, not recommended spending levels for an individual household.

When to review the budget
Recheck the numbers when a material bill changes or a new expense emerges. Useful triggers include an insurance renewal, a property-tax adjustment, a change in HOA dues, utility-rate changes, or a repair that reveals additional work. An annual review can catch smaller shifts that have accumulated between major events.
Compare the revised total with take-home income and other priorities. If recurring costs rise, decide deliberately whether to adjust discretionary spending, savings targets, or the amount set aside for future repairs rather than assuming the original estimate still holds.
