Use the file when you want a record you can return to. The Budget tab holds your projects and totals. The second tab explains each field and links to the consumer guidance behind the planning approach. You can enter figures in one currency, save the file, and update it when a quote or timeline changes.
If you are still deciding what monthly amount to set aside, read the home maintenance budgeting walkthrough first. It shows how recurring upkeep and known project costs fit into one plan.
Fill one row per planned expense
- Name the work. “Replace the main refrigerator” is more useful than “appliances.” If the scope is still undecided, say so in the last column.
- Enter an expected cost you can trace. Start with a written estimate for the work you actually expect to buy. Put the contractor, document, or estimate source and its date beside the amount. The FTC says a written home-improvement estimate should describe the work, materials, completion date, and price.
- Enter only savings assigned to that project. If the same cash is also meant for another job, counting it in both rows makes the plan look cheaper than it is.
- Use months until you expect to pay. This is a planning date, not a prediction of when equipment will fail. When timing is uncertain, save a copy of the file and compare an earlier and a later date.
Leave an unknown cost or payment date blank. The row will ask for the missing input, and the combined monthly target will stay blank until entered rows are complete. A zero would imply that you have an estimate of no cost.
Keep routine upkeep separate
The annual routine-upkeep field is for recurring work you expect to pay for during the year. The workbook divides that amount by 12 and adds it to the monthly targets for planned projects. It does not mix in property tax, insurance, utilities, or a general emergency fund. The Consumer Financial Protection Bureau advises homeowners to budget for maintenance and repairs and to think separately about saving for emergencies and other goals.
There is no preset percentage of home value in this file. Location, climate, the home itself, and the work you intend to do can change what you spend. A quote and a date give you a clearer starting point than a universal rate.
What the monthly target means
For each project, the sheet subtracts the money already saved from the expected cost, stops at zero if savings cover that cost, and divides the remainder by months until payment. It adds the project amounts and one-twelfth of your annual routine-upkeep amount.
Project monthly target = max(0, expected cost − already saved) ÷ months until payment
The number is a savings schedule under your current assumptions. It is not a forecast of future prices or a recommendation to delay work. If it is more than you can set aside, revisit the quote, scope, and timing with the relevant professional. The sheet cannot decide whether a safety issue is suitable to postpone.
Use the worksheet with the site’s tools
The maintenance reserve calculator is faster for trying several cost or timeline scenarios in your browser; it can export the result as a CSV plan. The workbook is for keeping the estimate source and your next action beside the numbers. Neither tool fills in market prices for you.
If two bids cover different work, use the contractor quote comparison tool before choosing the amount to put in this sheet. If you are still deciding whether to repair or replace a system, start with the repair-or-replace calculator. Then budget for the option you actually plan to pursue.
Sources, privacy, and limits
The CFPB’s homeownership budgeting guidance supports planning for maintenance, repairs, utilities, and other savings goals. The FTC’s home-improvement guidance explains what to look for in a written estimate. These are U.S. sources; check local contractor and consumer rules elsewhere. Neither supplies the project prices, dates, or amounts in your sheet. Sources checked October 2, 2026.
The formulas are described in the site method. The file does not model price changes, financing, emergencies, returns on savings, or the need for work. It is a static download: values you enter into your copy are not sent to Homeowner Cost Lab. If you choose to store or share the file elsewhere, that service's terms apply.
