Home repair planning

How Much Should You Save for Home Repairs?

Build a monthly reserve from the maintenance your home actually needs, the major repairs or replacements you can see coming, and any money already available for those costs.

This can be part of a larger savings or emergency account. A separate bank account is not required.
Use expected annual spending for smaller upkeep, servicing, and recurring maintenance.
Optional. Used only to show Fannie Mae's broad 1%–4% annual rule-of-thumb range.

Major repairs and replacements

Add costs you can reasonably anticipate. Use an inspection report, contractor estimate, warranty, manufacturer information, or your own planning estimate when available.

Up to 8 major repairs or replacements can be modeled.

Your monthly home-repair plan

Routine maintenance is treated as recurring spending. The major-repair portion solves for the smallest fixed monthly contribution that keeps the planned replacement reserve from falling below zero at each listed expense date.

Total monthly set-aside — Routine maintenance plus planned major repairs
Routine maintenance portion — Annual routine budget divided by 12
Major-repair reserve portion — Monthly contribution needed under the listed timing
Annualized plan — Monthly total multiplied by 12

Planned major repairs

Current repair reserve —
Listed major costs — Major repairs and replacements included
Earliest listed expense — Timing of the first planned major expense
1%–4% home-value reference — Broad annual comparison only, not the calculator target

Major-repair timeline

The projected balance below includes only the current repair reserve and the calculated major-repair contribution. Routine maintenance is shown separately because it is treated as recurring spending rather than a future replacement balance.

How this calculator works

Routine monthly amount Annual routine maintenance ÷ 12
Major-repair contribution Highest cumulative shortfall ÷ months until that expense

Major repairs are sorted by expected timing. At each listed date, the calculator compares cumulative planned costs with the current repair reserve plus equal monthly contributions. The largest monthly contribution required at any point becomes the major-repair reserve amount.

Interest is not modeled. Repair timing and costs are estimates, and several expenses can arrive earlier, later, or together. Revisit the plan when contractor estimates, inspection findings, warranties, or the condition of the home change.

The home-value percentage is shown only as a broad comparison. Fannie Mae describes 1%–4% of home value per year as a rule of thumb for maintenance, repairs, and replacements. A component-based plan can reasonably land above or below that range.
