How to set a maintenance reserve
Use value and age to size a practical annual fund.
Enter the home value
Use a realistic current market value or your latest assessment.
Choose the age band
Older homes need a larger reserve for roofs, wiring, plumbing and windows.
Adjust the rate
Set the percentage you can sustain, then build the fund monthly before repairs are urgent.
What does this tool do?
A common rule of thumb is to budget about 1% of a home value each year for maintenance and repairs. Older homes typically need more, and the spend is lumpy: a quiet year can be followed by a new roof.
The Formula
Annual budget = home value × rate % × age factor; monthly = annual ÷ 12Frequently Asked Questions
Is 1% of home value enough?
It is a reasonable baseline for many homes, but not a rule. Older properties, large lots, pools and extreme climates often need more; track actual costs for two years to calibrate.
Should maintenance savings be invested?
Keep the reserve in a liquid, low-risk account. The point is availability when the water heater fails, not maximising return.
