Home Maintenance Budget Calculator
Example: Home value: 400000 $ · Home size: 2200 sq ft · Home age: 25 years
| Annual maintenance budget | $3,410 |
| Monthly amount to set aside | $284 |
| 1% rule figure | $4,000 |
Worked example
A $400,000, 2,200-square-foot home gives a 1% figure of $4,000 and a square-foot figure of $2,200. Averaging them yields $3,100. Because the home is 25 years old, the calculator applies a 10% bump to about $3,410 a year, or roughly $284 a month to bank. A 40-year-old home would get a larger 20% adjustment, reflecting the heavier upkeep older systems demand.
Frequently asked questions
What is the 1% rule for home maintenance?
It suggests setting aside about 1% of your home value each year for maintenance and repairs. A $400,000 home implies roughly $4,000 a year. It is a starting estimate, not a guarantee — some years cost far less, others far more when a big system fails.
Why does home age matter?
Older homes have older roofs, HVAC, plumbing, and electrical systems that are closer to the end of their service lives, so they need more repairs and replacements. This calculator raises the budget modestly for homes over 15 and 30 years old.
What counts as maintenance versus improvement?
Maintenance keeps existing systems working — servicing the furnace, replacing a worn roof, fixing plumbing. Improvements add new value, like a remodel. Budget for both separately; this tool covers routine and inevitable upkeep, not discretionary upgrades.
Should I keep this money in a separate account?
Many homeowners do, funding a dedicated repair reserve monthly so a five-figure roof or HVAC bill is already covered. Treating the monthly figure here like any other fixed cost is what prevents maintenance from becoming credit-card debt.
