How Much Should You Budget for Home Maintenance?
The rule of thumb is 1% of your home's value a year — but that number moves a lot depending on the home's age and what's attached to it. Here's how to budget it properly.
Home maintenance costs don't arrive as a monthly bill — they arrive as a $4,000 furnace replacement in the exact month you weren't expecting it. Budgeting for maintenance the way you budget for a mortgage payment, as a fixed monthly amount set aside in advance, is what turns that into a non-event instead of a crisis.
The 1% rule (as a starting point, not a guarantee)
The commonly cited rule of thumb is to budget roughly 1% of your home's current value per year for maintenance and repairs. For a home worth $600,000, that's about $500/month set aside. It's a starting point for a healthy home of typical age and systems — not a ceiling, and not a guarantee against a bad year.
What pushes the number higher
- Age — a home over 20–30 years old is approaching the replacement window for a roof, furnace, and major appliances simultaneously
- Extra systems — a pool, generator, sprinkler system, or well and septic each add their own maintenance line, on top of the base 1%
- Climate exposure — freeze-thaw cycles, heavy snow load, and high humidity all accelerate wear on roofing, foundations, and exterior finishes
- Deferred maintenance — skipping small repairs (a slow roof leak, a cracking driveway) almost always converts them into larger, more expensive ones later
A newer home (under 10 years) with none of the above can often budget closer to 0.5–1%; an older home with a pool and a well can reasonably run 2%+ some years.
Building a maintenance sinking fund
A sinking fund is just a savings account that exists for one purpose — spread the cost of an eventual known expense across the months before it happens, instead of absorbing it all at once.
- Open a separate high-interest savings account, labelled for maintenance only
- Automate the monthly transfer the same way you'd automate a bill payment
- Track big-ticket items separately with a rough replacement year — roof, furnace, water heater, driveway — so a large expense is anticipated, not a surprise
- Use the seasonal maintenance checklist to catch small problems before they become the big-ticket ones the fund exists for

A common rule of thumb is 1% of your home's current value per year, adjusted up for an older home, extra systems like a pool or generator, or heavy climate exposure — and down for a newer home with none of those factors.
