How much should I budget for home maintenance?

The standard answer is "1% to 3% of your home's value per year." It's a fine starting point and a frustrating one — on a $400,000 house that's anywhere from $4,000 to $12,000, which is an $8,000 spread. Here's how to turn the rule of thumb into a number you can actually set aside.

What is the 1% rule for home maintenance?

Set aside roughly 1% of your home's value each year for upkeep. On a $400,000 home, that's $4,000/year, or about $333/month. The logic: over a long enough horizon, routine maintenance plus the occasional big repair averages out to roughly that. Some years you spend nothing; the year the roof goes, you spend it all at once. The fund smooths the lumpiness.

Why 1–3% instead of one number?

The right percentage depends on factors the rule hides:

• Age: an older home trends toward 3%+; a new build sits near 1%.
• Condition: deferred maintenance compounds — neglect raises the number.
• Climate: freeze-thaw, storms, and salt air all accelerate wear.
• Size and materials: more square footage and higher-end finishes cost more to maintain.

A 1990s home in a harsh climate should budget closer to 3%. A renovated home in a mild one can sit near 1%.

What does that actually cover?

Two buckets, and people forget the second:

1. Routine upkeep — filters, gutter cleaning, servicing, small repairs. Predictable, a few hundred to a couple thousand a year.
2. Big-ticket replacements — roof, HVAC, water heater, siding. Rare but expensive, and the reason the percentage looks high. These are the ones worth funding before they fail.

How do I budget for my actual home?

The percentage rule treats every house the same. Yours isn't. The better way: list your major systems, find their age and remaining life, and divide each replacement cost by the years left. A 20-year roof at year 15 with a $12,000 replacement is about $2,400/year you should already be setting aside — just for that one item. Do this for the roof, HVAC, water heater, and you have a real number instead of a percentage.

That's exactly the math Almwell runs from your address: it finds your systems, estimates their ages, and turns "1 to 3 percent" into a funded, item-by-item plan. See our methodology for how we estimate component ages and cost ranges.
