Example 1

Newer home

Recent construction still under some warranties, at the low end of the range.

Monthly reserve

$300.00

Example 2

The 1% rule

The usual starting heuristic for a home in reasonable condition.

Monthly reserve

$400.00

Example 3

Older home

An older property where systems and roof are closer to replacement.

Monthly reserve

$800.00

Sweeps annual maintenance % from half to one and a half times your value, holding everything else fixed.

What this calculates

Suggests a monthly maintenance reserve as a percentage of home value. It is a blunt heuristic, but it is far better than the common alternative of no reserve at all.

How to use it

  1. Start with home value and work down the form, or load an example to begin from a realistic case.
  2. Read the headline result alongside the supporting rows, which show the intermediate figures behind it.
  3. Check the assumptions. They decide what the number includes and, more importantly, what it leaves out.
  4. Sweep annual maintenance % on the response curve to see how much it actually moves the answer.
  5. Run a cautious case as well as an optimistic one before using the estimate in a decision.

Common mistakes

  • Assuming the reserve covers both routine upkeep and major renovations.
  • Skipping the reserve in the early years and meeting the first big repair with a credit card.
  • Scaling the reserve to a rising home value while the actual house does not change.

Formula

Monthly reserve = (home value × annual maintenance %) ÷ 12

Inputs

  • Home value
  • Annual maintenance % (%)

FAQ

Is 1% always enough?

No. It is a starting heuristic, and it scales with value rather than with what actually breaks. Track your real spending for two years and replace the guess with your own number.

Should the reserve be based on value or on square footage?

Both are approximations. A per-square-foot figure often tracks reality better, because a roof costs what it costs regardless of the neighbourhood. Use whichever produces the more conservative number.

Does this cover renovations?

No. This is upkeep: repairs, servicing, and replacing things that wear out. Renovations are discretionary projects and belong in the renovation contingency budget calculator.

Are these numbers financial advice?

No. They are educational estimates based on the inputs and assumptions on this page. Confirm important decisions with a qualified professional and your own documents.
