Percent Funded Calculator

Percent funded is your reserve balance divided by your fully funded balance — the single number that tells an HOA board how healthy its reserves are. Enter two numbers below (or let the guided mode estimate your fully funded balance) to see where your community stands. Above 70% is strong; below 30% signals elevated special-assessment risk.

The definition

Percent funded = current reserve balance ÷ fully funded balance × 100

An HOA holding $180,000 against a $300,000 fully funded balance is 60% funded. The fully funded balance is the deterioration your components have already accrued: each contributes replacement cost × (age ÷ useful life). For the full theory — including how to raise your number over 5–10 years — read Percent Funded, Explained.

Your numbers

Two inputs: your balance, and what a fully funded reserve would hold.

The formula, in plain English

Percent funded = reserve balance ÷ fully funded balance × 100

The fully funded balance is what your reserves would hold if every component had been funded exactly in step with its aging: each component contributes replacement cost × (age ÷ useful life). It is the standard benchmark used by professional reserve studies under CAI's National Reserve Study Standards.

Percent funded is a snapshot, not a plan

It tells you where you are — not what to contribute next year. For that, run the full reserve fund calculator, which projects your balance 30 years forward and recommends an annual contribution using both standard funding methods.

What your percent funded result means

The industry sorts percent funded into three bands, and they aren't arbitrary — they come from decades of Association Reserves data on which communities end up levying special assessments.

Percent fundedBandWhat it predicts
0–30%WeakHigh special-assessment risk — levies are common in this range. About a third of associations sit here, and a failed roof or elevator typically forces an emergency assessment of thousands of dollars per door.
30–70%FairSpecial assessments are infrequent but real. Roughly 40% of associations fall in this band; a cost overrun or a component failing early can still push a fair community into a levy.
70–100%StrongSpecial assessments are rare — Association Reserves puts the odds under 5% for communities that stay in this range. Only about a quarter of associations are here.

You don't need 100% to be safe — the risk curve flattens dramatically above 70%, which is why most boards target that threshold. If your community is in the weak band, run the special assessment calculator to see what a levy would actually cost each owner.

Worked example: is $180,000 in reserves good?

A raw dollar balance tells you almost nothing — $180,000 could be strong for a 40-home community or dangerously thin for a 200-unit condo. Percent funded puts it in context. Take a community with three reserve components:

  • Asphalt shingle roof: $150,000 replacement cost, 25-year useful life, 15 years old. Accrued share = $150,000 × 15 ÷ 25 = $90,000.
  • Private road overlay: $200,000 replacement cost, 20-year useful life, 15 years old. Accrued share = $200,000 × 15 ÷ 20 = $150,000.
  • Pool resurfacing: $60,000 replacement cost, 12-year useful life, due this year. Accrued share = the full $60,000.

Adding the three shares gives a fully funded balance of $300,000. With $180,000 in the reserve account, this community is $180,000 ÷ $300,000 = 60% funded — squarely in the fair band. A special assessment isn't imminent, but with the pool due now and the road only five years out, the board should be planning a path to 70%+ rather than coasting.

The calculator above runs this exact math from your own balance and components. For what to do with the result — including a catch-up plan that costs $16–$31 per home per month — see the full guide, Percent Funded, Explained.
