Key takeaways
How much an association should hold in reserves is measured by percent funded: the reserve balance divided by the fully funded balance, the share of each component's replacement cost already used up by age. Many boards treat 70% or higher as strong and below 30% as high risk. The annual contribution rate, set by the study's funding strategy, determines where the balance goes next.
- Percent funded equals the current reserve balance divided by the fully funded balance.
- A common rule of thumb treats 0-30% funded as weak, 30-70% as fair and 70% or higher as strong.
- Funding strategies include full funding, threshold funding, baseline funding and statutory funding; Fannie Mae no longer accepts baseline funding for its reserve study alternative.
- Fannie Mae's minimum reserve contribution rises from 10% to 15% of assessment income for condo loan applications dated on or after January 4, 2027.

"How much should we have in reserves?" sounds like it should have a dollar answer. It doesn't, because a $500,000 balance is excellent for one community and dangerously thin for another. What boards need is a ratio that compares what they have to what they should have, and a contribution rate that moves them in the right direction.
Percent funded: where you stand today
Percent funded = current reserve balance ÷ fully funded balance
The fully funded balance is the portion of each component's replacement cost that has already been "used up" by age. For each component:
Fully funded balance = current replacement cost × (effective age ÷ useful life)
A worked example
| Component | Replacement cost | Useful life | Age | Fully funded balance |
|---|---|---|---|---|
| Roof | $300,000 | 25 yrs | 10 yrs | $120,000 |
| Paving | $150,000 | 20 yrs | 15 yrs | $112,500 |
| Pool resurfacing | $60,000 | 12 yrs | 6 yrs | $30,000 |
| Total | $262,500 |
If the association has $170,000 in reserves, it is 65% funded ($170,000 ÷ $262,500).
What the number means
A widely used rule of thumb:
| Percent funded | Typical read |
|---|---|
| 0–30% | Weak. Higher risk of special assessments or deferred projects |
| 30–70% | Fair. Manageable, but the trend and upcoming expenses matter |
| 70%+ | Strong. Lower risk of special assessments |
We explain why many boards target this range in Why Is a 70% Funded Reserve Ideal? Percent funded is a snapshot, though. A community at 60% with a rising trend and no major projects coming may be safer than one at 75% with a façade replacement next year. Read it alongside the 30-year cash flow.
Contribution rate: where you're going
The contribution rate is the amount the association deposits into reserves each year, set by the funding strategy the board adopts from its reserve study.
| Strategy | Goal | Trade-off |
|---|---|---|
| Full funding | Reach and hold about 100% funded | Highest contributions; lowest risk |
| Threshold funding | Never fall below a set percent or dollar floor | A middle path; the board picks the floor |
| Baseline funding | Keep the balance above $0 in every year | Lowest contributions; least cushion, and higher special assessment risk |
| Statutory funding | Meet a state's legal minimum | Compliance floor, not necessarily a sound plan |
A good study models more than one strategy so the board can weigh dues against risk with real numbers.
Where law and lenders set the floor
- Hawaii: condos must fund at least 50% of estimated replacement reserves.
- New Jersey: a 30-year plan funded at 100%, or a temporary 85% option.
- California: AB 2050 mandates minimum reserve funding starting January 1, 2032.
- Michigan: condo reserves of at least 10% of the annual budget.
- Delaware: full funding over 20 years for condos and co-ops, with 5–15% budget minimums if there's no current study.
- Fannie Mae (LL-2026-03): for condo loan applications on or after January 4, 2027, the budget must allocate at least 15% of assessment income to reserves, up from 10%. Associations below that can qualify with a reserve study from the past three years only if the budget funds the study's highest recommended contribution, and baseline funding no longer qualifies.

Moving from underfunded to stable
If your percent funded is low, the fix is rarely one dramatic vote. It's usually:
- Get a current study. You can't plan from stale costs.
- Model scenarios side by side. Compare a threshold plan and a full-funding plan over 30 years.
- Phase increases. Steady, explained increases are easier on owners than a single special assessment.
- Sequence projects. Moving one project by a year can flatten the curve.
- Show owners the math. Clear data reduces board conflict and homeowner distrust.
Watch it change in real time
Percent funded moves every month as balances grow, costs change and projects are completed. In The Living Reserve Study®, your percent funded, cash flow and contribution scenarios update as you record those changes, so the board can test a dues decision before the budget meeting, not after. Book a demo to see it with your numbers, or request a proposal for a current study.
