FUNDPILOTHow to read an HOA reserve study
A reserve study is only as useful as your ability to read it. This guide walks through the five sections that matter, the numbers to check first, and the red flags that mark a weak study.

Start with percent funded, not the balance
The single most quoted number in a reserve study is percent funded: your actual reserve balance divided by the fully funded balance. It strips out association size so a $200,000 balance means something different in a 40-unit community than a 400-unit one.
| Percent funded | Health | What it means |
|---|---|---|
| Below 30% | Weak | Special assessment risk is real. Component failures cannot be absorbed. |
| 30% - 70% | Fair | Workable, but a major component failure hurts. Raise contributions on a plan. |
| Above 70% | Strong | Reserves track the depreciation of the components. Most boards target this band. |
| Above 100% | Over-funded | More cash than accumulated depreciation. Not a problem, but check opportunity cost. |
The thresholds come from reserve industry practice, popularized by firms like Association Reserves and the Association of Professional Reserve Analysts. No statute defines them, but lenders, insurers, and courts all read them the same way.
The fully funded balance, in one paragraph
The fully funded balance (FFB) is what your reserve account would hold if you had set aside each component's depreciation since installation. For each component: cost, multiplied by effective age, divided by useful life. Sum it across the inventory and you have the target. A $400,000 roof at year 20 of a 25-year life has consumed 80 percent of its cost: $320,000 of the FFB comes from that roof alone. When a study says the association is "48 percent funded," it means the actual balance is 48 percent of that accumulated target.
The cash flow projection is the real story
Skip to the 20 or 30 year cash flow table. It shows, year by year: contributions in, repair expenditures out, interest earned, and the ending balance. Two lines matter most: the lowest balance in the projection (does it ever go negative?) and the trajectory of percent funded over time (rising, flat, or falling).
A study that never goes negative on paper but shows percent funded sliding from 60 to 30 over 30 years is quietly getting weaker every year. The balance only looks safe because big replacements sit past the projection horizon. Look for the first year the balance dips below about one year of contributions: that is your early warning line.
Funding methods: full, threshold, baseline
The study's recommendation depends on which method the preparer used, and the choice changes the monthly number more than almost any assumption:
| Method | Goal | Trade-off |
|---|---|---|
| Full funding | Reach and hold ~100% funded | Highest contributions, lowest risk |
| Threshold funding | Never drop below a set floor (e.g. 60%) | Mid contributions, flexible |
| Baseline funding | Balance stays just above $0 every year | Cheapest, no cushion, small errors hurt |
| Straight-line (goal-based) | Hit a target % funded by a chosen year | Predictable path, easy to explain to owners |
Ask which method your study used before comparing its recommended contribution against another study's. A baseline-funded recommendation can be half of a full-funded one for the identical community.
Red flags in a weak study
Five marks of a study to distrust: no stated inflation or interest assumptions; component costs in stale dollars with no escalation; a projection shorter than 20 years; an inventory missing obvious items like roads, roofs, or pools that the community clearly owns; and a percent funded figure with no FFB math behind it. Any one of these is a reason to ask the preparer for the working file.
Reading it in the tool instead of the PDF
Every number above is something FUNDPILOT computes live from your study PDF: percent funded per year, the FFB line against your balance, expenditure pressure by year, and the contribution each funding method implies. Upload the PDF once and drag the assumptions instead of re-reading static tables. Curious what a new study costs first?

Frequently asked questions
What is a good percent funded number?
The rule of thumb used by reserve professionals: below 30 percent is weak, 30 to 70 percent is fair, and above 70 percent is strong. Above 100 percent means you hold more than the fully funded balance, which is fine. The real question is the trend: a plan that reaches 70 percent by 2035 is healthier than a flat 40 percent forever.
What is the fully funded balance (FFB)?
The fully funded balance is the accumulated depreciated value of your components: for each component, its replacement cost multiplied by its effective age divided by its useful life, summed across the inventory. Percent funded is simply your actual reserve balance divided by the FFB.
Which funding method should our HOA use?
Full funding (targeting 100 percent funded) is safest but costs the most per month. Threshold funding sets a minimum percent funded floor. Baseline funding aims to keep the balance just above zero, which is cheapest and riskiest. Straight-line funding, which solves for a fixed contribution that hits a target percent funded by a date, is a common compromise.
How do I know if a study's assumptions are reasonable?
Check the inflation assumption (typically 2 to 4 percent), the interest rate on reserves (conservative, under 5 percent), and whether component costs were escalated from a stated base year. A study with no stated assumptions, or costs that never inflate, is a red flag.
