Reserve study vs. reserve fund: what's the difference?

A reserve study is a document: a professional plan that inventories what your community must eventually replace, estimates when and at what cost, and recommends how much to save. A reserve fund is money: the actual account where those savings sit. The study is the plan; the fund is the balance. They're related the way a fitness program relates to your fitness — one prescribes, the other is the state of things — and it's entirely possible to have either one without the other.

The two get conflated constantly in board meetings, budget mailings, and real estate listings, and the confusion isn't harmless: a board that says "we have healthy reserves" might mean either "we have a recent study" or "we have money in the bank," and neither statement alone means the community is prepared.

The reserve study: the plan

The study is prepared by a reserve specialist, usually every one to three years, and contains four working parts: an executive summary, a component inventory with useful lives and replacement costs, a funding analysis, and a multi-year cash-flow projection. Our guide to reading your reserve study walks through every section.

The critical thing about the study is that it obligates nothing by itself. It's a recommendation. The preparer can conclude your community should contribute $52,000 a year, and the board can adopt a budget that contributes $30,000. The document doesn't move money — people do, through the annual budget.

The reserve fund: the money

The fund is one of the two accounts every association runs — the other being the operating fund that pays the recurring bills. Operating funds vs. reserve funds covers that split; the short version is that the reserve fund is the community's savings account, earmarked for the large, infrequent replacements the study identifies: roofs, paving, boilers, elevators.

The fund grows through the reserve contribution — the slice of each owner's dues the budget routes into it — and shrinks when projects are paid for. It should live in its own account, separate from operating cash: kept liquid enough to pay for the next few years of projects, and never quietly borrowed from to cover an operating shortfall without a documented repayment plan. Its balance on any given day is a plain fact you can read off a bank statement. What the balance means, though, you cannot know from the statement alone.

Percent funded: where the two meet

Here's the connection. The study calculates a fully funded balance — what the account should hold today, given how much life your components have already used up. Percent funded is the actual fund balance divided by that number.

Work the example: your study's component inventory implies a fully funded balance of $800,000. Your reserve fund holds $320,000. You are 320,000 ÷ 800,000 = 40% funded — regardless of whether $320,000 sounds like a lot of money. The same $320,000 balance in a newer community whose fully funded balance is $400,000 would be a healthy 80%.

That's why neither document nor account is meaningful alone. The fund supplies the numerator; the study supplies the denominator. A community that skips the study can't compute the fraction at all — it just has a balance and a feeling.

One without the other: the two failure modes

A fund without a study. The board contributes "what we've always contributed," the balance grows, and everyone feels prudent — until the boiler, the roof, and the elevator modernization land in the same five-year window the way an inventory would have predicted. The balance was real; the sense of security wasn't. This is how communities with six figures in the bank still end up levying special assessments.

A study without a funded plan. The opposite failure is the study that gets commissioned, delivered, discussed once, and shelved, while the budget keeps contributing a fraction of the recommendation. The plan exists; the money doesn't. Every year the gap between the recommended and actual contribution compounds, and the risks of underfunding — deferred maintenance, falling values, assessment shock — accumulate quietly behind a document that technically exists.

Healthy communities close the loop: the study sets the target, the budget funds it, and the next study update checks the aim.

Which one does the law care about?

Mostly the study. Where state law regulates reserves at all, it usually mandates the planning — whether a study is required, at what interval, with what disclosure — and stays silent on how much the fund must hold. California is the clearest example: associations must conduct a reserve study with a visual site inspection at least every three years and review it annually (Civ. Code §5550, verified September 2026), but no California statute sets a minimum percent funded. Florida went a step further for condominium buildings three stories and taller after Surfside: associations may no longer waive or reduce reserves for structural components (SB 4-D, verified September 2026) — a rare case of the law reaching the fund itself.

Lenders care about both. Buyers' mortgage underwriting on condos increasingly asks what the association holds and how it plans — another reason the two need to agree.

How to check both in your community

Five minutes with two documents tells you where you stand:

1. Find the study. Ask when it was last done and whether it included a site visit. Older than three years, or desk-updated for years on end, means the plan itself is stale.
2. Find the balance. The reserve fund appears as its own line on the balance sheet in your budget packet — separate from operating cash. If it doesn't appear as its own line, that's a finding in itself: ask the treasurer where reserve money actually sits.
3. Divide. If the study is current, it states the fully funded balance and the percent funded figure outright. Confirm the balance it used matches the real account today.
4. Compare contributions. The study's recommended annual contribution vs. what the current budget actually transfers. This gap is the single most honest indicator of whether your community is executing its plan or just filing it — and it compounds. A community whose study recommends $52,000 a year but whose budget moves $30,000 falls $22,000 further behind annually: five years of that is a $110,000 hole before inflation widens it, roughly the price of the boiler the study was saving for.

If the answers are "there is no study" or "nobody knows," that's not a bookkeeping quirk — it's the first project to fix.
