Nonprofit Cash Reserves: What Organizations Actually Hold

Every guide to nonprofit finance, this site included, tells you to watch months of cash on hand and quotes three to six months as the target. None of them say what organizations actually hold, because the figure is not published anywhere. So we calculated it from the tax returns.

The answer is not the one the advice implies. The median is five months, which sounds reassuring, and the distribution underneath it runs in the opposite direction to what almost everyone assumes.

Where these numbers come from

The IRS publishes an annual extract of financial data from every Form 990 it processes. It is free, it is not a sample, and it is not a survey: it is what organizations told the government under penalty of perjury.

The processing year 2024 file contains 345,365 returns. Filtering to 501(c)(3) organizations with at least $10,000 of annual expenses leaves 259,062 organizations, which is the basis for everything below.

Months of cash is cash and equivalents divided by one twelfth of total functional expenses. Cash and equivalents means the two balance sheet lines an organization could spend this month: non-interest-bearing cash, and savings or temporary cash investments.

Months of cash, by budget size

Across every filer, 35.7% hold under three months of cash and 16.2% hold under one month. One month means that if the money stopped arriving, payroll is the immediate problem rather than a future one.

The pattern runs backwards from the advice

The reserves conversation is almost always addressed to small organizations, on the assumption that they are the ones running close to the line and large institutions have the buffer. The data says the reverse, and not marginally.

Median months of cash falls at every step up in size: 16.4 months under $100k, then 6.5, 4.7, 3.9, 2.7, and 1.5 months above $25m. The share holding under three months rises the same way, from 18.5% to 70.1%.

Seven out of ten of the largest organizations in the country hold less than three months of cash. If the three to six month rule described real practice, it would be a rule that most large nonprofits break and most tiny ones exceed several times over.

The bottom quarter is the part worth looking at

Medians describe the middle and the middle is not where the risk sits. The 25th percentile column is the more uncomfortable read.

A quarter of organizations spending between $1m and $5m hold 1.6 months of cash or less. A quarter of those above $25m hold 0.5 months or less, which is around a fortnight of operating costs for institutions with hundreds of staff. Across all filers a quarter hold under 1.8 months, and 16.2% hold under one month.

That last group is roughly 42,000 organizations. Some of them are genuinely fine: a university department style operation drawing on a parent body, or an organization whose income arrives on a contract the week after year end. Many are not, and the difference is invisible from the outside, which is the honest limit of any ratio calculated from a public filing.

It does mean that when a funder, a merger partner or a journalist looks at this number for your organization, an answer is worth having ready.

The obvious objection, tested

The first response any finance professional will have is that large organizations do not keep liquidity in a current account. They hold investments, and cash on the balance sheet understates what they could actually reach.

That is a fair objection, so we recalculated including securities and other investments. It moves the numbers and it does not overturn the finding.

On the broad measure the gradient is gentler but it still points the same way, from 33.5 months down to 4.7. Adding investments raises the smallest organizations more than the largest, which is the opposite of what the objection predicts.

It also overstates the position at the top, because investments include endowment principal, and endowment principal cannot lawfully be spent to cover a bad year. An organization with $50m of restricted endowment and three weeks of cash has three weeks of cash. That distinction is the subject of net assets, and it is why the narrow measure is the honest headline.

Why larger organizations hold less

Three explanations fit the data, and they are not competing.

Predictability. A $40m hospital or university knows its revenue months ahead. A $60,000 all-volunteer organization might receive most of its income in one appeal and has no way to smooth it, so cash sits in the account because there is nowhere else for it to go and no confidence about when the next money arrives.

Access to credit. Large organizations have lines of credit and can borrow against assets. Cash is expensive to hold when you can call on a facility instead. Small organizations rarely have that option, so their buffer has to be cash.

Deployment as a virtue. A large organization holding two years of cash would be criticised for hoarding rather than spending on the mission, and its board would hear about it. Nobody scrutinises a small charity’s balance in the same way.

None of this makes the top row healthy. It means the number has different meanings at different sizes, which is exactly why a single sector-wide rule of thumb misleads in both directions.

What this does and does not mean for you

It does not mean the three to six month target is wrong. A target is a statement about what is prudent, and a distribution is a statement about what is. The two can disagree and both be correct.

What it does mean is that if your organization is under $500k and holding two months of cash, you are not merely below a best practice figure, you are below what comparable organizations actually hold, and that is a much sharper thing to put in front of a board than a benchmark from a consultancy.

It also means the reverse. If you are a small organization sitting on a year of cash and someone has told you that is excessive, the median organization your size holds sixteen months. The question worth asking is whether the money is doing anything, not whether the ratio looks unusual.

Working out your own number

Take cash and savings from your balance sheet, which is the statement of financial position, and divide by your total annual expenses divided by twelve. Both figures are on the financial statements, and if you are budgeting forward rather than looking back, the expense line is in the budget.

Two cautions. Exclude anything donor restricted, because you cannot spend it on general operations and including it flatters the answer. And if your funding is reimbursement based, the number understates you, since money already earned and not yet received sits in receivables rather than cash.

For comparison against other organizations rather than against a benchmark, any nonprofit’s Form 990 is public and carries the same two lines, so the calculation can be run on a peer, a partner, or a prospective employer. Form 990 explains where to find them.

Limits worth stating

This is full Form 990 filers only. It has to be, because the 990-EZ and the 990-N do not carry a full balance sheet. So the smallest band here is not small nonprofits in general. It is organizations with low expenses that file a full return anyway, which is an unusual group, and the 16.4 month median should not be read as typical of the sector’s smallest organizations. Most American nonprofits are not in this dataset at all.

Receivables are excluded from both measures. Organizations funded in arrears look worse here than they are.

It is a snapshot at fiscal year end. Many organizations time their year end for when cash is highest, which biases the whole distribution upward.

The extract is processing year, not fiscal year. Returns processed in 2024 cover a spread of fiscal years, mostly 2022 and 2023.

Reproducing this

The IRS file is a free download and the script that produces every figure above is published with this site rather than described. Anyone can re-run it, change the bands, or disagree with the definition and recalculate. Sector benchmarks are usually quoted without either the data or the method, which is how a number survives for a decade after it stops being true.

The numbers this sits alongside are in fundraising metrics for what else is worth measuring, sector statistics for giving totals, and nonprofit audit for the liquidity disclosure an auditor will ask for.

Questions people ask

How many months of cash does the average nonprofit have?

The median 501(c)(3) filing a full Form 990 holds five months of cash. Medians are the right measure here rather than averages, because the distribution has a very long tail and the mean describes nobody. The figure also varies enormously by size, from 16.4 months for the smallest filers to 1.5 months for organizations spending over $25m.

Is three to six months of reserves still the right target?

As a target, it is defensible. As a description of what organizations hold, it is wrong in both directions: 35.7% of filers are below three months, while the median organization under $100k holds more than sixteen. A target says what is prudent and a distribution says what is, and the two disagree here.

Why do larger nonprofits hold less cash than smaller ones?

More predictable revenue, access to lines of credit, and pressure to deploy money on the mission rather than hold it. A large organization can forecast income months ahead and borrow against assets, so cash is expensive to hold. A small organization with lumpy income has no alternative buffer.

Does this include endowments and investments?

The headline figures do not. They count only cash and savings or temporary cash investments, which is what an organization can spend this month. A second measure adding securities and other investments is reported alongside, and the pattern holds on both. The broad measure overstates availability because it includes endowment principal, which cannot lawfully be spent.

Where does this data come from?

The IRS Statistics of Income annual extract of tax-exempt organization financial data, Form 990, processing year 2024. It is a free public download containing 345,365 returns, of which 259,062 met the criteria used here. It is not a survey or a sample.

Does this cover small nonprofits?

Not really, and this is the most important limit. Only full Form 990 filers have a balance sheet, so organizations filing the 990-EZ or the 990-N are absent. The smallest band is organizations with low expenses that file a full return anyway, which is an unusual group rather than a representative one.

How do I calculate months of cash for my own organization?

Divide cash and savings on your statement of financial position by your total annual expenses divided by twelve. Exclude donor restricted amounts, because they cannot be spent on general operations. If you are funded by reimbursement, note that money earned and not yet received sits in receivables and is not counted.

Can I check another organization's months of cash?

Yes. Every nonprofit's Form 990 is public and Part X carries both cash and total expenses, so the same calculation runs on any filer. It is a reasonable thing to check on a prospective partner, a merger candidate, or an employer.
