Nonprofit reserves: how much cushion is healthy?
Too little reserve is fragility, too much is hoarding. How months-of-reserves works and where the reasonable range lies.

By the numbers — from the CharityIndex dataset
16.2 months
Median operating reserves
The median nonprofit holds 16.2 months of operating reserves, and 83% hold the 3+ months watchdogs consider a healthy cushion — computed from 6,299,177 e-filed Form 990s (CharityIndex).
Reserves are what a nonprofit can fall back on when a grant ends, a recession hits or a roof fails: net assets measured against the pace of spending. The standard yard stick is months of reserves — net assets divided by one month of expenses.
Reading the number
- Under 1 month — living hand to mouth; one bad quarter forces layoffs or cuts.
- 3–6 months — the range most boards and the BBB Wise Giving Alliance treat as prudent.
- 1–5 years — comfortable; common for organizations with lumpy funding or endowment income.
- Beyond ~5 years — fair to ask why donations are still being solicited faster than the mission spends them.
Nuances that change the read
- Restricted funds and endowments inflate net assets but can't pay next month's rent — a large "reserve" may be legally untouchable.
- Negative net assets — owing more than you own — is the loudest alarm a 990 can sound.
CharityIndex computes months-of-reserves on every profile and folds it into the financial-health side of the letter grade — capped at the top so that extreme hoarding reads as stewardship risk, not excellence.
