Three to six months is a common rule of thumb (see the Nonprofit Finance Fund and the National Council of Nonprofits); organizations with lumpy or grant-reliant revenue may target more. A formal, board-adopted reserve policy is what funders look for.
Unrestricted income is what fills a reserve
You can only build a reserve from unrestricted surplus — the hardest money to raise. Good Circles creates a recurring, unrestricted stream from a share of supporters’ everyday local spending (about 10% of each merchant’s net profit; conservatively ~$72 per active supporter per year, an estimate), free for your nonprofit — exactly the kind of money that lets a reserve grow.

FAQ
How many months of operating reserve should a nonprofit have?
A widely cited benchmark is three to six months of operating expenses. Organizations with volatile or grant-dependent revenue often aim higher, while those with very stable revenue may hold less. The right level is a board decision based on your risk.
What counts as an operating reserve?
An operating reserve is unrestricted net assets held in liquid form (cash or readily sold investments) that the board has designated to cover a shortfall or emergency. Donor-restricted funds and illiquid assets do not count.
How do I calculate months of reserve?
Divide your reserve balance by your average monthly operating expenses, which is annual expenses divided by twelve. A reserve of $150,000 against a $600,000 budget covers three months.
Do funders care about reserves?
Yes. A healthy reserve and a board-adopted reserve policy signal financial stability, which funders and auditors view favorably. Some grant applications ask directly about your reserves.
