Cash flow and reserves.

How much cash should you have?.

The right answer depends on revenue concentration and predictability. A nonprofit with diverse, recurring individual giving can run on less cash than one dependent on three multi-year grants. As a starting framework:

• Less than 1 month: material risk. Payroll could fail.
• 1–3 months: stressed. Most decisions are short-term defensive.
• 3–6 months: functional. Routine operations are safe.
• 6–12 months: strong. Strategic moves become possible.
• 12+ months: watch for under-investment in mission.

Weekly visibility into cash position for the next quarter. Updated weekly. Shows when grants will hit, when reimbursements will arrive, when payroll cycles, when large vendor payments are due. Identifies crunch weeks before they happen so you can move money, accelerate collections, or have hard conversations early.

Building an operating reserves policy.

A board-approved policy that defines target reserves, when reserves can be drawn down, and how they’ll be rebuilt. Without a policy, reserves get spent reactively and rebuilt never.

How much is enough.

The standard guidance — 3 to 6 months of operating reserves — is a starting point, not an answer. The right reserve target depends on:

• Revenue volatility. A nonprofit with stable, multi-year grants needs less reserve than one dependent on annual fundraising.
• Cash flow timing. Government contracts that reimburse 60–120 days after spend require working capital beyond reserves.
• Program continuity risk. What would it cost to wind down responsibly if a major funder pulled out?
• Strategic horizon. Is the organization planning growth, a campaign, or a significant capital investment?

For most stable mid-sized nonprofits, the answer is 4–6 months. For organizations with concentrated funding, more.

Reserve types worth distinguishing.

• Operating reserve. Liquid, accessible, board-designated, used to bridge timing gaps or absorb shocks.
• Working capital. Funds needed for normal cash flow operations (e.g., to cover the gap between government billing and reimbursement). Sometimes separate from operating reserve.
• Opportunity reserve. Funds set aside for strategic investments — new programs, real estate, capital purchases.
• Quasi-endowment. Board-designated funds invested for longer time horizons.

Lumping these into one bucket makes spending decisions harder. Separating them clarifies what cash is for what purpose.

How to build reserves without slowing the mission.

Reserves are built by intent, not accident. A few approaches that work:

• Build a reserve line into the annual operating budget (e.g., 2–3% of revenue).
• Allocate a percentage of unrestricted gifts above $10K directly to reserves.
• Run an annual or biennial reserve campaign with the board.
• Treat the year-end surplus as reserve-bound by default, not available for next year’s budget.

Questions boards ask.

Is it irresponsible to hold large reserves? No, but it is irresponsible not to spend on the mission. Reserves that exceed clearly articulated needs invite legitimate scrutiny. Reserves built with a published policy and a strategic purpose are defensible.

Can we use restricted gifts to bridge short-term cash gaps? No. Restricted funds are restricted — using them as working capital exposes the organization legally and reputationally. Working capital is unrestricted.

What about a line of credit? A line of credit is a useful complement to reserves, not a substitute. It can bridge timing gaps cheaply. It does not replace the cushion against unexpected loss of funding.
