Cash Flow and Liquidity

📖 Reading· ~10 min

Why cash flow matters more than a surplus, how to read liquidity warning signs, and what a healthy operating reserve looks like.

Key Takeaways

✓A surplus on the income statement does not mean you have cash — recognize the difference.
✓Maintain 3–6 months of operating expenses as an unrestricted reserve.
✓Restricted cash is not free cash — always confirm unrestricted balances.
✓Late payroll taxes are a serious compliance violation requiring immediate board attention.

Cash flow vs. surplus

A nonprofit can show a surplus on the income statement while simultaneously running out of cash. This happens when revenue is recognized before cash arrives — for example, a pledge that has been booked as revenue but not yet collected. The Statement of Cash Flows shows the actual movement of money in and out of the organization, regardless of when revenue and expense are recognized.

Operating reserves: how much is enough?

Most financial advisors recommend nonprofits maintain an operating reserve equal to 3–6 months of total operating expenses. This gives the organization a cushion to weather revenue gaps, unexpected costs, or a slow grant payment. The board should adopt a formal operating reserve policy that defines the target amount, how the reserve can be used, and how it will be replenished.

Restricted cash is not free cash

A large cash balance can be misleading if most of it is restricted. Restricted funds may only be used for their designated purpose — spending them on operations without donor permission can expose the organization to legal liability. Always ask your finance staff how much of the cash balance is available without restriction.
