The Cash Flow Problem

Nonprofits have uneven revenue: grants arrive in chunks ($50k in month 3, nothing for 2 months), donations spike at year-end, events generate lump sums. But expenses are constant (payroll, rent, utilities every month).

This mismatch causes cash flow problems: months where revenue is zero but expenses are $50k. You need cash reserves to bridge gaps.

Monthly Cash Flow Forecasting

Build a 12-month cash flow projection:

  • Column A: Month
  • Column B: Beginning cash balance
  • Column C: Projected revenue (grants, donations, earned revenue, events)
  • Column D: Projected expenses (payroll, rent, supplies, program costs)
  • Column E: Net (C-D)
  • Column F: Ending cash balance (B+E)

Example 12-month forecast:

Month Revenue Expenses Net Ending Cash
Jan$10k$50k-$40k$60k
Feb$5k$50k-$45k$15k
Mar$75k$50k+$25k$40k

This forecast shows January and February will have cash flow problems. March recovers. You need $40k+ in reserves to handle January shortfall.

Solutions to Cash Flow Problems

Solution 1: Line of Credit** Establish credit line with bank ($25k-50k depending on org size). Use only when revenue timing gap creates shortfall. Pay interest but not as expensive as overdraft fees. Recommended: establish line before you need it.

Solution 2: Operating Reserve** Set aside 3-6 months expenses in savings account. This is your emergency fund for months with shortfalls. See Building an Operating Reserve.

Solution 3: Expense Timing** Delay some expenses until cash arrives. Pay some vendors after receiving payment from major grant. (Not ideal—vendors prefer on-time payment—but sometimes necessary.)

Solution 4: Diversify Revenue Timing** If all grants come in March, create other revenue sources with different timing: monthly donors (revenue every month), earned revenue (revenue ongoing), events (revenue upfront). Less dependence on chunk payments.

Building Cash Reserves

Conservative approach:**

  • Year 1: Build $10k reserve (1 month of expenses)
  • Year 2: Build to $30k (2 months)
  • Year 3+: Target $50k-100k (3-6 months)

How to build reserves:**

  • Underspend budget modestly and keep surplus in reserve
  • Reserve incoming major gifts/grant windfalls for reserves (don't spend every dollar)
  • When month is profitable (revenue > expenses), put surplus in reserve account

Reserve account characteristics:**

  • High-yield savings account (4-5% interest currently)
  • Separate from checking account (prevents accidental spending)
  • Policy: only use for genuine cash flow emergencies, not program expansion
  • Goal: replenish within 6-12 months of use

Communicating Cash Flow Concerns

If cash flow is tight, be transparent with board:

  • "We'll have cash shortfall in Feb-March. Our forecast shows we'll need $40k from line of credit unless Q1 grants arrive early."
  • "We're building reserves. This year we're allocating $5k surplus to reserves."
  • "We need donors to consider monthly giving to smooth out annual lumpiness."

Honesty prevents panic and helps board help you solve problems.

Frequently Asked Questions

Is a line of credit expensive?

Marginally. If you draw $40k at 8% for 2 months, cost is ~$533. Compare to overdraft fees ($35-50 per overdraft, multiple per month). Line of credit is cheaper. Establish it before you need it.

How much cash reserve do we really need?

Minimum: 1 month expenses. Ideal: 3-6 months. Orgs with uneven revenue (heavy Q4 giving) need 6 months. Orgs with steady revenue can do 3 months. Calculate your org's expenses per month and build accordingly.

Is it okay to use reserves for normal operations?

No. Reserves are for emergencies (major funder exits, unexpected expenses). If using reserves regularly, you have structural budget problem that needs fixing, not just cash management. Address root cause.
