Financial ratios for nonprofits connect available cash, funding concentration and functional expenses. Work through two reporting years and see why a stronger surplus can accompany weaker cash coverage.
Financial ratios for nonprofits show whether an organization has usable financial capacity to sustain its mission. Start with available cash coverage, dependence on major funders, functional expense shares and the operating result. Read them together: reported cash and surplus can rise while the resources available for ordinary bills fall.
The general financial ratios guide explains commercial liquidity and profitability formulas. For a nonprofit, the first additional question is whether the resources in the numerator can support the expenses in the denominator.
Use these definitions consistently in the management report:
Routine-use cash coverage, months = Cash available for routine general expenditures / (Annual cash operating expense proxy / 12)
Funded designated-reserve coverage, months = Board-designated emergency cash / The same monthly expense proxy
Largest-funder concentration = Revenue from the largest individual funding source / Total revenue
Program expense ratio = Program expenses / Total functional expenses
Operating surplus ratio = (Operating revenue − Operating expenses) / Operating revenue
These are management measures with stated boundaries. The cash measure below excludes a board-designated emergency reserve until the board authorizes its use. It therefore measures routine availability, rather than all emergency resources the organization could access.
The FASB update on nonprofit financial statements distinguishes net assets with and without donor restrictions and explains that resource availability can be limited by external restrictions or board decisions. Net assets without donor restrictions are not synonymous with cash: they can include buildings and other resources that cannot fund next week's bills.
Use a closed ledger, a functional expense report, a funding register and a cash restriction schedule for the same reporting date. The funding register needs a stable funder identifier, recognized revenue, collection dates and restriction information. Aggregate awards from the same funder before ranking sources.
For expenses, keep both natural accounts, such as payroll and rent, and functional assignments. The IRS Form 990 instructions for Part IX distinguish program services, management and general, and fundraising expenses, and require documented allocation methods. A management report should retain a bridge to those categories even when its operating scope differs from the return.
An illustrative Ohio community services nonprofit has the following export summaries. Each column covers a full fiscal year ended September 30. All revenue and expenses shown are operating items; there are no investment gains, capital gifts or other nonoperating items in this example.
| Export line (USD) | Fiscal 2025 | Fiscal 2026 |
|---|---|---|
| Largest individual funder revenue | 750,000 | 1,080,000 |
| Other grant revenue | 450,000 | 420,000 |
| Individual contributions | 600,000 | 650,000 |
| Program service fees | 500,000 | 550,000 |
| Program expenses | 1,680,000 | 1,920,000 |
| Management and general expenses | 240,000 | 300,000 |
| Fundraising expenses | 180,000 | 180,000 |
| Depreciation included in expenses above | 60,000 | 60,000 |
| Closing cash and cash equivalents | 600,000 | 650,000 |
| Cash unavailable for general use under donor restrictions | 180,000 | 300,000 |
| Separate board-designated emergency cash | 60,000 | 80,000 |
The two cash exclusions are separate balances; neither contains the other. For this illustration, depreciation is the only noncash expense. Subtracting it produces an expense proxy, not actual cash payments: payable movements, debt principal and capital spending would require a separate cash schedule.
Sum the revenue categories, then the functional expenses. Keep full precision in calculations; display percentages to one decimal place and coverage to two decimal places.
| Calculation | Fiscal 2025 result | Fiscal 2026 result |
|---|---|---|
| Total revenue: sum of funding rows (USD) | 2,300,000 | 2,700,000 |
| Total expenses: program + management + fundraising (USD) | 2,100,000 | 2,400,000 |
| Operating surplus: revenue − expenses (USD) | 200,000 | 300,000 |
| Operating surplus / revenue | 8.7% | 11.1% |
| Cash expense proxy: expenses − depreciation (USD) | 2,040,000 | 2,340,000 |
| Monthly proxy: cash expense proxy / 12 (USD) | 170,000 | 195,000 |
| Routine-use cash: cash − restricted cash − board reserve (USD) | 360,000 | 270,000 |
| Routine-use cash / monthly proxy | 2.12 months | 1.38 months |
| Funded board reserve / monthly proxy | 0.35 months | 0.41 months |
| Largest funder / total revenue | 32.6% | 40.0% |
| Program expenses / total expenses | 80.0% | 80.0% |
| Management and general / total expenses | 11.4% | 12.5% |
| Fundraising / total expenses | 8.6% | 7.5% |
For fiscal 2026, the cash check is $270,000 + $300,000 + $80,000 = $650,000. The expense check is $1,920,000 + $300,000 + $180,000 = $2,400,000. Functional shares sum to 100.0% in each year; calculate from unrounded amounts if displayed shares leave a rounding difference.
Cash rises by $50,000, but routine-use cash falls by $90,000. That is why the bank balance alone gives the wrong impression of ordinary spending capacity. The unchanged program expense ratio also conceals the fall in coverage and the greater dependence on one funder.
The funded board reserve covers 0.41 months of the expense proxy in fiscal 2026, compared with 0.35 months previously. That reserve is a separate layer of protection requiring authorization. A larger designation alone would not prove greater protection unless the cash backing it existed.
For the wider reporting pack, select complementary financial KPIs rather than adding several ratios that express the same funding risk.
The finance director owns the ledger ties, definitions and availability bridge. Development staff own renewal dates and funder relationships. Program leaders explain cost commitments, while the board owns reserve access and replenishment decisions. Ratio reporting becomes useful when each movement leads to a specific review.
Consider a sensitivity applied to the fiscal 2026 figures, with expenses unchanged:
| Sensitivity step | Calculation | Result (USD) |
|---|---|---|
| Assumed reduction in largest funder | 1,080,000 × 25% | 270,000 |
| Revised revenue | 2,700,000 − 270,000 | 2,430,000 |
| Revised surplus | 2,430,000 − 2,400,000 | 30,000 |
The revised surplus ratio is $30,000 / $2,430,000 = 1.2%, rounded. This is an explicit assumption, not a prediction. It identifies a renewal conversation and contingency review; it does not establish when cash will run out. Use a dated cash flow forecast for that question.
Broader nonprofit financial analysis can connect the ratios with program commitments and funding conditions without treating a single percentage as a performance verdict.

Set the reserve target from revenue volatility, reimbursement delays, fixed commitments and access to financing. The board should document when reserves may be used and replenished. Compare the target with resources actually available under that policy rather than copying another organization's ratio.
Only when those expenses meet the donor's applicable restrictions. Cash held for a future purpose is not automatically available for current payroll. Keep a restriction schedule by award and reconcile it with the ledger before including cash in a general operating coverage measure.
A higher ratio means more reported expense is assigned to programs under the allocation policy used. It does not measure service quality or financial resilience. Review outcomes, necessary administration and allocation consistency alongside the ratio before treating a change as an improvement.
Use recognized revenue for a revenue concentration measure and receipts for a cash dependency measure. Label each clearly. A multiyear award recognized before collection can dominate revenue concentration while the organization's current cash depends on a different mix of funders.
