How to Build a Nonprofit Budget: A Step-by-Step Process for Finance Staff

Published: Last updated: Reviewed:

TLDR

Building a nonprofit budget requires layering four things in sequence: confirmed funding with restriction terms, personnel costs including fringe, program-level cost allocation, and indirect cost recovery — organizations that build in the wrong order produce budgets that look balanced but collapse when a grant isn't renewed. The sequence matters because each layer constrains the next.

The nonprofit budget process has a sequencing problem that most finance staff encounter by accident: you cannot build a program budget before you know what the personnel costs are, and you cannot know what the personnel costs are before you know the funding mix, because the funding mix determines which grant pays for which position. Build in the wrong order and you will spend a week rebuilding the budget from scratch when a grant renewal comes back at a lower amount.

When to run this workflow

Run this workflow once per fiscal year, 90 days before the fiscal year begins. Also run a mid-year budget revision if actual revenue or expenses have deviated from budget by more than 10% and the deviation is expected to continue. A budget revision is not a sign of poor planning — it is a sign that the organization is paying attention.

Common pitfalls

Budgeting revenue optimistically and expenses accurately. Finance staff tend to be conservative with expenses and optimistic with revenue, which produces budgets that look balanced and run deficits. Apply the same skepticism to revenue assumptions that you apply to expense estimates.

Mixing restricted and unrestricted funds in the consolidated view. A budget that shows total revenue and total expenses without separating restricted and unrestricted funds can appear balanced while the unrestricted fund is running a structural deficit covered by restricted revenue. Restricted and unrestricted funds must be reported separately to show the real financial picture.

Omitting indirect cost recovery from grant budgets. Every grant that allows indirect cost recovery should have it built into the budget. An organization that undercharges indirect recovery is subsidizing its restricted programs with unrestricted funds and reducing its capacity to cover overhead.

Building a single-scenario budget. A budget with no scenario analysis gives the board no ability to manage risk. The three-scenario model is a minimum; organizations with significant revenue uncertainty should add a fourth scenario showing a major-funder-loss event.

Frequently asked

Frequently Asked Questions

When should we start the budget process?
Start 90 days before the fiscal year begins. A September 1 fiscal year requires a budget process that begins in June: grant data collection in June, personnel budget in July, program and consolidated budget in August, board approval in late August or early September. Starting later compresses the process, produces shortcuts, and often results in a budget approved after the fiscal year has already started.
What fringe rate should we use if we don't have a pooled rate?
Calculate your actual fringe rate: total benefits paid in the prior year divided by total salaries paid. For most nonprofits this falls between 18% and 30%. Apply this rate uniformly to all positions in the budget. If your benefits structure varies significantly by employee (full-time vs. part-time, exempt vs. non-exempt), build actual benefits per employee rather than using a pooled rate. Document whichever method you use.
How do we budget for a grant we expect to win but haven't received yet?
Include pending grants at no more than 50% of the expected award, and only if you have submitted a proposal or been invited to apply. Do not budget for grants you plan to apply for but have not yet applied to. The conservative scenario should show the budget without the pending grant so the board can see the downside. If the pending grant is essential to a balanced budget, that is a structural risk the board needs to understand before approving.
What is the right level of operating reserve?
The standard guidance is three to six months of operating expenses in unrestricted liquid reserves. Organizations with highly variable revenue (heavy grant dependence, single major funder) should target six months. The board adopts a formal reserve policy stating the target range and the conditions under which reserve can be drawn. Once the reserve policy exists, every budget approval includes a check against it.
Can restricted funds show a surplus?
Temporarily restricted funds can carry a surplus from one year to the next if the restriction has not yet been satisfied — this is normal when a multi-year grant spans budget years. What you cannot do is use a restricted fund surplus to cover an unrestricted deficit; those funds must be spent in accordance with the restriction. If a restricted fund shows a large surplus and the grant period is ending, you have an unspent balance problem that needs to be resolved with the funder.
