Building and updating a nonprofit budget
Updated 16 October 2026
A nonprofit budget states in dollars what the organization plans to do for the year. It names the programs, the people served, the cost of the work and the sources that pay for it. A budget that no one opens after January stops guiding anything. A budget that staff own, review each month and update each quarter keeps guiding decisions all year. This page covers how to build one, how to compare it with results and how to update it. The worked examples use round figures as an illustration.
Start from the program plan
The budget starts with the programs the organization will run this year. Last year's profit and loss is a reference, and the program plan comes first. Five steps follow.
- Write down the program plan for the year.
- Estimate revenue by source, with caution. Sources include grants, individual gifts, events, earned revenue and government contracts. Each grant still under review is weighted by its likelihood of arriving.
- Tie each staff position to the program it serves. A position linked to a named result is simpler to defend and simpler to fund.
- Budget indirect costs, also called overhead, at the rate the organization actually incurs. The rate a funder prefers to see is a separate number.
- Turn the revenue plan into a cash plan. Revenue and cash arrive at different times, and reimbursement grants widen the gap.
Three grant requests are pending. Grant A asks for $200,000 and is rated 90% likely, so the budget carries $180,000. Grant B asks for $150,000 at 50%, so the budget carries $75,000. Grant C asks for $100,000 at 25%, so the budget carries $25,000. The requests total $450,000, and the budget carries $280,000, which is $170,000 less than the full ask. The figures are an illustration.
Build it by program and then add it up
Many nonprofits build the budget in a spreadsheet, one expense line at a time: salaries, rent, supplies and outside services. That layout helps with tracking. It says little about which work the money pays for. A budget built program by program shows what each program costs, what it delivers and what income it brings. The program budgets then add up to the organization's total. The result shows which programs pay their own way, which ones the organization supports from general funds, and how growth or cuts in one program move the total.
A youth program costs $520,000 and brings $400,000 of dedicated income, a gap of $120,000. An adult program costs $280,000 and brings $300,000, a surplus of $20,000. A family program costs $250,000 and brings $150,000, a gap of $100,000. Across the three, costs are $1,050,000 and dedicated income is $850,000. The organization needs $200,000 of unrestricted money to run all three. The figures are an illustration.
Revenue timing and cash timing
A budget shows revenue in the month it is earned. The bank sees cash in the month it arrives. A reimbursement grant pays only after the organization has spent the money and billed the funder, so the organization carries the cost until payment arrives. The cash plan shows that carrying cost month by month.
A $240,000 reimbursement grant funds a program that spends $20,000 a month. The funder pays each bill 60 days after it is sent. At any point after the second month, the organization has $40,000 of program spending waiting for repayment. The budget shows $20,000 of grant revenue each month, and the cash plan shows the $40,000 the organization carries. The figures are an illustration.
Comparing budget with actual results
Budget-to-actual reports exist to show what is changing in time to act. Each line that runs over or under budget has an owner. The owner explains the variance and proposes a response. The board's monthly review compares budget with actual results, and a report of actual figures alone leaves out the plan.
The annual budget is the plan. The forecast is the current estimate of how the year will end. The forecast is updated at least once a quarter. When the plan and the forecast differ, decisions follow the forecast.
The budget plans $2,400,000 of revenue, or $600,000 a quarter. First-quarter revenue comes in at $520,000, which is $80,000 below plan. The reforecast assumes the other three quarters hold to plan and moves the year's revenue estimate to $2,320,000. Leadership then decides in April which $80,000 of spending to defer. The figures are an illustration.
Testing the revenue estimate
The base case uses committed money, expected renewals and the organization's past patterns. A downside case assumes that one large source shrinks. If the downside case still pays for the programs, the base case is reasonable. If it does not, the revenue estimate needs more caution.
Four habits wear a budget down over the year. Inflating revenue to cover planned spending turns the budget into a wish list. Counting restricted gifts as general operating revenue puts money in the totals that cannot pay for operations. Skipping the reforecast after results move away from the plan leaves leadership without a current view. Building the budget once and never updating it makes the figures fiction.
The base case projects $2,000,000 of revenue, of which the largest funder supplies $600,000. The downside case cuts that funder by 30%, which removes $180,000 and leaves $1,820,000. The finance team checks whether $1,820,000 still covers the programs the board approved. The figures are an illustration.
A budget calendar
- Four months before the fiscal year starts, leadership reviews programs, priorities and the funding pipeline.
- Three months before, staff build a draft from the bottom up by program and department.
- One to two months before, the board reviews and approves the budget.
- Each month, the board compares budget with actual results.
- Each quarter, the finance team updates the forecast through year end.
A planned deficit can be a sound choice, for example to spend down a restricted gift or to pay for new capacity. The plan then covers more than one year and shows a return to surplus. A deficit that repeats year after year points to a problem with the strategy, and the accounting cannot fix it.
An organization's fiscal year starts on 1 July. Program review starts in March, four months ahead. The draft is built in April, three months ahead. The board reviews and approves the budget in May or June. Quarterly reforecasts follow in October, January and April. The figures are an illustration.
What this means for a nonprofit
The budget starts from the program plan and is built program by program. Pending grants are weighted by likelihood. Indirect costs are budgeted at the rate the organization incurs. A cash plan sits beside the budget, because reimbursement grants pay after the money is spent. Each variance has an owner, the forecast is updated each quarter, and restricted gifts stay out of operating revenue.

What happens next
Reading about it and having it done are different things. Here is exactly what happens if you want the second one.
- The call takes thirty minutesYou describe the business and where the numbers are letting you down. We give you an expert view of your situation, and what we would start with. There is no pitch deck.
- We look at the fileYou give us read access to the books as they are. We come back with what is wrong, what it will take to fix, and whether the answer is bookkeeping, controller work, or something else.
- We send a written scope and a priceIt lists what we do each month, what you get, the date it lands and the fee. We agree it before anything starts, and it does not change unless you agree.
- We take over the books and close the first monthWe set up access and systems and enter the opening balances. The first close lands on the date in the scope, and every one after it does too.
