You have no real budget, or you have one that the board approved and nobody has looked at since. So you fly the year blind, find out in month ten that something drifted, and have no way to tell a good surprise from a bad one until it has already happened.
This guide turns your mission and plan into a budget that means something, gets it properly adopted, and builds the monthly habit of checking it against what actually happened, so surprises get caught in month two instead of month ten. It is the work of planning your year in numbers and then steering by them. It is not a wish list, and it is not a document you build to satisfy a funder and then file. A budget that does not change a single decision is not a budget, it is a decoration. It is also not the same as seeing where you stand; that is the previous guide, and this one assumes your books are current enough to compare against. Use this if you have no budget, or a budget that steers nothing. If you already check a live budget against reality every month and your trouble is really the timing of cash or the tangle of restrictions, go to Manage Cash Flow or Master Restricted and Unrestricted Funds.
A budget is only as honest as the assumptions under it. For each source of money, write what you realistically expect and the reason, grounded in last year and what has actually changed, not in hope, and mark which income is committed and which is only likely. Then, from your direction and priorities, name what the year must fund.
Open the Budget Assumptions Worksheet →Turn the assumptions into a full-year budget that balances, or that shows honestly where it does not. Lay out expected income and planned spending across the year, by program or function, specific enough to steer, then test the draft against last year's actuals and your cash reality: can you actually afford the timing of this, not just the annual total.
If honest revenue does not cover what the priorities require, do not paper the gap with a hopeful number. Name the gap plainly and route it: to the funding work if the answer is more revenue, to your priorities if the answer is doing less, and, if the gap will not close either way, to the deficit question and to mission clarity and strategic direction for whether all of this work belongs in your organization. A budget built on a number you invented to make it balance is worse than no budget. This is a route, not a stop.
A budget becomes the organization's plan when the board formally adopts it. Until then it is a proposal. Present the budget and its key assumptions, answer the board's questions, adopt it by formal action, and record it in the minutes so it is the reference for the year.
Open the Budget Adoption Checklist →A budget adopted and shelved steers nothing. Each month, put the budget next to the actuals, find the meaningful gaps, and for each ask whether it is timing, a one-time event, or a real trend. Decide what each real variance calls for, and update your view of where the year will land. The whole value is in catching a trend in month two instead of discovering it at year end.
Open the Budget-versus-Actual Review →If building the budget surfaces that you genuinely cannot cover your costs no matter how you cut it, that is not a budgeting failure, it is a strategic question, and it belongs with your board and, likely, an accountant who can confirm the numbers. And if the budget work runs into a tax or filing obligation you have missed, that goes to a nonprofit accountant. The guide steers the money you have; it does not decide the organization's future or keep it legal, and it will tell you when you have reached those edges.
You have a budget your board adopted this year. You compare it to reality every month, not once. And when a number drifts, you now catch it in month two and do something, instead of discovering it at year end.
Most leaders move from here to Manage Cash Flow, because a sound annual plan still has to survive the timing of money month to month. Your budget must respect the split between free and spoken-for money, which is Master Restricted and Unrestricted Funds, and the cushion is Build Financial Resilience and Reserves. If you came in through a crisis and have steadied, the whole-organization check-up is the honest next look once this is done.
