How to build a 2027 budget for a small business, step by step

A useful budget for a small business does not need a finance team or a week of meetings. It needs last year's real numbers, a clear split between what repeats and what does not, and an honest guess at what will come in. With those, you can set your 2027 numbers in an afternoon.

This guide walks through that afternoon step by step, with an example budget for a small agency. It works with a spreadsheet and nothing else. The method is the same whether you run a two-person studio, a solo consultancy or a small SaaS.

What do I need before I start?

Three things, all of which you probably already have:

• The last 12 months of bank and card statements for every account the business uses, as PDF or CSV.
• Your list of clients and retainers, with what they pay and how often.
• A spreadsheet, or a sheet of paper if you prefer.

Block two to three hours. Most of the time goes into the first two steps; the rest is quick once the numbers are in front of you.

How do I build a 2027 budget in one afternoon?

Why separate recurring costs from one-off ones?

Because they behave differently next year. A one-off laptop purchase in March 2026 says little about March 2027. A $15-a-seat Figma plan with four seats almost certainly comes back, and probably at the same price or higher.

Recurring costs are your baseline: the money that leaves before you decide anything. They are also where small savings compound. Cancelling one $45-a-month tool nobody uses is $540 a year, every year. If your recurring list has not been reviewed in a while, a SaaS subscription audit before you set the budget usually pays for the time.

For teams, it helps to put a name next to each recurring cost while you have the list open. When someone owns a tool, someone notices when its price changes. SaaS ownership for small teams covers how to split that up.

How do I plan for annual renewals?

List them by month, then decide how to handle the heavy months. A small agency's list might look like this:

• January: domain renewals, about $140
• March: accounting software, yearly plan, $420
• June: project management tool, yearly plan, $960
• September: Webflow site plans, $468
• November: Adobe Creative Cloud, team plan, $1,080
• December: SEO tool, yearly plan, $990

Once they are on a calendar, you have two simple options. Set aside a fixed amount each month (here, about $4,060 a year, so roughly $340 a month) so the money is ready when the renewal lands. Or, for the larger ones, check whether monthly billing is available and whether the higher total is worth the smoother cash flow.

How should I plan money in?

Conservatively. A budget that only works if every deal closes is a wish list.

A simple way to split it:

• Signed and recurring: retainers and subscriptions with a contract or a long track record. Count them in full, in the month they usually arrive.
• Likely: repeat clients and projects in late discussion. Count them at a discount, for example half, or push them a month later than you expect.
• Possible: everything in the pipeline that is not yet likely. Leave it out of the budget and treat it as upside.

If you have clients who regularly pay late, plan their money for when it usually arrives. For more on tracking retainers and late payments, see how to track recurring revenue.

What does a simple small-business budget look like?

Here is a monthly budget for a small agency, built from its 2026 statements. The left column is the 2026 monthly average; the right is the 2027 plan.

On the money-in side, the same agency has three signed retainers worth $7,200 a month and averages about $3,000 a month in projects. Counting projects at half gives $8,700 a month of planned income against $8,070 of planned spending. That is thin, but it is honest, and every project above the plan improves the year.

How do I keep the budget on track during the year?

Look at it once a month, for about 20 minutes. Compare each category's budget with what you actually spent, and write one line on why the biggest gaps happened. Then decide whether the budget or the spending needs to change.

The monthly look is also when you catch quiet changes: a tool that went up 20%, a new seat someone added, a client who started paying later than usual. Small things are cheap to fix in February and expensive to discover in December.

A budget tells you how much; it does not tell you when. If your money in arrives in lumps, pair the budget with a short cash forecast. The practical guide to cash flow shows how to build a 13-week one by hand.

Is a spreadsheet enough for a small-business budget?

For many small businesses, yes. The method above works on a single sheet, and if you prefer to keep your recurring costs there too, the subscription tracker spreadsheet is a good companion.

Where a spreadsheet gets tiring is keeping it current: re-reading statements each month, noticing price changes and remembering to check the budget before it is already crossed. If that is where your time goes, an app that reads the statements and tells you when a budget gets close can take over the routine part, and leave you the decisions.
