Create a realistic first-year business budget with monthly projections and contingency planning.

A realistic first-year business budget is a twelve-row monthly model, not an annual total. It states a revenue ramp you can defend with an assumption, separates fixed costs that arrive whether or not you sell from variable costs that scale with volume, and reserves cash for tax on profit you have not yet taken out. Most first-year budgets fail because they annualise: they assume the average month twelve times instead of the actual shape of the year.
Every credible budget rests on one sentence: how a customer finds you and how many will in month one. Write that sentence, then derive the ramp from it. A ramp of 5, 9, 14, 20, 27 customers is defensible if you can name the channel producing them; a flat 25 per month from day one is not.
Two structural facts shape the shape of the year. Cash arrives after the sale, typically 30 days later for business customers, and marketing spend leads revenue by one to three months. Both push the cash trough later than founders expect, usually into months four through eight.
| Quarter | Revenue as % of year total | Spending focus | Cash position |
|---|---|---|---|
| Q1 | 5 - 10% | Setup, first marketing tests, hiring nobody | Steepest decline |
| Q2 | 15 - 20% | Double down on the one channel that worked | Trough, often the low point |
| Q3 | 25 - 30% | First hire or contractor capacity | Flattening |
| Q4 | 40 - 50% | Reinvest from gross profit, not from reserve | Improving, possibly break-even |
Fixed costs set your break-even and your risk; variable costs set your margin. Keeping them in separate blocks means you can answer the only two questions that matter mid-year: what happens if revenue is half the plan, and what happens if it is double.
Month four is the trough, not month one (2026)
Fixed monthly costs .................... $ 9,400 Gross margin on sales .................. 62% Month 1: revenue $4,000 -> GP $2,480 Net cash movement .................... -$6,920 Month 2: revenue $7,000 -> GP $4,340 Net cash movement .................... -$5,060 Month 3: revenue $10,500 -> GP $6,510 Net cash movement .................... -$2,890 Month 4: revenue $12,000, but $8,000 unpaid Cash GP received ..................... $ 2,480 Net cash movement .................... -$6,920 Cumulative cash used by month 4 ........ -$21,790 Break-even revenue = $9,400 / 0.62 ..... $15,161
