How to Create a Startup Budget (Step by Step)

A startup budget is your financial map. It tells you what you can spend, when you'll run out of cash, and where to cut if needed. Here's how to build one.

Categories to Include

**One-time costs** — Equipment, legal setup, incorporation, logo/design, initial inventory. These hit once at the start.

**Monthly costs** — Software (tools, hosting), marketing (ads, content), contractors, rent, utilities. Recurring.

**Variable costs** — Scale with usage: payment processing, shipping, COGS. Estimate based on projected volume.

Buffer for Surprises

**Add 20–30% for surprises.** Things cost more than you expect. Timelines slip. Revenue is slower. A buffer gives you runway when reality hits.

Often Forgotten Items

• **Taxes** — Set aside 25–30% of profit for income tax. Or use a separate account.
• **Payment processing fees** — 2.9% + 30¢ per transaction adds up. Include in your model.
• **Domain, hosting, tools** — Small but recurring. $50–200/month is common for a lean startup.
• **Insurance** — Liability, professional, or cyber. Often required for contracts.

Tools to Use

**Spreadsheet** — Simple. Free. Flexible. Google Sheets or Excel. One tab for one-time, one for monthly.

**Causal, Notion, or specialized tools** — When you need more sophistication. Start with a spreadsheet; upgrade when you outgrow it.

Review Monthly

Compare actuals to budget. Where are you over? Under? Adjust. A budget is a living document. Update it as you learn.
