Frequently Asked Questions

How much money do I need to start a business?

It depends entirely on your one-time launch costs (incorporation, domain, branding, initial software) plus your monthly recurring costs (hosting, tools, contractors) multiplied by how many months you need to cover before you're profitable or raise more money.

Is this startup cost calculator free?

Yes — completely free with no signup required. Enter three numbers and get an instant breakdown.

Why does the calculator add a 20% buffer?

Nearly every first-time founder underestimates costs — legal surprises, tool overages, or a launch that takes longer than planned. A 20% buffer is a common rule of thumb to avoid running out of cash right when you need it most.

What's the difference between this and the Runway Calculator?

This calculator estimates how much you need before you launch. Our free Runway & Burn Rate Calculator estimates how many months you have left once you already have cash in the bank and know your actual expenses and revenue.

What should I do before spending this money?

Before you commit real cash to launching, validate that the problem you're solving is one people actually complain about. Our free Idea Validator checks your idea against live complaints from Reddit, Hacker News, and Indie Hackers.
