Business Calculators

Tools for freelancers, consultants, and small business owners. Figure out what to charge, price your work, and run the numbers on self-employment.

Working for yourself means you're also your own accountant, pricing strategist, and operations team. These calculators help you make better decisions on the money side — without sign-ups, paywalls, or selling your data.

Every tool runs entirely in your browser. Nothing you enter is stored or sent anywhere.

Freelancers and small business owners face money decisions employees never think about: what hourly rate actually covers your taxes and unpaid time, how to price a project so it's profitable, and how much to set aside for self-employment tax. Guessing at these numbers is where a lot of independent workers quietly lose income. The calculators here turn each of those questions into a concrete figure in a few seconds.

If you're just starting out, a good sequence is to work out your target hourly or day rate first, then use the profit-margin and markup tools to price individual jobs, and finally sanity-check the year with a self-employment tax estimate. Each calculator explains the formula behind it, so you can see exactly how the number is built rather than trusting a black box.
