About Self Employed Calculator
Self Employed Calculator is a free toolkit for freelancers, independent contractors, and consultants. It provides 23 calculators covering every financial decision in the freelance lifecycle — from setting your first rate to planning for retirement on irregular income.
Why We Built This
Most freelancers undercharge — not because they lack skill, but because calculating a fair rate is surprisingly complicated. You have to account for taxes (which are higher as a freelancer), paid vacation you're effectively giving up, overhead costs, and the profit margin that keeps your business healthy. Without the right tools, most people guess.
Self Employed Calculator makes these calculations instant and shareable. Every tool runs in your browser with no data sent anywhere. You can pre-fill inputs and share the URL with a client, accountant, or fellow freelancer. It's the toolkit we wished existed when we started freelancing.

Your income, tax rates, and financial data never leave your device. All calculations run entirely in your browser. We store nothing.
Built for Freelancers
Every tool is designed around real freelance decisions — setting a day rate, estimating quarterly taxes, calculating whether a client is profitable.
Always Free
Every tool is free with no account required. We are funded through advertising and affiliate partnerships with invoicing and payment tools.
