Why freelancers need money calculators

Freelancers, contractors, and gig workers handle every part of a business alone: pricing, invoicing, and taxes. The most common — and most expensive — mistake is guessing at rates. Underpricing by even a few dollars an hour compounds over a year into thousands of lost income, while setting aside too little for taxes turns every April into a crisis.

Most rate advice online is vague ("charge what you're worth!") or aimed at full-time employees. These free freelance tools use the simple arithmetic that actually answers the questions freelancers ask: what should my hourly rate be, how does a contract rate compare to a salary, how much should I set aside for taxes, and what does my day rate equal per hour?

FAQ

How much should I pay myself each month from my business income?

Pay yourself what is left after the business and the tax office take their shares: monthly revenue minus business expenses, minus the tax set-aside (25–30% of net in the US), minus a one-month buffer — the remainder is your pay. Find your floor with the break-even calculator, enforce the tax share with the set-aside calculator on every invoice, and never pay yourself from gross revenue.

Is there an app that helps freelancers set pay and save for tax?

These calculators are built for exactly that and run entirely in your browser — no install, no account, your numbers never leave your device. Use the tax set-aside calculator on every payment, the break-even calculator for your monthly floor, and the quarterly estimator to stay ahead of deadlines.

Which calculator should a new freelancer use first?

In this order: the hourly rate calculator to price your time, the contract rate converter to compare offers against salaries, and the tax set-aside calculator to protect every payment from day one. Everything else answers questions those three raise.
