BillableMath is a small collection of free calculators that help freelancers and independent contractors answer one hard question: what do I actually need to charge?
Most pricing advice hands you a number someone else earns. Our tools do the opposite — they start from the take-home pay you want and work backward through self-employment tax, business expenses, and the large share of every week that is never billable. You fill in every figure, including your own tax rate, so nothing goes stale and nothing pretends to be tax advice.
Every calculator runs entirely in your browser. We store nothing you type. Each tool is plain arithmetic that you could check by hand, and we verify the math against worked examples before publishing.
These are planning tools, not tax, accounting, or financial advice. For decisions with real consequences, talk to a qualified professional. Questions or corrections are welcome at hello@billablemath.com.
