Free calculators built for self-employed tradespeople. Work out your real day rate, price jobs properly, and see exactly what you take home — all without signing up.
Three steps to knowing exactly what you need to charge.
Your target take-home pay, overhead costs, and how many days you actually work. Pre-filled with realistic defaults for your trade.
See your minimum day rate, tax and NI breakdown, and how you compare to typical rates in your region — all in seconds.
Know the minimum you need to charge to cover your costs, hit your income target, and build a profitable business.
Each tool is free, requires no sign-up, and works on any device.
Most tools just ask "what salary do you want?" and divide by 260. That's not how it works.
Van, tools, insurance, non-billable days — most calculators miss these entirely.
Income tax and Class 4 NI calculated automatically so you know your real take-home.
See how your calculated rate compares to typical rates in your area of the UK.
Pre-filled with realistic costs for your trade — just adjust to match yours.
