Free tools for tradespeople

Quoting, pricing and getting paid all come down to numbers, and getting them slightly wrong quietly adds up over a year. These free calculators do the sums for you, so a quote covers its costs, an invoice looks right, and you know exactly what will land in your bank.

What you can work out

• Add or remove VAT at 20%, 5% or 0% with the VAT calculator.
• Make and download a clean, branded PDF invoice with the invoice generator.
• Set a rate that covers your costs and pays you properly with the day rate calculator.
• Turn a markup into a margin and price for the profit you keep with the markup and margin calculator.
• See what a contractor will hold back before you're paid with the CIS deduction calculator.

They fit together the way a job does. Pricing starts with your own rate, so the day rate calculator works out what to charge for your time, and the markup and margin calculator makes sure the profit you add is the profit you keep, because a markup and a margin are never the same number. Once the job is priced, the VAT calculator gets the tax right and the invoice generator turns it into something you can send from your phone. If you work as a subcontractor, the CIS calculator shows exactly what will be deducted before you're paid.

Built for UK trades, free and private

Every tool here is built for UK trades, with UK VAT rates, CIS deductions and pounds throughout, and each one works in any browser: on a phone standing on the job, or a laptop at the kitchen table. They're free and always will be. There's no account to create and no data to hand over, because the maths runs in your browser and disappears when you close the tab. Download or print anything you want to keep.

If you want the thinking behind the numbers, the blog goes deeper on how to price a job so you actually make a profit, how to set a day rate that stops you undercharging, and how to get paid faster once the work is done.
