Built by a former contractor who's done the sums both ways

I’m Steve, a UK tech professional. For a number of years I contracted through my own limited company, outside IR35, before the 2021 rule changes. These days I’m permanent again, so I’ve weighed up the same question you’re facing from both sides of the table.

The calculators I found online answered the wrong question: they’d tell me my take-home, but not whether it beat the job I already had, or what rate I should hold out for. NetDayRate is the tool I wanted then. Move any number and the other two follow.

The figures come straight from GOV.UK and are checked every April. Every assumption is written down on the How we calculate page, so you can check my working.

The site is free and has no sign-up. It pays for itself through a small number of clearly marked links to contractor accountants and similar services. Those links never change the numbers or the order anything’s shown in.

It isn’t financial advice. Before you sign anything, talk to an accountant who knows your situation.

NetDayRate is run by Klever Labs. Get in touch if you spot a mistake or have a question about how a number was reached.
