About Darisy
UK money calculators that don't waste your time.
Darisy exists because UK money is unnecessarily complicated. Salary sacrifice. IR35. Marriage allowance. The 60% tax trap. Most calculators on the internet either skip this stuff or get it wrong.
What we do
We build calculators that handle the real edge cases — accurate to HMRC rates, transparent about assumptions, and fast enough to play with. We pair them with plain-English guides so you actually understand what the numbers mean.
Who we are
A small team of engineers and writers, based in the UK. We're not financial advisers and we don't sell financial products. We earn money via affiliate links to brokers we'd actually use — see our affiliate disclosure.
Our principles
1. Accuracy first. If we get a number wrong, we fix it.
2. No dark patterns. No fake urgency, no email-walls, no required signups.
3. Affiliate doesn't trump editorial. Best brokers win, regardless of who pays.
