59 calculators across 24 sectionsMoney
What comes in, what the taxman takes, what you owe and what you're building.
Property
Buying, renting, moving and letting. The biggest numbers on the site.
Bills
The recurring outgoings that quietly set your monthly floor.
Family
Costs you take on for other people, from a first pet to later-life care.
Lifestyle
Costs you choose. Worth knowing before you commit to them.
Where the numbers come from
Tax bands, National Insurance and student loan thresholds are taken from HMRC and gov.uk for 2026/27, and listed in full on every page that uses them.
What this is not
Arithmetic, not advice. Nothing here recommends a product, a lender or a course of action, and no result is a decision you should act on alone.
Nothing is stored
Every calculation runs in your browser. No account, no saved figures, no data sent anywhere.
