Open calculatorWhy this site is useful
- Each calculator is focused on a single UK question.
- Results are shown with a plain-English breakdown, not just a number.
- Assumptions are surfaced so you can spot when a scenario needs official advice.
- Pages are designed for mobile first and keep ads away from the main calculation flow.
How it works
- Enter only the fields needed for the calculation.
- See the headline figure immediately, plus supporting rows below it.
- Review the assumptions, statutory caps, or source note under the result.
- Jump to a related calculator if your question changes.
Rules and data are reviewed regularly, especially around annual UK updates. The static
format keeps pages fast and inexpensive to maintain while still letting us ship clear
update notes and source references.
Common questions
Are these calculators a replacement for legal or payroll advice?
No. They are designed around public UK guidance and common statutory scenarios. If a
case is unusual, contractual, or disputed, you should still check the official guidance
or get professional advice.
Why do some pages mention assumptions?
Employment and payment rules often change depending on the exact contract or context.
Clear assumptions help you tell whether a quick calculator result fits your situation.
Will more calculators be added?
Yes. The site is structured as a focused mini-site, so related UK tools and guidance
pages can be added without redesigning the whole experience.
