Calculators
The calculations that come up most often with HMRC, with an accountant and at a border. Everything runs in your browser: we never see your figures or your dates, and nothing is stored.
VAT: add it and take it out
Enter an amount and pick a rate. You get the net figure, the tax itself and the gross — the three numbers an invoice needs.
Take-home pay
A gross annual salary — and what is left after income tax and National Insurance. For England, Wales and Northern Ireland, tax year 2026/27.
Schengen days: 90 in 180
Since April 2026 the days are counted by the EES, not by an officer reading stamps. Enter your trips and see how many days are used on a chosen date and how many remain.
Absences and the road to settlement
You live by the rules for five years and then find that one long trip home broke the continuity. Enter your trips and see whether you stay within the limit. The three routes have different rules — pick yours.
Currency converter
On our sterling rates and the official rates of the region’s central banks. For reference, not for dealing: your bank or transfer service will use its own rate and add a fee.
Checks against government registers
The UK sanctions list, a VAT number in the HMRC register, a company in Companies House, a postcode. The query goes straight to the register and we do not store it.
These calculators are for reference and do not replace an accountant, a tax adviser or a solicitor. Rates and thresholds change — check GOV.UK before acting.
