Your salary is not your pay
The number in your job offer has never landed in your bank account.
Three main deductions cause this — and every single one is explained on this site.
You're probably here for one of two reasons:
- A pay rise or job offer is on the table, and you want to know what it's actually worth before signing.
- You're staring at a current payslip, wondering where the missing chunk went.
This calculator answers both in under 30 seconds. Drop in your current salary and a target offer to map your monthly take-home side-by-side, with every deduction broken down line-by-line.
Alternatively, leave the second salary the same as the first and it simply explains the payslip you already have.
