About WageLab

Built for people who want to understand their payslip properly.

What is WageLab?

WageLab is a free UK take-home pay calculator built for people who want to understand their payslip properly — not just see a number.

The UK tax system is genuinely complicated. Salary sacrifice reduces both your tax and your National Insurance. Relief at Source pensions work differently from Net Pay Arrangement pensions. The Personal Allowance disappears above £100,000. Most calculators ignore these details. WageLab doesn't.

What makes it different?

✓Handles all three pension methods correctly for both tax and NI
✓Applies the £100,000 Personal Allowance taper and 60% rate correctly
✓Calculates student loan repayments using HMRC monthly floor method
✓Covers all six Scottish Income Tax bands
✓Shows Adjusted Net Income — controls PA, Child Benefit, free childcare
✓Includes a mock payslip for month-by-month comparison
✓Dividend and savings income with correct band ordering
✓Cycle to Work, Gift Aid, Marriage Allowance, and Blind Person's Allowance
