Take-Home Pay Calculator

How do I convert between monthly and annual salary?

Multiply your monthly gross by 12 to get annual gross. Divide annual gross by 52 for weekly, or by 26 for fortnightly. This calculator does all conversions automatically from your monthly input so you can see your take-home pay in any pay period without manual arithmetic. Remember that all tax calculations are performed on the annualised figure to ensure bracket accuracy.

Why does the fortnightly amount not equal exactly half the monthly?

There are 26 fortnights and 52 weeks in a year, but only 12 months. A month averages 4.33 weeks, not exactly 4. Dividing the annual figure by the correct number of pay periods gives the most accurate per-period amount. If your employer pays fortnightly, you will receive 26 paycheques per year — not 24 — which is why the fortnightly figure is roughly 96% of twice the monthly, not exactly half.

What is not included in this estimate?

This calculator covers the main statutory deductions: income tax and primary social contributions. It does not include pension or superannuation employee contributions, student loan repayments, salary sacrifice arrangements, provincial or state taxes (for US and Canada), or employer-side costs like Australian superannuation. For Canada and the US in particular, adding provincial or state income tax can increase your effective deduction rate by a further 6–17%, so treat this result as a floor, not a complete picture.

Why is the UK take-home pay lower than expected for higher earners?

UK earners above £100,000 lose their Personal Allowance at a rate of £1 for every £2 earned above that threshold. This creates an effective marginal tax rate of 60% on income between £100,000 and £125,140, because you pay 40% income tax while also losing allowance worth another 20%. Above £125,140 the standard 40% and 45% rates apply with no Personal Allowance. This taper effect is one of the UK tax system's most counterintuitive features and can significantly reduce take-home pay for high earners.
