Payslip Breakdown Calculator

A 5,000 gross monthly pay with 25% tax, 5% pension, and 50 of other deductions produces 3,450 net — 1,250 tax, 250 pension, 50 other. Tax alone is 25% of gross, but the combined effective deduction rate is 31%. Comparing jobs on take-home rather than gross makes the real gap visible.

How to use it

Enter gross monthly pay and your own rates: effective income tax rate (your marginal rate or band average), pension contribution rate, and any other flat monthly deduction. The tool keeps jurisdiction-agnostic — you supply the rates.

What the result means

Primary is net take-home. Secondary rows show each deduction in absolute terms and the total effective deduction percentage. Use it to see how pay changes when one of the three inputs moves.

Why this isn't a jurisdiction-specific tool

Because tax bands change every year and differ by country. Building in specific bands would mean constant maintenance and a shelf-life of under a year. Letting you enter rates keeps the tool correct indefinitely at the cost of slightly more user effort.

Run it with sensible defaults

Using gross monthly pay of 5,000, effective tax rate of 25%, pension contribution of 5%, other flat deductions of 50, the calculation works out to 3,450.00. The defaults are meant as a starting point, not a recommendation.

The levers in this calculation

The inputs — Gross Monthly Pay, Effective Tax Rate, Pension Contribution, and Other Flat Deductions — do not pull with equal force. Not every input has equal weight. Adjusting one input at a time toward extreme values shows which ones move the result most.

How the math works

Net take-home equals gross minus (tax rate × gross) minus (pension rate × gross) minus fixed other deductions. User supplies rates to keep the tool evergreen across jurisdictions. For jurisdictions where tax applies differently to pension contributions (e.g., pension sacrifice), adjust the tax rate downward to reflect the post-sacrifice effective rate.

What the headline number hides

Gross pay, net pay, and what actually lands in your account can differ by thousands depending on tax code, benefits, pension contributions, and student loan deductions. This tool isolates one piece of that picture — always pair it with a take-home calculator for the full view.

What this doesn't capture

Tax bands, pension contributions, student-loan deductions, and benefits-in-kind sit outside this calculation. The figure is the headline; your actual position depends on local tax rules and personal circumstances. Pair with a dedicated take-home calculator for the full picture.
