Why we built this
Most UK workers don't fully understand their payslip. The figures are there — gross pay, PAYE, National Insurance, pension — but what they mean and whether they are correctis rarely obvious. One in three workers is on the wrong tax code at some point. Emergency codes cost people hundreds of pounds a month. Payroll errors go unchallenged because most workers don't know how to verify the numbers.
We built Payslip Checker to fix that. Enter your gross pay and get a complete, visual breakdown of every deduction — calculated in your browser, instantly, with no signup and no data stored anywhere.
How it works
All of our calculators run entirely in your browser using JavaScript. When you enter your salary, tax code, pension, and student loan details:
- The calculation runs locally on your device
- Results are displayed instantly — no server round-trip
- No financial data is transmitted to us at any point
- Your inputs are cleared when you close the page (unless you use the Compare feature, which uses local browser storage)
Our PAYE, National Insurance, and student loan calculations use the official 2026/27 rates published by HMRC. We update them every April when the new tax year begins.
Who is this for?
Payslip Checker is built for any UK worker who wants to:
- Check whether their payslip deductions look correct
- Understand what their tax code means and whether it's right
- Calculate their take-home pay before accepting a new job offer
- Compare Scottish vs English take-home at any salary
- Understand how much tax they'll pay on a bonus or overtime
- See how pension contributions (including salary sacrifice) affect their take-home
- Understand the impact of student loan deductions
Our commitment to accuracy
We use the official HMRC rates and thresholds for each tax year, sourced directly from GOV.UK. Our calculators are reviewed by our editorial team each April and whenever HMRC announces changes. All content is fact-checked against primary HMRC sources before publication.
However, we are not a regulated financial service and our calculations are educational estimates — not guaranteed payroll results. Your employer's payroll software may produce slightly different figures due to cumulative PAYE adjustments, week-1/month-1 basis, or employer-specific deductions.
For authoritative figures, always refer to GOV.UK Income Tax or speak to your payroll team.
How we're funded
Payslip Checker is free to use. We earn revenue through two routes: Google AdSense advertising displayed on the site, and clearly labelled affiliate referral links to relevant financial services (such as RIFT Tax Refunds, PensionBee, and Unbiased.co.uk). Our editorial content is never influenced by these commercial relationships. We only link to services we believe are genuinely useful to our readers.
