Understanding Your Take Home Pay
Your take home pay is what's left after Income Tax, National Insurance, pension contributions, and other deductions are taken from your gross salary. Understanding these deductions helps you budget effectively and make informed decisions about salary negotiations, pension contributions, and tax-efficient benefits.
The UK tax system uses progressive tax bands, meaning you pay different rates on different portions of your income. Our calculator accounts for all current tax rates, allowances, and thresholds to give you an accurate picture of your net income.

Frequently Asked Questions
How accurate is the take home pay calculator?
Our calculator uses the latest HMRC tax rates and thresholds for 2024/25. It accounts for Income Tax, National Insurance, pension contributions, and student loans. Results should match your payslip closely, though specific circumstances like benefits in kind may cause variations.
Why is my take home pay different from the calculator?
Differences can occur due to: incorrect tax code, benefits in kind, salary sacrifice schemes, court orders, union dues, or company-specific deductions. Check your payslip for additional deductions and ensure your tax code is correct.
What's the 60% tax trap?
Between £100,000 and £125,140, you lose £1 of personal allowance for every £2 earned. Combined with 40% tax, this creates an effective 60% tax rate. Consider pension contributions or salary sacrifice to reduce income below £100,000 if possible.
How does child benefit affect my tax?
If you or your partner earn over £50,000 and claim child benefit, you'll pay the High Income Child Benefit Charge. It's 1% of child benefit for every £100 earned between £50,000-£60,000. Above £60,000, the entire benefit is reclaimed through tax.
Should I opt out of my workplace pension?
Generally no. You'll lose employer contributions (free money), tax relief on contributions, and compound growth over time. Only consider opting out if you have severe debt problems or are very close to retirement with adequate provision already.
How do bonuses affect my tax?
Bonuses are taxed as regular income through PAYE. Your employer may initially deduct tax at basic rate, but if the bonus pushes you into a higher tax bracket, additional tax will be collected through your tax code adjustment or self-assessment.
