All UK Tax & Personal Finance Calculators

How Much Tax Do I Really Pay?

See a full breakdown of Income Tax, National Insurance, VAT and Council Tax against your income, and how much you really keep.

UK Salary Calculator

Enter your salary to estimate your take-home pay after Income Tax, employee National Insurance, pension contributions and student loan repayments – shown by year, month, week or day.

Salary Sacrifice Pension Calculator

Enter your salary and how much of it you want to send to your pension, as a percentage or in pounds. You will see the amount both ways, the Income Tax and National Insurance you save, and what it really costs your take-home pay.

NHS Pay Calculator

Estimate take-home pay for NHS England staff on Agenda for Change, for 2026/27, 2025/26 or 2024/25. Select your band and pay point rather than entering a salary directly, and this calculator works out your gross pay, NHS Pension contribution, tax, National Insurance and student loan. This calculator covers England Agenda for Change staff only, not doctors, dentists, Very Senior Managers, or staff in Scotland, Wales or Northern Ireland.

UK National Insurance Calculator

Estimate employee Class 1 National Insurance on your annual employment income for 2026/27, 2025/26 or 2024/25, assuming the standard Category A. This calculator provides an annual estimate; employee National Insurance is normally calculated separately for each pay period, so your actual payroll deductions can differ if your earnings vary during the year.

UK Bonus Tax Calculator

Getting a bonus on top of your normal salary changes what you take home, but not by a simple flat percentage. Enter your normal salary and bonus amount to see the extra Income Tax, National Insurance and Student Loan deductions the bonus causes, and how much of it you actually keep.

UK Student Loan Repayment Calculator

Estimate your annual UK Student Loan repayment for 2026/27, 2025/26 or 2024/25. Select your undergraduate repayment plan and whether you also have a Postgraduate Loan; this calculator works out what you repay above each applicable threshold.

UK Total Income Tax Calculator

Combine salary, self-employed profit, UK residential rental income, savings interest and dividends into one Income Tax and National Insurance estimate, using one Personal Allowance for your whole income. Leave any section at £0 if it does not apply to you. This is an estimate, not a Self Assessment calculation.

UK Income Tax Calculator

Estimate how much Income Tax you will pay on your annual income for 2026/27, 2025/26 or 2024/25, including your Personal Allowance and applicable tax bands. This calculator covers Income Tax only; use the Salary Calculator for full take-home pay.

UK Dividend Tax Calculator

Estimate the total UK Income Tax caused by your dividends for 2026/27, 2025/26 or 2024/25. This includes the Dividend Tax charged directly on your dividends, and any extra ordinary Income Tax caused if your dividends reduce your Personal Allowance.

UK Savings Interest Tax Calculator

Estimate the tax due on your UK savings interest for 2026/27, 2025/26 or 2024/25. Tax on savings interest depends on your other income, your Personal Allowance, the Starting Rate for Savings and your Personal Savings Allowance, not a flat percentage of your interest.

Child Benefit Tax Charge Calculator

Enter your income and how many children get Child Benefit to see how much of it you would pay back through the High Income Child Benefit Charge for 2026/27, 2025/26 or 2024/25.

Pension Tax Relief Calculator

Enter your income and what you pay into a personal pension or SIPP to see the tax relief your provider adds and any extra you can claim back for 2026/27, 2025/26 or 2024/25.

Capital Gains Tax Calculator

Enter what you sold something for, what it cost and your income to estimate the Capital Gains Tax due for 2026/27 or 2025/26.

UK Rental Income Tax Calculator

Estimate how much Income Tax you may pay on UK residential rental income as an individual landlord, after allowable expenses, property losses and residential mortgage finance-cost relief, taking your other taxable income into account. This is an estimate, not a Self Assessment calculation.

UK Mortgage Calculator

Estimate monthly mortgage repayments, total interest and loan-to-value for a repayment or interest-only mortgage. This is an estimate for general guidance, not a mortgage offer, affordability assessment or lending decision.

UK Stamp Duty Calculator

Estimate Stamp Duty Land Tax (SDLT) on a residential property purchase in England or Northern Ireland, for a standard purchase, a qualifying first-time buyer purchase, or an additional property. This calculator does not cover Scotland or Wales, which have their own property transaction taxes.

UK Council Tax Calculator

Select your council and Council Tax band for an estimate of your annual and monthly Council Tax in 2026/27. Covers England, Wales and Scotland. Council Tax is a separate household bill, not a deduction from your pay; an optional take-home pay comparison is shown separately below, clearly labelled, never merged into any payroll figure.

UK Self-Employed Tax Calculator

Estimate Income Tax and Class 4 National Insurance for UK self-employed sole traders, for 2026/27, 2025/26 or 2024/25. This calculator is for sole traders only, not limited companies or company directors.

UK Employed and Self-Employed Tax Calculator

If you are employed and also self-employed, your Income Tax is calculated on your combined income together, not as two separate calculations. Enter your salary and self-employed profit to see your total estimated tax and National Insurance, and the extra amount your self-employed profit adds.

CIS Deduction Calculator

Enter a construction invoice and the materials on it to see how much the contractor deducts under the Construction Industry Scheme (CIS), and how much the subcontractor is paid.

UK VAT Calculator

Add VAT to a net amount, remove VAT from a VAT-inclusive amount, or work out the VAT amount itself, using the standard, reduced, zero or a custom VAT rate.
