Every tool is built for UK residents and updated each April when HMRC publishes new tax bands and thresholds.
UK VAT Calculator: Add or Remove VAT Instantly
The UK VAT calculator is one of the most used financial tools by British businesses, sole traders and freelancers. Value Added Tax is charged at three rates in the UK: the standard rate of 20%, the reduced rate of 5% applied to items such as domestic energy and children's car seats, and the zero rate of 0% covering essentials including most food, children's clothing, books and public transport.
To add VAT at the standard rate of 20%, multiply your net amount by 1.20. For example, £500 multiplied by 1.20 gives you £600 including VAT. To remove VAT from a gross amount, divide by 1.20. A common mistake is simply subtracting 20%, which is mathematically incorrect. Our UK VAT calculator handles both directions instantly.
You must register for VAT with HMRC when your taxable turnover exceeds £90,000 in any rolling 12-month period. Voluntary registration below this threshold may benefit your business if you regularly reclaim VAT on expenses. Once registered, you must use Making Tax Digital (MTD) compatible software to submit VAT returns.
UK Take-Home Pay Calculator: Net Salary After Tax
The UK take-home pay calculator shows your net salary after Income Tax, National Insurance contributions, pension deductions and student loan repayments. Your gross salary is taxed in bands. The first £12,570 is covered by the personal allowance and is tax-free. Earnings between £12,571 and £50,270 are taxed at the basic rate of 20%. Income between £50,271 and £125,140 falls into the higher rate at 40%, and any earnings above £125,140 are taxed at the additional rate of 45%.
National Insurance contributions are separate from Income Tax. Employees pay 8% on earnings between £12,570 and £50,270, then 2% on anything above. Your tax code, typically 1257L for most UK employees in 2025/26, tells your employer how much of your income is tax-free.
UK Mortgage Overpayment Calculator
Making regular overpayments on your UK mortgage is one of the most effective ways to reduce the total interest you pay over the life of the loan. Even small monthly overpayments can cut years off your mortgage term and save thousands of pounds in interest. Our UK mortgage overpayment calculator shows you exactly how much you save based on your current balance, interest rate and overpayment amount.
Most UK mortgage lenders allow overpayments of up to 10% of your outstanding balance each year without charging an early repayment fee. Always check your mortgage terms before making overpayments. For a £200,000 mortgage at 5% over 25 years, a monthly overpayment of just £100 could save over £15,000 in interest and cut around 3 years from the mortgage term.
UK Council Tax Calculator: Bands and Rates by Area
Council tax is a local tax charged by your council to fund services including rubbish collection, road maintenance and social care. Your council tax band is based on the estimated value of your home in April 1991. Properties are placed into bands from A (the lowest value) to H (the highest value) in England and Scotland, and A to I in Wales.
The amount you pay depends on your band and your local council. Many households qualify for discounts. If only one adult lives in a property, a 25% single person discount applies. Students living in full-time education may be exempt. Severe mental impairment exemptions and disability reductions can also reduce your bill significantly.
UK Rent Affordability Calculator: How Much Can You Afford?
UK letting agents and landlords use the 30x rule to assess whether a tenant can afford a property. This means your gross annual income must be at least 30 times the monthly rent. For example, if you want to rent a property at £1,200 per month, you need an annual income of at least £36,000.
Financial advisers generally recommend spending no more than 30% of your gross monthly income on rent. In London and other high-cost cities, many renters stretch to 35 to 40%, but this puts significant pressure on household finances. Our rent affordability calculator uses your income to give you a safe rental range and tells you whether you are likely to pass standard UK letting agent referencing checks.
