VAT Calculator UK — Calculate VAT on Any Amount
Add or remove VAT from any amount instantly. Calculate net and gross prices with standard 20% reduced 5% and zero rate VAT for UK businesses and consumers.
Value Added Tax is charged on most goods and services in the UK at the standard rate of 20%. Some items like home energy and child car seats have a reduced rate of 5% while essentials like most food items and children clothing are zero-rated. Whether you are a business calculating VAT on invoices or a consumer trying to find the pre-VAT price of a purchase our calculator handles all three VAT rates and works in both directions adding VAT to a net price or removing VAT from a gross price.
How do I calculate VAT from a total price?
To find the VAT included in a gross price at 20% divide the total by 1.2 to get the net amount then subtract the net from gross to get the VAT. For example if the total is £120 the net price is £100 and VAT is £20. For 5% VAT divide by 1.05 instead. This reverse calculation is essential for business bookkeeping and expense claims.

How Tax Calculation Works
Income tax is calculated on your total taxable income after deducting eligible exemptions and deductions from your gross income. The tax is applied progressively — you pay a lower rate on initial income slabs and higher rates only on income that exceeds each threshold. This means moving into a "higher tax bracket" does not mean your entire income is taxed at the higher rate. Understanding marginal vs effective tax rate is crucial: your marginal rate applies only to the last rupee earned, while your effective rate is the average across all slabs.
Tax-Saving Strategies
Under the old regime, maximize deductions: Section 80C allows up to Rs 1.5 lakh through PPF, ELSS, EPF, and life insurance. Section 80D covers health insurance premiums up to Rs 25,000 (Rs 50,000 for senior citizens). Section 80CCD(1B) offers an additional Rs 50,000 deduction for NPS contributions. Home loan interest up to Rs 2 lakh is deductible under Section 24. Under the new regime, the Rs 75,000 standard deduction and lower slab rates may save you more if your total deductions are below Rs 3.75 lakh. Calculate under both regimes before choosing.

When do I need to register for VAT?
You must register for VAT when your taxable turnover exceeds £90000 in any rolling 12 month period or you expect to exceed it in the next 30 days. You can voluntarily register below this threshold which lets you reclaim VAT on business purchases. Voluntary registration can benefit businesses that sell mainly to other VAT registered businesses.
What items are VAT exempt in the UK?
VAT exempt items include insurance financial services education provided by eligible bodies health services by registered practitioners postal services by Royal Mail and certain property transactions. Note that exempt is different from zero-rated. If you only make exempt supplies you cannot register for VAT or reclaim input VAT. Zero-rated items like most food and children clothing are technically taxable at 0% allowing VAT registration and input VAT recovery.
What are the UK income tax bands for 2025-26?
Personal Allowance: £0-£12,570 (0%). Basic rate: £12,571-£50,270 (20%). Higher rate: £50,271-£125,140 (40%). Additional rate: over £125,140 (45%). The personal allowance reduces by £1 for every £2 earned over £100,000, creating an effective 60% rate between £100,000-£125,140.
What is the £100,000 tax trap?
When your income exceeds £100,000, you lose £1 of personal allowance for every £2 over. This creates a hidden 60% effective tax rate between £100,000-£125,140. Pension contributions are the most effective way to bring your income below this threshold and reclaim the allowance.
