Calculate sales tax for purchases in different countries with varying tax rates.
Tax Amount = Price × (Tax Rate / 100). Total Price = Price + Tax Amount. Example: £100 item at 20% VAT = £20 tax, total = £120.
Pre-tax Price = Final Price ÷ (1 + Tax Rate/100). Example: £120 ÷ 1.20 = £100 pre-VAT.
The standard UK VAT rate is 20%. Reduced rate is 5% for some goods (e.g. children's car seats, home energy). Zero rate applies to most food and children's clothing.
US sales tax varies by state and even by city. It ranges from 0% (Oregon, Montana, Delaware, New Hampshire, Alaska) to over 10% in some cities.
