Open VAT CalculatorHow these shopping and tax calculators fit together
Shopping and tax calculations share a common foundation: percentages. The percentage calculator handles the underlying math, while the discount, sales tax and VAT calculators apply it to specific real-world scenarios. Understanding percentages makes all four tools more intuitive.
Choosing the right tool
- General percentage questions: use the percentage calculator for any "what is X% of Y" or "percentage change" question.
- Sale prices and coupons: use the discount calculator when a price is reduced by one or more percentages plus a fixed coupon.
- US-style sales tax: use the sales tax calculator to add tax to a pre-tax price or extract it from a tax-inclusive total.
- VAT and GST: use the VAT calculator for value-added tax calculations common in Europe, the UK, Australia and many other regions.
Tax rates vary — always verify
Sales tax and VAT rates vary by country, state, product category and sometimes by the buyer's location. These calculators let you enter any custom rate rather than using hard-coded values. Always verify the applicable rate with the relevant tax authority before making financial decisions.
