Frequently Asked Questions
What's the difference between sales tax and VAT?
Value-added tax (VAT) is charged at each stage of production and is reclaimed by businesses in between, while sales tax is charged once at the final retail sale. To a shopper doing simple price math, both work exactly the same way — which is why one calculator can handle both.
How do I add tax to a price?
Enter the price before tax and the tax rate on the Add Tax tab. The calculator multiplies the price by (1 + rate / 100) to get the total, and shows the tax amount separately.
How do I remove tax from a tax-included total?
Switch to the Remove Tax tab, enter the total price that already includes tax, and the tax rate. The calculator divides the total by (1 + rate / 100) to find the price before tax.
Why do sales tax and VAT rates vary by state or country?
Each government sets its own rate, and many countries add local or state-level surcharges on top of a national rate. The quick-rate presets cover several well-known real-world rates, but always confirm the exact rate for your specific location.
Does this calculator store any of my data?
No. All calculations run locally in your browser. Nothing you enter is sent to a server, stored, or tracked.
Can this calculator be used for any country's tax rate?
Yes. Enter any rate manually, or use one of the quick-rate presets for common VAT and sales tax rates. The math works the same everywhere — only the rate changes.
What formula does this calculator use?
To add tax: Total = Price × (1 + rate/100). To remove tax: Price = Total / (1 + rate/100). Both formulas are shown live above the result as you type.
