Calculate the sale price, how much you save and the final total after VAT, GST or sales tax. Works with any currency and updates instantly.
The Discount & Sales Tax Calculator works out the sale price of an item, how much you save, and the final total once VAT, GST or sales tax is applied, all updating instantly as you type. It handles both a simple percentage-off discount and the tax added afterwards, which is exactly the two-step maths involved in most real purchases.
Because the calculator works with any currency symbol and any tax rate, it suits shoppers comparing sale prices, and small businesses working out pricing that includes local tax rules. Enter the original price, discount percentage and tax rate, and every figure — savings, discounted price and final total — appears together.
Most real-world purchases involve both a percentage discount and tax added afterwards; calculating each figure together avoids the common mistake of applying tax to the original price instead of the discounted one.
There is no fixed currency or region built in, so the calculator applies equally to VAT in the UK and EU, GST in countries that use it, or general sales tax elsewhere, using whatever rate you enter.
Changing the discount percentage or tax rate updates every figure immediately, making it quick to compare two competing sale offers or check whether an advertised saving is accurate.
Multiply the original price by the discount percentage and divide by 100 to get the amount saved, then subtract that from the original price to get the discounted price. A £50 item with a 20% discount saves £10, bringing the price to £40 before any tax is added.
Sales tax, VAT or GST should generally be calculated on the discounted price, not the original price, since that is the amount actually being charged. Applying tax to the pre-discount price would overstate the final total compared with what most retailers actually charge at checkout.
VAT (used in the UK and EU) and GST (used in countries like Australia and Canada) are typically included in the displayed shelf price, while US-style sales tax is usually added at checkout on top of the shown price. This calculator handles both approaches depending on how you interpret the entered original price.
Multiply the original price by the discount percent and divide by 100 to get the saving, then subtract it from the price. Enter both values and the tool shows every step.
