About the Discount Calculator
The Discount Calculator subtracts a percentage from the listed price, then optionally applies tax to the discounted subtotal. It separates savings, tax and final price.
How to use the Discount Calculator
- Enter the pre-discount price.
- Add the advertised discount and any post-discount tax.
- Calculate and compare the final amount.
Practical tips
- Successive discounts are applied one after another, not normally added together.
- Check whether displayed prices already include local tax.
