How This Calculator Works
Enter the original price and the discount percentage. The calculator multiplies the price by the discount to find the saving, then subtracts it from the original price to give the sale price — the amount you actually pay at the till.
The Formula
Percentage of an Amount
Amount is the base value, Percentage is the rate applied to it
Worked Example
An item priced at $80 with a 25% discount saves you $20. The sale price is $60. A larger discount lowers the sale price further, but the saving is always measured against the original, pre-discount price.
Key Insight
Two discounts do not simply add up. A 20% discount followed by a further 20% off is not 40% off — the second discount applies to the already-reduced price, giving 36% off in total.
Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percentage and divide by 100 to find the saving, then subtract that from the original price to get the sale price.
Do stacked discounts add together?
No. A second discount applies to the already-reduced price, not the original. Two 20% discounts give 36% off in total, not 40%.
What is the difference between the saving and the sale price?
The saving is how much the discount takes off; the sale price is what you pay. The saving plus the sale price always equals the original price.
Does the discount apply before or after tax?
Discounts are normally applied to the pre-tax price, with sales tax then charged on the reduced amount. Enter the pre-tax price for an accurate sale price.
How do I find the percentage off from two prices?
Subtract the sale price from the original, divide by the original, and multiply by 100. That gives the discount as a percentage.

Methodology & Review
The saving is the original price multiplied by the discount percentage; the sale price is the original price minus that saving. The calculator handles a single discount, not stacked offers.
