How to use the stacked discounts
Enter amount, first discount (%), and second discount (%). Choose the currency for your inputs and read the result as you change the values.
How it works and formula
Final price = price × (1 − first rate) × (1 − second rate).
Worked example
| Amount | 100 |
|---|---|
| First discount (%) | 20 |
| Second discount (%) | 10 |
Result
Final price $72.00 · Combined discount 28.00%
Try a second calculation
Start with the USD worked example above and change only second discount (%) to 15. Select Calculate. Your result should read:
Final price $68.00 · Combined discount 32.00%
Then enter 5 in the same field. Compare the result with the first scenario row. Holding every other input steady lets you see exactly how this one change affects the calculation.
Choosing your inputs
Apply each percentage to the price remaining after the previous discount. For a store markdown followed by a member offer, enter the original ticket price and the two percentage rates. A fixed-value voucher needs a different calculation.
How to interpret the result
Use the combined discount to compare a two-part offer with a single percentage offer. Two equal discounts give a smaller combined reduction than their sum because the second applies to less money. Check whether the retailer permits both offers on your item.
Frequently asked questions
