Discount calculator
Spotting a sale tag and want the real price fast? Put in the original price and the percentage off, and this shows what you will actually pay, the cash you save, and the discount restated as a clear percentage. It is the quick check for a shop window deal, a voucher code at the checkout, or comparing two offers that are framed differently. Knowing the saving in money, not just a percentage on a sticker, makes it easier to judge whether a reduction is as good as it looks.
How it works
- Enter the original, full price of the item.
- Enter the discount percentage shown on the label or voucher.
- The final price is the original multiplied by one minus the discount as a decimal.
- The saving is the original price minus that final price.
final = original x (1 - rate); saving = original - final
The discount as a decimal is taken away from one, so 25 percent off becomes a factor of 0.75. Multiplying the original price by that factor gives what you pay. The saving is simply the original price minus the discounted price, which also equals the original multiplied by the discount itself. Both views describe the same reduction.
- original
- the full ticket price before any cut
- rate
- discount as a decimal, e.g. 0.25 for 25 percent
- final
- the price you actually pay
What a discount really takes off
| 10% off | pay 90% of the price | a tenth saved |
| 25% off | pay 75% | a quarter saved |
| 50% off | pay half | the classic sale |
| Two-thirds off | pay about 33% | a deep clearance cut |
Worked example
An item priced 80 with 25 percent off: you pay 60 and pocket a 20 saving (80 x 0.75 = 60). A deeper 40 percent cut on the same item would bring it to 48, saving 32.
Key facts
- Stacking a 20 percent then a 10 percent discount gives 28 percent off, not 30, because the second cut applies to an already reduced price.
- A "50 percent extra free" pack is not 50 percent off; it works out at about a third off the unit price.
- The cash saved depends entirely on the starting price, so the same percentage saves far more on a sofa than on a sandwich.
- Halving a price twice leaves you paying a quarter, a 75 percent total reduction.
Tips
- To compare a money-off voucher with a percentage deal, convert the voucher to a percentage of the price you would actually pay.
- For two discounts, run the first through the tool, then feed its result back in as the new original price.
- Check whether the percentage applies before or after VAT, as a few retailers quote it on the pre-tax figure.
- Ignore the size of the percentage and look at the cash saving when deciding if a deal is worth a special trip.
Discount on an 80 item
| Percent off | You pay | You save |
|---|---|---|
| 10% | 72.00 | 8.00 |
| 25% | 60.00 | 20.00 |
| 40% | 48.00 | 32.00 |
| 50% | 40.00 | 40.00 |
Frequently asked questions
Can I combine two discounts?+
Apply them in sequence rather than adding the percentages. A 20 percent reduction followed by a further 10 percent is not 30 percent off; it works out at 28 percent. Feed the first result back in to get the second.
Is VAT or sales tax included?+
No. The calculation works purely on the ticket price. If you need tax added or stripped out, use the dedicated VAT or sales tax tool instead.
How do I check a "buy one get one half price" deal?+
Across the two items that offer averages to 25 percent off each. Enter 25 percent on the combined price to compare it fairly against a straight discount.
What does the percentage-off figure tell me?+
It confirms the headline discount as a proportion of the original price, which is handy when a tag only quotes a money saving and you want the percentage.
