Two ways to work out a discount: give a price and a percentage to see the sale price and your saving, or give the original and sale price to find out what percent off it really is. Everything runs in your browser, so it is instant and private — handy right in the shop.
Enter a price and a discount.
How it works
In percentage mode the saving is the price times the percentage, and the sale price is what remains. A 2,000 item at 30% off saves 600 and costs 1,400. In sale-price mode the tool does the reverse: the saving is original minus sale price, and the percent is that saving as a share of the original.
Sale-price mode is the useful one for checking a shop’s claim: enter the original and the tagged price and see the true percentage. A jacket marked down from 2,999 to 1,999 is a 33.34% cut, not the “half price” a sticker might imply. All figures are rounded to two decimals.
Practical examples
A 30%-off sale
A 2,000 RSD item at 30% off: you save 600 and pay 1,400. Change the percentage to compare a 20% versus 40% sale on the same item.
Checking a marked-down tag
A price tag shows 2,999 crossed out, 1,999 now. Switch to sale-price mode: that is a 33.34% discount and a 1,000 saving — the real number behind the sticker.
Stacking against VAT
The discount applies to the shelf price, which in Serbia already includes VAT. To split a receipt into net and VAT after the discount, take the sale price into the VAT calculator.
Frequently asked questions
How do I calculate a percentage discount?
Multiply the price by the discount percentage to get the saving, then subtract it from the price for the sale price. For example 30% of 2,000 is 600, so the item costs 1,400. Percentage mode does this for you.
How do I find the discount percent from a sale price?
Switch to sale-price mode and enter both the original and the reduced price. The tool computes the saving (original minus sale) and expresses it as a percentage of the original — the honest discount rate.
Is the discount applied before or after VAT?
On the shelf price. In Serbia displayed prices already include VAT, so the discount comes off that inclusive figure. There is no separate pre-VAT discount to calculate for ordinary retail shopping.
Can I calculate two discounts stacked together?
Not in one step — stacked discounts don’t simply add. Apply the first discount, take the resulting sale price, and run it through again for the second. Two 20% discounts are a 36% total cut, not 40%.
What does a “50% off” really save me?
Exactly half the price. Discounts get less dramatic as the percentage falls: 50% halves the price, but 30% still leaves you paying 70%. Sale-price mode is the quickest way to see through generous-sounding signs.
Does it work in any currency?
Yes. The tool is currency-neutral — enter dinars, euros or anything else and the result is in the same unit. It never assumes or converts currencies.
Why is the discount percent shown with decimals?
Real markdowns rarely land on round numbers. Reducing 2,999 to 1,999 is 33.34%, not a clean third. Showing two decimals keeps the figure honest rather than rounding a claim up to look bigger.
Are the prices I enter stored anywhere?
No. The calculation happens entirely in your browser. Nothing is uploaded, and analytics never sees the prices.
