DocomintDiscount / Sale Price Calculator
Calculate a sale price and savings amount from an original price and a discount percentage.
A one-step version of a calculation people usually do in their head at the register or while shopping online — enter the sticker price and the advertised discount to see exactly what you'll pay and exactly how much you're saving, without doing the percentage math yourself.
Example: A $80 jacket marked 25% off comes to a $60 sale price, saving $20 — useful for quickly comparing a "25% off" sign against a "$20 off" sign on an identical item to see they're actually the same deal here.
How it works
- Enter the original price and the discount percentage
- Press Calculate
- The sale price and amount saved appear instantly, calculated on your device
Frequently asked questions
How do you calculate a percentage discount?
Multiply the original price by the discount percentage to get the amount saved, then subtract that from the original price for the sale price. A $80 item at 25% off saves $20 (80 × 0.25), for a $60 sale price.
How do I calculate two discounts applied one after another?
Apply them sequentially, not by adding the percentages — a 20% discount followed by a 10% discount is not a flat 30% off. Run this calculator once for the first discount, then run it again using that result as the new "original price" for the second discount.
