Frequently asked questions
How do I find the original price from a sale price?
Divide by (1 − discount). $60 at 25% off → $60 ÷ 0.75 = $80. Use the reverse tab above.
Is '30% off then extra 20% off' the same as 50% off?
No! It's 44% off — discounts multiply: 0.7 × 0.8 = 0.56. Retailers count on this confusion.
Discount vs markup — same thing?
Mirror images. Discount reduces from the selling price; markup adds to cost. Our Profit Margin calculator covers markup.
How do I quickly estimate 15% off?
10% (move decimal) + half of that (5%). $80 → $8 + $4 = $12 off → $68.
