What Does “Percent Off” Mean?
“Percent off” is the share of the original price a store takes away. 40% off means you save 40 cents of every dollar and pay the other 60%. To get the sale price, multiply the tag price by (100 − percent off) ÷ 100: 40% off $120 is $120 × 0.60 = $72.

Percent Off Calculator FAQs
Subtract the percent off from 100, divide by 100 and multiply by the price. For 40% off $120: (100 − 40) ÷ 100 = 0.60, and $120 × 0.60 = $72.
20% off $50 is $40. You save $10, because 10% of $50 is $5 and 20% is double that.
25% off $40 is $30. A quick shortcut for 25% off is to divide the price by 4 to find the saving ($10).
30% off $80 is $56. Multiply $80 by 0.70, or take 10% ($8) three times and subtract $24.
Fifteen percent off means you pay 85% of the price. On $60 that is $51, a saving of $9 (10% = $6 plus 5% = $3).
70% off means you pay only 30% of the original price. A $200 coat at 70% off costs $60.
