How to Calculate 90% Off

To find 90% off any price, multiply the original price by 0.90 — that gives you the discount amount. Subtract it from the original to get the final sale price.

Formula:
Discount = Original × 0.90
Sale Price = Original − Discount
Example: 90% off $80
Discount = $80 × 0.90 = $72.00
Sale Price = $80 − $72.00 = $8.00
