How to Calculate 80% Off
To find 80% off any price, multiply the original price by 0.80 — that gives you the discount amount. Subtract it from the original to get the final sale price.
Formula:
Discount = Original × 0.80
Sale Price = Original − Discount
Example: 80% off $80
Discount = $80 × 0.80 = $64.00
Sale Price = $80 − $64.00 = $16.00
