Discount% = ((Original - Sale) / Original) * 100 Sin cálculos aún.
Cómo calcular
% Off = ((Original − Sale) ÷ Original) × 100
To find the percentage off, subtract the Sale Price from the Original Price to get the total savings amount: Savings = Original Price − Sale Price. Next, divide the Savings by the Original Price to determine the decimal proportion saved. Finally, multiply this decimal by 100 to express the savings as a percentage: Percentage Off = ((Original Price − Sale Price) ÷ Original Price) × 100.
* Ejemplo: $100 → $75 → 25% off

Preguntas frecuentes
How do I calculate what percentage off a sale price is?
Subtract the sale price from the original price, divide that difference by the original price, and multiply by 100. For example, if a $50 shirt is sold for $35, the difference is $15. $15 divided by $50 equals 0.30, which translates to 30% off.
What percentage off is saving $15 on a $60 item?
Saving $15 on a $60 item represents a 25% discount. Dividing $15 by $60 gives 0.25, which equals 25%.
Is percentage off calculated on the pre-tax or post-tax price?
Percentage off is calculated on the pre-tax original list price. Comparing pre-tax numbers ensures accurate percentage evaluation regardless of local tax rates.
What is the difference between percentage off and percentage discount?
Mathematically, percentage off and percentage discount are identical concepts. Both express the ratio of price reduction relative to the original baseline price.
How do I find the percentage off if I only know the fraction saved?
To convert a fraction saved (like 1/4 off) into a percentage off, divide the top number by the bottom number and multiply by 100. 1 divided by 4 is 0.25, which equals 25% off.
