How to Calculate a Discount Percentage
Multiply the price by the discount rate, then subtract that from the price. Here's the exact formula the calculator above uses:
Final Price = Original Price − Discount Amount
Convert the %
25% becomes 0.25 (divide by 100).
Multiply
$80 × 0.25 = $20 in savings.
Subtract
$80 − $20 = $60 final price.
Done
Or just use the calculator above — it does this for you.
Finding the Discount % From Two Prices
Already know the original and sale price? Use the reverse formula — this is exactly what the "Find % Off" tab above calculates automatically.
Example: an item was $50, now $35. ($50 − $35) ÷ $50 × 100 = 30% off.

Frequently Asked Questions
How do I calculate a 20% discount?
Multiply the price by 0.20 to get the savings, then subtract that from the price. For a $50 item: $50 × 0.20 = $10 saved, so the final price is $40.
What is the formula for percentage off?
Discount Amount = Original Price × (Discount % ÷ 100). Final Price = Original Price − Discount Amount.
How much is 30% off $50?
30% of $50 is $15, so 30% off $50 is $35.
How do I find the original price before a discount?
Divide the sale price by (1 − discount as a decimal). Example: $60 after a 25% discount → $60 ÷ 0.75 = $80 original price.
