250,00What This Calculator Does
A percent-off calculator turns a marked price and a discount into two numbers you actually care about: what you pay and what you save. Type the original price and the percent off, and you get the final price plus the exact amount taken off.
Forward mode: price + percent off → sale price and amount saved.
Reverse mode: sale price + percent off → the original price before the discount.
Every result shows the formula step by step, so the math is easy to check at the register. The discount itself is ordinary percentage math, the same idea behind our percent of a number calculator. For markups, margins, and non-shopping cases, use the general discount calculator.
How Percent-Off Math Works
Two small formulas cover almost every sale sign you will see.
Sale price
Sale Price = Original × (1 − Percent Off ÷ 100)
Amount saved
You Save = Original × (Percent Off ÷ 100)
Worked example: a $80 jacket at 25% off.
You save $80 × 0.25 = $20, so you pay $80 − $20 = $60. The same result comes straight from the sale-price formula: $80 × 0.75 = $60.
Quick Answer: Percent Off Common Prices
The sale price for the most-searched discounts on a few round prices. Read down your discount, across to your price.
| Percent off | $25 | $50 | $100 | $200 |
|---|---|---|---|---|
| 5% off | $23.75 | $47.50 | $95.00 | $190.00 |
| 10% off | $22.50 | $45.00 | $90.00 | $180.00 |
| 15% off | $21.25 | $42.50 | $85.00 | $170.00 |
| 20% off | $20.00 | $40.00 | $80.00 | $160.00 |
| 25% off | $18.75 | $37.50 | $75.00 | $150.00 |
| 30% off | $17.50 | $35.00 | $70.00 | $140.00 |
| 50% off | $12.50 | $25.00 | $50.00 | $100.00 |
| 75% off | $6.25 | $12.50 | $25.00 | $50.00 |

Stacked and Sequential Discounts
Two discounts almost never add up the way the signs suggest. "20% off, then an extra 10% off" is not 30% off. Each discount applies to whatever price is left after the previous one.
Example: a $100 item at 20% off, then 10% off the reduced price.
$100 × 0.80 = $80, then $80 × 0.90 = $72. A flat 30% off would have been $70, so the stacked deal costs $2 more.
To combine two discounts in one step, multiply the factors: 0.80 × 0.90 = 0.72, an effective 28% off. Reversing a chain like this is a job for the reverse percentage calculator.
Percent Off vs Fraction Off
Some stores mark deals as fractions rather than percentages. They are the same discount in different clothes: convert the fraction to a percentage and the math is identical.
- 1/2 off = 50% off
- 1/3 off = 33.3% off
- 1/4 off = 25% off
- 1/5 off = 20% off
To turn a fraction into a percent, divide the top by the bottom and multiply by 100. Planning a night out around a deal? Pair the savings with our tipping on a budget guide so the total still fits.
Percent Off Questions
How do I calculate a percent off?
Multiply the original price by the discount as a decimal to get the savings, then subtract. For 25% off $80: $80 × 0.25 = $20 saved, so you pay $60. Or multiply by (1 − 0.25) = 0.75 in one step.
What is 20% off $50?
$50 × 0.20 = $10 off, leaving a sale price of $40.
How do I find the original price before a discount?
Divide the sale price by (1 − percent off). A $60 price after 25% off means $60 ÷ 0.75 = $80 original. The reverse mode above does this for you.
Do two discounts add together?
No. Stacked discounts apply one after another, so 20% then 10% off equals 28% off overall, not 30%.
Is tax applied before or after the discount?
After. The discount lowers the price first, then sales tax is calculated on the reduced amount.
