Common Discount Quick Reference
| Discount | $50 Item | $100 Item | $500 Item |
|---|
| 10% off | $45 | $90 | $450 |
| 20% off | $40 | $80 | $400 |
| 25% off | $37.50 | $75 | $375 |
| 30% off | $35 | $70 | $350 |
| 50% off | $25 | $50 | $250 |
| 70% off | $15 | $30 | $150 |
💡 Double discount trap: 20% off then 10% off is NOT 30% off. It's 28% off. Sequential discounts always give less than the sum suggests. Use the calculator to check.
Frequently Asked Questions
How do I calculate price after a discount?
Multiply the original price by (1 − discount%/100). Example: $200 with 25% off = $200 × 0.75 = $150. The % Off tab does this instantly.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount%/100). Example: item costs $75 after 25% off. Original = $75 ÷ 0.75 = $100. Use the "Find Original" tab.
How do I calculate what percentage discount I got?
((Original − Sale Price) ÷ Original) × 100. Example: Was $80, now $60. Discount = ((80−60) ÷ 80) × 100 = 25% off. Use the "What % Off?" tab.
Is 20% off then 10% off the same as 30% off?
No. Sequential discounts don't add up. 20% off then 10% off = 0.80 × 0.90 = 0.72, meaning 28% total discount — not 30%. Always calculate each step separately.
How much do I save with 20% off a $150 item?
$150 × 20% = $30 savings. You pay $120. Use the calculator above for any price and percentage instantly.
What is a good discount percentage?
10–20% is a standard sale. 25–30% is a good deal. 50%+ is a clearance or major sale event. Anything above 70% is usually end-of-season clearance or loss-leader pricing.
