How to read the chart
| Price | 10% | 20% | 30% | 40% | 50% | 60% | 70% | 80% | 90% |
|---|---|---|---|---|---|---|---|---|---|
| $10 | $9 | $8 | $7 | $6 | $5 | $4 | $3 | $2 | $1 |
| $20 | $18 | $16 | $14 | $12 | $10 | $8 | $6 | $4 | $2 |
| $50 | $45 | $40 | $35 | $30 | $25 | $20 | $15 | $10 | $5 |
| $100 | $90 | $80 | $70 | $60 | $50 | $40 | $30 | $20 | $10 |
| $200 | $180 | $160 | $140 | $120 | $100 | $80 | $60 | $40 | $20 |
| $500 | $450 | $400 | $350 | $300 | $250 | $200 | $150 | $100 | $50 |
| $1,000 | $900 | $800 | $700 | $600 | $500 | $400 | $300 | $200 | $100 |
Example: 20% off $60 → find the $60 row's 20% column: $48.00.
Two discounts?
This chart is for a single discount. Two in a row — "30% off, plus an extra 20% off" — don't add up; they multiply, landing at 44% total rather than 50%. The two-discounts-in-a-row walkthrough has the formula and worked examples.

Sale price vs sticker price
One caution before you trust any discount figure: the percent only means something if the original price is real. Seasonal events are the classic case — some "50% off" tags ride on prices marked up for the occasion. The pre-event price-rise check shows how to spot an inflated anchor, and the dollar-off vs percent-off comparison covers which coupon type wins at your price.
