What Is X% Off? Quick Percent-Off Calculator Table
X% off means you pay price × (1 − X/100). For example, 30% off $50 = $50 × 0.70 = $35 — you save $15. And 20% off $50 = $40. Use the table below for instant answers across common prices and discount levels, then let the app handle any other combination.
Percent Off Reference Table
The table below shows the final price you pay (after the discount is applied) for common original prices across seven discount levels. Savings = original price minus the final price shown.
| Original price | 10% off | 20% off | 25% off | 30% off | 40% off | 50% off | 70% off |
|---|---|---|---|---|---|---|---|
| $10 | $9 | $8 | $7.50 | $7 | $6 | $5 | $3 |
| $15 | $13.50 | $12 | $11.25 | $10.50 | $9 | $7.50 | $4.50 |
| $20 | $18 | $16 | $15 | $14 | $12 | $10 | $6 |
| $25 | $22.50 | $20 | $18.75 | $17.50 | $15 | $12.50 | $7.50 |
| $30 | $27 | $24 | $22.50 | $21 | $18 | $15 | $9 |
| $50 | $45 | $40 | $37.50 | $35 | $30 | $25 | $15 |
| $75 | $67.50 | $60 | $56.25 | $52.50 | $45 | $37.50 | $22.50 |
| $100 | $90 | $80 | $75 | $70 | $60 | $50 | $30 |
| $150 | $135 | $120 | $112.50 | $105 | $90 | $75 | $45 |
| $200 | $180 | $160 | $150 | $140 | $120 | $100 | $60 |
All values are the final price you pay. To find how much you save, subtract the final price from the original. For example, 30% off $100: you pay $70, save $30.
How to Use the Formula
Every cell in the table above was calculated with the same formula: final price = original price × (1 − discount/100). So 25% off $75 means 75 × 0.75 = $56.25. For discounts not in the table — say 35% off $85 — just multiply: 85 × 0.65 = $55.25.
The pattern to remember: the multiplier is always 1 minus the decimal form of the discount. 10% off → ×0.90; 20% off → ×0.80; 30% off → ×0.70; 40% off → ×0.60; 50% off → ×0.50; 70% off → ×0.30.
The table also makes the shape of a sale easy to read at a glance. Move down any single column and you see how the same percentage plays out across price points; move across any single row and you see how a fixed item gets cheaper as the discount deepens. Notice that a 50% off column is simply the original price halved, and a 25% off column is a quarter off — three-quarters of the price remains. These anchor points are worth memorizing, because most store promotions cluster around them, and once you know that 50% off is half and 25% off is a quarter, you can interpolate the rest in your head.
