Percent Off Chart
What every common discount comes to on a $100 item, so a sale sign converts to dollars without arithmetic. Multiply by the price in hundreds for anything else: 30% off $250 is 2.5 times the row for 30%.
Source data and formula checked · How we check
Percent Off Chart reads final price straight off discount, for 12 values from 5 to 75. Every row is computed from the same formula the calculator uses, not measured or copied from another table, so a value between two rows can be worked out the same way. The formula is the one published by NIST Handbook 130.

|---|---|---|
| 5 | $95.00 | $5 |
| 10 | $90.00 | $10 |
| 15 | $85.00 | $15 |
| 20 | $80.00 | $20 |
| 25 | $75.00 | $25 |
| 30 | $70.00 | $30 |
