How much is 30% off?
A 30% discount means you pay 70% of the original price. On a $100 item, you save $30 and pay $70.
Run the scenario.
The calculator is prefilled with the example above. Change any input and the result updates immediately in your browser.
- Discount amount = original price × discount percentage.
- Final price = original price − discount amount.
- Multiple discounts usually compound rather than simply add.
- Taxes may be applied before or after discounts depending on local rules.
Convert the discount into money
Thirty percent of $100 is $30, so subtracting the discount leaves $70. The same relationship works for any original price.
For quick mental math, paying after 30% off is the same as paying 70% of the original price.
Stacked discounts are different
A 30% discount followed by another 10% discount does not equal 40% off the original price. The second discount applies to the already-reduced price.
