How the Discount Formula Works
The core formula is straightforward: Final Price = Original Price x (1 minus Discount / 100). Rearranging that same equation lets you solve for any of the three variables. When you choose Discount % mode, the calculator divides the price difference by the original price. When you choose Original Price mode, it divides the final price by (1 minus the discount fraction). Multi-item mode applies the same formula per row and sums the results.
Step by Step Example
- A jacket is listed at 120 with a 25% discount.
- Select Final Price mode, enter 120 as the original price and 25 as the discount.
- The calculator shows: Final Price = 90.00, Savings = 30.00, Savings % = 25.00%.
- To compare multiple items, check multi-item mode and enter each item's price and discount.
- The totals row shows combined original cost, total savings, and average discount across all items.
