How It Works & Methodology
A discount is a reduction in the basic price of a good or service. This calculator computes the total money saved, the net discounted price, and the final checkout amount with applicable sales tax.
Calculation Formulas:
- Savings (Discount Amount) = Original Price × (Discount % / 100)
- Discounted Price = Original Price − Savings
- Sales Tax Amount = Discounted Price × (Tax % / 100)
- Final Price = Discounted Price + Sales Tax Amount
Stackable Discounts & Successive Reductions
When retailers offer multiple coupon codes or stacked discounts (such as "20% off storewide plus an extra 10% off with coupon"), the second discount applies to the already discounted amount, not the original price.
For example, on a $100 item, 20% off leaves $80. Taking 10% off $80 subtracts $8, yielding a final price of $72 (a total effective savings of 28%, rather than 30%).
