How this calculator works
The discount is subtracted from the original price first. Optional sales tax is then applied to the discounted subtotal.
Worked example
A 25% discount on $120 saves $30 and produces a $90 sale price before tax.
Frequently asked questions
Is tax calculated before or after the discount?
This calculator applies tax after the discount, which is common for retail sales.
Can a discount exceed 100%?
No. The supported range is 0% through 100%.
Does this support multiple stacked discounts?
Not directly. Apply the first discount, then use its sale price as the next original price.
