Frequently Asked Questions
How are stacked or double discounts calculated?
A stacked discount applies the second percentage to the already discounted price, not the original price (e.g. $100 with 20% off becomes $80; an additional 10% off $80 becomes $72, resulting in an effective 28% total discount).
How does sales tax affect discounted items?
In most jurisdictions, sales tax is applied to the final discounted purchase price rather than the original MSRP.
Can I calculate fixed dollar discounts instead of percentages?
You can enter fixed prices and compare the effective percentage difference using our Percentage Calculator.
