FAQ
What is a stacked discount?
A stacked discount applies a second discount to the already reduced price (e.g., 20% + 10% off does not equal 30% off, but rather 28% off of the original retail cost).

Does tax apply before or after discounts?
In standard retail operations, sales taxes are calculated on the final discounted price, saving you tax money. This tool calculates this sequence automatically.
