Frequently Asked Questions

How is the discounted price calculated with tax?

First, the discount is subtracted from the original price to find the sale price. Then, sales tax is applied to the discounted sale price, not the original price.

What is the formula for calculating a percentage discount?

Savings = Original Price * (Discount / 100). Final Price = Original Price - Savings.

Can I calculate stacked discounts (e.g. 20% off plus another 10% off)?

For stacked discounts, calculate the first discount, then enter the resulting sale price as the new original price for the second discount.
