About the Handiwork Discount Calculator
The Discount Calculator works out the final price after a percentage off and shows exactly how much you save. Enter the original price and discount to see the sale price instantly, add a second stacked discount for "extra % off" promotions, and optionally include sales tax to get the real out-the-door total.
How to use the Handiwork Discount Calculator
- Enter the original price and the discount percentage.
- Optionally add a second discount and a sales tax rate.
- Read the final price and your total savings.
How stacked discounts work
Stacked discounts apply one after another, not added together. A 20% discount followed by an extra 10% off is not 30% off — the second discount applies to the already-reduced price, giving 28% off overall. The calculator handles this correctly so you know the true final price before tax.
Discount then tax
Sales tax is normally calculated on the discounted price, not the original. The calculator applies your discounts first, then adds tax to the reduced amount, matching how most checkouts work so the final total reflects what you will actually pay.
Frequently asked questions
How do I calculate a percentage discount?
Multiply the original price by the discount percentage to get the savings, then subtract it from the original price. The calculator does this instantly and also shows the amount saved.
Are two stacked discounts the same as adding them?
No. Stacked discounts apply in sequence, so 20% then 10% equals 28% off overall, not 30%. The calculator computes the correct compounded result.
Is tax applied before or after the discount?
After. The calculator discounts the price first, then applies sales tax to the reduced amount, which is how most retailers calculate the final total.
