Frequently asked questions

How is the discounted price calculated?

The listed price minus the percentage share of that price: 20% off a 50 dollar item removes 10, leaving 40. The calculator applies the reduction to the original tag price only. A quick mental trick: 10% off means paying 90 percent, so any result equals the price times its remaining share.

Can I stack two discounts here?

Run the calculator twice instead. Two 20% reductions compound rather than add: 20% off an already-20%-reduced 100 gives 64, not 60, because the second cut applies to the lower amount.

Does the discount apply to the tax or before it?

Store discounts normally reduce the pre-tax subtotal, and that is what this tool returns. Tax added afterwards applies to the lower figure — the order of operations is reduce first, tax last.
