Frequently Asked Questions
How do I calculate a discount?
Multiply the original price by the discount percent divided by 100, then subtract from the original price. A 25% discount on $120 saves $30, so you pay $90.
How do I find the original price from a sale price?
Divide the sale price by (1 − discount as a decimal). If you paid $90 at 25% off, the original was $90 ÷ 0.75 = $120.
Do stacked discounts add up directly?
No. A 20% discount followed by another 10% is not 30% off — it is 28% off, because the second discount applies to the already-reduced price.
Does sales tax apply before or after the discount?
In most US states, sales tax is calculated on the discounted (actual selling) price, not the original list price.
