How do I calculate a discounted price?
Multiply the original price by (1 minus the discount as a decimal). A 25 percent discount on $80 means 80 times 0.75, which equals $60. The calculator does this automatically: enter the original price and the discount percentage, and it shows both the final price and the dollar amount you saved.
What is the difference between percent off and percent of?
A 30 percent off discount means you pay 70 percent of the price. A 30 percent of the price is the discount amount itself. They sound similar but mean opposite things. The calculator uses the standard "percent off" convention because that is how stores advertise sales.
How do I stack two discounts correctly?
Stacked discounts apply one after the other, not added together. A 20 percent then 10 percent discount is not 30 percent off; it is 28 percent off, because the second discount applies to the already-reduced price. Run the calculator twice: once with the first discount, then feed the result back in with the second.
Can I work backwards from a sale price to find the discount?
Yes. If you know the original and final prices, the discount percent equals (original minus final) divided by original, times 100. Enter both prices and the calculator shows the implied discount. This is useful for checking whether an advertised "50 percent off" is real or just marketing on an inflated original price.
Does the calculator handle tax on discounted items?
No, it focuses purely on the discount math. Sales tax is normally applied to the discounted price, not the original. To get the final out-the-door price, take the discounted result and run it through the sales tax calculator separately. Combining the two in one step would only confuse the breakdown.
What is a markdown vs a markup?
A markdown is a discount taken off a higher price. A markup is the amount added to a wholesale cost to get the retail price. Stores often mark items up by 100 percent then mark them down 50 percent, so the "sale" price equals the original cost. The discount calculator handles markdowns; markups are a different formula.
