Calculation Steps
A percentage discount shows how much cheaper a sale price is compared with the original price. It is a simple way to measure savings on a purchase.
Example: $1200 to $900 is a 25% discount.
What if the sale price is higher?
That produces a negative discount, which is effectively a markup.
Does this accept decimals?
Yes. Any finite real prices are accepted.
Can the original price be zero?
No. Division by zero is not allowed.
Why show percent paid?
It helps compare the final price as a share of the original price.
