About Discount Calculator
Discount Calculator works out the final price after a percentage discount, the amount saved in dollars, and the implied percentage off when you only know the original and sale prices. It is the everyday tool for sale shopping, comparing offers, and figuring out whether a coupon is actually worth using.
Worked example: an $80 jacket with 25% off costs $60 — you save $20. Conversely, if a $50 item is reduced to $32, the implied discount is 36%. The calculator handles both directions, so you can answer either 'what will I pay?' or 'how good a deal is this?' from whichever pair of numbers you have in front of you.
Two patterns come up often. Stacked discounts do not simply add — a '30% off followed by an extra 10%' is not 40% off, it is 1 − (0.7 × 0.9) = 37% off. Multiplicative discounts always come out below the sum, which retailers occasionally exploit in coupon wording. Percentage discounts and dollar-off coupons also interact differently with tax: a percentage discount is typically applied to the pre-tax price (and tax then computed on the smaller amount), while a fixed-dollar manufacturer coupon is often applied after tax. Knowing which is which can swing the final price by a few percent.
