More about the Discount Calculator
Thirty percent off followed by an extra ten percent at checkout doesn't add up to forty percent off total, since that second discount applies to the already-discounted price rather than the original one, which means the two together actually work out closer to thirty-seven percent, a compounding effect that's easy to miscalculate by simply adding the percentages together. This tool calculates sale prices and savings, including stacked discounts applied one after another correctly rather than added together as if they were a single flat percentage. Useful for figuring out the real total discount when a sale percentage and an extra checkout coupon stack together, checking that a store's advertised combined discount actually matches what compounding percentages would produce, or calculating exactly how much a multi-discount purchase actually saves rather than estimating it by simple addition.
