About this tool
Updated
Discount percentage versus cash saving
A percentage discount depends on the original price, so the same rate can produce a different cash saving on each item.
For example, 10% saves $5 from $50 but $20 from $200. Compare the final price as well as the advertised percentage.
What this calculator does not include
The result excludes tax, delivery, coupons, finance charges and store-specific rounding rules.
Use the retailer's checkout total for a purchase decision. This tool is a quick arithmetic check, not a price guarantee or financial recommendation. A second percentage discount normally applies to the reduced price, not the original price, so separate offers should be calculated one step at a time. Currency symbols are deliberately omitted because the same formula works for any currency. Return policies, product exclusions and minimum-spend conditions are also outside the calculation.
