Manufacturer Rebate Net Price Calculator

How it is calculated

The tool subtracts the rebate from the price you pay at the till: net price = P − R and savings % = R ÷ P × 100, where P is the purchase price and R the rebate amount, both in US dollars. P must be above zero and R cannot be negative. If the rebate is larger than the price, it is capped at the price, so the net price shows $0.00 and the saving 100.00%, never a negative price. The calculation ignores sales tax, shipping and the chance that the claim is rejected or arrives late. Rules for rebates, such as deadlines and required proof of purchase, differ by manufacturer.

Common mistakes

• Counting the rebate as an instant discount: the cash leaves your account at full price and may only come back weeks later.
• Comparing the net price with a competitor's sale price without asking whether their price also needs a claim form.
• Missing the claim deadline or a required barcode or receipt, which usually means no rebate and a net price equal to the full price.
• Expecting sales tax to be reduced by the rebate; tax is normally charged on the price at the till, which this tool does not add.
• Entering the rebate as a percentage; the field takes a dollar amount, and 15 means $15, not 15%.
