About this tool
A “30% off” sign is only useful if you know the final number. Type the original price and the discount percentage and this calculator shows the sale price and exactly how much you save, add your sales tax rate and you'll see the true total you'd pay at the register, since tax is correctly applied to the discounted price.
The results update live as you adjust the numbers, so you can compare deals in seconds: is 25% off $80 better than 40% off $60? The savings figure makes the answer obvious without any mental arithmetic.
