Frequently asked questions
Does this calculator include sales tax?
No. It calculates the discount and sale price based only on the original price and discount percentage you enter. Add tax separately if needed.
Can I use this for percentage math unrelated to shopping?
Yes. The percentage calculation mode works for any two numbers, such as figuring out grades, ratios, or general percentage changes.
Is there a limit to the price or percentage I can enter?
No practical limit — the tool performs standard numeric calculations on whatever values you provide.
Is my pricing data stored anywhere?
No. Everything is calculated locally in your browser and nothing is saved or transmitted.
