How it works

Choose an operation and enter the values. Arabic numerals and Arabic decimal separators are accepted. Discounts show the amount saved and final price; increases show the added amount and total.

Things to know

General arithmetic with results displayed to six decimal places. Values must be nonnegative; discounts must be 0–100%. The base must be greater than zero for ratios or change. Do not include currency symbols or English thousands separators.
