Calculator for Plus-Minus Percent

If to a value x percent is added and then x percent of the new value is subtracted, the result is lower than the initial value. Also if subtracted first and then added, the value will be lower, the result is identical in both cases.

± % is .

This is % of the initial value.

Example: if to 200 30% is added, you get 260. If from 260 30% is subtracted, the result is 182. This is 91 percent of the initial value.
If from 200 30% is subtracted, you get 140. Add 30 % to 140 to get 182 again.
