The Percent Calculator calculates percentage calculations in an instant.
It has 4 calculation options:
1. Find the percentage of a number e.g. calculate 35% of 200
2. Find the percent change between one value and another e.g. calculate the percentage difference between 30 and 45
3. Increase or decrease a number by a percentage e.g. increase 210 by 20% or deduct 20% from 210
4. Find the part percent of a whole e.g. calculate what percent of 250 is 22
The calculator gives you the answer and also the formula used to get the answer, so is great when also teaching children about percentages.
