To find X% of Y, multiply Y by X/100. For example, 15% of 200 = 200 x 0.15 = 30. Our calculator does this instantly when you enter the values.
Divide the part by the whole and multiply by 100. For example, 30 is what percent of 200? 30/200 x 100 = 15%.
Percentage change = ((new value - old value) / old value) x 100. A positive result means an increase, negative means a decrease. Our calculator handles this automatically.
