Calculation of the percentage of a base value and a given interest rate

The percentage calculator calculates the percent value of a starting or base amount and a percentage.

For example, what is the percentage value if the base amount is 200 and the percentage is 15%.? The percentage value is 15%.

Percentage value

Value after addition

Value after deduction

Basic Value

The starting or base value.

Percentage

the percentage of the difference between the surcharge or discount on the base value.

This example calculates an increase of 3 percent.

The percentage is given by \(P = 3\). the basic value is given with \(B = 1000\)

We are looking for the percentage \(V\).

Die Formel lautet \(\displaystyle V=\frac{B·P}{100}=\frac{1000 · 3}{100}=30\)

The 30 will be added to the basic value. So \(30 + 1000 = 1030 \) is the future value.
