## Calculate percentage

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.
