### The Formula for Calculating Rent Increase in Percent is

\(\text{Rent Increase in Percent} = \left( \frac{\text{New Rent} – \text{Old Rent}}{\text{Old Rent}} \right) \times 100 \)

**Explanation:**

**New Rent:**The amount of the new rent after the increase.**Old Rent:**The amount of the rent before the increase.**Rent Increase in Percent:**The result of the calculation shows how much the rent has increased in percentage terms.

### Formula for Calculating the Rent Increase in Euros

The formula for calculating the new rent based on a percentage increase is:

\(\text{New Rent} = \text{Old Rent} \times \left(1 + \frac{\text{Percentage Increase}}{100}\right)\)

#### Explanation:

**Old Rent:**The amount of the rent before the increase.**Percentage Increase:**The percentage by which the rent is increased.**New Rent:**The amount of the new rent after the increase.

#### Example:

Suppose the old rent is €500, and the rent is to be increased by 10%:

\(\text{New Rent} = 500 \times \left(1 + \frac{10}{100}\right) = 500 \times 1.10 = 550\)

So the new rent is €550.
