Rent Increase Formulas and Equations

1. New Monthly Rent

To calculate the new monthly rent after applying the percentage increase:

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

2. Monthly Increase

To calculate the difference in rent per month:

$\text{Monthly Increase}=\text{New Rent}-\text{Current Rent}$

3. Annual Increase

To find the total increase in rent over 12 months:

$\text{Annual Increase}=\text{Monthly Increase}\times 12$

Example

Let’s say:

• Current Rent = $1,200
• Increase Percentage = 5%
• Lease Term = 12 months

Step-by-step:

New Rent

$\$1,200\times \left(1+\frac{5}{100}\right)=\$1,260$

Monthly Increase

$\$1,260-\$1,200=\$60$

Annual Increase

$\$60\times 12=\$720$

Total Rent

$\$1,260\times 12=\$15,120$

Total Increase Over Lease Term

$\$15,120-(\$1,200\times 12)=\$720$

Final Output:

• New Monthly Rent: $1,260
• Monthly Increase: $60
• Annual Increase: $720
