How to calculate rent increase?

To calculate rent increase percentage, subtract your original rent from the new rent amount. Divide that result by the original rent, and then multiply by 100. This figure helps you verify if a rent hike complies with local regulations or lease terms.

Formula

Rent Increase % = ((New Rent − Old Rent) ÷ Old Rent) × 100

Worked Example

Your rent goes from $1,200 to $1,260:

1. Difference: $1,260 − $1,200 = $60
2. Fraction: $60 ÷ $1,200 = 0.05
3. Percentage: 0.05 × 100 = 5%

Result: The rent increased by 5%.
