Enter the current cost of rent and the previous cost of rent into the calculator. The calculator will display the percentage increase of rent year over year.

Rent Increase Formula

The following formula is used to calculate the percent increase in rent from year to year.

%R = (RF-RI)/RI *100

  • Where %R is the rent increase percent
  • RF is the current rent
  • RI is the initial rent

Rent Increase Definition

A rent increase is defined as a percentage increase in rent over a certain time period, most often a year.

How to calculate a rent increase?

The following example follows the steps required to calculate the percentage increase a rent has gone up year after year.

First, you need to determine your initial rent cost from the previous year. Depending on what you analyze you can include utilities and other bills in this cost if you want to look at the increase from a total cost of living perspective.

For this example, the initial rent from the previous year was found to be $1000/month.

Next, determine the current cost of rent using the same factors.

In this case, the rent for the current year is found to be $2000/month.

Finally, calculate the percentage rent increase using the formula above:

%R = (RF-RI)/RI *100

%R = ($2000-$1000)/$1000*100

%R = 100% increase

A 100% increase is extremely unlikely for real-world situations, but the process for calculating the increase is the same as above.

What is the most a landlord can raise your rent?

The Tenant is required to pay any additional amounts into the landlord’s account no later than 30 days from publication of a PSA. 

What is an excessive rent increase?

In general, an excessive rent increase is one that is contrary to or grossly disproportionate to the market value of the rental property.
