Rent Roll Calculator

About this calculator

A rent roll is the standard summary a property owner or manager uses to total the income a rental portfolio actually generates: unit count times average rent gives potential monthly rent at full (100 percent) occupancy, and multiplying that by your actual occupancy rate gives the realistic monthly and annual income the property is really collecting.

Lenders and buyers request a rent roll as one of the first documents in any multifamily or commercial property underwriting process, because the gap between “potential” rent and “actual” rent (driven by vacancy, concessions or non-paying tenants) is exactly what feeds into the property’s economic vacancy rate and, downstream, its net operating income and valuation via a cap rate. Property managers also use a running rent roll internally to track month-to-month income trends and flag units that are underperforming market rent.

Enter your unit count, average rent and occupancy rate, and this calculator totals both your actual rent roll and the full potential rent at 100 percent occupancy, monthly and annually.
