The formula

Gross income

(Rent per unit × units) + other income

Effective income

Gross income × (1 − vacancy%)

Gross potential income assumes every unit is rented at full rate all year — effective income is the more realistic figure once a vacancy assumption is applied.

Other income (parking, storage, laundry, pet rent) is easy to forget when underwriting a deal from a seller’s rent roll — this worksheet gives it its own line.
