Gross Potential Rent (GPR) Calculator

What gross potential rent (GPR) measures

Gross potential rent is the rent your portfolio would collect if every unit were leased at market rent for the full year. It's a ceiling, not a forecast. Real rent collected is always lower because of physical vacancy (units sitting empty) and loss-to-lease (units rented below market). The two combined determine economic occupancy.

Economic occupancy vs physical occupancy

Physical occupancy is the percent of units that are occupied (9 of 10 = 90 percent). Economic occupancy is the percent of GPR you actually collect (which factors in both vacancy AND below-market rents). Economic occupancy is always equal to or less than physical occupancy. Most operators track only physical and miss the loss-to-lease story.

What healthy looks like

For SFR portfolios, healthy economic occupancy runs 92 to 97 percent. Above 97 percent often signals very tight operations or under-rented units that are about to lose tenants. Below 92 percent is a leak, usually from below-market rents that have built up over multiple renewals without catch-up increases.

How to reduce loss-to-lease

Three levers. First, audit every unit's actual rent against current market rent. Second, plan a sequence of catch-up increases at upcoming renewals (3 to 5 percent per renewal is rarely disruptive). Third, use renewal forecasting tools (like Shuk's Lease Indication Tool) to start renewal conversations 5 to 6 months out, when there's still time to negotiate the rent component.

How to use this calculator

Enter total units, occupied units, average actual rent (across occupied units), and average market rent (across all units). The calculator returns annual GPR, actual annual rent collected, economic occupancy, and loss-to-lease in dollars and percent.

Frequently asked questions

What is gross potential rent (GPR)?

Gross potential rent is the total rent a portfolio would collect if every unit were leased at market rent for the full year. It is a ceiling number. Actual rent collected is always lower because of physical vacancy and loss-to-lease (units rented below market).

How do you calculate economic occupancy?

Economic occupancy equals actual annual rent collected divided by gross potential rent, expressed as a percent. It factors in both physical vacancy AND below-market rents. Most operators track physical occupancy (occupied units / total units) and miss the loss-to-lease component.

What is loss-to-lease?

Loss-to-lease is the gap between gross potential rent (every unit at market) and current rent roll (actual rents on the leases in place). It is the dollar amount you're leaving on the table because tenants are paying below current market rent. Typical SFR loss-to-lease runs 3 to 8 percent.

What is a good economic occupancy for SFR rentals?

For SFR portfolios, healthy economic occupancy runs 92 to 97 percent. Above 97 percent is excellent. Below 92 percent suggests either physical vacancy issues or material loss-to-lease that should be addressed at the next renewal cycle.

How do you reduce loss-to-lease?

Audit every unit's actual rent against current market rent. Plan a sequence of catch-up increases at upcoming renewals (3 to 5 percent per renewal is rarely disruptive). Use renewal forecasting to start renewal conversations 5 to 6 months out, when there is still time to negotiate the rent component.
