Occupancy explained: physical vs economic

Physical occupancy is the share of rented units or square metres. Economic occupancy is actual rental revenue as a percentage of revenue at full occupancy at street rate. A facility can be 92% physically occupied and only 81% economically, for example because of discounts and arrears.

Physical occupancy

Physical occupancy = rented units ÷ total units × 100%. You can also calculate it in square metres: rented m² ÷ total rentable m² × 100%. The second measure is fairer when your units vary a lot in size.

Economic occupancy

Economic occupancy = actual rental revenue ÷ potential rental revenue × 100%. Potential revenue is what you would earn if every unit were rented at street rate. Discounts, lower prices on old contracts and unpaid rent pull economic occupancy down.

Worked example

A facility with 200 units, of which 184 are rented:

MeasureValue
Physical occupancy184 ÷ 200 = 92%
Potential revenue per month (all rented at street rate)€30,000
Actual revenue per month€24,300
Economic occupancy€24,300 ÷ €30,000 = 81%

Why you should track both

High physical occupancy with low economic occupancy often means you discount too much or that old contracts sit far below street rate. Lower physical occupancy with high economic occupancy can actually be healthy. Only by tracking both can you tell whether price increases or promotions make sense.

Frequently asked questions

What is a good occupancy rate for self-storage?

It depends on the facility's age, the market and your pricing strategy. So do not look at the percentage alone, but at physical and economic occupancy together and at the trend per unit size.
