Five Self-Storage KPIs to Check Each Morning

Most operators check one number with their coffee, and it's occupancy. It's the number your manager quotes and the one brokers ask about. It's also the easiest number in this business to hit while losing money.

Below are the five numbers worth checking every morning, and the mistake that each one can hide.

1. Economic occupancy

Say physical occupancy is 95%. Now run a second calculation. Take what you collected last month and divide it by what you'd collect if every unit were rented at today's street rate. That result is economic occupancy. Say it comes back at 75% while physical occupancy sits at 95%. Then the facility is full of discounts, stale rates, and tenants who stopped paying around March.

The two numbers drift apart slowly, so nobody notices a 20-point gap the day it appears. It builds with each $10 move-in special and each skipped rate increase until the chart looks like this:

2. Revenue per available square foot

The second check is revenue per available square foot (RevPASF), which is total revenue divided by total rentable footage. Once you own two facilities, you can't compare them on occupancy. A site full of 5x5s and a site full of 10x30s will never have comparable occupancy, but dollars per foot means the same thing at both.

The mistake here is comparing against nothing. A 2% rise in RevPASF looks good until you learn the three competitors down the road raised street rates 8%. Now you're the cheap option, which attracts the tenants who show up in the next number.

3. Delinquency by bucket

Delinquency is the third check, and the blended number is where it goes wrong. "4% delinquent" sounds healthy. Split it into 30/60/90-day buckets and you might find the 30-day bucket doubled in six weeks. Meanwhile old 90-day write-offs rolled out and pulled the average down. A rising 30-day bucket means collections is slipping weeks before the lien letters start. Keep the blended figure under 5% if you want a round target, but watch the buckets.

4. Acquisition cost per move-in

The fourth number is what each move-in costs you. Marketing spend is the obvious part, and people tend to skip the rest. A move-in special is money you chose not to collect. Staff time on the phone counts, and so does the aggregator fee when the lead came through one. Add it up for each channel. Some operators find that walk-in traffic is their cheapest source of tenants by a factor of five. Their paid channel is filling units that would have rented anyway within nine days.

The mistake is measuring acquisition cost without looking at who you acquired, which is what the last number covers.

5. Length of stay

A tenant who takes your $1 move-in special and leaves after three months may have cost you money. A tenant who stays 26 months covers almost any acquisition cost. Break length of stay down by unit size and by channel. If a promotion keeps bringing in three-month tenants, it's mostly generating turnover costs.

Each of these numbers covers a gap in the one before it. Occupancy doesn't show revenue, and revenue means little without a market comparison. The blended delinquency rate hides which way it's moving. Acquisition cost needs retention data next to it. Check all five together each morning.

Most operators skip the market comparison because rate data has usually been sold as its own product and priced per market. StorageFlow includes it in the platform at no extra charge.
