Self-storage management fee calculator

What one store pays its manager in a month and in a year, which of the two fee terms is doing the work, and the revenue at which that changes.

It is the figure an owner needs for a budget line and the figure a manager needs for a proposal. Both read the same arithmetic.

Four lines, from three inputs:

Take the example values, $60,000 of monthly revenue, a fee of 6 percent and a $3,000 minimum. The percentage produces $3,600, above the minimum, so it applies: $3,600 a month and $43,200 a year, an effective rate of 6 percent. The minimum would bind below $50,000.

• Monthly fee: the revenue the fee is charged on, times the fee rate, or the monthly minimum, whichever is greater.
• Annual fee: the monthly fee, times twelve.
• Effective rate: the annual fee, divided by twelve times the monthly revenue.
• Crossover revenue: the monthly minimum, divided by the fee rate.

The arithmetic is exact. What it is applied to is the part worth checking twice.

• Gross receipts, collected revenue and effective gross income are three different numbers from the same store, and the difference shows in a delinquent month. Use the base the contract names.
• What sits inside that base varies: late fees, protection plan commission, retail, truck rental and admin fees are in some agreements and out of others.
• Only the base fee is priced here. Incentive fees, construction or capital project fees, call center and marketing charges, and any technology line are separate terms.
• Twelve times one month assumes flat revenue. Storage is seasonal, so a store near the crossover should be run month by month.
• The three values on the page are placeholders chosen to show the arithmetic. Replace all three.

Which term binds is the whole story at a small or lease-up store. Below the crossover the owner pays the same dollars at $49,000 of revenue as at $30,000, and the effective rate climbs as revenue falls: a $3,000 minimum on $30,000 of revenue is 10 percent, not 6.

That makes the crossover a date, not just a number. In a lease-up it is the month the fee starts tracking performance instead of acting as a fixed cost, and it belongs in the absorption schedule.

A store that straddles it pays both ways across a year. At a $50,000 crossover, $52,000 in summer is charged on the percentage and $48,000 in winter on the minimum, so annualizing either month alone misstates the year.

The fee is a cost, not a verdict on the manager. For the year ahead it belongs in a budget as a share of effective gross income, which is how Verillum AI carries it in a store budget built from that store’s own actuals. A demo will show one.
