SELF-STORAGE RATE MANAGEMENT
Operators ask this as a question about the percentage — 8%, 12%, 20% — and it is really a question about move-outs. Any increase is worth sending if it survives the churn it causes, and the reason so many are sent too small is that the churn is priced wrong: a departing tenant is counted at their rent, as though the unit sits empty for the rest of the year. It does not. It re-lets at your street rate, which on a long-tenured unit is usually above what the leaver was paying.
This page works one increase all the way through. The self-storage rate increase calculator does the same arithmetic on your own numbers, in your browser, with nothing uploaded.
Open the calculatorA single facility, one cohort of 42 units of the same size, all at an in-place rent of $118 a month. The street rate for that size today is $149. Tenant protection and other per-unit income runs $12 a month on an occupied unit. When a unit turns over it sits empty 45 days, the replacement tenant gets the usual free first month, and the turn — clean-out, lock, listing, admin — costs $45. Over the next twelve months about 22% of this cohort would move out whatever you do.
The proposal is a 15% increase: $118 to $135.70, or $17.70 more per unit per month.
Start with the figure the decision is usually made on. A tenant paying the raised rent is worth $1,772 over twelve months once the $12 of ancillary income is counted. That is the number in an operator’s head when the increase letters go out, and it is not what a move-out costs.
What a move-out costs is that value minus what the unit earns after it is re-let, which comes to four terms:
| Term | Amount |
|---|---|
| Rent and ancillary lost over 45 days empty | $238 |
| Free first month for the replacement tenant | $149 |
| Turn: clean-out, lock, listing, admin | $45 |
| Re-rent at $149 street instead of their $135.70 | -$160 |
| What one induced move-out costs | $272 |
$272, not $1,772. The fourth line is the one that does the work and the one no rule of thumb carries: the replacement pays more than the person who left, for every month of the horizon, and that credit cancels most of the downtime. It is also the line that reverses when the raised rent goes above street, which is the single most important thing to know before deciding how far to push a long-tenured cohort.
With a move-out costing $272 and every staying tenant paying $17.70 more for twelve months, the increase is worth $6,272 across the cohort over the horizon — and it would still be worth exactly nothing only if it drove out 60.8% of the group, or about 25 of the 42 units, on top of the 22% who were leaving anyway. If it caused no extra move-outs at all it would be worth $6,958, so even a heavy response takes a surprisingly small bite.
Put that next to what an operator would actually expect from a $17.70 increase — two or three units — and the decision stops being close. The value of the calculation is not that it says yes; it is that it converts an unanswerable question (how many will leave?) into an answerable one (would twenty-five of them leave?).
| Increase | New rent | Break-even move-outs | Worth over 12 months |
|---|---|---|---|
| 5% | $123.90 | 42.2% | $1,990 |
| 8% | $127.44 | 51.0% | $3,274 |
| 10% | $129.80 | 54.8% | $4,131 |
| 12% | $132.16 | 57.6% | $4,987 |
| 15% | $135.70 | 60.8% | $6,272 |
| 20% | $141.60 | 64.4% | $8,413 |
| 25% | $147.50 | 66.7% | $10,554 |
The last column holds the move-out response constant, which is the assumption to be suspicious of: a 25% increase does not provoke the same churn a 5% one does. That is why this table names no best row. What it does show is the shape of the trade — the tolerance for move-outs widens as the increase grows, because everyone who stays is paying more — and it shows where the cohort would cross its own street rate, which is where the arithmetic changes character rather than degree.
The honest answer is that the size of the increase is not what decides it — the cost of the move-outs it causes is, and that cost is far smaller than it looks whenever the unit re-rents above the leaver’s rent. On the worked example above, 42 units at $118 raised 15% to $135.70 against a $149 street rate, the increase is worth $6,272 over twelve months and would only stop paying if it drove 60.8% of the group out, on top of ordinary churn. That is 25 of 42 units. The number to argue about is not the 15%; it is whether you believe 25 people would leave over $17.70 a month.
Because the unit does not stay empty. Price a move-out at the departing tenant’s rent and you are assuming the space earns nothing for the rest of the year, which is only true if you never re-let it. What you actually give up is the gap between keeping them and re-letting: the rent lost during lease-up, the move-in concession the replacement gets, and the turn cost — minus the difference between your street rate and what the leaver was paying. On the example that comes to $272 rather than $1,772, and the last term is a credit of $160 rather than a cost.
The credit becomes a charge, and the arithmetic turns. Below street, losing a tenant hands you a unit you re-let for more than they were paying. Above street, you lose the tenant and re-let for less, so the same move-out costs the downtime, the concession, the turn and the rate difference. The break-even move-out rate falls accordingly, and it falls fastest exactly where operators are most tempted — on long-tenured tenants whose rents have been raised several times already.
Not in practice, and the table above is deliberately not a recommendation. Arithmetically a larger increase collects more from everyone who stays, so it can absorb a higher move-out rate: on this example 5% breaks even at 42.2% churn and 25% breaks even at 66.7%. What that table cannot know is how much churn each increase actually provokes, which is a fact about your tenants and your market, not about the arithmetic. Read each row as a question — would more than this share walk? — and stop at the last row you can answer yes to.
Compare the group you raised against a group you did not, over the same window, from your own management software. Move-outs in the 60 to 90 days after a notice, minus the move-out rate of an unraised group of similar size and tenure, is the induced rate this calculator asks for. Two increases measured that way are worth more than any published benchmark, because tenure mix and local vacancy differ so widely between facilities that a national average tells you almost nothing about yours.
No. It is arithmetic on figures you supply. It makes no determination about what your lease or your state’s self-storage act permits, what notice a tenant is owed before an increase takes effect, or whether raising rent is right for your business. Verify every figure against your own records and a qualified professional before acting on it.
