Find your ceiling before your competitor does
Run different rental rates through the calculator to see the point where revenue peaks before occupancy starts to drop. Small rate changes across a facility add up fast.

Estimate what every unit could earn
Whether you're running an existing facility or weighing up a new site, the planning question is the same: what will each unit actually earn? Most operators answer it with a spreadsheet, some rough math, and a fair amount of guesswork. This calculator replaces that with a clear estimate built on the real inputs that drive self storage revenue: unit mix, rates and occupancy.
Why it matters
Turn the calculator into a decision-making tool
Optimise your earnings
Better numbers, faster, than a spreadsheet ever gives you
See your revenue potential in one view
Input unit sizes, pricing, occupancy and expenses, and get a clear picture of your income potential, along with practical recommendations to lift it.
Skip the hours of manual spreadsheet work
Manual revenue modelling takes hours and is easy to get wrong. This calculator gives you an accurate financial snapshot in minutes, so the time you save goes toward running the business, not the maths.
Everything that actually drives your income
Four inputs. One clear estimate.
Enter unit types, sizes and rental rates to project annual revenue, then test how a rate increase or added units move the number.
Add monthly costs like rent, utilities, payroll, marketing and repairs to see estimated net income, not just gross revenue.
Break down revenue potential by every unit type you offer, from small closets to garage-sized units, using occupancy and rate by size.
Account for office space, hallways and common areas to see your true rentable square footage and maximum unit capacity.
Getting it right
Three steps to an estimate you can trust
The calculator is only as good as what you put into it. These three steps get you a number worth planning around.
Plug in real numbers
Measure each unit type's square footage and check current rental rates. Pull occupancy over the past 6–12 months for an honest read on demand.
Model a few scenarios
Test different rates and unit mixes to see how each change moves your income. It's the fastest way to make storage unit investing predictable instead of a guess.
Act on what you find
Use the estimate to decide where to adjust rates, which units to reconfigure, or whether a new site pencils out.
FAQs
How accurate are the estimates?
As accurate as the numbers you put in. The model runs on the same inputs used to calculate net operating income, cash flow and annual expenses across the industry: unit mix, rates and occupancy. As a sense check, the average U.S. facility runs at roughly 92% occupancy and a 41% profit margin — use those as a benchmark against your own numbers, not a guarantee.
Do I have to enter every unit to get an estimate?
No. Start with your facility's location, average unit sizes and rates, and you'll get a useful directional estimate. Add unit-by-unit detail later for a more precise number.
How do I use this to actually improve my income, not just measure it?
Run a few rate scenarios through the calculator before you change anything live. You'll see the point where a rate increase adds revenue without pushing occupancy down — that balance is what actually grows income.
Do I need to be a Storeganise customer to use this?
No. The calculator is here to help you plan, whether or not you run your facility on Storeganise.
How is this different from just using a spreadsheet?
A spreadsheet works if you rebuild the formulas correctly every time and remember to update your assumptions. This calculator runs the same revenue and expense logic in seconds, and it's easy to rerun whenever your rates, occupancy or unit mix change.
Can I use this to plan a brand new facility, not just an existing one?
Yes. Enter the unit mix, sizes and rates you're planning, and you'll get a projected income before you commit capital — a fast way to stress-test a new site against realistic occupancy and expense assumptions before you sign a lease.
