Runs times 365 is the whole ceiling
Every question about a boarding kennel runs into the same wall. You have a fixed number of runs, each of which can be sold once a night, and no amount of marketing sells a run twice. Forty-two runs is 15,330 run-nights a year and that is the top of the business. Everything else is the gap between that number and what you actually sell.
The gap is not spread evenly. Run the defaults and the peak is under a fifth of the calendar but a third of the run-nights, because those are the days you are effectively full. That concentration is why a kennel feels like two businesses stitched together: a capacity-constrained one for nine or ten weeks, and a demand-constrained one for the other forty-two.
Two kinds of labour hour, and they behave differently
Some of the work scales with animals — feeding, cleaning the run, medication, walks, the note that goes to the owner. The rest does not. Somebody opens the building, answers the phone, takes bookings, does the laundry and cleans the common areas whether there are three animals in or thirty. Splitting the two is the most useful thing you can do with a kennel schedule.
Once split, the marginal arithmetic becomes obvious. In a slow week the next animal costs its care minutes and its consumables and nothing else, because the base hours are already there and already paid. In the peak the base hours are saturated and the next animal costs a whole shift, because you cannot add twenty-six minutes of somebody. That is why discounting mid-week in February and holding firm at Thanksgiving are both correct, and why doing it the other way round is a common and expensive mistake.
Occupancy hides inside itself
An annual occupancy figure is an average of a distribution, and the distribution is what you are actually running. Fifty-three percent for the year can mean steady half-full every week, or it can mean full for nine weeks and a third full for the rest. Those are different buildings with different staffing, different cash flow and different answers to whether you should add runs. The three-season split on this page is a blunt instrument, but it is a blunt instrument aimed at the right thing.
The same applies across run types. Occupancy is applied evenly here, and real kennels do not fill evenly — the standard runs go first and the suites are the last to fill and the first to empty. If your pattern is strongly uneven, run each type as its own calculation with its own seasonal occupancy rather than trusting one average.
Adding runs is a peak decision
The natural reading of a capacity ceiling is that raising the ceiling raises revenue. It does, but only on days you were touching the ceiling. A run added to a kennel that turns people away for seventy days a year sells about seventy nights, not 365 times your average occupancy, and it heats, cleans and depreciates for the rest. The extra-run figure on this page deliberately shows the optimistic version and then says so, because the optimistic version is the one that gets used in expansion plans.
The genuinely interesting alternative is usually not more runs but more nights out of the ones you have: longer average stays, better mid-week demand, and add-on services that raise revenue per occupied night without needing another building.
The part that is not arithmetic at all
Animal boarding is a licensed, inspected and heavily insured activity in most places, and what is required varies by state, county and city. Staff-to-animal ratios, run sizes, isolation requirements, vaccination policy, emergency veterinary arrangements and what happens when an animal is injured are all governed by rules and by liability, not by the numbers on this page. The care minutes here are your own operating standard, entered by you. Nothing on this page tells you what your obligations are, and the answer to that question comes from your licensing authority, your insurer and your attorney.

For the payroll side of the labour lines, employee total cost builds the cost of an hour from a wage and your own burden rate. Break-even sales covers the general fixed-cost-and-contribution version if your cost structure is simpler than this. For the days when the phone decides the year, no-shows and deposits puts a number on a cancelled booking, which in a kennel peak is the most expensive kind of empty there is.
If you also run daycare on a slot rather than a night, schedule utilization handles fixed-capacity sessions in the same shape.
Questions people ask
What occupancy does a boarding kennel need?
That depends on your rates, your fixed costs and how much of your labour is base rather than care, which is why this page works it out from your own numbers instead of quoting one. The structure of the answer is always the same: revenue less consumables and care labour is what scales with occupancy, and it has to cover base labour plus everything fixed. Read the break-even section against your current average and, more importantly, against your off-season figure — a kennel that only clears break-even because of nine full weeks is a fragile one.
How do I count care minutes per animal?
Time it rather than estimate it, across an ordinary week and not a quiet one. Include feeding and the prep for it, cleaning the run, medication, walks or yard turnouts, the daily note or photo if you send one, and the handover conversation at pickup spread over the length of the stay. Most people who measure this find it higher than they assumed, because the small interruptions are invisible until they are counted. It matters because it is the number that decides how your staffing scales, and getting it wrong makes the peak look survivable when it is not.
Should I add more runs?
Only if you are turning bookings away, and then only for as many nights as you are turning them away. A new run sells on days you were full and sits idle on days you were not, so the honest calculation uses your peak days and your peak occupancy, not your annual average. The extra-run section here shows the average-occupancy version because that is the version that appears in expansion plans, and then tells you why it is wrong. Construction, licensing, inspection and insurance changes sit on top and are not in the figure at all.
Why does my cost per night go up when I am quiet?
Because most of the cost does not know how quiet you are. The mortgage, the insurance, the base utilities and the hours somebody has to be on site all arrive in full, and they get divided across however many run-nights you sold. Sell fewer and each one carries more. This is the arithmetic behind mid-week and off-season discounting: a night sold at a reduced rate that still clears its care minutes and consumables makes the fixed cost per night lower for every other night too.
Does this tell me how many staff I need?
No. It converts your own care minutes and your own base hours into total hours, which is a scheduling input, not a staffing requirement. What ratios you must maintain, what supervision is required, what qualifications anyone needs and what happens overnight are matters of licensing, insurance and your own duty of care, and they vary by jurisdiction. Animal care also carries real liability that no calculation covers. Take the hours from this page to a schedule, and take the requirements to your licensing authority and your insurer.
