Consumables cost per stay: the line every host forgets to budget

My cleaner's invoice was $55 a turnover and I had it memorized to the dollar. What I never wrote down was the $12 of toilet paper, coffee, soap, and trash bags that walked out the door with every guest — until I added it up across a year and found a $2,600 line I'd been treating as a rounding error. Consumables are the cheapest single thing in your operation and the easiest to quietly bleed on, because no individual restock ever feels big enough to track.

This post is the math on that line: what each turnover actually consumes, why it costs the same whether the guest stays two nights or seven, and the difference between buying it right and buying it in a panic at the corner shop on a Friday.

What counts as a consumable — and what doesn't

A consumable is anything a guest uses up or takes that you replace at the next turnover. That's a narrower category than "stuff I buy for the listing", and getting the boundary right is what stops you from double-counting your costs.

Three things are not consumables, even though new hosts lump them in:

• Linen and towels are durable inventory with a wear curve, not a per-stay spend. You amortize them over hundreds of washes, not one stay — that's a different calculation entirely, covered in linen inventory for short-term rentals.
• Cleaning chemicals — the spray, the toilet brush, the mop heads — usually belong to your cleaner, baked into their per-turnover rate. If you're supplying them, that's part of the cleaner pay conversation, not your consumables budget.
• Hardware — light bulbs, batteries, a replacement shower squeegee — is maintenance, and it belongs in your maintenance reserve, not here. It's irregular, not per-stay.

What's left — the true consumables — splits into two buckets. Bathroom: toilet paper, hand soap, shampoo, conditioner, body wash, facial tissue. Kitchen and living: coffee, tea, dish soap, dishwasher tablets, a fresh sponge, trash bags, paper towels, and the pantry basics (salt, pepper, oil, sugar) that a guest expects to find. That list is the entire line item, and it's remarkably consistent across markets — a roll of toilet paper does the same job in Lisbon as in Lyon.

The per-stay breakdown, item by item

Here's a realistic turnover for a one-bedroom, priced at 2026 bulk unit costs — what you pay per unit when you buy the warehouse pack, not the four-roll emergency pack. "Per stay" is what one average guest consumes or pockets before the next changeover.

That's the floor, and it assumes refillable dispensers and bulk buying. Swap in single-use toiletry bottles, leave a welcome basket with snacks, and stock branded coffee, and the same 1BR runs $13–15 a stay without anything feeling extravagant. A studio with a galley kitchen lands closer to $6; a 3BR that sleeps eight runs $20+ because eight people burn through toilet paper and coffee at a rate one couple never will.

The number isn't the point — yours will differ. The point is that it's a real $8–15, every single turnover, and almost nobody has it written down next to the $55 cleaner invoice they recite from memory.

Why consumables are a per-stay cost, not a per-night one

Here's the trap that makes this line bigger than it looks: roughly 70% of your consumables cost is per-stay, not per-night.

When a guest checks out, you don't top up a half-used roll of toilet paper or pour the leftover coffee back in the bag. You reset to a clean starter set — fresh rolls, a full soap dispenser, a sealed sponge, a new packet of coffees — because the next guest expects to walk into a stocked unit, not your previous guest's leftovers. That reset costs the same whether the departing guest stayed two nights or seven.

Only about 30% of the line scales with length of stay: the marginal coffee a long guest drinks on day five, the extra rolls a week-long family gets through. So a 2-night stay and a 7-night stay cost you nearly the same in supplies — which means short stays are expensive per night on this line, the same way they're expensive on cleaning. This is exactly the per-stay-versus-per-night split that decides your floor price; the full treatment is in break-even nightly rate math, and consumables are one of its line items.

Then there's the graze effect. Guests don't ration a bar of soap or count out coffee pods — they take the whole travel-size shampoo, brew four cups a day, and occasionally pack the unopened ones for the road. You're not budgeting for what a reasonable person uses; you're budgeting for what an average guest takes, and those are different numbers. Stocking single-use toiletry bottles makes this worse: a guest who'd never pour out your refillable dispenser will happily pocket three little bottles.

Bulk vs retail: where the real money leaks

The per-item costs above assume you bought right. The leak isn't the supplies — it's how you buy them.

Buy your toilet paper in a 30-roll pack and your coffee by the case, and the table-one total holds. Restock from the shop around the corner because you ran out, and you're paying 50–75% more on every line — plus the single most expensive item on this whole page, which isn't on either table: the emergency run.

When the cupboard hits empty mid-changeover, someone has to fix it before the guest arrives, and that someone is either you or your cleaner. A cleaner who drives to a shop, buys what's missing, and brings the receipt charges a supply-run surcharge of $25–45 on top of the retail-price supplies. Do that twice in a month and the surcharges alone exceed your entire bulk consumables budget for the listing. If you run it yourself, it's an hour of your time and a tank's worth of fuel to deliver a $4 pack of toilet paper. The supplies are cheap. Running out of them is not.

Three occupancy scenarios, annualized

The per-stay number feels trivial. Annualize it and it stops feeling trivial. Take a steady $11-per-stay 1BR across three turnover rates:

The high-turn row hides a second effect. A studio doing 22 stays a month is running short bookings, which means more of those 70%-per-stay starter sets per night occupied — so its effective consumables cost per night is higher than the long-stay listing's, even at the same per-stay number. Short-stay, high-turnover listings get hit twice: more turnovers, and a higher fixed-cost share on each one.

Across a three-listing portfolio at steady occupancy, that's nearly $4,800 a year you're spending whether you tracked it or not. It won't bankrupt you. But it's the same order of magnitude as a maintenance reserve you'd never dream of ignoring — and unlike the reserve, it leaves the account in $11 increments you never notice.

What to stock — the starter-set principle

The instinct, once you realize guests notice supplies, is to over-stock. That's the wrong correction. The right frame is the starter set: leave the minimum that protects the review, not a household's monthly shop.

What a guest actually expects on arrival is small and specific: enough toilet paper to start (two to three rolls, plus a visible spare so nobody has to ask), hand soap at every sink, a basic shampoo and body wash in the shower, dish soap and a clean sponge in the kitchen, a couple of trash bags, and a few coffees and teas. Hit those and your reviews never mention supplies. Miss the toilet paper and you'll read about it in a one-star headline.

Three traps to avoid:

• The full pantry. A cupboard stocked with oil, spices, condiments, and snacks reads generous and gets raided. You're not running a grocery; you're protecting a review. Basics, not a shop.
• Premium single-use toiletries. The little branded bottles cost three to five times a refillable dispenser per use, and they're the most-pocketed item in the unit. Wall-mounted refillable dispensers cut both the cost and the theft, and read as cleaner and more sustainable to the exact guest who'd dock you for plastic waste.
• Individually-wrapping everything. Sealed-for-hygiene packaging on every item triples your unit cost and your trash output. Reserve it for the things guests actually expect sealed — toilet paper, a new sponge — and skip it on the rest.

The starter-set principle is also why "can I just charge a consumables fee?" is the wrong question. You can't itemize it to the guest — it lives inside your cleaning fee and your nightly rate, which is the whole reason it has to be small enough to disappear there. (How the cleaning fee itself should be structured is its own decision: cleaning fee vs all-in pricing.)

The stockout costs more than the supplies

Everything above is a rounding error next to the failure mode this line actually creates: the stockout. A guest who finds an empty toilet-paper holder at 11pm writes a different review than one who found a stocked unit, and that review costs you far more than a year of bulk supplies. The supplies are insurance against the stockout; the supplies are not the expense.

So treat consumables the way you treat linen — as inventory with a reorder point, not as a thing you buy when you remember. Pick a par level (say, four spare rolls of toilet paper, two refill jugs of soap, a sleeve of coffee per listing), set a trigger ("when the cupboard hits one spare, reorder the bulk pack"), and put the restock decision on a schedule instead of a memory. The hosts who never run out aren't more diligent — they took the decision out of their own hands.

That's also the part that quietly breaks at scale. One listing, you eyeball the cupboard. Three listings on three different turnover rates, and "did the studio get restocked after last week's four back-to-back checkouts?" becomes a question you can't answer from memory — which is exactly the kind of per-listing operational state RentTools is built to track for free, alongside the calendar that tells you how many turnovers are about to hit each unit. The supplies are cheap. Knowing which cupboard is about to be empty is the part worth automating.

One opinionated take

Consumables are the most under-managed line in short-term-rental operating costs precisely because each instance is so small. Nobody writes down a $4 pack of toilet paper, so nobody notices it's a four-figure annual line per listing — or that it's the line most likely to generate the review that costs a month of bookings. Buy in bulk, stock the starter set and not the household shop, switch to refillable dispensers, and put the restock on a reorder point instead of your memory. Do that and the line shrinks to its true size: cheap insurance against the one failure mode — the empty cupboard on a Friday — that costs orders of magnitude more than the supplies ever will.
