Maintenance Reserve: How Much Per Booking to Set Aside

The reserve isn't a savings habit. It's a per-booking number you can justify from your own repair history.

Last updated: September 23, 2026

Every host eventually faces that month. The boiler goes, the mattress has had enough, and the cost lands on the same statement as that month's income. The reserve exists so that month is boring.

The problem isn't deciding to save. It's deciding how much. And the usual answer — a percentage of revenue — is a number borrowed from somebody else's building.

This guide explains why that starting point fails. It builds the figure from three cost bands and the replacement cycle of each. It shows where the money sits so a quiet month doesn't spend it. And it sets out a yearly review that adjusts the number without rebuilding the calculation.

Key Takeaways

• Percentage is borrowed arithmetic. Your unit's failure pattern isn't the average of anybody else's.
• Three bands, not one pot. Soft consumables, wear parts and major items fail on different clocks.
• Lifespan does the work. Cost divided by expected years is the whole formula.
• Per booking means divided by bookings. The annual figure only becomes a habit once it's attached to a stay.
• Review once a year. Change the inputs that changed; leave the structure alone.

Why a percentage of revenue is the wrong starting point

A percentage feels authoritative because it's specific, and it's wrong for two reasons that compound.

First, it ties the reserve to price rather than to wear. Two units at the same nightly rate can have entirely different cost profiles. One is a studio with a sofa bed and a shower. The other is a two-bedroom with a washing machine, a dishwasher and a balcony full of furniture. The rate is the same; the list of things that will fail isn't. A reserve set on price systematically underfunds the second unit and overfunds the first.

Second, it moves when it shouldn't. In a strong year your revenue rises and so does your reserve, even though nothing in the unit has changed. In a weak year the reserve shrinks at exactly the moment you have more empty nights to absorb a repair with. The number should be driven by what's in the room, not by what the room earned.

What to use instead is replacement arithmetic. Every item in a unit has a purchase cost and a life. Divide one by the other and the item tells you what it costs you per year. Add them up and the unit tells you what it costs to keep whole. Divide by the stays you expect and you have a per-booking figure you can explain to anybody — including yourself, six months later, when the temptation arrives to treat it as profit.

That last property is the real argument. A percentage is a number you hope is right; a replacement-cycle figure is one you can defend line by line, because every input is an invoice you've already paid.

Building the number from replacement cycles

Three bands, because three different clocks are running in the same room. The following lifespans are illustrative placeholders to show the method; replace every one with your own experience and invoices.

Band one: soft consumables. Linen, towels, pillows, duvets, mattress protectors, kitchenware, glassware. These are replaced in sets rather than individually, and they're the band most often forgotten because nothing ever "breaks" — it just stops being presentable. Worked example: a linen programme of four sets at $120 each, replaced every two years, costs $240 a year. Kitchenware at $200 replaced every three years costs about $67 a year. Band total: roughly $307.

Band two: wear parts. Shower heads, tap cartridges, bulbs, appliance filters, door furniture, small appliance replacement — the things a weekly walk-through finds. These fail unpredictably in timing but predictably in aggregate, which is why they belong in a reserve rather than in a budget you set each month. Worked example: an appliance at $450 expected to last six years costs $75 a year; filters, bulbs and small fittings at $180 a year, replaced as they arise; a mid-cycle replacement of one small appliance at $250 every four years costs about $63. Band total: roughly $318.

Band three: cyclical major items. Mattress, sofa, water heater, flooring, repainting, the white goods themselves. These are the items that turn a bad month into a bad year, and they're exactly the ones a percentage never covers, because they arrive infrequently and land heavily. Worked example: a mattress at $700 replaced every eight years costs about $88 a year; a sofa at $1,100 over ten years costs $110; a water heater at $900 over twelve years costs $75; repainting and flooring at $2,200 every seven years costs about $314. Band total: roughly $587.

Now put the three together and divide.

• Annual total. $307 + $318 + $587 = about $1,212 a year for this unit.
• Expected bookings. Say thirty-five stays a year in this unit.
• Per-booking reserve. $1,212 ÷ 35 = roughly $35 per booking.

Two adjustments are worth making deliberately.

If your unit is new, band three is small for the first few years and grows later. So either phase the major items in by their age, or hold the full figure from the start and let the surplus build. Holding the full figure is simpler, and it front-loads the money you'll need in year seven.

And if a band is dominated by one item, split that item out and give it its own line. A single $2,200 entry silently decides your whole number.

Where the reserve sits so it survives a slow month

The most common failure of a reserve isn't the calculation. It's the account. Money held in the same place as operating income gets spent as operating income, and the month it gets spent is usually the month you needed it.

Three properties decide whether it survives:

• A separate account, in the name of the property rather than the person. One unit, one reserve, and the balance reads as an obligation rather than as a bonus.
• A transfer that happens on the booking, not on the mood. If the $35 moves when the stay is confirmed, it never depends on anybody remembering. If it moves "when there is spare cash", it won't move in the months that matter.
• A floor you don't cross for convenience. Decide what the balance is for — say, enough to cover the largest single line in band three — and treat anything under it as unavailable for anything except maintenance.

The account also answers a question that otherwise gets argued every time: is this money profit. It isn't. It's a liability you've already incurred by owning a mattress, and the only question is whether you recognise it now or in year eight.

Where the reserve meets the calendar, the practical question is simple: which stays are actually going to happen? A per-booking figure only works if it's attached to a real booking count. Availability and rates for Airbnb, Booking.com, Agoda and Trip.com sit on one grid at localsbnb.com, which is the easiest place to read the year's shape before you divide.

Reviewing the number once a year without rebuilding it

The reserve should change when the unit changes, not when the month changes. Once a year, take the list and alter only the lines that have actually moved:

1. Mark what failed this year. Anything you paid for that wasn't on the list goes on it, with its real cost. This is the step that makes next year's number better than this year's.

2. Correct the lifespans that were wrong. If the sofa lasted six years rather than ten, the line was understated. Adjusting the lifespan is more honest than adjusting the amount, because it keeps the method intact.

3. Re-divide by the bookings you now expect. Occupancy changes, and the per-booking figure has to follow it, or the annual total is never reached.

4. Leave everything else alone. Resist the urge to re-derive the whole thing. The value of the calculation is that it's comparable year to year, and rebuilding it destroys the comparison.

FAQ

Is there a standard percentage I should use?

No, and treat any figure quoted as one as somebody else's building. Your unit's own list of things that will fail is a better input than any average, and it takes about an hour to write down.

What if I have never tracked a repair before?

Start from what you can see: walk the unit and list everything with a cost and a plausible life. Your first number will be rough and it'll still be better than a guess, because the yearly review corrects it.

Should the reserve cover damage caused by a guest?

Separately. Guest-caused damage is a claim against a deposit or a resolution process, not a maintenance event. Mixing the two makes both numbers unreadable.

A reserve you can defend line by line is the difference between a bad month and a bad year. Write the list once, annualise it, divide by the stays you actually expect, and let the yearly review sharpen it. If you want the booking count at the bottom of that division to be the real one, put the year on one calendar at localsbnb.com.
