Short-term rental expenses: a monthly checklist for hosts
Why a monthly check beats a year-end scramble
Most hosts find out how much their property actually earned only after the platform posts its annual summary, months after the money moved. By then it is hard to remember which repair quote you paid in March or whether that software subscription was still active in June.
A ten-minute monthly pass through your expenses turns a vague sense of "I think I'm making money" into a concrete number: payouts in, costs out, profit left over. You catch overspending while it is still small, and the annual total assembles itself from twelve clean months instead of one chaotic pile.
The checklist: one line per category
Each month, go through these categories and make sure every expense you paid falls under exactly one of them:
- Cleaning – the cost of each turnover, whether you pay a service or do it yourself with labour factored in.
- Supplies – toiletries, linens replacement, coffee, welcome items, anything consumed by guests between cleanings.
- Utilities – electricity, gas, water, and any usage-based charges tied to the property.
- Internet – the monthly broadband or hotspot bill allocated to the rental.
- Insurance – your landlord or short-term-rental policy premium for the month.
- Repairs and maintenance – fixing a leaky tap, replacing a broken hinge, seasonal servicing. Small fixes go here; if a repair is capital in nature, note it separately.
- Software and subscriptions – booking-channel tools, guest-messaging apps, cleaning-scheduler software, any SaaS you pay for to run the listing.
- Mortgage or rent – the fixed housing cost: mortgage principal and interest, or the rent you pay if you are a subletting host.
If an expense does not fit neatly, pick the closest category and add a short note. Consistency matters more than perfection at this stage.
Example numbers
The table below shows one example month so you can see how the arithmetic works. These figures are illustrative only; your own numbers will differ.
| Item | Amount |
|---|---|
| Payouts received | $3,200.00 |
| Cleaning | $560.00 |
| Supplies | $95.00 |
| Utilities | $210.00 |
| Internet | $60.00 |
| Insurance | $120.00 |
| Repairs and maintenance | $75.00 |
| Software and subscriptions | $30.00 |
| Mortgage or rent | $1,450.00 |
| Total expenses | $2,600.00 |
| Net profit | $600.00 |
| Margin | 18.8% |
The margin is simply net profit divided by payouts received. It tells you what share of the money that came in actually stayed with you after every listed cost.
A 15-minute monthly routine
Set a recurring reminder for the same day each month – say, the first weekend – and follow three steps:
- Save receipts. File every receipt or invoice into one folder (a cloud drive works well). Name files by date and category so you can find them later without digging.
- Match payouts against the platform's payout report. Open your booking platform's payout history for the month and confirm the total matches what actually landed in your bank account. Note any holds or adjustments.
- Record each expense under one category. Enter every payment from step 1 into your tracking sheet, choosing exactly one checklist category per line. At the end of the fifteen minutes you will have a clean monthly table with a total, a net profit, and a margin – the same shape as the example above.
Do this for twelve months and your annual picture writes itself: sum the twelve totals, divide by twelve for an average month, and spot any category that is quietly growing.
This is general bookkeeping math, not tax or financial advice.
The STR Host Profit Tracker does this arithmetic for one short-term rental: enter your own numbers and it shows annual net income, cash-on-cash return and cap rate.
