Short-Term Rental Expenses: The True Cost of Running an Airbnb

Direct Answer

Short-term-rental expenses should be built from the property's actual obligations, booking pattern, and vendor quotes. Start with fixed ownership costs, add costs that change with bookings, and reserve for irregular repairs and replacements. There is no reliable national monthly amount or expense ratio that fits every Airbnb.

Keep one-time furniture, equipment, and launch purchases in a separate startup-cost budget. Mixing them into a recurring worksheet makes the property's ongoing cash flow harder to read.

Build a Recurring Expense Worksheet

Use monthly amounts where you have bills. Divide annual costs by 12, and estimate booking-linked costs from the property's expected turnovers and channel mix. Keep financing in the worksheet when you are measuring cash flow, while labeling it separately from property operations.

Fixed obligations

Debt service, property tax, STR-compatible insurance, HOA, permits, internet, baseline utilities, bookkeeping, and recurring software.

Booking-linked costs

Channel fees from payout statements, cleaning and laundry, guest supplies, and any paid management or co-hosting tied to stays or revenue.

Irregular reserves

Repairs, deep cleaning, landscaping or snow service, pest control, appliance and linen replacement, and damage that is not reimbursed.

Property-Specific Worksheet Example

This hypothetical two-bedroom property uses its own bills, quotes, and payout records. It is an example of the worksheet, not a benchmark for another market or home.

The example leaves only a small cushion before income taxes and the owner's unpaid time. A slower month, extra turnover, insurance renewal, or repair can change the result, so replace every row with property evidence and run a downside case before deciding.
