How the Airbnb profit calculator works
Updated November 2026
What monthly profit means for a host
A busy calendar can still lose money. Profit is what is left after every cost of the month is paid: the platform fee, the cleaning, and the fixed costs of holding the place. This calculator counts them in that order, so a good month and a busy month stop looking the same.
The formula, in plain words and symbols
Four steps, and the calculator above runs exactly these:
Step 1: stays and money in. stays = nights booked / average stay length. Rental revenue = nights booked x nightly rate. Cleaning fees in = stays x cleaning fee charged. Money in = rental revenue + cleaning fees in. Money is worked out on the exact number of stays, even when it is a fraction; only the stay count on display is rounded.
Step 2: the platform fee. platform fee = fee percent x money in. Airbnb charges its host fee on the booking subtotal, the nightly price plus any fees charged by the host, so the cleaning fee is inside the base. Under the shared split, most hosts pay 3 percent. That is the default here, and the field is editable because fee plans differ.
Step 3: cleaning costs and fixed costs. cleaning costs out = stays x cleaning cost. Monthly profit = money in - platform fee - cleaning costs out - fixed costs. Margin = profit / money in.
Step 4: break-even. Each booked night adds a set amount toward the fixed costs: (nightly rate + cleaning fee / stay length) x (1 - fee percent) - cleaning cost / stay length. Break-even nights = fixed costs / that amount. Break-even occupancy = break-even nights / 30 x 100, using a 30-day month. If one night adds nothing or less than nothing, the place never breaks even at those prices, and the page says so plainly.
A worked example
Take the numbers this calculator opens with. A nightly rate of $120, 18 nights booked, an average stay of 3 nights, a cleaning fee of $60 charged and a cleaning cost of $45 paid, a platform fee of 3 percent, and fixed costs of $900.
Step 1: 18 / 3 gives 6.0 stays. Rent is 18 x $120, which is $2,160.00. Cleaning fees in are 6 x $60, which is $360.00. Money in is $2,520.00. Step 2: the platform fee is 3 percent of $2,520.00, which is $75.60. Step 3: cleaning costs out are 6 x $45, which is $270.00. Profit is $2,520.00 - $75.60 - $270.00 - $900, which is $1,274.40, a margin of 50.6 percent. Step 4: each night adds $120.80 toward the fixed costs, so break-even is $900 / $120.80, which is 7.5 nights, or 24.8 percent of a 30-day month. Change any one input and every one of those numbers moves; that is what the fields above are for.
How to read your result
Profit above zero with a margin of at least 20 percent means the month pays its way with room to spare. Profit above zero under a 20 percent margin means the month works, but thinly: one repair or one slow week can take the profit with it. Profit at or below zero means the month loses money at these prices, and the break-even line shows how many more nights, or what price change, the month needs. A break-even occupancy past 100 percent means the fixed costs cannot be covered in a 30-day month at these prices at all.
What the math takes as given, and what it leaves out
The math holds your rate, your stay length, and your fees steady for the whole month, and it counts one month at a time. It leaves out income tax, local rental taxes and permits, repairs, refunds, and damage claims. Your city may also limit short-term rentals; check your local rules before you count on hosting income. Hosting income also lands unevenly across the year, which is its own budgeting problem: the Kollaz Money guide How to Budget With Irregular Income (Paycheck-First) covers that side in plain words.
The selling side of the same hosting income
Many hosts also sell what they make. The fee math there is different, but the habit is the same: count the platform fee before you call a sale profit. The free Etsy Fee Calculator does that count for a sale.

- Airbnb service fees, Airbnb Help Centre (checked 2026-11-10): under the split fee, most hosts pay a 3 percent service fee, and service fees are a percentage of the nightly price and any fees charged by the host, excluding the guest service fee and taxes. That published base is why this calculator charges the fee on rent plus cleaning fees. The same page describes a single fee paid by the host alone, which is why the fee field here is editable.
