How to Calculate Co-Host Commission and Owner Payouts (Without Spreadsheets)

Every co-host does the same calculation at the end of the month: what did the property earn, what is my commission, what did I spend, and how much do I send the owner? Get it wrong once and the owner starts checking every line.

This guide walks through the calculation with a worked example, the choices you must agree with the owner first, and how to stop doing it by hand.

Step 1: Agree how your commission is calculated

Before any numbers, the agreement with the owner has to answer three questions:

• Percentage or fixed? A percentage of booking income (for example 20%) or a fixed monthly fee (for example €150).
• Percentage of what? Income after channel fees is the most common base, because it is the money that actually arrives. Some agreements use gross booking value; whichever you choose, write it down.
• Who pays which costs? Cleaning, laundry, consumables, repairs, utilities. Costs you pay are reimbursed from the income; costs the owner pays directly are not.

Step 2: Collect one month of data per property

For each property you manage you need:

• the income from every booking in the month, from every channel;
• every expense in the month, with who paid it.

Step 3: Do the calculation

The settlement is:

Owner payout = income − your commission − expenses you paid

Worked example

A two-bedroom apartment in October. Your fee is 20% of income. Income from Airbnb and Booking.com, after channel fees: €2,400.

Your income is the €480 commission; the €400 you spent comes back to you through the deductions. The community fees are shown so the owner sees the full picture, but they are not deducted again: that money never went through you.

With a fixed fee of €150 instead, the payout would be €2,400 − €150 − €400 = €1,850.

Step 4: Present it so the owner can check it

A good statement lists the lines above for each property and ends with one number: the transfer. If the owner can recompute the payout from the page, you will get far fewer questions.

Why spreadsheets make this harder than it is

The formula is simple. What takes time is feeding it: copying payouts from each channel, matching receipts to properties, remembering which bills the owner paid, and keeping a separate copy for every owner. The risk is not the arithmetic but a missing row.

How to automate the calculation

To automate it, the software needs to know three things you set up once: which properties you manage, the fee on each, and who paid each expense. Then the monthly calculation is just reading the data.

This is exactly how Hostfinn works. For each managed property you set a percentage or fixed monthly fee. Expenses are recorded against the property with who paid them. At month end Hostfinn applies income − your fee − expenses you paid for every property of an owner and produces a PIN-protected report the owner opens in any browser, then prints or saves as PDF. The same fee calculation feeds your own dashboard, so your income and the owner's payout always agree.

With the Professional and Corporate plans, bookings arrive automatically from Airbnb, Booking.com and Vrbo through calendar sync; on Basic you record income yourself. Plans start at €9.90/month, with a 14-day free trial and no setup fee — see plans and pricing.

Frequently asked questions

Is co-host commission calculated on gross or net booking income?

Either can be agreed. Net of channel fees is more common because it matches the money received. The important part is writing the base into the agreement and applying it the same way every month.

What if a guest cancels after I paid for cleaning?

Keep the cleaning as an expense you paid; it is deducted from that month's income like any other cost you covered, unless your agreement says otherwise.

Can I charge different commissions to different owners?

Yes. Commission is set per property, so each owner — and each property — can have its own terms.
