OTA commissions explained: the real cost of each channel

Ask ten operators what an OTA costs them and most will quote a percentage. That number is real, but it is only the start. Between the rate a guest pays and the money that lands in your bank account sit payment fees, cancellations, promotions and a few costs nobody puts on the contract. This article walks through OTA commissions from the headline rate to the real cost, so you can compare channels fairly.

How OTA commissions work

Commission is the fee a channel keeps for delivering a booking. The models differ more than most people expect.

Percentage commission

The most common model. The channel takes a fixed share of the booking value, and the share is usually higher in competitive cities or when you join visibility programs. What counts as "booking value" matters: some channels calculate commission on the room rate only, others include extras, cleaning fees or taxes.

Net rate model

You give the channel a net rate and it sells at whatever price it chooses, keeping the difference. This is common with wholesalers and some package sellers. It can be simple to manage, but you lose control of the public price, which can create parity problems.

Agency model versus merchant model

In the agency model, the guest pays you directly, at the property or through your own payment setup, and the channel invoices you for the commission later. You control the payment, but you also carry the risk of no-shows and chargebacks.

In the merchant model, the channel collects the payment from the guest and sends you the net amount, sometimes weeks after checkout. Cash flow is slower, but the channel absorbs part of the payment risk.

Many large channels now let you choose or mix both, which makes the comparison less obvious.

What the commission includes and what it does not

A commission typically covers listing, advertising, search placement and the booking itself. It does not usually cover:

• Payment processing, when you collect the money yourself
• Currency conversion, when guests pay in a different currency
• Extra visibility programs or "preferred partner" tiers
• Discounts you fund through channel promotions
• The cost of handling guest messages, modifications and disputes

Each of these is small on its own. Together they can add several points to the real cost of a channel.

Hidden costs to watch

Payment fees

Under the agency model, you process the card yourself and pay your own processing fees. Under the merchant model, some channels charge a separate payment fee on top of the commission. Either way, moving the money is not free, and it is often forgotten in the comparison.

Cancellations

Flexible policies convert better on OTAs, so many properties offer them. The cost appears later: cancelled nights that could have been sold, and on some channels, commission that is still charged if the guest was a no-show and you did not report it in time.

Virtual cards

Some channels pay properties with a virtual credit card that becomes active on the day of arrival. The card has to be charged manually or through your payment system, and it carries the usual card processing fee. Cards that are never charged, or charged late, are a quiet source of lost revenue.

Promotions and discounts

Mobile rates, early booking deals, last minute deals and member pricing are often opt-in, but the discount comes out of your rate while the commission is still calculated on the original price. Check the fine print before enabling anything.

Chargebacks and disputes

Under the agency model, a guest dispute is your problem. The time spent on it, and the occasional lost case, is a real cost.

How to calculate the real cost of a channel

Take one typical booking and follow the money.

• Start with the price the guest paid.
• Subtract the commission, calculated the way the channel actually calculates it.
• Subtract any payment or currency fees.
• Subtract the discount you funded, if the booking used a promotion.
• Estimate the cancellation effect: multiply by the share of bookings on that channel that actually arrive.
• Compare the result with the same booking made through your own website, where you pay processing fees but no commission.

Do this for each channel with a month of real data. The ranking of channels by real cost is often different from the ranking by headline commission, and that is exactly the point.

A central system that stores reservations, payments and channel fees in one place makes this calculation a report instead of a spreadsheet project.

When a high-commission channel is still worth it

A high cost per booking is not automatically a bad deal. A channel can earn its commission when:

• It fills dates you consistently struggle to sell, such as low season or midweek
• It brings guests from a market you cannot reach any other way
• It delivers longer stays or higher average spend, so the commission is spread over more revenue
• The alternative is an empty room, which costs you the full rate

The trap is paying a high commission for guests who would have booked directly, or on a cheaper channel. That is why the goal is not the lowest commission but the best net result across the whole mix.
