The Leakage Calculator

Most hosts have never seen a year of commission as a single figure. Five inputs, one receipt, and nobody asks for your email address.

Not sure? 15% is a fair blended figure. The Commission Table has the details.

Now do something about it

The calculation is kept deliberately simple: revenue × OTA share × commission. It ignores the subtler costs, like guest-side fees inflating your prices, parity clauses capping your own rates, and the guest contact details you never receive. In other words, the real number is worse.
