Markups in Guesty are applied to the listing's nightly rate, base price, and weekend base price, as well as the extra person fee. See the following example to understand how the markup is calculated:
If you add 10% to a 100 USD nightly rate, the price marketed on the booking channel will be 100 x 1.1 = 110 USD. If the resulting price is not a whole number, Guesty will round it up to the nearest whole number. For example, if a 3.5% markup is added to a nightly rate of 51 USD, the resulting price will be 51 x 1.035 = 52.785, and Guesty will round that up to 53 USD.
