It costs 2.5% of your current equus reserve, and caps at 2,500e

From the Breeders manual (at the bottom of the Help Centre page):

Each covering costs between 500 equus and 7,500 equus, unless the stallion is yours.

In addition to that, you will have to pay between 100 equus and 2,500 equus in vet costs, according to your Equus reserve.

please note. 2.5% is wrong. and the minimum is 100e not 500e. the % is rounded up to the nearest 100e

1% of equus, rounded up, minimum 500e maximum 2,500e
