Gender Age
16–25 26––30 31–35 36–40 41–45 46–50 51–60 61–70 70+
Male 100% 100% 100% 90% 80% 80% 70% 60% 50%
Female 100% 90% 70% 50% 33% x x x x

male(incl. bonus) + wife (incl bonus) / 2 = x% per try
evry born child, reduces wife fertilty by 5 %
seducing adds 25 %
bonusses and malusses are in the tooltips

So my female caracter has 32y (70%) and -50 fertility of a trait, my husband has 46y (80) and +30 from trait.

So would be (0.2 + 1.1) / 2 = 0.75

I'm doing it right?

I saw another formula that's similar but it multiplies the fertility of the couple per 4.75 before /2.

Don't know what's correct or not

EDIT: oooh and they are soulmates, does it change anything?

soulmates didnt change anything I think, but they gain the + 25 % from beeing in love. Multiplie with 4.75?

Yeah some ck3 site I came by multiplied your formula by 4.75 before /2, found it strange too.

They were lovers before being soulmates so they prob have the 25% buff.

50/50 either happens or it doesnt
