I thought I'd ask here since I can't seem to wrap my head around how to do this. I'm going through a divorce and attempting to get support payments and whatnot set up in such a way that they are fair.
Basically I need help figuring out a formula where I can take a single fixed payment (€220 in this case, but I will apply it to other payments) and divide it up in such a way that we both contribute proportionally the same.
My ex wife has an income that's 56% of my own. I can't just use the percentage here, because proportionally 44% of 220 is a lot more of her income than it would be of mine, know what I mean? Somehow it has to be calculated using a ratio and not a percentage, and I was too bad in math at school to figure shit out like this.
