I'm considering splitting finances with my DH for a number of reasons. I'm thinking mortgage will be 50/50, then all bills and expenses e.g. energy, sky, groceries etc. will be as a proportion of our income. DH earns twice a much as me so he will be 2/3 and I will pay 1/3. Anything outside of this is ours to do as we wish. We intend to have children in the near future, so I imagine all child related costs would fall under the proportion of income section? And should we both be putting away x amount a month for their future (university fees, house deposit) in savings? In addition, should we as a couple be putting away an amount into savings for house repairs and holidays or is this not necessary and it is on us to save it individually and give it as and when it is needed?
