My husband and I have always split all bills 50:50. We have a joint account for all bills and we each pay the same amount into it each month. We use a credit card for all of our day to day expenses (groceries, petrol, gifts etc) and anything we do together (holidays, days out, meals out etc)- it's paid back in full each month and split 50:50. We have a baby now and all baby expenses are shared.
The rest of our money we keep for our individual expenses - mobile phone bills, haircuts, independent socialising, clothes etc. It's always worked well for us and neither of us is particularly better off then the other.
I will be returning to work part time after mat leave. We both want to manage our finances as fairly as possible. My husband is self employed and his income is very variable in amount and erratic in frequency. I cannot work out how we can split things fairly so that I pay a lower proportion of joint bills when we don't know what his income is.
I guess one option is to completely pool our income and expenses, but I am a bigger spender individually and wouldn't want to feel like I am spending more than my fair share. I also keep track of all expenditure and reconcile my transactions - my husband is a bit more relaxed about this!
Any suggestions?
