What everyone asks
Short answers, with the usual numbers.
Is it better to split 50/50 or by income?
It depends on how close your incomes are. Splitting evenly is the easiest to run, but if one of you earns quite a bit more, the same amount weighs differently: with $1,000 rent, it takes 17.9% of Blue's income and 31.3% of Orange's. By income, the weight is the same for both: 22.7%.
Do we need a joint account?
It isn't required, but it helps keep shared and personal money apart. With a joint account you pay rent, groceries and bills from one place, and each of you keeps the rest as your own.
How much should each of us put into the joint account?
One option is to contribute in proportion to income: with $1,800 of shared costs a month, Blue would put in $1,145 and Orange $655. Another is to put in the same amount if your incomes are similar. What matters is that you both see it as fair.
What if one of us earns a lot less?
Start by talking it through with the numbers in front of you: which costs are shared and how much each one weighs on each income. Splitting by income eases things for the one who earns less, and you can combine it with personal spending money for each of you.
How often should we revisit the split?
When something big changes: an income, the rent, a new expense. In between, a short money meeting every so often is enough so nothing piles up.
Is this financial advice?
No. The guides are general information and the figures are examples with Blue and Orange. For specific legal or tax decisions, talk to a professional.
