Splitting the Bills: How Stepfamilies Can Make it Work Without Breaking the Bank (or the Relationship)

Ah, love. It's all fun and games until the bills start rolling in.

And when you're part of a stepfamily, the financial situation can get even more complicated. With kids from different relationships and varying incomes, deciding how to split expenses can feel like an un-solvable math problem.

But fear not! In this post, I’m going to break down some creative ways that stepfamilies who have decided not to fully combine finances can make it work when it comes to sharing certain expenses.

Proportional by Income: If one partner makes significantly more than the other, it can be tough to find a balance. That's where proportional income splitting comes in handy. The idea is simple: each partner contributes a percentage of their income to the household expenses. This approach is helpful when one partner makes significantly more than the other. Let's say you have a couple where one partner makes $70,000 a year, and the other makes $30,000. If they agree to a 70-30 proportional income split, the higher earner would contribute $700 for every $1,000 spent, while the lower earner would contribute $300 for every $1,000 spent. So, if their monthly expenses are $4,000, the higher earner would contribute $2,800, while the lower earner would contribute $1,200. This approach helps ensure that each partner contributes proportionally to their income, which can make things feel more equitable.

50-50: For those who prefer a more straightforward approach, the 50-50 split is a classic choice. Each partner contributes an equal amount to the household expenses, regardless of their income. This can work well if both partners have similar incomes or if they simply prefer an even split. Let's say we have a couple where one partner makes $50,000 a year, and the other makes $45,000. If they agree on a 50-50 split, each partner would contribute $1,250 per month to household expenses. This can work well if both partners have similar incomes, or if they prefer an even split.

By Time in the Home: Splitting expenses based on use is an option when one partner's children spend significantly more time in the household than the other's. For example, let's say you have a couple where one partner has two children who live with them full-time, while the other partner has one child who spends the weekends with them. In this case, the partner with two children would contribute more to the household expenses. They might agree to a 60-40 split, where the partner with two children contributes 60% of the shared expenses, while the partner with one child contributes 40%. This way, the partner with two children pays more because their children are using more of the household's resources.

Splitting expenses in stepfamilies isn't a one-size-fits-all solution. It's important to remember that the way you and your partner split shared expenses might need to be adjusted over time as circumstances change. For example, one partner may see a change in income, or there might be a shift in custody arrangements. However, by remaining open-minded and creative, families can find a system that works for them. Ultimately, the goal should be for both partners to feel that there is an equitable system in place.
