Splitting expenses is a often a touchy topic when you’re living with a significant other, roommates or family.
If everyone doesn’t agree it can get pretty nasty fast.
There are a few ways to split expenses between yourself and those you live with but I’m going to highlight four of the most common ways today.
Splitting expenses really isn’t an issue if you’re living with your significant other, husband or wife and have combined finances.
However, a lot of people keep separate finances when they’re dating (as we did) and some continue this after they get married (we did not).
Want to know how my wife and I used to split our expenses when we were dating? Make sure you read through to the end of the post.
Split Expenses Equally
Splitting expenses equally is the easiest method to calculate because all you do is simply divide the expense by however many people will be paying for it. While it is easy to calculate, that doesn’t mean it is going to be a popular decision.
This method can work well for items that get equal use such as parking. It seems to work well for spouses or significant others living together because it is simple and doesn’t require a lot of thought.
It doesn’t always work as well for roommates or family living together though because use of the item being paid for is not always used equally by everyone.
Split Expenses Based on Usage
Splitting expenses based on usage makes a lot of sense from a practical standpoint but it doesn’t always sit well with the people you share living space with. It can also be extremely difficult to calculate.
This method is great when you have roommates. I had two roommates in a three bedroom apartment once and we used this method often. The bedroom sizes in the apartment were not equal so it didn’t make sense to split the rent equally.
Another expense this worked well for was our cable bill. We each had different cable receivers in our bedrooms. The receivers had different costs so we split the cable bill based on each individual roommate’s use.
This didn’t work for food expenses because we couldn’t measure consumption accurately. Instead we all bought our own groceries and asked if we wanted to use some of our roommate’s food.
We couldn’t split the electricity bill based on usage either but I think the only reason we didn’t do this because we couldn’t have individual meters on all of our outlets! I’m joking… only to a point. One of my roommates probably would have liked splitting the electric bill based on usage.
Split Expenses Based on Income
Splitting expenses based on income seems to be popular among spouses and significant others. Incomes can be very different in some relationships and some people feel it is fair to split expenses based on the ratio of income between the people living together.
For instance, if a boyfriend and girlfriend who lived together made $25,000 and $75,000 respectively then shared expenses would be paid 25% by the boyfriend and 75% by the girlfriend. Bills like rent, utilities, and groceries can all be easily split this way.
This might not make as much sense if you are splitting bills with roommates but could work if you’re living with multiple generations of family.
It could cause some arguments when it comes to expenses that are solely for one person. For instance, if a couple each owns their own cars and drove their car exclusively it might not make much sense to split that expense according to income.
If you use some common sense and only split expenses that are actually shared this might work out for your situation.
Contribute What You Can
The method of contributing what you can is normally what ends up happening when family is forced to live together or a spouse or roommate loses a job.
It takes a very generous person (the person paying the bigger share) and an honest person (the person contributing what they can) to make this work without resentment.
This is rarely a planned method of splitting expenses and it requires a lot of effort by both parties. Normally this works best if you set some ground rules.
If a person is just contributing what they can, any spending that isn’t paid toward shared expenses can cause an argument.
If a person hasn’t contributed to rent but instead purchased a new piece of jewelry arguments could be right around the corner.
How We Split Our Expenses
We have split our expenses a few different ways over the years. We changed our methods based on what made the most sense for us at the time.
When we were dating and both in college I’d pay for our dates (for the most part) and we’d each pay for our own gas to visit each other since we went to different colleges. We split our expenses equally during this time period.
I then graduated from college and was working full time while my then girlfriend remained in college. During this time I paid for most of the expenses and my girlfriend would pay for some smaller expenses because she was contributing what she could.
I’d often pay her for her gas money to come visit so it wouldn’t add to her student loans. During this time period we used the contribute what you can method.
Before we were married, but when we were both in the same place and lived together we split our expenses equally. We didn’t make the same amount of money but we felt this is the best way to split the expenses at this time.
We had a very low total cost in regards to shared bills, partially thanks to our townhouse we bought on a whim, and could both handle the amount of expense without any financial difficulty at the time.
We kept our finances separate since we weren’t married. However, splitting expenses is no longer an issue because we got married and we now combine our finances!
