How to stop arguing about bills with your roommates
Living with people means splitting costs. Rent, electricity, groceries, the Wi-Fi bill, whoever grabbed toilet paper last. Most households handle this with Venmo requests and memory, which works until someone forgets they owe $40 from three weeks ago and now it's awkward.
Splitwise keeps a running tab of who owes what. You log expenses as they happen and the app does the math.
Get the app
Download Splitwise from the App Store or Google Play. There's also a web version at splitwise.com. Make an account with your email or Google login.
The free tier limits you to 5 expenses per day and shows ads. For a household of two or three people that's probably fine. Pro costs $40/year and adds receipt scanning, unlimited expenses, and no ads.
Create a group
Tap the plus icon and make a group. Call it whatever. "Apartment" works. Add your roommates by email or phone number. They'll need to install the app too.
You can have multiple groups. If you travel with some of the same people, make a separate one for the trip so those expenses don't bleed into your rent ledger.
Add an expense
Somebody pays the electric bill. They open the app, tap "Add expense," type "Electric - April" and the amount. Splitwise splits it evenly across everyone in the group by default. Three people, $150 bill, each person owes $50, and the one who paid gets credited.
If the split isn't even, tap "split options" and choose by percentage, by shares, or by exact amounts. Useful when one roommate has the bigger bedroom and pays more rent.
Recurring bills
Rent is the same every month. So is internet. Instead of logging it 12 times, set it as recurring. Add it once, pick the interval, and Splitwise creates it on schedule going forward.
Groceries
This one gets messy because not everyone eats the same stuff. Honestly the easiest approach is to just log shared grocery runs as a group expense and split evenly. Yes, you don't drink oat milk. It roughly evens out over months and nobody has to stand in the kitchen itemizing a receipt.
If your household really cares about accuracy, Pro has an itemization feature where you can assign individual items on a receipt to specific people. More precise, more tedious.
Settling up
After a month or two, balances pile up. Person A owes Person B $85, Person B owes Person C $30. Splitwise simplifies this automatically and tells you the minimum number of transfers to zero everyone out.
When you actually send the money (Venmo, Zelle, cash, whatever), go back into Splitwise and tap "Settle up" so the balance resets. The app doesn't move money itself.
Why it actually helps
The thing that makes this work isn't the app. It's that everyone can see the same numbers. There's no "I thought you paid last time" because the history is right there. The conversations about money get shorter because there's nothing to argue about.
I'd skip it if you live with one other person and just alternate who pays. With three or more people and uneven expenses, it removes a surprising amount of household tension.
