Q: How do roommates fairly split utilities like electricity, gas, and WiFi? What are some common red flags to avoid?
Posted by u/FairBillsNY • 3 hours ago
I'm moving into a 3-bedroom apartment with roommates I met online.
What’s the standard way to split utilities in NYC? And how do I avoid overpaying if someone uses way more electricity or hogs the WiFi?

Splitting utilities sounds simple, but tensions rise when usage is uneven or expectations are unclear. Here’s a guide to doing it fairly—and red flags to avoid.
1. Default Rule: Even Split Unless Agreed Otherwise
Most roommates divide bills—electricity, gas, WiFi—equally by default. This works when all rooms are similarly sized and everyone is home the same amount. But if someone travels 80% of the month or has an A/C running 24/7, it’s fair to discuss adjustments.
2. Use Apps for Transparency
Apps like Splitwise or Venmo Notes let everyone see what’s owed and paid. Avoid verbal-only agreements—write down how you’re dividing each utility.
3. Common Unfair Scenarios
Red flags include: one person never contributing to setup fees, streaming 4K video 24/7 while others only check email, or claiming they don’t use heat but still living in the heated space.
4. Square Footage or Room Premium Adjustments
If one room is much larger or has its own bathroom, you can split utilities and rent proportionally. This can help avoid resentment later. One formula: (room size ÷ total size) × monthly bills.
5. Don’t Forget Seasonal Swings
NYC utility bills fluctuate—heating in winter, A/C in summer. Factor these spikes into your budgeting and have agreements in place about usage.
✨ Quick Summary
- Split equally only if usage is roughly equal
- Use expense-sharing apps for records
- Agree on contributions in writing
- Watch for hidden overuse or freeloading
- Reassess in summer/winter due to spikes
Pro Tip: Add a clause in your roommate agreement about utility rules—this avoids arguments when bills spike mid-lease.
Fair sharing builds trust—and protects your budget.
