Want this to run itself every month?
ExpenDiv tracks each person's share and sends payment reminder emails on the due date. Your roommates just tap the link and pay. No account required on their end.
Example: 4 roommates, 5 bills
Alex, Jordan, Sam, and Casey share a house. Their monthly bills:
•
Rent: $3,200 (all 4 people equally → $800 each)
•
Electricity: $120 (all 4 equally → $30 each)
•
Internet: $80 (Alex and Jordan only → $40 each)
•
Netflix: $22 (Sam and Casey only → $11 each)
•
Spotify: $16 (all 4 equally → $4 each)
Monthly totals: Alex $874, Jordan $874, Sam $845, Casey $845.
One-time summary vs. ongoing tracking
This tool gives you a snapshot for any given month. If you want to skip re-entering everything each month, ExpenDiv handles the ongoing tracking -- it remembers each person's share, sends email reminders on the due date with your payment link, and records who paid. Your roommates never need to download anything or create an account.
Frequently Asked Questions
How do I split multiple bills between roommates?
List every shared bill, assign each person their exact portion, and total it up per person. This calculator handles that math for you and lets you export the result to share with your household.
What if one person pays more for some bills than others?
Use custom amounts for each bill. Assign each person exactly what they owe per bill, whether that's equal, proportional, or fully on one person. The summary adds it all up automatically.
Can I save this and share it with my roommates?
Yes. Download as CSV for a spreadsheet you can open in Excel or Google Sheets, or use Print / Save PDF for a clean, shareable document. Both include a full per-person and per-bill breakdown.
How do I stop chasing roommates for payment every month?
ExpenDiv sends automated email reminders on the billing date with a payment link already in the email. Your roommates click the link and pay. You never have to ask. Free to try.
Can I split some bills equally and others by custom amount?
Yes. Each bill is independent. Use 'Split equally' for bills everyone shares evenly, and enter custom amounts for bills where roommates pay different shares -- for example, a streaming service only two people use.
What if a bill is only shared between some roommates?
When you expand a bill, just check off the people who share it. Anyone not selected is excluded from that bill entirely. The summary only counts each person for the bills they are part of.
What is the difference between this tool and the ExpenDiv app?
This tool gives you a one-time calculation. ExpenDiv is a full bill tracker -- it remembers each person's share month to month, sends automatic reminders with your payment link, and logs who has paid. No re-entry required each month.
