Common Roommate Money Problems (and How to Avoid Them)

"I always pay first and wait forever for reimbursement"

Use Spllito to track every bill. Share the settlement summary on the first of each month. Set a clear expectation that reimbursements happen within 24-48 hours via mobile payment.

"Someone uses way more electricity / water"

If usage is truly unequal (e.g., one person works from home), discuss a fair premium. You can enter this as a custom split amount in Spllito.

"One person moved in late in the month"

Pro-rate by day. If rent is $900 and someone moved in on the 11th of a 30-day month, they owe $900 ร— (20/30) = $600. Enter this custom amount in Spllito.

"Tracking shared groceries is too complicated"

Add individual grocery trips as separate expenses in Spllito. No need to itemize โ€” just enter the total amount and who paid. Spllito balances everything out.

Frequently Asked Questions

How should rent be split if rooms are different sizes?

The fairest approach is proportional by square footage. Measure each bedroom and calculate each person's percentage of the total bedroom area, then apply that to the monthly rent. Use Spllito to calculate the exact amounts.

Should utilities always be split equally?

For most situations, an equal split is simplest and fair enough. If usage is very unequal (e.g., one person works from home all day), discuss a small adjustment. Track everything in Spllito for transparency.

What if a roommate refuses to pay?

Having a written record is crucial. Using Spllito and sharing monthly summaries creates a paper trail. Keep screenshots of the calculations showing what's owed.

How do I split rent when someone moves in mid-month?

Pro-rate based on the number of days they occupy the space. Enter the prorated amount in Spllito as their share of rent for that month.
