We render apartments for a living. We make the printables we wish renters had.

Meet RbDWithout it, you'll forget half the list.

- One roommate earns twice the other and the lower earner is struggling
- You split furniture costs equally but one person takes it when they move out
- Nobody wants to bring up the money conversation so resentment builds silently

Frequently Asked Questions
Is this really free?
Yes. PDF arrives by email in under five minutes. No credit card.
Does this include utilities?
Yes. The utility split worksheet handles electricity, gas, internet, and streaming. It includes seasonal adjustment so the person near the thermostat does not get stuck with disproportionate heating costs.
What about couples sharing one room?
Model 4 (hybrid) handles this. One couple in one room pays more per person but less per-head than a single occupant with the same square footage.
