Modeled shares
Shared cost breakdown
| Person | Move-in share | Monthly share | First-month total | Annual recurring share |
|---|
Formula explanation
Total move-in cost = security deposit + entered one-time fees, setup, moving, and other one-time costs.
Total monthly recurring cost = rent + utilities + internet + parking + renters insurance + other monthly cost.
Equal splits divide totals by the number of people. Percentage shares multiply totals by entered percentages. Custom shares must add to the respective household total within one cent.
Assumptions
- All entered costs describe one fictional household.
- Percentage splits use the same percentage for move-in and monthly totals.
- Annual recurring total equals monthly recurring total × 12.
Limitations
- The tool does not interpret a lease or determine legal responsibility.
- It does not enforce payments, recommend a split, or determine affordability.
- Actual deposits, fees, utilities, and insurance vary.
What this teaches
The breakdown keeps one-time, monthly, first-month, and annual recurring amounts separate and shows how a selected split method changes individual shares.
