My partner and I recently moved into a rental home in Austin, Texas (US).
Our shared household expenses this month totaled $2,850.00:
- ent: $2,200.00 (paid in full by Partner A from their personal account)
- Groceries: $450.00 (paid in full by Partner B)
- Electric & Internet: $200.00 (paid in full by Partner B)
Our take-home monthly incomes are $6,000 for Partner A and $4,000 for Partner B, so we agreed to split common household expenses proportionally to our net income with weights 60% for Partner A (weight 6) and 40% for Partner B (weight 4), rather than 50/50.
Neither of us has any personal add-ons or adjustments this month.
Can you run the exact two-layer bill split (fair share vs settlement):
1. What is each person's proportional fair share of the $2,850 common pool?
2. Taking into account what each person already paid out of pocket, what is the net settlement—who owes whom how much to square up?
Answer
Partner B owes Partner A **$490.00** to square up.
**Layer 1 — Proportional fair share of $2,850.00**
| Person | Weight | Share | Share % |
| --- | --- | --- | --- |
| Partner A | 6 | $1,710.00 | 60% |
| Partner B | 4 | $1,140.00 | 40% |
**Layer 2 — Net settlement (paid vs share)**
| Person | Paid | Fair share | Net |
| --- | --- | --- | --- |
| Partner A | $2,200.00 | $1,710.00 | +$490.00 (is owed) |
| Partner B | $650.00 | $1,140.00 | −$490.00 (owes) |
Source: this turn's `split_bills.py` ok:true stdout. Weights 6:4 on a $2,850.00 common pool with no adjustments; Partner A paid rent $2,200.00, Partner B paid groceries $450.00 + utilities $200.00 = $650.00.
Want this carried into next month's snapshot, or a one-line Venmo/Zelle note from B to A for $490.00?
