📖 Overview
Use this upgraded calculator when people consume different amounts and equal split is unfair.
⚙️ How It Works
This splits total cost by weighted participation rather than equal headcount.
The Formula
Person Share = Total × (Person Weight ÷ Sum of All Weights)
| Weight | Relative participation unit for each person (any positive number) |
| Total Cost | Full amount to be divided among all participants |
💡Weights can represent anything: hours used, rooms occupied, items ordered. The key is agreeing the weighting scheme before splitting — not after seeing the total.
Quick Reference
| Person | Weight | Share % (of total 7) | $210 bill |
|---|---|---|---|
| Person A | 3 | 42.9% | $90 |
| Person B | 2 | 28.6% | $60 |
| Person C | 2 | 28.6% | $60 |
| Total | 7 | 100% | $210 |
Practical Tips
💡 Use this when consumption is uneven.
💡 Agree weighting method upfront to avoid disputes.
