{primary_keyword} Formula and Mathematical Explanation
The {primary_keyword} uses a weighted ratio for rent and an equal ratio for utilities. First, sum all room weights. Second, divide total rent by the weight sum to find rent-per-weight. Third, multiply by your room weight to get your weighted rent portion. Utilities remain equal per roommate. The {primary_keyword} blends these results into one total.
Step-by-step derivation
- Total weight = Your Weight + (Roommates − 1) × Other Average Weight.
- Rent per weight unit = Total Rent ÷ Total Weight.
- Your rent share = Rent per weight unit × Your Weight.
- Utility share = Utilities ÷ Roommates.
- Total due to you = Your rent share + Utility share.
| Variable | Meaning | Unit | Typical Range |

| Total Rent | Full monthly rent | currency | 800 – 6000 |
| Utilities | Shared monthly utilities | currency | 50 – 800 |
| Roommates | Total paying occupants | count | 2 – 8 |
| Your Weight | Weight of your room | ratio | 0.7 – 1.8 |
| Other Weight | Average weight of other rooms | ratio | 0.7 – 1.5 |

Practical Examples (Real-World Use Cases)
Example 1: Three-room apartment
Inputs in the {primary_keyword}: total rent 2400, utilities 300, roommates 3, your weight 1.3, others weight 1.0. Weighted rent per unit becomes 2400 ÷ (1.3 + 1.0 + 1.0) = 800. Your rent share is 800 × 1.3 = 1040. Utilities per person are 300 ÷ 3 = 100. The {primary_keyword} returns 1140 total for you.
Example 2: Five roommates with a master suite
Inputs in the {primary_keyword}: total rent 4200, utilities 450, roommates 5, your weight 1.6, others weight 0.95. Total weight is 1.6 + 0.95×4 = 5.4. Rent per weight is 4200 ÷ 5.4 ≈ 777.78. Your rent share is 1244.44. Utilities per roommate are 90. The {primary_keyword} shows 1334.44 due for the master suite roommate, ensuring fairness.
