The poster, a 56-year-old man, lives in the house where his two adult daughters (aged 22 and 23) grew up. Both daughters are employed full-time and have moved in with their long-term boyfriends (aged 23 and 24, respectively), resulting in six adults living in the home.
While the daughters and their partners cover their personal expenses, such as cars, insurance, gas, and groceries, the poster noted that the household utility bills have increased due to the extra occupants. He sent a text message stating that moving forward, he would divide the utility bills by three (one share for himself and one share for each couple) and each party would pay their portion, using a recent $300 electric bill as an example where each of the three units would owe $100. This decision immediately caused conflict, with the daughters claiming the division was unfair, leading the poster to question if he was in the wrong for implementing this cost-sharing arrangement.

According to Dr. Morgan Ross, a specialist in domestic economics and shared living arrangements, “When household dynamics shift from a nuclear family structure to a multi-unit living situation, established financial precedents often fail, requiring explicit, needs-based renegotiation of shared costs.”
The poster’s approach of dividing the total utility bill by three units (one for the father, one for couple A, one for couple B) establishes equality between the parties, which is simple to implement. However, this method fails to account for the actual consumption load; one single person paying the same amount as a couple places a disproportionately higher burden on the single occupant. The daughters’ reaction suggests they perceive this as unfair, likely feeling that the cost should reflect the number of users, or at least acknowledge that two couples generate more utility usage than one single adult.
A more equitable path forward, which often promotes better long-term harmony in shared living situations, would involve calculating the cost based on the number of individuals or proposing a base rate for the father and an additional charge per partner occupying the space. The father’s action was rooted in a necessity to address rising costs, but the metric chosen (dividing by three units) created an internal equity issue. A shift toward a per-person or per-couple consumption model should be discussed to fairly address the increased utility load.

The poster is seeking to fairly distribute the increased cost of shared household utilities now that six adults reside in the home, while his adult daughters feel the proposed division method is inequitable. The core conflict centers on defining financial responsibility for shared resources when adult children move back in with partners versus the father’s desire to cover increased usage fairly.
Should the poster continue with the proposed division of total household utilities by three parties, or is a different cost-sharing model, perhaps based on the number of people per sub-unit (i.e., 1 person vs. 2 people), more appropriate and less likely to cause resentment?
