Tips for managing different income levels in relationships without creating power imbalances
By Dan Kauna, August 30, 2026Money discussions in relationships often get tricky when one partner earns Ksh50,000 a month while the other earns Ksh150,000.
Splitting expenses straight down the middle might seem fair on paper, but it usually leaves the lower earner struggling to keep up with rent, groceries, and basic savings.
Over time, this setup creates unspoken resentment, where one person feels financially drained while the other enjoys ample disposable income.
Handling unequal incomes requires moving away from identical contributions toward proportional expense-sharing. In this model, both partners contribute a percentage of their earnings toward household costs rather than a fixed cash amount.
If one partner earns 70 percent of the combined income, they cover 70 percent of shared bills, while the other covers 30 percent. This ensures both individuals experience an equal financial weight relative to their paycheck, preserving financial dignity and independence.
Embrace proportional contribution
When couples divide bills proportionally, both partners retain discretionary income for personal goals, extended family support, or individual savings.
Splitting expenses 50/50 when salaries differ wildly forces the lower earner to live at the edge of their financial limits or rely on the higher earner for subsidies.
That dynamic easily introduces an unhealthy power imbalance where the higher earner feels entitled to make major decisions unilaterally.
Research supports financial consideration as a stabilising factor in relationships.
In a study published in the Journal of Consumer Research in December 2023, researchers found that merging finances and working from a unified budget “improves how partners feel about how they handle money, promotes financial goal alignment, and sustains communal norm adherence”.
By agreeing on proportional contributions, partners shift from a transactional view of money to a collaborative system that values each person’s role in the home.
Building a workable structure
A working approach for many households is the joint-and-separate account model.
Both individuals maintain personal bank accounts while opening a shared account dedicated exclusively to joint obligations like utilities, rent, and household food. Every month, each partner transfers their agreed percentage into the joint account.
Whatever remains in their personal accounts belongs entirely to them, without requiring approval or explanation from the other. This hybrid structure eliminates friction around daily personal choices, whether buying personal items or supporting extended family.
Open conversations about money, held regularly without judgement, keep couples’ financial planning transparent even as incomes fluctuate over time.
