1 The Myth of Equality
If Ana earns 4,000 USD and Carlos earns 2,000 USD, and they split 1,800 USD in expenses 50/50, each pays 900 USD. For Carlos, that's 45% of his income. For Ana, only 22.5%.
Carlos ends up with less money for savings, emergencies, or personal enjoyment. Over time, this creates frustration and imbalance in the relationship.
2 The Alternative: Proportional Split
With proportional splitting, each person contributes according to their capacity. Ana represents 67% of total income, Carlos 33%. From the 1,800 USD: Ana pays 1,200 USD and Carlos pays 600 USD.
Both contribute the same relative effort (30% of their income each). It's equity, not equality. And equity strengthens relationships.
3 Benefits of Proportional Split
- Both maintain the same savings percentage
- Eliminates resentment over income differences
- Automatically adapts to salary changes
- Reflects a true financial partnership
Proportional splitting recognizes that couples are a team. Each contributes what they can, and both build toward their goals together.
