When to Use a 3:5 Ratio
A 3:5 ratio — roughly 37.5/62.5 — shows up in partnership splits where one person contributes more capital or time. It's also used for splitting shared expenses between a couple where one earns about 60% more than the other.
Real-World Example
A couple splits $400 in monthly shared expenses. One earns $55K and the other earns $90K, roughly a 3:5 income ratio. The lower earner pays $150 and the higher earner pays $250. Both contribute about 22% of their take-home pay.
Our take: Income-based expense splitting often rounds to 3:5. If you earn $60K and your partner earns $100K, a 3:5 split of shared costs means each person pays the same percentage of their income. That's mathematically fair even though the dollar amounts are unequal.
How We Calculated This
Total ratio: 3:5 = 8 parts
Value per unit: 400 / 8 = $50
Part 1: 3 x $50 = $150
Part 2: 5 x $50 = $250
Verification: $150 + $250 = $400
