When to Use a 1:1 Ratio
A 1:1 ratio is the simplest split — two equal shares. Roommates splitting rent in identical rooms, business partners with equal ownership, or couples dividing shared expenses all use 1:1. If both parties contributed equally and benefit equally, this is the right ratio.
Real-World Example
Two co-founders invest $100 into a side project. At 1:1, each contributes $50. Simple, clean, and no arguments — as long as both are putting in the same hours.
Our take: Equal splits work when the underlying contributions are truly equal. If one roommate has the bigger bedroom, or one partner put in more startup capital, a 1:1 split feels fair on paper but breeds resentment fast. Be honest about whether "equal" actually means "equitable" in your situation.
How We Calculated This
Total ratio: 1:1 = 2 parts
Value per unit: 100 / 2 = $50
Part 1: 1 x $50 = $50
Part 2: 1 x $50 = $50
Verification: $50 + $50 = $100
