When living with friends, roommates, family or partners, one of the first things you have to make is a distribution plan for costs. Expense sharing can be a simple process, but the choice of how to do it can be significant both with regard to fairness and transparency.
The two most popular methods are expense splitting (equal cost) and percentage-based splitting. There are benefits to each method and in some situations one might be more appropriate than the other.
What is Equal Expense Splitting?
The easiest and most popular option is the equal expense splitting method. The overall expense is shared by everyone equally, whether or not they have a high or low income, or use and contribute to the group.
If 4 friends go out for dinner and each pays $200 for the dinner, then each person pays:
$200 ÷ 4 = $50
This is a method that can be used due to its simplicity of calculation and understanding. All people contribute the same amount of which is ideal when everyone is getting similar value from the expense.
Advantages of Equal Splitting
Quick and easy calculations
Easy to understand and monitor
Can be used for group excursions and activities

Potential Drawbacks
May not feel it's always fair
Doesn't account for differences in income
Does not recognise that there are levels of use or participation.
For instance, if one roommate consumes way more utilities than the other, then an equal breaking down of the utilities may be incorrect.
Understanding the concept of percentage expense splitting.
The splitting of expenses on a Percentage basis, expenses are split based on the pre-determined percentages. These percentages could be based on income, use, or ownership, or other agreed on factor.
If a monthly expense costs $1000, and two people agree to contribute according to their income:
Person A pays 60% = $600
Person B pays 40% = $400
It is a technique frequently employed by couples, families and households with vastly different financial situations.
