Should couples split expenses 50/50?
A 50/50 split is simple but may not be fair if incomes differ significantly. An income-based split allocates shared costs proportionally to each person's income.
What is an income-based split?
Each person contributes to shared costs proportionally. If one earns 60% of combined income, they pay 60% of shared expenses.
Should personal spending be included?
Yes. Personal spending covers each person's individual costs that are not shared, such as personal clothing, hobbies or subscriptions.
How should savings be handled?
Enter the total household savings target. The result shows whether the combined income supports the savings goal after all expenses.
Can this calculator help roommates?
Yes. Enter each person's income and shared costs. The income-based split shows a fair contribution for any two people sharing costs.
