Choose how to split rent
This rent split calculator lets you compare three ways of splitting your rent: 50/50, based on income, or adjusted for living space.
50/50
Both people pay half of the rent. This is the simplest option and can work well when incomes and living arrangements are similar.
By income
Each person pays a share of the rent based on their share of the couple's combined income. This can be useful when incomes differ.
By living space
Adjust the split when one person has significantly more private living space.
50/50 or Income-Based Rent Splitting?
Couples commonly choose between splitting rent equally and splitting it proportionally based on income. A 50/50 split is simple and gives both people the same rent amount. An income-based split changes each person's contribution according to their share of the couple's combined income.
Neither method is universally fair. The right choice depends on your incomes, living arrangements and what you both agree feels fair. Learn more about 50/50 vs proportional rent splitting.

Example Calculation
Here's an example of how the rent split calculator works. Let's say your monthly rent is €1,200, and you earn €2,400 while your partner earns €1,600. Your combined income is €4,000, so you earn 60% of the total and your partner earns 40%.
| Split Method | You | Your Partner | Total Rent |
|---|---|---|---|
| Based on income |
€720 60% |
€480 40% |
€1,200 |
| 50/50 |
€600 50% |
€600 50% |
€1,200 |
With an income-based split, you pay €120 more and your partner pays €120 less than with a 50/50 split.
