A whole month,
split pro rata.
The simulator splits a single bill. Here's what it looks like across an entire household budget: rent, groceries, energy, insurance, subscriptions.
A fixed example, for illustration — the amounts can't be edited here.
The household
Two incomes, one shared life. Each person accounts for a different share of the household income — and that share is what the split is based on.
Household income €3,500
This month's shared expenses
The most common items in a household budget. Each expense is split individually according to income, exactly as the app does it.
| Item | Amount | Alice 60% | Tom 40% |
|---|---|---|---|
| Rent | €950 | €570 | €380 |
| Groceries | €480 | €288 | €192 |
| Electricity & gas | €130 | €78 | €52 |
| Water | €30 | €18 | €12 |
| Internet & mobile | €65 | €39 | €26 |
| Insurance | €85 | €51 | €34 |
| Transport | €120 | €72 | €48 |
| Subscriptions | €35 | €21 | €14 |
| Total | €1,895 | €1,137 | €758 |
What it changes, concretely
Same budget, two ways to share it. The gap only really stands out once you work out what each person has left to live on.
Equal shares
Pro rata
Pro rata, Alice and Tom each keep 45.9% of their income for themselves. With equal shares, Alice keeps 54.9% and Tom only 32.3%.
On this budget, Tom pays €189.50 less every month than with equal shares — that's €2,274 over a year.
It isn't a universal rule
Pro rata isn't “the” right answer: it's a starting point for the conversation. Some households prefer equal shares, others a mix of the two. Prorata shows you both numbers — the decision stays yours.
