Please enter the income of both spouses.

Non-binding estimate under the equal-sharing principle with an employment bonus of 1/10 (OLG Frankfurt maintenance guidelines). Separation maintenance (§ 1361 BGB) runs until the divorce is final; post-marital maintenance requires a statutory ground (§§ 1569 ff. BGB) and can be limited in time or reduced (§ 1578b BGB). Not reflected are, among others, housing advantage and capital income, health and pension-provision maintenance, and the specific assessment of need at high incomes. The calculation does not replace legal advice – have it calculated precisely.

Spousal maintenance is not measured by a fixed table but under the equal-sharing principle: what both contributed to the shared standard of living during the marriage is divided. Whoever earns more equalises half the difference.

Basis

How the amount comes about

The starting point is both spouses’ adjusted net incomes. From the payer’s earned income an employment bonus of 1/10 is deducted first (OLG Frankfurt guidelines). The difference in income is halved – that is the maintenance.

Half the difference – the higher earner pays.

The law draws two limits. The minimum subsistence level secures the payer a minimum; below it, the maintenance is smaller. And child maintenance takes priority (§ 1609 BGB): it is deducted from the payer’s income before the spousal maintenance is formed.

Context

Separation, post-marital – and the limits

Until the divorce is final there is separation maintenance (§ 1361 BGB); afterwards only post-marital maintenance, and only with a statutory ground (§§ 1569 ff. BGB), often time-limited (§ 1578b BGB). The calculator reflects the standard case; housing advantage, capital income, health and pension-provision maintenance and the specific assessment of need at high incomes are not included. How the maintenance claims interact is set out on our page on separation & maintenance.

Frequently asked

Frequently asked questions

How does the calculator work out the maintenance?

Under the equal-sharing principle: it forms the difference between both spouses’ adjusted net incomes and splits it – the higher earner pays half. From the payer’s earned income an employment bonus of 1/10 is deducted first (OLG Frankfurt guidelines). The payer’s minimum subsistence level caps the amount.

What is the difference between separation and post-marital maintenance?

Separation maintenance runs from separation until the divorce is final (§ 1361 BGB) and is granted generously. Post-marital maintenance only applies with a statutory ground (§§ 1569 ff. BGB, e.g. childcare, age, illness) and can be limited in time or reduced (§ 1578b BGB). The calculation is the same in both cases.

What is the employment bonus?

Whoever works may keep part of their earned income first, before the maintenance is formed – under the OLG Frankfurt guidelines, 1/10. It creates an incentive to work and benefits the employed payer.

Is child maintenance taken into account?

Optionally. If you enter the child maintenance (amount paid), the calculator deducts it from the payer’s income first, before forming the spousal maintenance – minor children take priority (§ 1609 BGB).

Is the result legally binding?

No, it is a first orientation. Not reflected are, among others, housing advantage and capital income, health and pension-provision maintenance, and the specific assessment of need at high incomes. For a reliable calculation you should have the figures reviewed by a lawyer.
