Alimony Calculator
Calculate alimony increase or estimate monthly alimony from income and expenses.
In estimate mode, the tool does not use a fixed official rate; it produces a transparent range from income, essential expenses and need gap.
How is alimony calculated?
In estimate mode, the tool evaluates the paying party's capacity remaining after essential expenses together with the recipient side's need gap. For child support, child expenses are distributed according to the parties' paying capacity; for spousal support, the recipient's income-expense gap is compared with the paying party's capacity. In increase mode, the current monthly alimony is increased by the selected annual percentage.
Scope and assumptions
The tool does not provide legal advice or a case result. For child support, it uses an estimate based on the combined effect of education, health and care costs; for spousal support, it uses the gap between basic living expenses and net income. If the judgment text refers to CPI, PPI or a fixed rate, that rate should be entered manually in increase mode.
