An alimony (spousal support) calculator estimates the monthly payment one spouse may owe the other after divorce. The amount depends on income disparity, marriage length, and state-specific formulas or judicial guidelines.

Fórmula

Alimony = (Higher Earner Income × Percentage) – (Lower Earner Income × Percentage)
I_h
Higher Earner Income ($/month) — Gross or net income of the spouse earning more
I_l
Lower Earner Income ($/month) — Gross or net income of the lower-earning spouse
D
Marriage Duration (years) — Length of the marriage, used to determine duration of payments

Guia passo a passo

  1. 1Determine each spouse’s gross monthly income
  2. 2Apply the state’s formula or guideline percentage (e.g., 30–35% of the difference)
  3. 3Adjust for marriage duration to determine the length of payments
  4. 4Factor in tax implications and any existing child support obligations

Perguntas frequentes

Is alimony the same as child support?

No. Alimony supports the lower-earning spouse; child support is specifically for the children’s expenses. They are calculated separately and serve different purposes.

Can alimony be modified after the divorce?

Yes, in most states either party can request a modification based on a material change in circumstances, such as job loss, retirement, or the recipient’s increased income.
