How to use the Alimony Calculator

To use this calculator, input the monthly income of the paying spouse, the monthly income of the receiving spouse, and the total length of the marriage in years. After entering these details, click on the “Calculate” button to get an estimate of the alimony.

How the Alimony is Calculated

This calculator takes the following steps to estimate alimony:

  1. Calculates the difference between the monthly income of the paying spouse and the receiving spouse.
  2. Determines a duration factor based on the length of the marriage, simplified as length of marriage divided by 10.
  3. Multiplies the income difference by 30% and then by the duration factor to estimate the alimony.


This alimony calculator provides an estimate based on simplified assumptions. It does not account for all factors that a court may consider in determining alimony, such as financial needs, expenses, health, lifestyle, contributions to the marriage, and other unique circumstances. For a more accurate determination, it is advisable to consult a legal professional.
