Spousal support (alimony) is less formulaic than child support. Some states use guidelines; many leave more to the judge. Either way, a consistent set of factors drives the number.
The main factors
Courts typically weigh the length of the marriage, each spouse's income and earning capacity, the standard of living during the marriage, each person's age and health, and whether one spouse gave up career progress to support the family or raise children. The bigger the income gap and the longer the marriage, the more likely and larger the support.
Formula vs. discretion
Some states apply a guideline formula (often based on the difference in incomes) to set a starting figure, especially for temporary support. Others give judges broad discretion to weigh the factors and decide. That's why similar couples can see different outcomes in different states.
Duration matters too
Support isn't just an amount, it's also a length of time. Short marriages often mean short or no support; long marriages can mean longer terms. Many awards are 'rehabilitative,' meant to last only until the receiving spouse can become self-supporting.
If your divorce is amicable, you can negotiate the amount and duration yourselves, including agreeing to none, and write it into your settlement, avoiding a contested fight over it.
