How Is Spousal Support Calculated in California?
Spousal support—commonly referred to as alimony—is one of the most misunderstood aspects of California divorce law. Whether you expect to receive support or may be required to pay it, understanding how California courts calculate these payments is essential for protecting your financial future.
At M.C. Law, P.C. our Los Angeles family law attorneys guide clients through every step of the spousal support process, from the initial temporary order to final determination and post-judgment modifications. Here’s what you need to know about how spousal support is calculated in California.
Two Types of Spousal Support in California
California divides spousal support into two major categories, each with its own purpose and calculation method:
1. Temporary Spousal Support
Temporary support is awarded early in the divorce process to help the lower-earning spouse manage living expenses until the case is finalized. Courts typically calculate temporary support using a mathematical formula through a program known as Dissomaster.
This formula considers:
- Each spouse’s gross monthly income
- Tax filing status
- Health insurance deductions
- Union dues or mandatory retirement contributions
- Certain childcare or support obligations
The goal is to stabilize the financial situation while divorce proceedings are ongoing.
2. Permanent (Long-Term) Spousal Support
Despite the name, “permanent” support is not necessarily permanent. Instead, it refers to the support ordered at the end of the divorce. These payments may last for a set duration—and can be modified or terminated if circumstances change.
Permanent support is not calculated with the Dissomaster program. Instead, California judges rely on a detailed list of factors outlined in Family Code §4320, including:
- The length of the marriage
- Each spouse’s earning capacity
- Whether one spouse stopped working to raise children or support the household
- The ability of the higher-earning spouse to pay
- The marital standard of living
- Age and health of both spouses
- Documented history of domestic violence
- Any other factors the court finds equitable
This approach allows judges to tailor support orders to each couple’s unique situation.
How the Length of the Marriage Affects Support
California distinguishes between short-term marriages (under 10 years) and long-term marriages (10 years or more):
- In short-term marriages, support often lasts roughly half the length of the marriage.
- In long-term marriages, courts generally do not set a specific end date, allowing support to continue until one spouse becomes financially self-supporting or circumstances change.
The goal is fairness—not punishment or reward—based on the couple’s financial interdependence during the marriage.
When Spousal Support Can Be Modified
Support orders can be changed if either spouse experiences a significant shift in circumstances, such as:
- Job loss or income increase
- Retirement
- Remarriage or cohabitation affecting financial need
- Disability or major health change
- Change in childcare responsibilities
Our attorneys help clients petition for modifications or defend against unfair reduction requests.
