Key Factors That Influence Spousal Support

State laws consider many variables when determining alimony. This calculator focuses on the most significant factors to provide a reliable estimate.

⏳

Duration of the Marriage

Courts often categorize marriages as short, mid, or long-term. Longer marriages typically correlate with longer, and sometimes higher, alimony awards.

⚖️

Income Disparity

The core of any alimony calculation is the difference between one spouse's financial need and the other spouse's ability to provide support.

🏡

Standard of Living

Courts aim to help the lower-earning spouse maintain a lifestyle reasonably comparable to the one established during the marriage, where possible.

📜

State-Specific Laws

Alimony laws vary significantly by state. This tool uses common formulas, but the final amount will be determined by your state's specific guidelines.

Spousal Support & Alimony: Common Questions

Gross income is your total earnings before taxes and deductions. Net income is your take-home pay after taxes. While this calculator uses gross income as a starting point (as many states do), it also performs a simplified tax calculation to better estimate each spouse's net disposable income, which is crucial for determining alimony.

The duration of the marriage is one of the most significant factors. In many states, the length of alimony payments is often a percentage of the length of the marriage (e.g., 30-50%). Very long-term marriages (e.g., 20+ years) may sometimes result in permanent or indefinite alimony.
