New York's spousal maintenance laws underwent major reforms in 2016, creating standardized formulas for calculating both temporary and permanent support. The state uses an income-shares model that considers both parties' earnings and the length of the marriage. Temporary maintenance applies during divorce proceedings, while post-divorce maintenance continues after the divorce is finalized.

Courts must follow the statutory formula unless they document why a deviation is warranted. The formula aims to help the lower-earning spouse maintain a similar standard of living while becoming self-supporting. New York distinguishes between marriages with and without children, applying different calculations for each scenario.

The payor's income is capped at $203,000 for calculation purposes, though courts can award additional support for income above this threshold. Understanding these guidelines helps both parties set realistic expectations and negotiate fair agreements.

Your spousal support calculation provides a baseline estimate using New York's statutory formula. The results show both temporary maintenance (during divorce) and post-divorce maintenance amounts. The duration range reflects judicial discretion - courts typically award support for 15-50% of the marriage length, depending on various factors.

The monthly amount represents the guideline calculation, but judges can deviate based on factors like age, health, earning capacity, and marital standard of living. If there's a significant income disparity or one spouse sacrificed career advancement for the family, support may be adjusted upward.

Remember that spousal support is modifiable if circumstances substantially change, unlike property division which is final. The calculation assumes both parties are W-2 employees; self-employment income requires additional considerations.
