legal.alimony-duration Calculator
Estimates alimony duration and total payment based on marriage length, income disparity, and standard judicial guidelines for the relevant jurisdiction. Long-term marriages (over 10 years) often result in indefinite support; shorter marriages typically use a half-length-of-marriage rule.
Inputs
Marriage Years
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Income Disparity
Reference formula or conversion factor shown for context.
Marital Standard Income
Reference formula or conversion factor shown for context.
Results
estimated alimony duration (yrs)
Weighted average time to receive the bond's cash flows (years). Also a price sensitivity measure: duration of 7 means a 1% rise in yields drops the bond price ~7%.
monthly need
Sample size or count used in the calculation.
income gap
Sample size or count used in the calculation.
need relative to lifestyle
The value at the specified point or condition.
rule of thumb
A widely used practical approximation or heuristic for this field — useful for quick estimates but not a substitute for rigorous calculation.
