Understanding Alimony

Alimony (also called spousal support or maintenance) is a legal obligation to provide financial support to a spouse after separation or divorce. Courts consider many factors when determining alimony, including income disparity, marriage duration, standard of living, and each spouse's earning capacity.

Common Types of Alimony
  • Temporary: Support during the divorce process
  • Rehabilitative: Support until the recipient becomes self-sufficient
  • Permanent: Long-term or indefinite support (typically for long marriages)
  • Reimbursement: Repayment for financial support provided during marriage (e.g., education)
  • Lump-sum: One-time payment instead of ongoing payments
Key Factors Affecting Alimony
  • Income disparity between spouses
  • Length of the marriage
  • Age and health of both parties
  • Standard of living established during marriage
  • Contributions to career or education of the other spouse
  • Child custody arrangements and child support obligations
  • Tax consequences
  • State-specific laws and guidelines

Note: Laws regarding alimony vary widely by state and country. The information provided is general in nature. Family courts have significant discretion in determining alimony amounts and duration. This calculator is for educational purposes only.

Example Formula - California Guideline:
Estimated Monthly Alimony = (0.40 × Higher Income) − (0.50 × Lower Income) ÷ 12
