Estimate your alimony
Based on Florida's durational alimony guidelines.
Results are estimates only, not legal advice.
This calculator provides estimates based on Florida's durational alimony guidelines using a simplified formula. Actual alimony awards depend on many factors including but not limited to: standard of living during the marriage, financial resources of each party, earning capacity, contributions to the marriage, and the court's discretion. This tool does not constitute legal advice. Consult with a qualified Florida family law attorney for guidance specific to your situation.
Durational Alimony Categories Based on The Marriage Length
Florida divides marriages into three categories, measured from your wedding date to the date the divorce was filed:
The longer the marriage, the longer the potential alimony term. But Florida law sets strict durational caps:
- Short-term marriages: Alimony can last no longer than 50% of the marriage length
- Moderate-term marriages: No longer than 60% of the marriage length
- Long-term marriages: No longer than 75% of the marriage length
Example: A 12-year marriage is moderate-term. The maximum durational alimony term would be roughly 7 years and 2 months — and that is generally the ceiling.
Courts can exceed these limits only in truly exceptional circumstances, and even then, the bar is very high. We expect to see more case laws develop over time to give better guidance.
