How Alimony Works in Washington D.C.
Washington D.C. is a judicial discretion — moderate reliability — court has wide discretion. Courts in Washington D.C. may award permanent (open-ended) support in appropriate cases.
How the amount is determined: Need-based — broad judicial discretion.
How long it lasts: No statutory limit.
Use the calculator above with your actual incomes and marriage length to get a low / estimated / high range, the expected duration, and the total lifetime cost.
How the Calculator Works
This free calculator estimates alimony the same way attorneys do. In formula states — Illinois, Colorado, New York, Kansas, Wisconsin, New Hampshire, and Massachusetts — it applies the exact statutory math. In discretion states, where judges weigh many factors, it uses the American Academy of Matrimonial Lawyers (AAML) guideline: 30% of the payer's gross income minus 20% of the recipient's gross income, capped at 40% of combined income.
You get a low / estimated / high range because every state's courts have latitude. Duration follows AAML guidelines (typically 40–50% of the marriage length) or the state's own statutory rules where they exist. The lifetime total — monthly payment × duration — is usually the number that changes negotiations.
Formula States vs. Discretion States
Formula states (IL, CO, NY, KS, WI, NH, MA) have statutory math that produces highly reliable estimates. For example, Illinois computes 33.33% of the payer's net income minus 25% of the recipient's net income, capped at 40% of combined net income.
Hybrid states (CA, FL, PA) use a formula as a starting point (like California's temporary-support guideline of 40% of payer net minus 50% of receiver net) but leave the final award to judicial discretion.
Discretion states give judges wide latitude. Our estimates use the AAML guideline as the negotiation baseline attorneys themselves use, adjusted for the factors you toggle — career sacrifice, health issues, standard of living, retraining needs, and minor children.
Assumptions and Limitations
Results are educational estimates, not legal advice or a guarantee of what a judge will order. Actual awards depend on assets, debts, earning capacity, tax treatment, health, child custody arrangements, and the specific facts of your case. Formula states compute against net income in some cases — this calculator uses gross income with a standard 80% net proxy where the law calls for net income, which is a simplification.
Consult a licensed family law attorney in your state for advice specific to your situation.
