Pick your state

Child support, alimony, and property division are governed by state law — the same facts can produce very different outcomes in different states. Choose your state for its specific rules:

Why state-specific matters

Most national calculators apply one generic formula to every state. In reality, about 41 states use the income shares model (both parents' incomes combined, obligation prorated), a handful use percentage of income (a flat percentage of the paying parent's income), and three use the Melson formula. Alimony varies even more — some states have exact statutory formulas, most leave it to judicial discretion. Property division splits 50/50 in the nine community-property states and "equitably" in the rest. Our calculators apply your state's actual model and cite the governing statute on every page.

How our estimates work

Every calculator page explains its formula, cites the state statute or court rule it's based on, and links to your state's official calculator where one exists. Results are educational estimates — courts can and do deviate from guidelines. Read our full methodology.
