Estimate a rough monthly alimony from an income difference.
A common rough approach treats roughly a third of the income difference as annual support, capped by the recipient's needs. The result is a starting estimate, not a court order. Alimony rules differ sharply between states and depend on marriage length and lifestyle, so any estimate should be confirmed with legal advice.
