Property Division Calculator

Calculate equitable division of marital property and separate assets in divorce.

About this calculator

Divorce property division starts by separating what belongs to the marriage from what belongs to each spouse individually, since in most states only marital property — assets and debts accumulated during the marriage — actually gets divided, while separate property brought into the marriage or received individually by gift or inheritance typically stays with its original owner. This calculator first nets marital debts against marital assets to find the net marital estate actually available to split, then applies whatever percentage split you set to divide that net estate between the two spouses. Each spouse's final total then adds their own separate property back on top of their marital share, since that property was never part of the pool being divided in the first place.

The equalization payment shown represents the cash amount that would need to change hands if the marital assets themselves can't be split cleanly down the percentage line — common when the marital estate consists largely of illiquid property like a house or retirement account that can't simply be cut into two proportional pieces. What this calculator can't determine for you is what split percentage is fair or legally required in your situation: community property states generally start from an even 50/50 presumption for marital property, while equitable distribution states weigh a range of factors — length of marriage, each spouse's financial and non-financial contributions, and future earning capacity among them — that can justify a meaningfully uneven split.

How to Use This Calculator
  1. Enter Total Marital Assets and Total Marital Debts (community or marital property).
  2. Set Spouse 1 and Spouse 2 Separate Property — pre-marital assets or inheritances.
  3. Enter Spouse 1 Contribution % and the agreed or proposed Equitable Split %.
  4. Review Spouse 1 Total and Spouse 2 Total including separate property.
  5. Separate property is generally not divided in divorce but must be clearly documented.
  6. Consult an attorney for jurisdiction-specific rules on commingled property and debt allocation.

Frequently Asked Questions

Why does separate property get added back on top after the marital estate is already split?

Separate property, like assets owned before the marriage or received individually through inheritance, generally isn't part of the pool subject to division at all in most states, so it stays entirely with whichever spouse already holds it rather than being blended into the percentage split. Adding it back after dividing only the net marital estate reflects that these two categories of property are legally treated completely separately.

What does the equalization payment actually represent in a real divorce?

It's the dollar amount that would need to be paid from one spouse to the other to make an unequal division of specific assets add up to the intended overall percentage split, which comes up constantly in practice because a house, a retirement account, or a business usually can't be physically divided down an exact percentage line. Rather than forcing a sale, one spouse often keeps a particular asset and pays the other spouse cash to balance out the value.

How do I know what split percentage to use for my state?

Community property states, including California and Texas among others, generally start from a 50/50 presumption for marital property, while most other states follow an equitable distribution model where a judge or the parties weigh factors like marriage length, income, and contributions to arrive at a split that's fair but not necessarily even. Since this varies significantly by state and by the specific facts of the case, treat the split percentage as an input you supply based on your own state's rules or your attorney's guidance, not something this calculator determines.

Do marital debts always reduce what gets divided between spouses?

In this calculator's model, yes — marital debts are subtracted from marital assets before any split is applied, reflecting that in most jurisdictions marital debt is treated as a shared obligation the same way marital property is treated as a shared asset. In practice, some debts can be allocated differently based on who incurred them or what they were used for, which a full property settlement negotiation or court order would address in more detail than a single subtraction can.
