About the Divorce Asset Division Calculator
This divorce asset division calculator totals the marital estate — assets minus debts — and works out how much each spouse walks away with once you decide who keeps what. List each item with its value and whether spouse A keeps it, spouse B keeps it, or it is sold and shared, and the calculator shows each side’s total and the one-off equalization payment needed to reach the split you are aiming for.
It is useful for couples negotiating a settlement, people preparing for mediation, and anyone checking a proposed property division. Community property states such as California generally split marital property 50/50 (Texas and a few others allow a “just and right” division that can be unequal), while equitable distribution states divide what is fair, which may be 60/40 or another ratio — change the percentage to test offers.
Enter net values: equity rather than home price, and debts as negative numbers. Values are treated at face value, so a dollar in a pre-tax 401(k) counts the same as a dollar of cash; see the FAQ on adjusting for taxes. Separate property (owned before marriage or inherited) should normally be left off the list.
With the default inputs, the equalization payment is $117,000.00. Change any value above to recalculate instantly.
How to use the divorce asset division calculator
- 1List every marital asset and debt on its own line with its current net value.
- 2Enter debts as negative numbers (e.g. -9000).
- 3Mark each line A or B for who keeps it, or J if it will be sold or shared.
- 4Set spouse A’s target share — 50% in community property states.
- 5Read the equalization payment and the item-by-item table.
Formula and method
The marital estate is every listed asset minus every listed debt. Each item is assigned to spouse A, spouse B, or shared; shared items (for example a house that will be sold) are divided by the chosen percentage p. The target for spouse A is p times the net estate, and spouse B’s target is the remainder.
The equalization payment is the difference between spouse A’s target and what A actually receives from the items assigned. If A keeps more than the target, A pays B the difference; if less, B pays A. Because debts are negative values, taking on a debt reduces what that spouse is treated as receiving.

Worked examples
A keeps the house and 401(k), 50/50 split
Assets total $405,000 and debts $15,000, so the estate is $390,000 and each spouse’s half is $195,000. A keeps items worth a net $312,000 and B keeps $78,000, so A owes B an equalization payment of $117,000.
Same items with a 60/40 split in A’s favor
At 60/40, spouse A’s target is $234,000 and B’s is $156,000. A still holds $312,000 of net assets, so the payment to B falls to $78,000.
House sold and proceeds shared
The house and mortgage net to $100,000, split $50,000 each. Adding A’s $60,000 pension and B’s $40,000 savings gives A $110,000 and B $90,000, so A pays B $10,000 to reach an even $100,000 each.
Frequently asked questions
How are assets divided in a divorce?+
Nine US states use community property rules; California, Louisiana and New Mexico require an equal split, while others such as Texas start from community ownership but may divide it unequally when that is “just and right”. The rest use equitable distribution, where a judge divides property fairly based on factors like the length of marriage, each spouse’s income and contributions, and custody arrangements — not necessarily equally.
What is an equalization payment?+
It is a one-time payment from the spouse who keeps more than their share of the marital estate to the other spouse, so that the overall division matches the agreed percentage without selling assets such as the family home.
Should retirement accounts be valued the same as cash?+
Not always. A pre-tax 401(k) or traditional IRA will be taxed when withdrawn, so $100,000 in one may be worth closer to $75,000–$80,000 after tax. Many couples discount pre-tax accounts or split them directly with a QDRO instead.
Is property owned before marriage split in a divorce?+
Generally no. Separate property — assets owned before marriage, gifts and inheritances kept separate — usually stays with the original owner, though growth in value or mixing with marital funds can make part of it marital.
How are debts divided in a divorce?+
Marital debts are divided along with assets, and the spouse who takes a debt is credited for it in the split. Creditors are not bound by the divorce decree, so joint accounts should be refinanced or closed to protect both spouses.
