Marital Asset Division Calculator

Estimate how marital assets and debts may be divided between spouses based on each party's financial contributions and applicable division method.

Division Method

Spouse A Contribution % (0–100)

Spouse B Contribution % (auto-calculated)

Marital Assets

Primary Home Value ($)

Home Mortgage Balance ($)

Investment / Brokerage Accounts ($)

Retirement Accounts (marital portion, $)

Vehicles Total Value ($)

Vehicle Loan Balances ($)

Savings / Checking Accounts ($)

Other Marital Assets ($)

Other Marital Debts / Liabilities ($)

Separate (Non-Marital) Property

Spouse A Separate Property ($) excluded from division

Net Marital Estate

Net Marital Estate = Gross Marital Assets − Total Marital Debts

Where:

Gross Marital Assets = Home Value + Investments + Retirement + Vehicles + Savings + Other Assets
Total Marital Debts = Mortgage + Vehicle Loans + Other Debts
Home Equity = Home Value − Mortgage Balance

Equitable Distribution

Spouse A Share = Net Marital Estate × (Contribution A% ÷ 100)

Spouse B Share = Net Marital Estate × (1 − Contribution A% ÷ 100)

Community Property (Equal Split)

Each Spouse Share = Net Marital Estate × 0.50

Total Post-Division Net Worth

Spouse Total = Marital Share + Separate Property

Equitable distribution does not mean equal — courts in 41 U.S. states divide assets based on fairness, considering each spouse's financial and non-financial contributions.
Community property states (AZ, CA, ID, LA, NV, NM, TX, WA, WI) generally split marital assets 50/50.
Separate property (pre-marital assets, inheritances, gifts) is typically excluded from division but may be subject to commingling rules.
Retirement accounts acquired during marriage are generally marital property; a QDRO (Qualified Domestic Relations Order) is required to divide 401(k)/pension plans.
Contribution percentages can reflect income earned, homemaking, childcare, and other non-monetary contributions as recognized by courts.
This tool does not account for tax implications of asset transfers (e.g., capital gains on investment accounts, early retirement withdrawal penalties).
