Built for people going through divorce —
not lawyers who already understand it.

Most divorce financial calculators are built by attorneys for attorneys. Know Your Half was built for the person sitting in a parking lot after a hard conversation, trying to understand what their financial life looks like on the other side.

Why we built this

Going through a divorce is one of the most financially complex events in a person's life — and one of the most emotionally overwhelming. Understanding terms like "spousal support," "QDRO," "coverture fraction," and "equitable distribution" shouldn't require a law degree.

Know Your Half was created to bridge that gap. To give anyone — regardless of legal knowledge or financial background — a clear, honest, plain-English picture of what their divorce might look like financially before they walk into a lawyer's office.

Because when you understand your own numbers, you show up to that meeting prepared instead of overwhelmed. And prepared costs less.

What the calculator covers

💰

Alimony / Spousal Support

Estimated monthly amount and duration using the AAML guideline formula. Includes California's unique indefinite support rules for long marriages.

👨‍👧

Child Support

Step-down calculation showing how support changes as each child turns 18. Uses the Income Shares Model used by 41 states.

🏡

Home Equity Split

Your estimated share of home equity based on state property rules — community property or equitable distribution.

🏦

Retirement Account Split

Marital portion calculated using the coverture fraction — the same standard used in QDRO calculations. Includes a plain-English explanation of what a QDRO is and why it matters.

What we use your data for

Nothing personal. All financial inputs you enter are processed entirely within your browser — we never see, store, or transmit your income figures, asset values, or any other personal information. Anonymous usage data (like which questions users reach) is collected via Google Analytics to help us improve the tool.

The formulas behind the estimates

Alimony — AAML (American Academy of Matrimonial Lawyers) guideline formula: 30% of payor's gross income minus 20% of recipient's gross income
Child support — Income Shares Model approximation, the statutory formula in 41 states
Home equity — Market value minus mortgage balance, divided by state property rules
Retirement — Coverture fraction: months married ÷ total months in plan, the standard used in QDRO calculations

Important: Know Your Half provides estimates for educational and informational purposes only. These calculations are not legal advice. Every divorce is different and outcomes vary significantly based on state law, judicial discretion, and individual circumstances. Always work with a licensed family law attorney for advice specific to your situation.
