Financial clarity at every stage. Enter your numbers and get plain English results — estimates, not legal advice, but a real starting point for the conversations that matter.
Tools for couples who want to understand their financial picture before problems arise.
Estimate the numbers most people don't know until they're sitting across from a lawyer.
Tools for life after the divorce is final — understanding your new financial reality as a single household.
Every calculator on Know Your Half uses the same formulas that courts and attorneys reference — translated into plain English inputs so you don't need a law degree to understand your own numbers.
The divorce financial calculator uses the AAML guideline formula for alimony (30% of the higher earner's income minus 20% of the lower earner's income), the Income Shares Model for child support (used by 41 states), and the coverture fraction for retirement accounts (the standard used in QDRO calculations). The home equity and pension calculators use the same math a mediator or attorney would use in the early stages of settlement discussions.
None of these tools produce a legal outcome — they produce a starting point. The goal is to walk into your first attorney meeting with a real sense of the numbers rather than starting from zero. That preparation makes the conversation shorter, more focused, and less expensive.
These calculators work from the inputs you provide. They can't account for factors a judge would weigh: a history of domestic violence, a spouse who voluntarily left the workforce, hidden assets, unusual marital debt, or the specific discretion of your county's family court. In states like Georgia and California, judges have significant latitude to deviate from formulas based on the full facts of a case.
Think of the results as a reasonable ballpark — accurate enough to be useful, not precise enough to be mistaken for legal advice. For that, you need a licensed family law attorney in your state.
