A divorce cost calculator gives a planning range for what one spouse might spend on a divorce, based on how the case is handled. Formula: Low/high = caseCosts[type] + filing fee; if children: ×1.15 / ×1.25; if complex assets: ×1.2 / ×1.4. Mid = (low+high)/2. An uncontested divorce with attorney review and a $300 filing fee comes out at $1,800 to $5,300, with a midpoint of $3,550; a contested case with children and complex assets can run many times that.

How to use the divorce cost calculator
- Choose the case type: DIY forms, uncontested, mediated or contested.
- Enter your local court filing fee.
- Say whether minor children or complex assets are involved.
- Read the low, high and midpoint estimate per spouse.
What is the divorce cost formula?
- Low and high = the tool’s range for your case type + your court filing fee
- Minor children: low × 1.15 and high × 1.25
- Complex assets (a business, pensions, several properties): low × 1.2 and high × 1.4
- Estimate = midpoint of the low and high figures, per spouse
Divorce cost calculator worked example
With a $300 filing fee:
| Case | Low | High | Midpoint |
|---|---|---|---|
| DIY forms, no children | $500 | $1,100 | $800 |
| Uncontested with attorney review | $1,800 | $5,300 | $3,550 |
| Uncontested, with children | $2,070 | $6,625 | $4,348 |
| Mediated | $3,300 | $10,300 | $6,800 |
| Contested, children and complex assets | $21,114 | $88,025 | $54,570 |
The base ranges and multipliers are planning assumptions built into the divorce cost calculator, not survey data. Your county, your lawyer’s rates and how much you and your spouse disagree will move the real figure far more than any formula.
What you actually pay for
- Court fees: set by each state or county. In California, for example, the first filing generally costs $435 to $450.
- Lawyer time: usually billed by the hour plus a retainer; conflict over custody, support or property multiplies the hours.
- Mediation: a neutral mediator helps both spouses reach an agreement, and the fee is often shared.
- Experts: appraisers, business valuators, custody evaluators and pension specialists add cost in complex cases.
- Service and copies: serving papers and certified copies have their own small fees.
Ways to lower the cost
- Agree on as much as possible before filing; an uncontested case needs far fewer hearings.
- Use your court’s self-help center and official forms if your case is simple.
- Ask about a fee waiver if you cannot afford court fees; California uses Form FW-001 for this.
- Consider mediation or limited-scope representation, where a lawyer handles only part of the case.
- Organize financial documents yourself so paid time is not spent gathering them.
Costs that come after the decree
Dividing a retirement plan can need a qualified domestic relations order (QDRO), refinancing the home has closing costs, and running two households changes your budget. Include these in your plan alongside the legal bill shown by the divorce cost calculator.
Taxes matter too. Under current federal rules, alimony paid under a divorce or separation agreement made after 2018 is not deductible by the payer and is not taxable income to the recipient, and child support is neither deductible nor taxable. Your filing status for the year depends on whether you are married on December 31.
Estimates for education only, not legal, tax or financial advice. Rules vary by state and change over time; check with the official agency or a licensed professional.
How to read the estimate
The divorce cost calculator combines a base range for each type of case with multipliers for children and complex assets. Those ranges are planning estimates, not survey data, so use them to compare scenarios rather than to predict a bill. The gap between an uncontested and a contested case is usually far bigger than any difference between areas or lawyers. Ask any attorney you consult for a written fee agreement, their hourly rate, the retainer and an estimate for your type of case, then compare it with the divorce cost calculator range. Fees can rise sharply once a case goes to trial, so ask about that too.
