Criminal Defense Cost Calculator

Attorney fees from case type and complexity.

About this calculator

This calculator builds an attorney-fee estimate by combining three independent multipliers against a base fee anchored to the type of criminal charge. The base fee ranges from $4,000 for a drug possession case up to $50,000 for a homicide charge, reflecting national median fee-survey data for a moderate-complexity plea. That base is then multiplied by a complexity factor (0.6x for simple facts up to 3.0x for highly complex cases needing extensive discovery), an attorney-tier factor (public defenders are free at 0x; large or prestigious firms run 3.5x a solo practitioner's rate), and a jurisdiction cost index you set directly to reflect regional cost-of-living differences. If the case is expected to go to trial rather than resolve in a plea, the calculator applies a further 2.5x multiplier on top of everything else, capturing how dramatically trial preparation — voir dire, expert testimony, extended motion practice — inflates legal costs compared to a negotiated plea.

Expert witness costs are priced separately at roughly $5,000 per witness (scaled by the same jurisdiction index) and investigation costs are estimated as 15% of total attorney fees. Court costs and filing fees are a flat estimate that jumps from $500 to $2,500 if trial is expected, reflecting the added transcript, jury, and administrative costs a trial generates. The tool also back-calculates an implied hours estimate by dividing total attorney fees by each tier's typical hourly rate, and reports the federal public-defender income-eligibility threshold (125% of the federal poverty line) as a reference point. Actual attorney fees vary enormously by individual practitioner, region, and negotiating leverage — always get multiple quotes rather than relying solely on this estimate.

How to Use This Calculator
  1. Select Case Type from the list (DUI/DWI, drug possession, assault, theft/fraud, domestic violence, sex offense, homicide, or white collar/federal).
  2. Set Case Complexity and Attorney Tier (public defender, mid-range, or top-tier private counsel).
  3. Indicate whether Trial is Expected and Expert Witnesses are needed.
  4. Set Jurisdiction Cost Index for your region — major metro areas cost more than rural jurisdictions.
  5. Review Total Estimated Cost including attorney fees, investigation, and expert witnesses.
  6. Get multiple quotes from attorneys — fees vary widely even for similar cases.

What each input means

Case Type
0=DUI/DWI, 1=Drug possession, 2=Assault, 3=Theft/fraud, 4=Domestic violence, 5=Sex offense, 6=Homicide, 7=White collar/federal.
Case Complexity
How complicated the case is — more complexity means more attorney hours.
Attorney Tier
The level of legal representation, which drives hourly rate and fee multiplier.
Trial Expected
Whether the case is expected to go to trial rather than end in a plea bargain — trial significantly increases costs.
Expert Witnesses Needed
Number of expert witnesses (forensic, medical, psychological, etc.).
Jurisdiction Cost Index
Cost-of-living adjustment: 0.5=rural/low cost, 1.0=national average, 1.5=major city, 2.0=NYC/SF.

Frequently Asked Questions

In what order do Complexity, Attorney Tier, and Jurisdiction Cost Index combine?

All three are multiplied straight into the case-type base fee at once: attorney fees = base fee x complexity multiplier x attorney-tier multiplier x jurisdiction cost index. Because they multiply rather than add, choosing a top-tier firm (3.5x) in a highly complex case (3.0x) in an expensive jurisdiction (2.0x) compounds into a total more than 20 times the base fee, not just the sum of the three factors.

Why does expecting a trial multiply the cost by 2.5x instead of adding a flat surcharge?

The 2.5x trial multiplier is applied to the already-combined attorney fee (after complexity, tier, and jurisdiction are factored in), not to the raw case-type base fee. That means the trial premium scales with everything else — a complex, high-tier trial case sees a much larger dollar increase from that multiplier than a simple, low-tier one, even though the multiplier itself is the same 2.5x in both cases.

Why does Estimated Attorney Hours show 0 when I select a public defender?

That figure is back-calculated by dividing total attorney fees by the tier's hourly rate, and public defenders are modeled with both a 0x fee multiplier and a $0 hourly rate — since they're appointed and don't bill by the hour in the usual sense. With a zero rate, the calculator skips the division and reports 0 hours rather than dividing by zero.

How is the Public Defender Income Limit figured?

It's set at 125% of the federal poverty guideline for an individual, using the 2024 figure of $15,060 as the base — so the threshold reported is a flat reference number rather than one derived from your other inputs, and it doesn't adjust for household size or the specific state's own income cutoff for appointed counsel.
