Attorney Contingency Fee Calculator - Expected Value Analysis

Quick Answer

Contingency fee cases typically pay 33% of settlement/judgment to the attorney, meaning a $300,000 settlement generates $99,000 in gross attorney fees before expenses. Analyzing case value requires assessing settlement probability, time investment, overhead costs, and opportunity cost—most successful contingency practices require careful case selection to maintain profitability.

How Are Contingency Fees Structured in Legal Practice?

Contingency fees allow clients to pursue lawsuits without upfront attorney payment; instead, attorneys take a percentage of the final settlement or judgment.[1] Standard contingency percentages range from 25% to 40% depending on case type, jurisdiction, and complexity.

Most personal injury cases use 33% (one-third) contingency fees, while complex commercial litigation may command 40-45%.[2] The percentage may increase if the case goes to trial rather than settling—for example, 33% on settlement but 40% on judgment.

What Costs Reduce Attorney Contingency Fee Income?

Contingency fee attorneys typically advance case expenses (expert witnesses, court fees, discovery, investigation) out of pocket, recouping them from the settlement or judgment.[3] These costs can range from $5,000 for straightforward cases to $50,000+ for complex litigation.

If a $300,000 settlement required $20,000 in expenses, the attorney receives: ($300,000 × 0.33) - $20,000 = $79,000 net. This cost reality means many marginal cases become unprofitable after factoring in attorney time and expenses.

How Do You Calculate True Hourly Rate on Contingency Cases?

True hourly rate on a contingency fee case requires dividing net attorney fees by total billable hours invested. A case generating $79,000 net that consumed 150 billable hours equals an effective hourly rate of approximately $527 per hour.

However, not all cases settle profitably. If 20% of taken cases result in zero recovery (lost cases), the effective hourly rate drops significantly. Taking a case with 50% settlement probability and 150 billable hours only generates $263.33 average hourly rate when accounting for potential loss.

What's the Impact of Settlement Probability on Case Value?

Settlement probability is critical to contingency fee analysis. A case with 75% settlement probability at $300,000 has an expected value of $225,000 ($300,000 × 0.75).[4] After 33% attorney fees and $20,000 expenses, the net expected value is approximately $59,000.

Cases with 50% settlement probability at $300,000 settlement have expected value of $150,000 to the client, or approximately $29,500 net to the attorney after fees and expenses. This makes case selection critical—taking high-probability cases is far more profitable than high-potential cases with low settlement probability.

How Should You Evaluate Cases for Contingency Fee Viability?

Successful contingency practices use strict case selection criteria. Most require minimum expected recovery of $100,000-200,000 after accounting for probability and expenses.[5] Cases with liability issues, difficult damages quantification, or unsympathetic clients should have significantly higher expected values to justify the risk.

A simple framework: (Settlement Amount × Settlement Probability × Attorney Fee %) - Estimated Expenses = Minimum acceptable case value. If this calculation yields less than your minimum required hourly equivalent ($200+ per hour), reject the case.

What's the Difference Between Contingency and Sliding Scale Fees?

Sliding scale fees increase the attorney percentage if the case goes to trial. For example: 33% if settled before mediation, 37.5% if settled after mediation, 40% if litigated to judgment.[6] This structure incentivizes settlement while compensating attorneys for trial risk.

Clients prefer sliding scales because it reduces their effective fee for quick settlements. Attorneys should ensure the trial percentage adequately reflects increased time commitment and risk.

How Does Expense Recovery Work in Contingency Cases?

Contingency agreements must specify whether expenses are deducted before or after calculating the attorney fee percentage.[7] Deducting before (fee calculated on net recovery) is more favorable to clients; deducting after is more favorable to attorneys.

Example: $300,000 settlement with $20,000 expenses

• Deduct before: ($300,000 - $20,000) × 0.33 = $92,400 attorney fees, $187,600 to client
• Deduct after: ($300,000 × 0.33) - $20,000 = $79,000 attorney fees, $221,000 to client

Clearly specify this in engagement letters to avoid disputes.

Should You Ever Take Loss Cases to Build Book of Business?

Taking an occasional loss case can build reputation and client relationships, but systematic underpricing is a path to insolvency.[8] Most successful contingency practices maintain strict profitability standards and turn down cases that don't meet financial criteria.

If you do accept a loss case, cap your investment (e.g., "I'll invest up to $10,000 in expenses"), then withdraw if the case isn't progressing well. Build book of business through referrals from satisfied clients, not by losing money on unprofitable cases.

What's the Relationship Between Case Value and Time Investment?

Some cases have high settlement values but require extensive attorney time, reducing effective hourly rates. Complex commercial litigation might settle for $500,000 but require 400+ billable hours, yielding only $412 per hour effective rate.

Conversely, straightforward personal injury cases might settle for $150,000 in 80 billable hours at $495 hourly rate (after fees and expenses). Time investment is as critical as settlement value in case selection.

Frequently Asked Questions

Q: Are contingency fees always 33%? A: No, they range from 25-45% depending on case complexity, jurisdiction, and whether the case settles or goes to trial. Personal injury cases typically use 33%, while other practice areas vary.

Q: Can you charge hourly fees in addition to contingency fees? A: Generally no—contingency and hourly fees are mutually exclusive. However, you can charge hourly for work outside the contingency agreement (e.g., separate legal issues).

Q: What if a client has insurance that covers some attorney fees? A: Insurance coverage doesn't typically change contingency arrangements. The attorney fee is owed from the settlement/judgment regardless of insurance proceeds.

Q: How do you handle cases that partially settle? A: Partially settled cases (settling some claims/defendants while others remain) require calculation of fees on the settled portion only. Document this carefully in settlement agreements.
