Contingency fees and settlement math: what comes off the top

The number that matters at the end of a case is not the settlement — it's the remittance: what actually reaches the client after the fee, the case costs, the liens, and sometimes the taxes. Every one of those deductions is governed by something — the retainer agreement, an ethics rule, a Supreme Court tax case — and the order in which they're computed can quietly move thousands of dollars from one side of the ledger to the other.

The anatomy of a contingency arrangement

A contingency fee trades hourly billing for a share of the outcome: the lawyer is paid a percentage of the recovery — commonly staged, with a lower rate for early settlement and a higher one if the case is tried or appealed — and typically advances the litigation costs. The claimant pays nothing if the case recovers nothing, though cost responsibility on a loss varies by agreement and state. The arrangement is regulated by ethics rules in every state, most modeled on ABA Model Rule 1.5: the fee must be reasonable, and per Minnesota's adoption of Rule 1.5(c) — language used nearly verbatim across jurisdictions — “a contingent fee agreement shall be in a writing signed by the client and shall state the method by which the fee is to be determined, including the percentage or percentages that shall accrue to the lawyer in the event of settlement, trial or appeal.”

The order-of-operations clause: the quiet five thousand dollars

The same rule requires the agreement to state the “litigation and other expenses to be deducted from the recovery; and whether such expenses are to be deducted before or after the contingent fee is calculated.” That clause decides the fee base, and the difference is not academic:

On a $300,000 settlement with $15,000 of advanced costs and a one-third fee: compute the fee first and it's $100,000, leaving the client $185,000 after costs. Deduct costs first and the fee is $95,000, leaving the client $190,000. The bigger the costs — experts, depositions, trial exhibits — the bigger the swing, which is why the clause deserves attention at signing rather than discovery at disbursement.

Settlement structure changes the fee base too

When a settlement includes future payments — a structured settlement — the fee is conventionally computed on the cost of funding the structure (what the annuity costs today), not on the face total of the future checks. A one-third fee on “$600,000 over twenty years” should be a third of the roughly $390,000 funding cost, not $200,000 off the top. Confirm which base the agreement uses before the mediation; the difference compounds every other number in the closing statement.

The tax trap in taxable cases

For physical-injury recoveries the fee question is painless — the whole recovery is excluded from income under section 104(a)(2), fee included. Taxable recoveries — employment claims, defamation, punitive damages — are harsher. In Commissioner v. Banks, 543 U.S. 426 (2005), the Supreme Court held that “when a litigant's recovery constitutes income, the litigant's income includes the portion of the recovery paid to the attorney as a contingent fee.” The client is taxed on money they never touched.

Whether an offsetting deduction rescues the result depends on the claim. Unlawful-discrimination and certain employment claims get an above-the-line deduction for the fee; many other taxable claims do not, leaving the client taxed on the gross while netting the net. The IRS's settlement-taxability guide is the starting point, and in a taxable case the after-tax remittance — not the settlement figure — is the only number worth negotiating toward.

Why divorce runs on different fees

Rule 1.5(d) draws a bright line: a lawyer may not charge “any fee in a domestic relations matter, the payment or amount of which is contingent upon the securing of a divorce or upon the amount of alimony or support, or property settlement in lieu thereof.” The policy is to keep counsel's incentives away from breaking up marriages or inflating support awards. The practical consequence for divorcing clients: the fee meter runs hourly, which changes settlement economics — every month of fighting over an alimony buyout or a QDRO has a fee cost that belongs in the decision about whether the fight is worth it.

The closing statement: check the arithmetic

At the end of a contingency matter the rule requires “a written statement stating the outcome of the matter and, if there is a recovery, showing the remittance to the client and the method of its determination.” Read it against the retainer: the percentage tier applied, the fee base, each itemized cost, and every lien — medical providers, insurers, and government payers routinely assert reimbursement rights that come out of the client's share. The remittance is where all of this guide's math converges; five minutes with the closing statement and a calculator is the cheapest audit in law.
