Where Does a Contingency Case's Margin Actually Go?

Where Does a Contingency Case's Margin Actually Go? Contingency

A contingent matter’s margin is the fee minus what the firm spent to earn it: internal time, unrecovered advances on other cases, lien negotiation, and the carry on costs advanced before disbursement. The fee on the settlement statement is the top line, and the leak is cash velocity.

What does a single contingent matter actually earn?

An hourly firm can read its leak from realization: the gap between the value of the time worked and what survived to the invoice. A contingent firm has no invoice to measure against. Typically nothing comes in until the matter resolves, and from the first dollar the firm advances to the day of disbursement, cash only goes out. That interval is cash velocity, and it is where a contingent firm loses money it never sees as a line item. A flat-fee firm leaks through margin when internal time outruns the fee; a contingent firm faces the same margin question with a longer clock, and cash leaving the firm the whole way.

A settlement statement makes the result look tidy. It shows a fee and a reimbursement of advanced costs, and a reader can mistake the whole recovery for firm revenue. What each line means and where its number comes from is covered in our post on what goes on a settlement disbursement statement. This post starts where that one ends, at the fee line, and asks what the matter cost to produce it.

The unit matters too. Our post on personal injury law firm profit margin looks at the firm as a whole. A firm-level margin can look healthy while matters that run long quietly earn less than the average suggests, and the decisions that move margin get made one matter at a time.

What takes margin out of one matter?

Advanced costs that come back. Filing fees, experts, and records are usually fronted by the firm and reimbursed from the settlement under the fee agreement. That reimbursement is a pass-through, so it adds nothing to margin, but the cash is gone from the firm for as long as the matter stays open. Our post on whether advanced client costs are an expense or an asset covers how the books treat them in the meantime.

Advanced costs that do not. When a matter resolves for less than the costs, or for nothing, whether the firm can recover its advances from the client depends on the fee agreement and the jurisdiction’s rules. Where it cannot, the advance is a loss, and it belongs to the portfolio. A matter-level view has to decide how to spread that loss across the matters that did pay, or it will flatter every winner.

Lien reductions. A negotiated lien reduction raises the client’s net. It costs the firm the time spent negotiating, which no invoice will ever recover, and some firms choose to reduce their own fee to close a gap with a client’s expectations. That choice comes straight out of margin — a cost no invoice will ever show. Our post on how to account for a medical lien reduction covers the bookkeeping.

Carry. Between filing and disbursement, advances sit as money the firm has laid out and not yet recovered. Someone funds that: operating cash, a credit line, or outside financing. Each has a cost, and the cost grows with the time the matter stays open. When operating cash funds the advances, the cost is an opportunity cost: no bank statement shows it, which is why it tends to go uncounted.

A worked example: the $80,000 fee

The numbers below are invented for arithmetic. They describe no real firm and are not typical of any matter.

A hypothetical matter settles for $240,000. The fee agreement calls for one-third, so the fee is $80,000. The firm advanced $18,000 in costs, which the settlement reimburses; that pass-through leaves margin untouched. Now count what it took to earn the fee:

  • Internal time on the matter, at the firm’s cost: $40,000.
  • Time spent negotiating liens, at cost: $5,000.
  • Carry on the advances: suppose the firm funded them from a credit line costing 10% a year, and the full $18,000 was outstanding for the two years the matter ran. That is $18,000 times 10% times two, or $3,600.
  • This matter’s share of advances the firm never recovered on other cases: $5,000.

The four add up to $53,600. Subtract that from the $80,000 fee and the matter’s margin is $26,400.

Look at where the $53,600 went. Time accounts for $45,000 of it — the part any timekeeping habit would capture. The remaining $8,600 is carry and shared losses, which appear on no timesheet and no single invoice. A firm that measures only time would report a margin of $35,000 and be $8,600 too optimistic on this one matter.

Now change one thing. The same matter, with the same fee and the same costs, takes four years to resolve. Carry doubles to $7,200, and margin falls to $22,800. (Internal time would probably rise as well; hold it constant here to isolate the effect of time.) The settlement statement shows an $80,000 fee in both versions. Only a matter-level view shows the difference, and only a firm that tracks the inputs can build one.

What this depends on

  • The fee agreement and your jurisdiction’s rules: whether costs come out before or after the fee is calculated, whether a client owes costs on a loss, and how liens are prioritized and reduced.
  • How the firm funds advances (operating cash, a credit line, or outside financing), since each carries a different cost of carry.
  • Whether internal time is recorded on contingent matters, and at what cost basis. Without it the cost side of a matter-level margin is a guess, and the basis is the firm’s decision.
  • How costs and lien outcomes are coded to matters in the books: by matter from the start, or reconstructed at settlement, and who does that work.

Which open matter has carried its advances longest?

The Contingency plan lists Contingency Insights (case profitability) among its features, with custom pricing. Any tool can report a matter’s margin only as accurately as the inputs the firm gives it: advances coded to the matter, time recorded at a cost basis the firm chose, lien outcomes recorded when they resolve, and a rule for spreading advances that were never recovered. Those inputs are the firm’s to supply.

Pick your longest-open matter. Do you know, in dollars and as of today, what it has cost you to carry it? If the answer is an estimate, the margin on that matter is an estimate too.
