Billable hours are the time a lawyer spends on client work that the firm records so it can charge for it — the unit hourly billing runs on, and at the firms that set formal targets, the number behind year-end bonuses and raises.
This page explains what counts as a billable hour, how time is recorded in tenths, what annual targets look like by firm type, and what happens when you fall short.
What counts as a billable hour
A billable hour is an hour of work on a client matter that a lawyer records so the firm can charge a client for it.
The dividing line is whose matter the time serves.
Drafting a motion, reviewing a contract or taking a client's call produces billable time.
Training, internal meetings, business development and firm administration do not, because those costs belong to running the firm rather than to any client's matter.
Two distinctions matter for reading your own numbers.
Billable is not the same as worked: an eight-hour day at the office can produce far fewer billable hours.
And recorded is not the same as paid: time you log can be written down on an invoice or never collected — the funnel this page walks through below.
The billable hour is also not the universal measuring stick.
Where clients pay flat fees or contingency fees, or in salaried government and public-interest roles, there may be no client hours to bill at all.
Hour targets are a feature of hourly billing, and where a firm sets one, it shapes the working year.
How time is recorded
Under hourly billing, time is recorded in tenths of an hour: each tenth is six minutes, and a time entry counts a task in those units.
A 12-minute phone call is two tenths.
A 48-minute research memo is eight tenths.
An entry describes the task in a short narrative, because the client's invoice is built from these lines.
Narratives matter more than they look.
"Work on matter" invites questions; "draft summary judgment motion" tells the client what the time bought.
Record entries as work happens or shortly after — reconstructing a week from memory on Friday afternoon loses the short calls and quick reviews that add up, along with the detail that makes an invoice defensible.
The running total is the point of the discipline.
A firm that sets an annual target measures it on this recorded time, which is why a 2,000-hour expectation and a 2,000-hour work year are different things — a distinction the arithmetic below makes concrete.
Typical annual billable targets by firm type
Start with what the record does and does not show.
For associates at large firms, our research found no NALP or similar primary statistic for what the average BigLaw associate bills.
What our research did find is the hour expectations reported for the 2026 market-scale raises.
According to Above the Law's associate compensation scorecard, which reports firm memos, firms that matched Milbank's 2026 raise commonly tie the scale to a 1,900- or 2,000-hour billable expectation: the scorecard lists Norton Rose Fulbright at 1,900 hours, McDermott and Quinn Emanuel at 2,000, and no hours for Milbank.
That is secondary reporting on a set of firm memos — read it as describing those firms' terms, not as an industry-wide standard.
At smaller firms, no comparable target data exists in our research; the closest is outcome data on what firms actually recorded, covered below.
And where clients are not billed hourly — government, public interest, in-house legal departments — a billable-hour target is not the natural measure, so expectations are set on other bases.
The practical takeaway: a target is set by the employer that pays it, so ask for the number directly in interviews — it is a normal question, and the answer shapes the job more than most salary details.
The attorney career guide maps how these settings differ across a career.
What 2,000 billable hours means in a real week
Take the 2,000-hour figure that appears in the market-scale firm memos above and do the arithmetic — our math, not a sourced figure.
Spread across all 52 weeks with no days off, 2,000 hours is more than 38 recorded hours every week.
Spread over 50 working weeks — assuming four weeks away — it is exactly 40 recorded hours a week: a full eight billable hours every workday.
That last number is the reality check.
Eight billable hours a day means every working hour is a client charge — no email triage, no training, no admin, no internal meeting counting toward the target.
Against the 38% utilization Clio measured at the firms it studies — five hours of a lawyer's day goes unbilled, in the report's own framing — a target-level day is a different shape from a normal recorded day, and that gap is why a target year demands deliberate timekeeping rather than ordinary diligence.
One boundary keeps the number honest: the target counts recorded billable time, never hours spent in the building.
Two lawyers at the same desk for the same hours can finish a year with very different totals, and the firm's formulas read the recorded number, not the wall clock.
Billed vs collected hours
Recorded hours are the first stage of a funnel, and Clio's 2025 Legal Trends Report provides the vocabulary for the stages.
Utilization is the share of an eight-hour day spent on billable work.
Realization is the share of that billable work that actually gets invoiced.
Collection is the share of invoiced work that gets paid.
Clio's report puts averages on all three for the firms in its sample:
| Stage | What it measures | Clio 2025 average |
|---|---|---|
| Utilization | Share of an 8-hour day spent on billable work | 38% — five hours of the day unbilled |
| Realization | Share of billable work invoiced | 88% — 2.6 hours invoiced per day |
| Collection | Share of invoiced work paid | 93% — 2.4 hours collected per day |
Read top to bottom, the funnel shrinks: of the hours in a day, a share becomes billable time; of the billable time, a share reaches client bills; of the billed work, a share is collected.
For an individual lawyer the practical meaning is control: the recorded total is the stage you directly own, while what gets invoiced and paid reflects billing partners, write-downs and clients' payment behavior after the fact.
What the Clio figures do and don't describe
How hours affect bonuses and partnership
Where targets exist, hours reach pay through two doors.
The base: per the Above the Law scorecard, firms that matched Milbank's 2026 raise commonly attach a 1,900- or 2,000-hour expectation to the scale, so the salary and the hours travel together.
The bonus: per the ABA Journal's November 2025 reporting on the 2025 bonus season, Cadwalader paid 120% of the year-end bonus to associates with at least 2,200 billable hours in 2025.
Both figures are secondary press reporting, so read them as examples of the linkage rather than a market formula — bonus structures are firm-specific.
The 2026 year-end BigLaw bonus amounts had not been announced as of the sources read for this page (October 2, 2026).
Partnership is the longer horizon.
Recorded hours are a quantified, year-over-year record of an associate's production — the kind of number the bonus and scale memos above are built on.
How a given firm weighs hours against client development, work quality and the rest of a partner case is firm-specific; our research found no public source that documents the weighing — the partner-track guide covers that path separately.
What happens if you miss your target
There is no single answer, because consequences are set by each firm's own policies.
What the documented examples show is firms that hard-wire hours into pay — the 120% Cadwalader bonus tier is the clearest — so at a firm structured that way, missing the hours target translates directly into a smaller bonus.
Where the target is one input in a broader review, a shortfall becomes a number your firm watches and a conversation worth having before year end rather than after.
If you are heading into a target year, three habits do most of the work.
Record time as work happens, so short tasks survive the week.
Know your run rate: the target divided by the weeks you plan to work is the weekly number to hold.
And if you fall behind, raise it mid-year with the partner assigning your work — the recorded total is the one input you control directly.
