How many paralegals and assistants does each attorney need?

Practice-area framing is where this question goes first — what do personal injury, family, estate planning and defense firms run? — and it is where the answer has to start with what we could not verify.

We looked for a primary or credential-body source for attorney-to-paralegal and attorney-to-staff ratios, by practice area or by firm size, and found none.

We found no source for a "typical" law firm org chart either.

The tidy per-attorney numbers that circulate in blog posts and software guides did not survive verification: we found no primary source behind any of them, so none appears on this page — and we will not credit one to Clio, the Association of Legal Administrators or Altman Weil.

The closest thing to industry survey data we located is the ALA's Compensation and Benefits Survey, which is distributed to members and which we could not read.

If you want an outside number, that members-only survey is where the industry's own data may live — check it directly rather than trusting a secondhand ratio.

Practice area still belongs in the staffing decision, just not as a copied answer.

It changes the inputs you count: a high-volume matter mix makes different demands on staff than a low-volume, document-heavy one.

The workable version of the practice-area question is an inventory of your own matters — for each matter type you handle, count what a month actually produces: new matters opened, documents drafted, filings made, client contacts handled.

Then mark which of those tasks require a licensed attorney and which trained staff can carry under a lawyer's supervision.

Your ratio lives in that list; the practice-area label is only a hint about what the list will look like.

Ratios are one input among many in hiring for your law firm — the rest of the employer picture, from role definitions to supervision rules, lives in our hiring hub.

Start from attorney capacity, because staff exists to multiply it.

The number that matters is your firm's own billable-hour expectation, not an industry average — and on averages, the honest result of our research is that no single verified figure exists for large firms.

What is on record is narrow: market-scale firms that matched Milbank's 2026 raise commonly tie the scale to a 1,900- or 2,000-hour billable expectation — reporting compiled by Above the Law's associate-compensation scorecard has Norton Rose Fulbright at 1,900 hours and McDermott and Quinn Emanuel at 2,000, with Milbank's memo listing none.

That is press reporting of firm memos, not a verified benchmark.

Your firm's own written expectation is the number to staff against.

Three rates then tell you where attorney time actually goes.

Clio's 2025 Legal Trends Report defines them precisely: utilization is the share of an eight-hour day spent on billable work, realization is the share of billable work invoiced, and collection is the share of invoiced work paid.

Across firms on its platform, the report puts average utilization at 38% of an eight-hour day, with realization at 88% (2.6 hours invoiced per eight-hour day) and collection at 93% (2.4 hours collected per day).

Mind the scope before you plan around those figures: they are averages for firms that run on Clio's platform, a sample weighted toward solo and small firms, and they are not a big-firm benchmark.

Use them as categories, not levels — measure your own three rates and read which one is broken.

Strong utilization with weak realization says the leak is in invoicing; realization without collection says the leak is in getting paid.

The fee model decides which of the three rates carries the money, so let it shape the staffing math.

In an hourly practice, staff leverage shows up in utilization and realization; where fees arrive on outcome, the collection rate is the one that has to cover the payroll.

And where a court awards fees under 42 U.S.C.

1988, delegated staff time can be compensated at market rates — that is under leverage below.

No source hands you a headcount trigger — the same verification gap that hides ratios hides thresholds.

What you can read instead are the queues, and the queues are visible in three places you already have: the task inventory from the practice-area section above, your own three funnel rates, and the work your attorneys are doing that your matter mix did not actually require a lawyer for.

When recurring non-lawyer tasks queue up behind licensed attorneys — intake calls waiting, drafts waiting, filings waiting — that is the shape of a staffing gap, whatever the headcount math says.

Which role answers which queue follows from the inventory.

Intake staff absorb the front door when new matters arrive faster than attorneys can screen them; case managers move open matters through their recurring touchpoints; billing help is what a realization-and-collection gap points at.

Before you price any of them, price the hire correctly.

Our research found no primary source for a "fully loaded cost" multiplier for law-firm staff, so this page will not tell you to multiply salary by any figure.

Loaded cost is a calculation your firm runs: salary, plus payroll taxes, plus benefits, plus the software and space the role consumes.

Compute it from your own books — the multipliers quoted around the industry have no source we could verify.

For the salary line, the government series is the honest starting point.

BLS OEWS May 2025 puts the national median annual wage for paralegals and legal assistants (SOC 23-2011) at $62,890 — $30.24 an hour — with a 10th percentile of $44,740 and a 90th percentile of $101,500: the outer points of what employers reported, not a junior-to-senior ladder.

Legal secretaries and administrative assistants (SOC 43-6012) had a national median of $55,570 ($26.72 an hour).

Inside the legal services industry specifically, paralegals and legal assistants had a median annual wage of $61,770.

Two scope notes keep those figures honest: BLS combines paralegals and legal assistants into one occupation, so the data cannot split them, and the OEWS series excludes the self-employed — these are wage-and-salary workers, not contractors or firm owners.

Use the numbers as inputs to your loaded-cost calculation, not as offer letters.

One more cost asymmetry belongs in the add-staff math.

Under DOL regulations, paralegals and legal assistants generally do not qualify as exempt learned professionals, because an advanced specialized academic degree is not a standard prerequisite for the field — and job titles do not determine exemption status; duties and salary must meet the regulations.

A licensed lawyer who is actually engaged in the practice of law is treated differently: under 29 CFR 541.304, the federal salary-level and salary-basis requirements do not apply to that lawyer.

Confirm any classification with employment counsel before it goes into the budget.

Leverage is the firm-level version of the same arithmetic: how much fee-producing work each attorney hour anchors, and how much of the surrounding work trained staff carry.

The sourced economics of delegated work are more concrete than the ratio folklore.

In Missouri v. Jenkins (1989), the Supreme Court held that fee awards under 42 U.S.C.

1988 may compensate paralegal and law-clerk work at market rates rather than at the firm's cost — a court-recognized statement that, in those awards, delegated hours carry market value, not just cost.

The compensation side is where the model rules draw lines.

ABA Model Rule 5.4(a) bars a lawyer or law firm from sharing legal fees with a nonlawyer, subject to listed exceptions.

One exception matters here: 5.4(a)(3) allows a law firm to include nonlawyer employees in a compensation or retirement plan even if it is based in whole or in part on profit-sharing.

That is not permission to pay a paralegal or intake specialist a percentage of a specific case's fee or a per-signed-case bounty — those raise state ethics questions the model text does not answer.

Model Rule 5.4(b) also bars a lawyer from forming a partnership with a nonlawyer if any partnership activity is the practice of law.

Two framing notes keep this honest.

First, the Model Rules are model texts: the version that governs your firm is the one your state has adopted, and it can differ — confirm any compensation structure with your state bar's ethics counsel before you roll it out.

Second, we can cite no study linking staff ratios to firm profitability, so this page offers arithmetic, not a benchmark: your fee revenue per matter, your loaded staff cost, and your attorneys' capacity are the three lines that decide whether a hire pays for itself.

Treat any claim that a tool "replaces a hire" the way the first section treats circulating ratios: ask for the primary study, and note who produced it.

Our research holds no sourced figure for how much any software or AI product shifts a firm's staffing needs, so this page projects no software-adjusted ratio and no AI-driven headcount change.

What software genuinely changes is the task inventory, and the task inventory is the ratio's input.

When you adopt a tool, re-run the inventory from the practice-area section: which recurring tasks got faster or disappeared, which new tasks it created — someone has to check the tool's output — and where the saved hours actually landed.

The right response to automation is a changed list, measured the same way as before, not a number bought off a slide.

One duty does not shrink with the tooling: supervision.

Whatever a tool drafts, routes or decides, the lawyers remain responsible for the staff and vendors operating it — our guide to ABA Model Rule 5.3 on supervising nonlawyer staff walks through that duty, including how it reaches contractors, vendors and AI tools.

Employer information, not legal advice. Staffing and compensation structures raise state ethics questions, and overtime classification is employment law — confirm both with your state bar's ethics counsel and your employment counsel before you act.
