Contract Paralegal vs. In-House Hire: The Real Math for a Small PI Firm

A year into this blog, it's time for the post that the whole "Working With a Freelance Paralegal" series has been building toward — the decision post. You've established that delegation is ethical (month one), billable (month four), and structurally necessary past a certain caseload (month six). The remaining question is form: contract support, or an employee?

I have an obvious interest in one answer, so this post earns its keep the only way it can: by doing the math honestly, including the part of the math where the right answer is hire someone, not me. That part exists. Let's find out which side of it your firm is on.

The full cost of the in-house hire (it isn't the salary)

The number everyone knows: an experienced litigation paralegal's salary, which in most markets runs somewhere in the $50–70K range, higher in major metros. The numbers people forget, stacked on top:

Employment costs. Payroll taxes, benefits, insurance, PTO coverage — conventionally another 25–35% on the base. A $58K paralegal is a $75K± line item before they touch a file.

Infrastructure. A workstation, software seats, payroll administration, and — in a small office — physical space.

Management. The invisible one. An employee is a standing relationship: training, supervision, reviews, the workflow of keeping someone productively busy. That's attorney time — your scarcest input, as the caseload post established — spent on management. Modest with a great hire; never zero.

Utilization risk. The structural one, and the one that decides most small-firm cases. You're buying ~2,000 hours a year whether the caseload generates them or not. PI work is spiky — case build-ups, discovery waves, trial pushes, then valleys. The hire sized for the peaks idles in the valleys at full cost; the one sized for the valleys drowns in the peaks, and you're back to midnight assembly work anyway.

All-in, a full-time experienced paralegal is realistically an $80–95K annual commitment — justified completely if the work is there.

The full cost of contract support (it isn't just the rate, either)

My side of the ledger, with the same honesty. The visible number: an hourly rate — mine is $65, $55 on volume retainer, published on the pricing page. The additions:

Engagement overhead. Defining assignments takes more deliberateness with a contractor than hollering down the hall. (Less than feared — a standing-instructions document amortizes most of it, and that system gets its own post — but it's real, and it's yours.)

Availability limits. A contractor serves multiple clients. Good ones manage scheduling professionally, but you don't own my Tuesday the way you'd own an employee's; genuine same-hour emergencies favor the desk down the hall.

No ambient presence. An in-house paralegal absorbs your firm's context continuously — overhears the client calls, knows the local clerk's quirks. A contractor knows what's in the file and the instructions. For defined deliverables this matters little; for "just handle whatever comes up," it matters a lot.

What you don't pay for: idle hours, benefits load, management time at scale, or capacity you didn't use. Cost tracks work, to the invoice line.

The threshold math

So the decision reduces to one variable: how many paralegal-hours does your caseload actually generate, sustained?

The arithmetic: an $85K all-in hire, against contract support at $55–65/hour, breaks even somewhere around 1,300–1,500 contract hours a year — roughly 25–30 hours every week, year-round. Below that line, the contract model wins on cost alone, before counting the utilization risk you're not carrying. Above it — sustained, not seasonal — the employee wins on cost and presence, and you should hire. A solo carrying 30–40 active PI files typically generates real paralegal demand in the 10–20 hour/week band with spikes — under the line. A two-attorney shop pushing heavy litigation volume crosses it. If your honest weekly number starts with a 3, start interviewing. I mean that.

The hybrid path (what growing firms actually do)

Here's the move the binary framing hides, and the most useful paragraph in this post: contract support is also how you find out your number. Six months of engagement invoices is a precise, file-by-file measurement of the paralegal demand your caseload really generates — data no estimate matches. Firms that grow deliberately often run exactly this sequence: contract support to relieve the ceiling now → invoices accumulate into a business case → in-house hire made confidently when the data clears the threshold → contract support retained for spikes and trial pushes, since the hire sized for steady-state still needs surge capacity.

In that sequence there's no versus at all. The contract phase de-risks the hire; the hire doesn't end the relationship, it right-sizes it. Some of my longest-running attorney relationships are with offices that hired in-house years ago — I'm the trial-season gear they shift into.

The decision, summarized

Under ~25 sustained hours/week of real paralegal demand: contract, and bank the difference. Over ~30, sustained: hire, sincerely. In between, or unsure: run the hybrid — start contract, let the invoices measure it, decide on data. Whichever side of the math you land on, the year-one conclusion of this series stands:

The expensive option isn't the contractor or the employee. It's the attorney doing paralegal work at attorney rates — the one arrangement with no defenders left.The year-one conclusion
