How to Know Whether Your Law Firm Can Afford to Hire Someone

Why the Salary Number Is Not the Cost

The most common error in a hiring decision is budgeting only the wage. The wage is the visible number, but the total cost of a position includes several components that add meaningfully to what the firm actually spends each month. Overlooking them produces a hire that looks affordable in the planning stage and creates cash pressure within the first quarter.

The full cost of a hire includes the gross wage, employer-side payroll taxes, any health or other benefits the firm provides, equipment and software the role requires, and the owner's time to train and manage the new person. That last item is easy to undercount because it does not appear on an invoice. But if the owner spends four to six hours per week in the first two months managing onboarding, that time has a cost equal to the owner's hourly salary rate multiplied by those hours.

Components of the fully loaded cost

• Gross monthly wage
• Employer payroll taxes (FICA, FUTA, SUTA at applicable rates)
• Health, dental, or other benefits if offered
• Equipment: computer, phone, or specialized hardware
• Software licenses or seat additions
• Owner time to hire, train, and manage during ramp-up

Estimating the Return in Concrete Terms

A hire is an investment, and investments have expected returns. The return on a staff hire in a law firm can be expressed in one of two ways: the value of time the owner reclaims for billable or business development work, or the additional capacity the firm gains to serve clients without adding owner hours. Both can be estimated in dollar terms before the hire is made.

If the owner currently spends twelve hours per week on administrative tasks that a paralegal or legal assistant could handle, and those hours could instead be applied to billable work at the owner's billing rate, the value of that shift is computable. Multiply the recovered hours by the billing rate per hour and compare the result to the fully loaded monthly cost of the position. This is not a guarantee of outcome; it is a framework for deciding whether the math can work.

Checking Cash Runway Before Committing

Even a hire with a favorable cost-to-return ratio can create a cash problem if the firm does not have enough runway to carry the position while it ramps up. The ramp-up period is the time between the hire's start date and when they reach full, independent productivity. During that period, the firm is paying the full cost of the position while realizing less than the full expected return.

Cash runway is the number of months the firm can pay the fully loaded cost of the new position from existing cash or reserve, assuming collections remain at their current level. To calculate it, take the reserve balance above the minimum target and divide it by the fully loaded monthly cost of the position. If the result is three months or more and the expected ramp-up is shorter than that, the runway is adequate. If the result is less than the expected ramp-up period, the timing or the cost structure needs adjustment.

Setting a Review Date Before You Hire

Before making an offer, write down three things: the fully loaded monthly cost of the position, the specific value you expect it to produce and when, and the date you will review actual results against those expectations. The review date should fall at the end of the ramp-up period, not at the end of the fiscal year. By then, the hire has had enough time to demonstrate whether the expected return is materializing.

If the review shows the hire is producing the expected value, you have evidence to support expanding the role or making a similar hire. If it shows the hire is not producing the expected value, you have a defined decision point rather than an ongoing ambiguity. A review date set before hiring is how you keep a hiring decision from becoming an indefinite obligation.

The Pitfall of Hiring From Overwhelm

The pressure to hire is highest when the owner is most overwhelmed. But overwhelm is not the same as financial readiness. A period of high volume can produce the feeling that a new hire is urgently necessary, but if that volume is seasonal, project-based, or the result of a one-time client surge, the firm may not be able to sustain the cost of a permanent position after the peak passes.

Before hiring under pressure, ask whether the current workload is representative of what the firm will carry for the next twelve months. If the answer is uncertain, consider whether the immediate capacity need could be met with contract or part-time help during the peak, giving you more time to assess whether permanent headcount is justified. Permanent positions carry fixed costs that persist after the work that triggered the hire has ended.

Running the Hiring Analysis This Week

If you are considering a hire, build the three-column analysis this week. In the first column, list every component of the fully loaded monthly cost and total it. In the second column, estimate the specific monthly value the role is expected to produce, in recovered owner hours at the billing rate, in additional client capacity, or in a concrete operational improvement. In the third column, calculate how many months of runway the current reserve provides above its minimum target.

If the numbers support the hire, set the review date before making the offer. If the numbers reveal that the runway is short or the return is unclear, that is a useful finding before the cost is incurred, not after. The analysis takes less than an hour and produces a written record of the reasoning behind one of the most consequential recurring financial decisions in a small firm.

• List every component of the fully loaded monthly cost and total it.
• Estimate the specific monthly value the role produces in concrete terms.
• Calculate available runway: reserve above minimum divided by fully loaded monthly cost.
• Write down what success looks like at the end of the ramp-up period.
• Set a specific review date before making the offer.
