Can You Afford to Hire? The Financial Math Behind Your Firm's Growth

Every growing firm reaches the same moment. You are turning away work, or taking it and resenting it. Your evenings are gone. The obvious answer is to hire someone.

Then comes the hesitation, and it is usually the right instinct. Because the question is not whether you need help. You clearly do. The question is whether the firm can carry the cost of that help long enough for the hire to start paying for itself.

Most firm owners answer that question with a feeling. Here is how to answer it with numbers.

Start with the real cost, not the salary

The salary is the number you negotiate. It is not the number you pay.

Once you add employer payroll taxes, benefits, workers compensation, software licenses, malpractice coverage, myriad office supplies and license/continuing ed costs, and the physical or technical footprint of another person, the true annual cost typically lands somewhere between 1.25 and 1.4 times the base salary. A paralegal at sixty thousand realistically costs the firm seventy-five to eighty-four thousand.

Then add the costs nobody budgets for: recruiting time, onboarding, and the hours you will spend training instead of billing. That last one is real money, and in the first ninety days it is often the largest cost of all.

Write down the fully loaded annual number. That is your starting figure.

Ask what the role has to produce

Not every hire generates revenue directly, and that is fine. But every hire has to be justified by something measurable.

For a billable hire, the math is direct. Take the fully loaded cost, divide by realistic annual billable hours, and you get the hourly cost of that person. Then compare it to what you will actually collect for their time. Note the word collected. Not billed. If your realization rate is 85 percent, an associate billing at 250 is bringing in roughly 212, and the math has to work at 212.

Be conservative on hours. A new associate will not hit your target in year one. Plan for sixty to seventy percent of full productivity in the first six months.

For a non-billable hire, such as an administrator or an intake coordinator, the math runs through the hours they free up. If a legal assistant costs seventy thousand fully loaded and gives you back eight hours a week of your own billable time, that is roughly four hundred hours a year at your rate. Run the number honestly. If those recovered hours will go to catching up on email rather than to billable work, the hire does not pay for itself, and you should know that before you make it.

Layer the hire onto your break-even

This is the step most firms skip. A new hire does not just need to cover itself. It raises the floor for the entire firm.

If you know your break-even point, add the fully loaded monthly cost of the hire to it. That new number is what the firm must collect every month from the day the person starts. Look at your last twelve months of collections and ask a simple question: how many of those months cleared the new line?

If the answer is most of them, you have room. If the answer is about half, you are betting the firm's stability on the hire performing immediately, which they will not.

Check the cash, not just the profit

Profit and cash are different things, and hiring is where that difference bites hardest. Payroll runs every two weeks. Your clients pay in forty-five, sixty, or ninety days.

Before hiring, look at your cash reserve and confirm you can cover at least four to six months of the new position without counting on any revenue the hire brings in. That is your ramp runway. If it does not exist, the hire is not unaffordable forever. It is unaffordable this quarter.

Two questions worth settling first

What kind of work will they take? Look at your matter-level profitability before you decide. Hiring someone to absorb more of your least profitable work will make the firm busier and no more profitable. Hire toward the work that earns.

Employee or contractor? This is not a cost-saving decision to make casually. Getting it wrong carries real exposure, and the distinction is governed by the nature of the work, not by preference. The classification guide walks through the standards.

When the answer is not yet

Sometimes the numbers say wait, and that is useful information rather than bad news. Not yet usually means one of three things: raise rates, collect faster, or narrow the work you take. Firms that fix those first often discover the hire becomes comfortably affordable within two quarters, and they hire from strength instead of desperation.

Growth decisions like this are exactly where financial visibility stops being abstract. The firms that scale well are not the ones that guess bravely. They are the ones that ran the numbers first.
