You're Probably Underestimating Your Costs
While I’m not a veterinarian, and you definitely don’t want me performing anything clinical, I imagine that when you go into surgery, you don’t just wing it. You’ve reviewed the case. You know what you’re working with, what success looks like, and you’ve already thought through what happens if something unexpected comes up. The plan exists before the first incision.
Managing the financial side of a veterinary practice works the same way. Before you commit time, capital, and energy to a new enterprise or a major operational change, you want to have worked through it on paper first. That’s the whole idea behind planning budgets, and agricultural economists have been refining these tools for decades.
There are four planning budgets that agricultural economists recognize, and it’s worth knowing what each one is for, even briefly. A cash flow budget maps the timing of money moving in and out of an operation. Not just whether you’ll be profitable, but whether you’ll have cash available when bills come due. A partial budget is built for smaller, contained decisions: should I buy this equipment or keep custom hiring? Add this service? It only evaluates what changes and holds everything else constant. A whole farm budget zooms all the way out and is the tool you reach for when a proposed change is big enough to reshape the entire operation, like taking on a new facility or bringing in a partner.
Those three all have their place. But the fourth one is the enterprise budget. This is where things get interesting, and it’s the one I want to spend the rest of this issue focusing on. I think it’s time that veterinary medicine uses enterprise budgets more often, because they are the most useful for figuring out how to optimize the planning of your business.
An enterprise budget is a bottom-up analysis of a single activity within a larger operation, built on a per-unit-of-production basis (per acre, head of livestock, or procedure). The idea is to isolate one thing you do (or are thinking about doing) and ask: Does this pay? What makes this distinct from a simple profit-and-loss calculation is that it’s built to capture the full economic cost of a decision, not just the accounting cost. That distinction matters more than it might sound at first.
When you sit down to build an enterprise budget, you start with revenues. Every stream of income the enterprise generates, with realistic price and quantity assumptions attached. Then you work through costs in two layers. The first layer is variable costs, sometimes called operating costs: the inputs you consume to produce the thing, such as labor, supplies, and medications. These costs exist because you chose to produce; they go away if you stop. The second layer is fixed costs, or overhead that you’re on the hook for regardless of what happens in a given production period, such as machinery depreciation, land, buildings, insurance, and taxes. Agricultural economists have a useful shorthand for these: the DIRTI-5, standing for Depreciation, Interest, Rent, Taxes, and Insurance.
Once you have revenues and costs laid out, you calculate net return… but you actually calculate it twice, and both numbers mean something different. Returns above variable costs tell you whether the enterprise can survive in the short run, whether it’s at least generating enough revenue to cover what was spent to produce it. Returns above total costs tell you whether it’s viable over the long haul, with everything included. A business can limp along with negative returns above total costs for a while, but not forever.
Here’s where enterprise budgets get philosophically interesting, and where they depart from how most people informally think about profitability. A rigorous enterprise budget doesn’t just count the dollars you spend. It accounts for opportunity costs…you know that concept we keep talking about in almost every article now? But in this case, we can think about it as the value of the next-best thing you could have done with those same resources. This shows up in a few specific places that tend to get glossed over in informal financial thinking.
Owner labor is one. Many practice owners significantly undercount the value of their own time when assessing whether something is profitable. If you’re putting in forty hours a week managing an enterprise, that time has a market value. A well-constructed enterprise budget puts a number on it. Similarly, a management fee, typically around five percent of gross revenues, represents the return to your judgment, your organizational capacity, your decision-making..
Property is another. If you own the land and building on which your practice is operating, you might be tempted to treat the cost as zero because you’re not writing a rent check. But that land could be leased to someone else. The opportunity cost of using it yourself is the rent you’re foregoing. A complete enterprise budget captures that.
Once you’ve built a budget with true economic costs included, you can calculate something genuinely useful: break-even prices and production. The short-run break-even price— variable costs divided by production quantity — is the floor below which you’re losing money on every unit produced and should stop. The long-run break-even price — total costs divided by production quantity — is the floor below which the enterprise isn’t sustainable, full stop. This tells you exactly how much margin for error you have.
Agricultural economists have been building enterprise budgets for corn, soybeans, cow-calf operations, and poultry flocks for generations. Land-grant extension programs publish them freely. Lenders expect them. Beginning farmers are taught to build them before they’re taught much else about financial management. Veterinary medicine, as an industry, largely hasn’t adopted the tool, however, and I think that’s a missed opportunity.
Consider what a practice owner actually faces when evaluating a new service line. Should we add ultrasound? Expand into reproduction services? Offer a wellness plan? These decisions get made, but they often get made on intuition. An enterprise budget forces a more complete conversation. What’s the realistic revenue per procedure, and at what volume? What are the true variable costs — consumables, technician time, and the veterinarian’s time at its real market value? What fixed costs need to be allocated — the equipment depreciation, the additional insurance, the square footage? And critically: what’s the break-even procedure volume at realistic pricing, and is that volume actually achievable in your market?
Those questions have answers. They just require a structured tool to surface them. This isn’t a criticism of how veterinary practices are managed. But the enterprise budget framework is mature, well-documented, and freely available. It translates cleanly from a row crop to a dental service line. The logic is identical. Only the line items change.
Planning budgets, and enterprise budgets in particular, exist because decisions made on paper are cheaper than decisions made in the field. They force you to articulate your assumptions, confront your costs honestly, and stress-test your plan before the first dollar is spent. They make implicit trade-offs explicit. And they give you a shared language for talking through a decision with a lender, a partner, or your own skeptical inner voice.
Veterinary medicine is full of smart, analytically capable people who think carefully about complex problems every day. The enterprise budget is just one more tool for doing that, applied to the business rather than the patient. It’s worth knowing how to use it. And if you want to know more about them, or need help building one, you always have me in your corner to call!
