Understanding the Business You're Really In — Part 4

The Costs You Never See

By Eric R. McQuiston, PLA

Some years ago I was having lunch at a trade event with a young contractor just getting started who was frustrated that, on paper at least, the project had gone exactly as planned. Crew showed up, materials arrived, the client was thrilled. And yet when he pulled out his actual cost sheet, something didn't add up. He'd priced his labor at $25 an hour, paid his guys $25 an hour, and somehow still came up short. He looked at me like I'd hidden money from him somewhere in the mulch pile.

I hadn't. He'd just never been shown the difference between what something costs to buy and what it actually costs your business.

Back in the first article of this series, we broke direct costs into four simple categories — labor, equipment, materials, and subcontractors. That's still entirely correct. But there's a layer underneath those four categories that most contractors never learn, and it's exactly what tripped up that cost sheet over lunch that day. Before those four categories become part of your real direct costs, they need to be adjusted to reflect reality. That's where cost modifiers and contingency come in — and no, they're not a sneaky fifth bucket. They just make sure your existing bucket is telling you the truth.

Start with the Base Cost

Every direct cost starts life as a base number. An employee earns $25 an hour. A pallet of pavers runs $850. A skid steer rents for $250 a day. A subcontractor quotes you $4,500. Those numbers feel solid, real, easy to plug into an estimate — and they're exactly why so many contractors get burned. They're a starting point, not the truth.

Now, don't lose sight of what we covered in the second article — those base numbers still get marked up to recover your Overhead, the same way we discussed. That part hasn't changed. And if you remember the third article, this cuts even deeper than a supplier invoice: if you're finally paying yourself an honest wage for the work you do, as we talked about, that wage deserves the exact same closer look every other hourly rate in this article is about to get. What we're adding here is a step that happens before that markup ever occurs: making sure the base number itself is accurate in the first place. Because more often than not, that $25-an-hour employee or that $250-a-day skid steer costs your business quite a bit more than the number on the invoice suggests — and if you mark up a number that was wrong to begin with, you're just recovering overhead on a lie. Before any of those base numbers become part of your actual direct costs, they need a closer look.

Cost Modifiers: What Things Really Cost You

I call this a cost modifier because that's precisely what it does — it adjusts a base number until it reflects what a resource actually costs your business to use, not just what it costs to acquire. Most contractors already do something similar when they adjust a bid for a job that's farther away, harder to access, or sitting on tricky soil. This works the same way, except we're modifying the cost of the resource itself, not the project.

Labor is the clearest example. That $25-an-hour employee looks simple until you stack payroll taxes, workers' comp, general liability allocation, benefits, paid holidays, vacation, training, uniforms, recruiting costs, and the inevitable stretch of unproductive time onto that hourly figure. Add it all up, and that employee costs considerably more than their paycheck suggests — which is precisely the gap that tripped up my friend that day at lunch.

Equipment follows the same logic. The purchase price or rental rate is just the entry fee. Fuel, maintenance, repairs, insurance, transportation, licensing, storage, replacement reserves, and downtime all pile on top before you get to what that machine truly costs to own and operate.

Materials aren't exempt either. Beyond the supplier's invoice, you're absorbing freight, delivery, handling, waste, damage, warranty costs, storage, and inventory carrying costs — all quietly riding along with every material that shows up on site.

None of this creates a new financial category. It doesn't become overhead, and it certainly isn't profit. It simply makes sure your direct costs reflect what labor, equipment, materials, and subcontractors actually cost you — not what they cost on the invoice.

Contingency: Planning for the Inevitable

Once I've nailed down the true cost of each category, I generally add a contingency on top — somewhere around ten percent, though the right number depends entirely on the type of work you do and how much uncertainty comes with it. Like cost modifiers, contingency gets applied to costs, never to profit.

Contingency simply admits what every contractor already knows in their bones: construction doesn't go exactly to plan. Equipment breaks. Weather delays a crew for three days straight. Materials show up damaged, or don't show up at all. Someone gets sick during your busiest week. A client decides, halfway through, that the patio really should be six inches wider. None of that is unusual — it's just Tuesday in this business. Contingency accounts for that reality before it becomes a financial surprise, instead of after.

And to be clear: contingency isn't profit in disguise. It's not padding, and it's not a slush fund with a nicer name. Some projects eat every dollar of it. Others barely touch it. That unpredictability is exactly why it exists in the first place.

When Everything Goes Right

Every so often, the stars align. The weather cooperates, the crew has a great week, the equipment doesn't so much as hiccup, materials arrive on schedule, and the client makes decisions without agonizing over them for two weeks. When that happens, some or all of your contingency goes unused — and you get to decide what happens next.

You could simply keep it, letting it offset the next project where something inevitably goes sideways. That's a perfectly reasonable choice. But over the years, I've found a different move to be even more rewarding: share a piece of that good fortune with the client.

Maybe that means upgrading a specimen tree, adding a small lighting feature, tossing in a decorative container, offering a maintenance coupon, applying a modest credit to the final invoice, or simply sending a thoughtful thank-you. None of it is expected — which is exactly why it sticks. Clients rarely remember every plant you installed, but they almost always remember being treated generously when they didn't have to be. That kind of gesture builds trust, earns referrals, and quietly becomes part of your company's reputation long after the mulch has settled.

Closing Thoughts

Throughout this series, we've kept coming back to the same three buckets — Direct Costs, Overhead, and Profit. That framework never changes. Cost modifiers and contingency don't add a fourth bucket to the list; they simply make sure the Direct Costs bucket is telling you the truth about what labor, equipment, materials, and subcontractors really cost before that number ever becomes part of your pricing.

The better you understand your true costs, the better you understand your business — and the fewer surprises you'll find waiting for you on the next cost sheet you pull out over lunch.

I hope this series has been helpful — or at the very least, has you looking at your year-end statement with a little less confusion and a little more clarity. I'd genuinely welcome your thoughts, questions, or the "here's where this hit home for me" stories. That's usually where the best conversations start.

On a related note: I'm currently developing a simple, standalone business modeling application — no subscriptions, no strings attached — built specifically to let you run different scenarios for your own company. Adjust your overhead recovery, test a different markup split, see what happens if you finally pay yourself what the work is actually worth. If that sounds like something you'd find useful, subscribe below or reach out to me directly by email. I'd love to hear from you.

Best wishes, Eric
