Stop guessing or copying your competitors. Here is the math, the operations, and the realistic scenarios for calculating a sustainable hourly rate that actually covers your costs and generates a profit.
If you ask an online forum or a local supplier, "what should I charge per hour as a contractor?", the most common answer you will hear is a variation of the "going rate." Someone will tell you they charge $85 an hour, or maybe $120, or even $150. The problem with adopting the going rate is that you are adopting someone else's financial structure without knowing if it works for your business. In many cases, the contractors setting the going rate are actually losing money slowly, subsidizing their business with unpaid weekend paperwork or ignoring equipment depreciation until a truck breaks down.
To figure out what you should charge, you must disconnect from the market rate temporarily and focus strictly on your own math. Your hourly rate needs to accomplish three specific things. First, it must pay your technicians (or yourself) a competitive wage. Second, it must cover all the hidden overhead costs of running a legitimate contracting business. Finally, it must generate a net profit margin that allows the business to grow, weather slow seasons, and provide a return on the risk you took by starting it.
We are going to break down the exact operational math required to calculate your true hourly cost, find your break-even point, and establish a profitable hourly rate.
The biggest mistake new contractors make is confusing their hourly pay rate with their hourly billing rate. If you want to take home $40 an hour, you cannot charge the customer $40, $50, or even $60 an hour and expect to survive. An hour of your time on site carries the financial weight of all the hours and expenses that happen off site.
You or your employees are not turning wrenches 40 hours a week. In service and contracting trades, a realistic utilization rate—the percentage of time actually billed to a job—often hovers between 50% and 60% for a highly optimized team, and can easily drop to 40% for solo operators who handle their own sales and admin.
Think about the unbillable hours. You have drive time between jobs, trips to the supply house, estimating and quoting, vehicle maintenance, customer phone calls, and administrative paperwork. If a technician works a 40-hour week but only 20 hours are billed to a customer, those 20 billable hours must carry the financial burden of the entire 40-hour payroll.
When calculating what you should charge per hour as a contractor, you must start with the fully burdened labor cost. This is the total cost to employ someone (or yourself), not just the hourly wage. Labor burden includes:
A typical labor burden adds 25% to 40% to the base wage. If you pay a technician $30 an hour, their burdened cost might be closer to $42 an hour. If their utilization rate is 50%, the cost of one billable hour of their time is now $84—and we haven't even touched business overhead yet.
Overhead consists of the expenses required to run your business regardless of whether you have work that day. This includes vehicle loans or leases, auto insurance, fuel, software subscriptions, office rent, marketing, accounting fees, cell phones, and administrative salaries (like a dispatcher or bookkeeper).
To apply overhead to your hourly rate, calculate your total annual overhead and divide it by the total number of billable hours you expect your company to produce in a year. For example, if your annual overhead is $60,000 and you operate solo with 1,000 billable hours a year, every billable hour must cover $60 in overhead costs.
Your break-even rate is the absolute minimum you can charge per hour without losing money. At this rate, all bills are paid, your salary is covered, but the business generates zero profit. Here is the operational formula to find your break-even rate:
Break-Even Hourly Rate = (Total Burdened Payroll + Total Overhead) / Total Billable Hours
Let's look at a concrete math scenario for a solo contractor. Assume you want a base salary of $70,000 per year. Your labor burden (taxes, insurance, benefits) adds 30%, making your total compensation cost $91,000. Your business overhead (truck, fuel, tools, software, marketing) is $35,000 a year.
Your total costs for the year are $126,000. If you work 50 weeks a year, 40 hours a week, that is 2,000 total hours. But you are realistic about utilization, estimating 50% billable efficiency. This leaves you with 1,000 billable hours.
Divide your total costs ($126,000) by your billable hours (1,000). Your break-even hourly rate is $126 per hour. If you charge $100 an hour because that is the "going rate," you are losing $26 on every hour you work, and you will inevitably find yourself pulling from personal savings or racking up credit card debt to survive.
Breaking even is not the goal of a business. Profit is not your salary; profit is the reward the business earns for existing and taking on risk. Profit allows you to buy a new truck in cash when the old one dies, hire an employee without panicking about the first month of payroll, or weather an unexpected economic downturn.
Healthy contracting businesses typically aim for a net profit margin between 10% and 20%. To calculate your target hourly rate with profit, you cannot simply add 20% to your break-even rate (that calculates markup, not margin). Instead, divide your break-even rate by the inverse of your target margin.
If your break-even rate is $126 and you want a 15% net profit margin, divide $126 by 0.85 (which is 1 - 0.15). Your target hourly rate becomes $148.23. You can round this up to $150 an hour for simplicity.
This is what you should charge per hour as a contractor in this scenario. At $150 an hour, every hour you bill pays your salary, covers your taxes, keeps the truck running, pays for your software, and leaves $24 in the bank as pure business equity.
Once you know your required hourly rate, you have to decide how to present it to the customer. While some contractors bill strictly for time and materials, many in service trades shift to flat-rate pricing.
Flat-rate pricing uses your calculated hourly rate internally to build standard prices for specific jobs. If you know a water heater replacement takes 4 hours on average, and your rate is $150 an hour, your flat labor charge for that job is $600. You present the customer with a single price that includes parts, labor, and profit.
The operational advantage of flat-rate pricing is that it rewards efficiency. If you optimize your truck inventory, buy better tools, and complete that water heater replacement in 3 hours, your effective hourly rate on that job jumps to $200. Conversely, if you bill hourly, getting faster at your job actually penalizes you by reducing your revenue. Knowing your exact hourly break-even cost is the necessary foundation for building a profitable flat-rate price book.
Contractors often fear that if they charge their mathematically required rate, they will lose bids. It is true that a $150 hourly rate will cost you the bottom tier of price-shopping customers. However, the operational reality is that you are better off losing those jobs.
Working for less than your break-even rate destroys your business from the inside out. You end up working 60-hour weeks just to cover the bills, leading to burnout. You cannot afford proper maintenance, which leads to equipment failure. You cannot afford to hire help, trapping you as an exhausted solo operator indefinitely.
When you charge the correct hourly rate based on your actual numbers, you gain the operational capacity to provide a premium service. You have the margin to show up on time, maintain a clean and reliable vehicle, stand behind your warranty work without financial stress, and actually answer the phone when customers call. Quality clients will pay for this reliability.
Figuring out what you should charge per hour as a contractor is not an exercise you do once and forget. As your overhead increases—whether through rent hikes, insurance premiums, or hiring an administrator—your break-even point shifts. You must review your burdened costs, overhead, and utilization rates at least twice a year.
Stop looking at competitors to dictate your financial future. Sit down with your numbers, identify your true costs, set realistic efficiency targets, and charge the rate that your business requires to thrive. The math does not lie, and ignoring it is the fastest route to failure in the contracting industry.
