Form CMB-002 Rate calculation
Contractor Hourly Rate Calculator
Knowing your real hourly rate is the single most important number in your contracting business. Most contractors pick a number that sounds right, or match what a competitor charges, without accounting for the full picture: salary goals, overhead that adds up faster than expected, profit margins that actually sustain a business, and the surprisingly small number of hours you can genuinely bill each year. This calculator walks you through each variable systematically. Select your trade for instant defaults based on industry data, or enter custom figures for your specific situation. The result is the minimum hourly rate you need to charge to cover all costs, pay yourself what you deserve, and still put profit back into the business. If the number surprises you, that is exactly the point. Better to know now than after a year of undercharging.
✓ How It Works
The hourly rate calculator starts with your target annual salary, which is what you want to take home before personal taxes. It then adds your total annual overhead: truck payments, insurance, tools, shop rent, phone, software, marketing, licensing, and any other fixed cost of running your business. These two numbers combined represent your minimum annual revenue at breakeven.
Next, the calculator applies your profit margin target. If you want a 15% profit margin, it scales the revenue up so that after paying yourself and covering overhead, 15% of every dollar billed is actual business profit. Finally, it divides that total revenue by your realistic billable hours: working days minus vacation, sick days, training, weather days, and drive time, multiplied by productive hours per day. The result is your minimum hourly rate. Charging less means you are subsidizing your clients with unpaid labor.
✓ When to Use This
Use this calculator when you are setting rates for a new contracting business and need a data-driven starting point. Use it when you suspect you have been undercharging and want to see the math in black and white. Use it before entering a bid where the client expects hourly billing rather than a flat quote. And use it every January when your overhead changes: insurance premiums go up, fuel prices shift, or you add a new truck payment. Recalculating annually keeps your rate aligned with your real costs and prevents the slow margin erosion that puts many contractors out of business.
✓ Frequently Asked Questions
How many billable hours should a contractor plan per year?
Most contractors can realistically bill between 1,100 and 1,400 hours per year. That accounts for weekends, holidays, vacation, sick days, training, administrative work, sales and estimating time, weather delays, and drive time between jobs. The common mistake is assuming 2,080 hours (40 hours times 52 weeks), which ignores all non-billable activities. A solo plumber running a service-call business might bill 1,200 hours. A painter with a crew might bill 1,400. Track your actual hours for a month and extrapolate.
What overhead costs should I include in my hourly rate?
Include every cost you pay regardless of whether you work a job that day: vehicle expenses (payment, insurance, fuel, maintenance), general liability and umbrella insurance, tools and equipment depreciation, shop or office rent, phone and internet, bookkeeping software and subscriptions, marketing and advertising, professional licenses and permits, continuing education and certifications, uniforms and safety gear. If you pay for it to stay in business, it belongs in your overhead calculation.
Should I charge different rates for different types of work?
Many successful contractors do charge different rates depending on the work. Emergency or after-hours calls typically carry a 1.5x to 2x premium. Highly specialized work that requires rare certifications can command higher rates. Simple maintenance tasks in competitive markets may need more aggressive pricing. The key is knowing your minimum rate so you never go below breakeven, even on discounted work. Some contractors maintain a base rate and adjust by job complexity, travel distance, or client type.
How do I account for vacation and sick days in my rate?
Your hourly rate needs to cover your income for the entire year, including the days you do not work. If you plan to take 10 vacation days and estimate 5 sick days and 10 weather days, those 25 days come out of your working days count. The calculator handles this: your annual revenue target stays the same, but it gets divided by fewer billable hours, which pushes your hourly rate up. Skipping this step is one of the most common reasons contractors feel underpaid despite staying busy.
What is the difference between my employee cost and my billed rate?
If you pay an employee $25 per hour, the true cost to your business is significantly higher once you add FICA taxes (7.65%), workers comp insurance (3-12% depending on trade), health insurance, retirement matching, paid time off, and other benefits. This loaded cost, or labor burden, can push the real cost from $25 to $35-45 per hour. Your billed rate for that employee needs to cover the burdened cost plus overhead allocation plus profit margin.
