You carry tools in your truck. Here are the tools for your office.

Running a field service business involves complex math. You have to calculate overhead, burden rates, marketing acquisition costs (CAC), and software ROI.

Most contractors do this math on a napkin—or worse, they guess.

“Gut feeling” pricing is why 20% of contractors fail within the first year.

We built this suite of free tools to help you move from “guessing” to “data-driven decisions.”

  • No Email Required: We don’t hide these tools behind a lead form.

🧮 Financial & Pricing Tools

1. Hourly Labor Rate Calculator

Are you charging enough to be profitable?

Most contractors set their price by copying their competitors. This is a mistake. This tool adds up your overhead (insurance, truck payments, software) and desired profit margin to tell you exactly what you must charge per hour to stay in business.

  • Best For: New businesses & Solo Operators.
  • What it does: Calculates your “Burdened Labor Rate” and “Break-Even Price.”
  • 👉 Launch Rate Calculator

2. Field Service Software ROI Calculator

Is that $300/month software worth it?

Sticker shock is real. This tool does the math for you. It calculates how many “saved admin hours” or “upsold jobs” you need to break even on a software investment like ServiceTitan or Jobber. It proves whether the software is an expense or an investment.

  • Best For: Owners deciding on a software budget.
  • What it does: Shows your estimated Annual Profit Increase.
  • 👉 Launch ROI Calculator

📈 Growth & Marketing Tools

3. Marketing Budget Estimator

How much should you spend on Google Ads?

The “5% Rule” is a myth. This tool helps you calculate your marketing budget based on your revenue goals and your average Cost Per Lead (CPL) in the HVAC/Plumbing industry.

  • Best For: Companies looking to scale from $500k to $1M+.
  • What it does: Calculates required monthly ad spend to hit your job targets.
  • 👉 Launch Budget Calculator

4. Truck Revenue Forecaster

Can you afford to hire another technician?

Adding a truck creates a liability until it hits a specific revenue milestone. Use this tool to input your average ticket size and calls-per-day to forecast the profitability of a new van.

🧠 Why You Need to Know Your Numbers

We talk to hundreds of business owners. The ones who struggle are the ones who treat their finances like a mystery. The ones who succeed treat their finances like a science.

The “Overhead Blindness”

You might charge $100/hour and think you are making money. But if you haven’t calculated your “Burden Rate” (the cost of unbillable time, fuel, vehicle wear, and software subscriptions), your actual cost might be $85/hour. That leaves you with $15 profit—not enough to survive a slow winter.

The “Fear of Investment”

We often hear: “I can’t afford $300 a month for Housecall Pro.”
But if that software helps you sell one extra $600 repair per month, it is free. Our ROI Calculator proves this mathematically. When you see the numbers, the fear disappears.

Ready to Automate the Math?

Calculators are great for planning, but you shouldn’t be doing manual math every day. The right software handles your pricebook, profit margins, and commissions automatically.
