Capacity and Staffing Calculator

Check whether your home-service business has the capacity to meet the demand coming in and how many technicians you actually need so you stop turning work away or carrying idle crew. Adjust the jobs coming in per week, the average hours per job, the technicians on payroll, the billable hours per tech and the average job value, and you will see your utilization rate, your real capacity in jobs, your headroom or shortfall, the technicians needed and the revenue you leave on the table each week when demand outruns capacity. A transparent model, no promises.

Your demand and your crew

Demand: requests you receive and want to take on each week.

Average time on site, including travel.

3
30

Real hours on site, not hours worked. Rarely above 30-35.

What you invoice on average per closed job.

Directional model. Above 100% utilization you turn work away and burn out the crew; below 70% you carry idle capacity you already pay for. Assumes uniform billable hours per tech; real results depend on your job mix and seasonality.

How it works

Capacity is the question almost nobody in the home-service trades asks cold: does the work coming in fit into the hours my crew can actually deliver? Most owners run it by feel, and by feel you make the two expensive mistakes of the business. Either you take on more work than you can deliver, run late on customers and burn out the crew. Or you carry technicians below their capacity, paying wages that never turn into invoices.

This calculator puts numbers on that question. Adjust your figures above and you will see, in real time, your utilization, your capacity in jobs and how many technicians you need to cover the demand on your plate.


How to read the results

  • Crew utilization is the headline number: what percentage of your crew's capacity the current demand is taking up. Above 100% you are slammed; below 70% you have slack.
  • Capacity (jobs/week) is how many jobs your crew can do per week with the billable hours it actually has.
  • Headroom or shortfall turns that capacity into something tangible: how many jobs you have to spare, or fall short by, against the demand coming in.
  • Technicians needed is the crew size that would cover current demand without turning work away.
  • Revenue left on table/week is the money that walks out the door each week when demand outruns your capacity and you have to say no.

Real capacity, not capacity on paper

The most common planning mistake is counting the hours a technician is on the clock as if they were all billable. They are not. Between travel, materials runs, estimates and paperwork, a full-time tech rarely bills more than thirty hours a week. If you plan on forty, you overstate your capacity and commit to a volume you cannot deliver on time. That is why this tool reasons in billable hours: it is the only honest measure of what your crew can produce.

When to hire and when not to

When you are slammed, the temptation is to hire right now. First, look at the trend. Utilization above 100% for several weeks running, with revenue left on the table every week, is a solid signal to add a technician: you are turning away work you could bill. But if the overload is a seasonal spike, a full-time tech becomes a fixed cost once demand drops. The question is not just how much work I have today, but how much I will have steadily three months from now.

The cost of turning work away versus idle techs

Both sides of capacity cost money. Turning work away is direct lost revenue plus crew burnout. Carrying technicians below 70% is idle capacity you are already paying for. If you have slack, the problem is not the crew, it is the work coming in. Close the demand leaks you already generate first (answer every call, respond fast), then work on visibility and conversion to fill the schedule before you think about cutting.

What to do with the number

If you are short on capacity, size the hire with the technicians-needed figure and first make sure you are not losing the demand already coming in: the missed-call revenue calculator shows how much work falls through from not answering.

Talk to the team
  1. Q/01How does the tool calculate my capacity and utilization?

    First it works out your capacity in hours: it multiplies the technicians on payroll by the billable hours each one does per week. Then it works out your demand in hours: it multiplies the jobs coming in per week by the average hours you spend on each job. Utilization is demand divided by capacity, as a percentage. Above 100% means more work is coming in than your crew can do; below 70% means you have idle capacity. Capacity in jobs is your available hours divided by the average hours per job, and headroom or shortfall is that figure minus the jobs that actually come in.

  2. Q/02Why use billable hours instead of hours worked?

    Because a technician's real capacity is not the hours they are on the clock, it is the hours they actually spend on site getting paid. Between travel, picking up materials, writing estimates, paperwork and downtime, a tech who works forty hours a week rarely bills more than thirty. If you plan your crew on hours worked instead of billable hours, you overstate your capacity and end up taking on more work than you can deliver on time. That is why the billable-hours-per-tech field is the one that really drives the math.

  3. Q/03When should I hire another technician?

    The clear signal is sustained utilization above 100% combined with revenue left on the table every week: it means you are turning away work you could be billing. The technicians-needed field tells you how many it would take to cover current demand with your billable hours. Before you hire, confirm the high demand is stable and not a seasonal spike, because a full-time tech is a fixed cost: if demand drops later, you are left with idle capacity. The healthy rule is to hire once you have run several weeks over capacity and the trend holds.

  4. Q/04What costs more: turning work away or carrying idle techs?

    Both cost money, in opposite directions. Turning work away because you are over capacity is direct lost revenue: the customer goes to a competitor, and on top of that you burn out your crew with impossible schedules. Carrying technicians below 70% utilization is idle capacity you are already paying for in wages with nothing billed in return. The healthy band usually sits between 85% and 100%: you make full use of your crew without overloading it. The tool shows which side you are on so you can adjust staffing or demand accordingly.

  5. Q/05How do I get more demand if I have idle capacity?

    If your utilization is well below 100%, the problem is not the crew, it is the work coming in. The first step is to stop losing the demand you already generate: answer every call, respond fast and close estimates well. From there, work on visibility and conversion so more requests come in. Filling the schedule of an underused crew is almost always more profitable than cutting staff, because you are already paying the fixed cost.

  6. Q/06Are these numbers a staffing recommendation for my business?

    No. It is a directional model that starts from your own numbers to size the problem, not a guarantee or a finished hiring plan. It assumes uniform billable hours across technicians and ignores specializations, seasonality and one-off spikes. Its value is giving you a clear order of magnitude: whether you are over or short on capacity, how much revenue you leave on the table and how many technicians it would take, so you can decide sensibly whether to hire, subcontract or generate more demand.
