Speed-to-Lead Lost Revenue Calculator

The contractor who calls back first usually wins. Enter your numbers below to see how much revenue slow follow-up is costing you every month and every year.

Your estimated lost revenue from slow follow-up

20 Leads handled slowly per month
5 Jobs lost per month to slow follow-up
$40,000 Revenue lost per month
$480,000 Revenue lost per year from slow follow-up
How this is calculated: Leads handled slowly = Leads per month x (Slow % / 100). Jobs lost = Slow leads x ((Fast close rate - Slow close rate) / 100). Revenue lost per month = Jobs lost x Average job value. Revenue lost per year = Monthly loss x 12.

Important: The default close rates shown are estimates based on typical ranges seen across residential contractors. Actual results vary based on trade, market, offer strength, how fast you follow up, and how you handle the conversation. These numbers are estimates only, not a guarantee, and are not drawn from Quantum Qube client data. Research consistently shows that speed of follow-up is one of the highest-leverage variables in contractor lead conversion. Fixing this one thing can recover a significant share of the revenue shown here.

Why speed to lead matters for contractors

The contractor who calls first usually wins.

A homeowner filling out a quote form is often submitting to two or three contractors at once. The first person to call back has a huge advantage. By the time the second contractor reaches out, the homeowner has often already committed mentally, even if they have not signed anything yet.

Most contractor businesses lose jobs not because their price is wrong or their work is bad, but because they let too much time pass. Even a 30-minute delay can cut your close rate significantly. A same-day system, whether you handle it manually or automate the first touch, is one of the highest-ROI changes a contractor can make.

Common questions

Speed-to-lead calculator FAQ

What is speed to lead and why does it matter for contractors?

Speed to lead is how quickly you contact a new inbound lead after they submit a form or call. Homeowners often submit quote requests to two or three contractors at the same time. The first contractor to call back has a significant advantage because the homeowner is still in decision mode and has not mentally committed to anyone yet. A same-day or faster response gives you a material edge over competitors who call the next day or later.

How much does slow follow-up actually cost a contractor?

It depends on your monthly lead volume, what share of leads get slow responses, and the gap between your fast and slow close rates. As a rough example, if you receive 30 leads per month and 40 percent get contacted slowly, and your fast close rate is 35 percent versus your slow close rate of 15 percent, you are losing several jobs per month. This calculator shows the dollar value of that gap using your specific numbers and average job value.

What counts as a fast versus slow response for contractor leads?

As an industry estimate, responding within the same hour is considered fast. Responding the same day is acceptable. Anything beyond that risks losing the job to a faster competitor. The defaults in this calculator use a fast close rate of 35 percent and a slow close rate of 15 percent as estimates to illustrate the gap. Your actual close rates at each speed will depend on your trade, market, and how well you handle the conversation.

How does this speed-to-lead calculator work?

Enter your monthly leads, the percentage of those leads that get contacted slowly, your close rate on fast contacts, your close rate on slow contacts, and your average job value. The calculator computes how many leads are handled slowly, how many jobs are lost due to the slower close rate, and the revenue lost per month and per year from that gap.
