What is speed to lead and why does it decide revenue?

Speed to lead is the elapsed time between a prospect raising their hand and a human or agent actually reaching them. It matters because contact rate decays on a curve, not a straight line, and the curve is steepest in the first few minutes. A lead you call inside a minute connects far more often than the same lead called an hour later, and the one called the next morning is frequently gone to whoever answered first. Nothing else about the lead changed. Same intent, same budget, same fit. The only variable is how long they waited. That makes response time the cheapest revenue lever most operators own, because it costs nothing per lead and it applies to every lead already in the pipeline.

How does this calculator work?

You enter five things: inbound leads per month, your current response time in minutes, your close rate on the leads you do reach, average deal value, and the response time you are comparing against. From those it models a contact-rate decay curve, then computes deals and revenue at your current speed, deals and revenue at sub-minute response, and the gap between them, which is the revenue sitting on the table right now. It also shows the contact rate at each speed, revenue lost per month and per year, and what an always-on agent costs against what it recovers, so you get a payback in months rather than a vague promise. Nothing is stored and your inputs are encoded in the URL so you can share the exact scenario.

Where does the contact-rate decay curve come from?

It is a modeled curve, not a claim about your specific market, and the calculator is transparent about that. The shape follows the pattern repeatedly observed in inbound lead response research: contact rate is highest in the first minute, falls sharply through the first hour, and flattens into a long low tail after roughly a day. The model uses a decay function fitted to that shape rather than a lookup table, which means the relative comparison between two response times is the useful output, not the absolute percentage. If you know your real contact rate at your current speed, treat the tool as a ratio: the multiple between the two scenarios is far more robust than either number on its own.

Is faster response really worth more than better sales training?

For most agencies with an inbound flow, yes, and the arithmetic is why. Sales training lifts your close rate on conversations you are already having. Response time lifts the number of conversations you get to have at all. If you contact 30 percent of leads and close 25 percent of those, doubling your contact rate is worth more than a five-point close-rate improvement, because it multiplies the top of the funnel rather than nudging the bottom. The two compound, so the honest answer is do both. But if you are choosing what to fix first and your response time is measured in hours, speed is the larger and faster number, and it does not require anyone to change how they sell.

Do I need a voice agent, or can I just answer faster?

If you can genuinely answer every inbound lead within a minute, every hour you are open, you do not need an agent for this problem. The reason most operators cannot is structural rather than a discipline failure: leads arrive at 9pm, on Saturday, while you are on another call, and during the exact hours you are delivering client work. A human team that covers that window costs salary and still sleeps. An agent answers the 9pm lead, qualifies it, books the meeting, and hands you a transcript. The realistic comparison is not agent versus a perfect human, it is agent versus the leads that currently go to voicemail and never call back.

How much does an always-on voice agent actually cost?

Less than most operators assume, because the cost scales with minutes rather than headcount. On Hermes, plans start at $149 per month with 300 included minutes, $399 for 1,000 minutes, and $699 for 2,000 minutes, with a published $0.24 per minute overage after that. A two-minute qualifying callback means 300 minutes covers roughly 150 leads a month. The calculator puts your recovered revenue against that spend directly so you can see payback rather than take it on faith. Hermes runs white-label, so if you are deploying this for clients they see only your brand, you keep the margin, and the first agent is typically live in 72 hours.

/ speed is a coverage problem, not a discipline problem

Nobody misses the 9pm lead on purpose. They miss it because they are asleep, on another call, or delivering client work. An agent picks up on the first ring, qualifies against your criteria, books the meeting, and hands you the transcript. Hermes runs it under your brand with CRM and campaigns included, first agent live in 72 hours, from $149 per month with 300 included minutes, $399 for 1,000, $699 for 2,000, and $0.24 per minute after that.

how it works

The lead did not go cold. You did.

Every inbound lead has a window, and it is shorter than anyone plans for. The prospect filled in a form or called because a problem was in front of them at that moment. Ten minutes later they are back in a meeting. An hour later they have filled in two more forms. Tomorrow morning the person who answered first is already scheduled. Nothing about the lead degraded, and the budget did not disappear. The only thing that changed is who reached them first, which means response time is not a service metric. It is a revenue metric wearing a service metric costume.

The reason this stays invisible is that the loss never appears on a report. A lead you never connected with is not a lost deal in your pipeline, it is a row that quietly stayed at new and got archived at the end of the quarter. There is no line item called revenue we did not get because we called at 4pm. So operators optimize the part they can see, the close rate, and grind for five points on conversations they are already having, while the larger number sits one layer above in the conversations they never had at all.

The arithmetic favors the top of the funnel. If you reach 30 percent of leads and close a quarter of those, your end-to-end conversion is 7.5 percent. Lifting the close rate to 30 percent takes you to 9 percent, a real improvement that requires changing how your team sells. Lifting contact rate from 30 to 60 percent takes you to 15 percent and requires only that someone picks up sooner. Same leads, same pitch, roughly double the deals. That is why speed is usually the first fix rather than the last, and why it is worth measuring before spending anything on more traffic.

Answering in under a minute at 9pm on a Saturday is not a discipline problem, it is a coverage problem, and hiring for it is expensive. A voice agent picks up on the first ring, qualifies against your criteria, books straight into your calendar, and hands you a transcript before you have finished what you were doing. Hermes runs that under your own brand with the CRM and campaign layer included, first agent live in 72 hours, from $149 per month with 300 included minutes, $399 for 1,000, $699 for 2,000, and a published $0.24 per minute after that. Run the calculator at your real response time first, then at one minute, and compare the two revenue lines.
