The math

Lead response time ROI calculator

This response rate calculator estimates how response time changes how many leads you reach — not just how fast you call. Put your real numbers in; the comparison shows what one-minute automation earns versus waiting an hour. For why the first five minutes matter, see our speed-to-lead guide.

That's $18,000 a year — the gap between your current response time and answering in under one minute.

Formula: leads × contact rate × close rate × job value. Contact rate follows the decay curve from lead-response research (MIT/InsideSales, HBR) — steepest in the first hour. Your close rate applies only to leads you actually reach.

Close the gap — two ways

The calculator sizes the leak. Fixing it is a four-step automation: instant SMS + email on every form submit, a booking link when they reply, a human task if nobody answers in an hour, and stop conditions so it never feels robotic. The full workflow lives on our speed-to-lead automation page.

Common questions

Lead response time, answered

How do I calculate lead response time?
Subtract the timestamp when the lead arrived (form submit, ad click, inbox message) from the timestamp of your first reply — call, SMS, or email. Average that across a month for your team median. Under one minute automated and under one hour human is the target most local businesses aim for.
What is a good lead response rate?
Aim to reach at least 80–90% of new leads within five minutes. Instant automated SMS and email on form submit typically contacts 85–95% of inquiries; human-only teams often land at 40–60% when average response stretches past an hour. Response rate is the share of leads you actually reach — and it drops sharply after thirty minutes, which is why speed-to-lead automation matters more than perfect scripts.
What is a good lead response time for a small business?
Under five minutes for human response, under one minute if automation handles the first touch. Research consistently shows contact rates collapse after thirty minutes and especially overnight. The five-minute window is where most comparison shoppers pick whoever answered first.
How does response time affect close rate?
Response time mostly changes how many leads you reach at all — not your skill on the phone. A 20% close rate on reached leads becomes far fewer won jobs when slow follow-up means you only speak with half your inquiries. Speed buys conversations; your close rate converts them.
Is this lead response time calculator accurate?
It uses a contact-rate curve shaped like published MIT and Harvard lead-response studies, tuned for local service businesses — not enterprise SaaS averages. Your real numbers depend on lead source, industry, and how hot the inquiry was. Use it to size the problem, then validate with a week of timestamped CRM data.
How do I fix slow lead response?
Instant SMS and email on every new form submission, a booking link as the second message, and a human task if nobody replies within an hour. That four-step recipe runs on GoHighLevel's $97/month plan — see our speed-to-lead guide for the walkthrough or our solution page for the full case.
