Speed-to-lead calculator

How fast you answer a new lead changes how many become customers. This calculator estimates the revenue at stake if your first reply moved inside an hour, with the research and every assumption shown.

An estimate, not a promise. The lift is your assumption: the 2011 Harvard Business Review study of 2,241 firms found leads contacted within an hour were nearly 7× as likely to be qualified as those contacted an hour later, and over 60× as likely as after 24 hours. That measured qualification, not closed deals, so the defaults here are far lower. Close rate is capped at 95%.

How to use it

  1. Enter your monthly leads, your close rate today and your average deal value.
  2. Choose how long your first reply usually takes; adjust the assumed lift if you have your own data.
  3. Read the deals and revenue at risk each month and each year.

Questions

Does responding to leads faster really increase sales?

The most cited study, published in Harvard Business Review in 2011, audited 2,241 US firms and found that those who tried to contact a lead within an hour were nearly seven times as likely to qualify it as firms that waited an hour longer. It measured qualification rather than closed deals, and it is from 2011.

Why are the default lifts so much lower than the research?

Qualifying a lead is not the same as closing it, and markets have changed since 2011. The defaults (1.5× for replies within a day, 2.5× for slower ones) are deliberately conservative; replace them with the lift you see in your own data.

What counts as the first reply?

The first real human or useful automated response to the lead, not an auto-acknowledgement. An instant reply that answers the question and offers a time to talk counts; a generic “we received your message” does not.

How do I get my response time under an hour?

Route every form, missed call and message to one inbox, send an immediate useful reply automatically, qualify with a few questions, and offer a booking link, with a person confirming before a meeting is promised.
