Speed to lead calculator
Estimate how much revenue slow lead response costs you each month. Speed to lead (also called speed to contact or lead response time) is the gap between a lead arriving and the first real attempt to reach them, and it is one of the highest-leverage numbers in sales.

What slow response costs you
The math is simple and fully visible: leads that miss a fast first touch close at your slow rate instead of your fast rate, and the difference is the money left on the table. It is an estimate, not a measurement; your real numbers depend on your market and your list.
The research behind the defaults
The landmark 2007 Lead Response Management study (Dr. James Oldroyd, with InsideSales.com) found the odds of making contact with a lead were about 100 times higher when calling within 5 minutes versus 30 minutes.
The same study found the odds of qualifying a lead were 21 times higher at 5 minutes versus 30. Note what it measured: odds of qualifying, not closed revenue. Most marketing pages misquote this one.
That anchor study is nearly two decades old, and almost every vendor still leans on it. The honest takeaway holds up: intent is perishable, reachability collapses fast, and the first company to have a real conversation usually frames the decision.

This calculator guesses. A seed lead measures.
Every number above depends on one input nobody actually knows: the share of leads that really get a fast first touch. CRM timestamps are self-reported, and reps log "contacted" at the moment convenient for them. DummyLead plants a decoy seed lead in your own flow and timestamps the real gap between arrival and the first call, text, or email, so you can run this math on your true speed to contact.
