Lead Response ROI Calculator

What slow answering costs you a year

Enter five numbers you already know and this works out what your current response time costs per year. Every figure is yours — nothing here multiplies your inputs by an industry statistic, because your close rate is the only one that matters.

What this assumes

Three things, stated so you can argue with them.

  • The gap between your fast and slow close rates is causal. Partly it is not — some slow-answered enquiries were never going to close. Treat the output as an upper bound on the opportunity, not a promise.
  • Nothing else changes. Answering faster does not fix a weak offer or a bad price. It removes one specific loss.
  • Margin, not markup. If you entered a markup figure the result is overstated — see markup vs margin, which is a more common mix-up than it sounds.

The number most people get wrong is the second input. Almost nobody knows what share of their enquiries actually go unanswered, because a missed enquiry produces no record. The free diagnostic measures it directly rather than asking you to guess.

Frequently asked

How do I calculate what slow lead response costs?

Multiply annual enquiries by the share that get a slow answer, then by the difference between your fast close rate and your slow close rate. That gives jobs lost. Multiply by average job value and your gross margin for the profit at stake.

What counts as a slow answer?

Any enquiry not reached while the person is still deciding — in practice, anything beyond about five minutes, plus everything that arrives after hours and is not handled until morning, plus calls that were never answered.

Is this calculator accurate?

It is arithmetic on your own inputs, so it is exactly as accurate as they are. It assumes the gap between your fast and slow close rates is entirely causal, which overstates slightly — treat the result as an upper bound.
