Lead Response Calculator
Speed to first reply is the cheapest lever most trades never pull. Put in your own fast vs slow close rates and see what the gap is worth.
Estimate only. Your two close rates are the whole model — measure them from your own job sheet for a month before relying on this.
Benchmarks to sanity-check against
Published B2B and home-services studies consistently show contact and qualification rates falling sharply when first response slips from minutes to an hour, and again by the next day. The exact multipliers vary by study and sector; that's why this calculator asks for your own two rates rather than asserting one.
How Callkept changes the fast rate
Missed and after-hours enquiries get a first reply in seconds, are qualified, and are booked from real availability — so the "fast" bucket becomes most of your enquiries, not the few you happened to catch.
