What this calculator does
Enquiries that wait go cold: the customer messages a competitor, finds an answer elsewhere or simply moves on. This calculator estimates what replying faster could be worth each month, using your own numbers. The key input is your estimate of how many leads you lose for each hour a reply waits. We do not supply a figure for it, because it varies by trade and we will not invent one. Look at your own WhatsApp or inbox history to set it, or try a few values to see the range.
How it is calculated
Leads lost to delay = Enquiries × min(Reply hours × Loss per hour, 95%)
Close rate among leads still interested = Current close rate ÷ (1 − Share lost now)
Sales at target = Enquiries × (1 − Share lost at target) × that close rate
Extra revenue = (Sales at target − Sales now) × Average sale value
Worked example (hypothetical numbers)
60 enquiries a month, KES 25,000 average sale, 20% closed, replies after 6 hours and an estimated 5% loss per hour. That means 30% of leads are lost to delay now, against 2.5% at a 30-minute reply. On these assumptions, replying in 30 minutes adds about 4.7 sales, or roughly KES 118,000 a month. Change any input and the result updates instantly in your browser.
Frequently asked questions
Where does the loss-per-hour figure come from?
From you. It is an estimate you set from your own experience or records. The calculator does not use an industry statistic.
How can a small team reply faster?
Use instant WhatsApp or form auto-replies that confirm receipt and next steps, route enquiries to one shared inbox, and set a reply target for working hours. See our AI automations service.
