Lead follow-up ROI calculator
Slow or missed follow-up quietly costs revenue. This calculator estimates it: multiply your monthly leads by the share lost to slow follow-up, then by your close rate and average deal size. The result is the revenue you could recover by capturing and following up on every lead on time.
Your numbers
Estimates only. Assumes lost leads would have closed at your normal close rate if followed up on time. Adjust the inputs to match your funnel.
How to calculate your lead follow-up ROI
- 1Enter your monthly leadsCount every inbound lead your team gets in a typical month — event taps, form fills, referrals, inbound.
- 2Add your average deal size and close rateUse the average revenue per closed deal and the share of properly-worked leads that become customers.
- 3Estimate leads lost to slow follow-upBe honest about how many leads never get a timely first touch. For most teams it is 20–40%.
- 4Read your recoverable revenueThe calculator multiplies lost leads by your close rate and deal size to show the revenue on the table.
Frequently asked questions
How do you calculate the ROI of faster lead follow-up?
Estimate the leads you lose to slow or missing follow-up each month, then multiply by your close rate and your average deal size to get the revenue those leads would have generated. Annualize it by multiplying by twelve. That figure is what faster, more consistent follow-up could recover — the return on fixing your follow-up process, before you spend a dollar on more leads.
What percentage of leads are lost to slow follow-up?
It varies, but for teams that capture leads in person or by hand it is commonly 20–40%. Leads decay fast: response rates drop sharply after the first 24–48 hours, and many never get a first touch at all because the contact sat in someone’s phone or a stack of business cards. The calculator lets you set your own percentage to match your funnel.
Why is fixing follow-up cheaper than buying more leads?
Because you already paid to generate the leads you are losing. Recovering a portion of them costs nothing extra in acquisition — it is a process fix, not a spend increase. Buying more leads on top of a leaky follow-up process just widens the leak. Most teams get a faster return by closing the follow-up gap first.
How does Bl1nk help recover these leads?
Bl1nk captures every lead the moment you meet — NFC tap, QR scan, or a form on your digital profile — straight into a shared dashboard and your CRM, so nothing sits in a personal phone. AI then scores each lead, flags who is ready, and drafts the follow-up, so timely follow-up happens by default instead of by memory.
