Each channel's monthly revenue is calculated as lead count times close rate times average sale value, with the two channels compared directly. The formula assumes a flat average sale value across both channels and a close rate that does not vary by lead volume, neither of which is guaranteed in practice. It uses the numbers you enter, it does not pull in Lead Recorder's own dataset or any external benchmark.
Lead Recorder attaches the actual channel, ad, or keyword to every form fill and call, so this number becomes a fact, not a guess.
Try Lead Recorder freePhone leads and form leads rarely close at the same rate, and most call tracking stops at 'someone called,' not which channel drove that call or how fast anyone picked up. Lead Recorder tags every phone click and form fill with the channel that drove it, so you can see which source deserves a faster response, not just a bigger ad budget. Contacting a lead within 5 minutes instead of 30 makes you 100x more likely to reach them and 21x more likely to qualify them (InsideSales.com / MIT Sloan, Dr James Oldroyd, 2007), and the average company still takes 42 hours to respond at all (Harvard Business Review, Oldroyd, McElheran & Elkington, 2011).
Run the calculator with its defaults and you get a phone-lead revenue of $7,000 against a form-lead revenue of $4,000, a gap of $3,000 a month, even though both channels are set to send 40 leads. The only thing driving that gap is the close rate you enter for each channel, 35% for phone versus 20% for form in the default example. That's the whole point of building the calculator this way: lead count tells you volume, close rate tells you what the volume is worth, and most owners only ever look at the first one.
The gap number matters more than either revenue figure on its own, because it's the number that tells you where a faster follow-up process would actually pay off. If your phone leads close at nearly double the rate of your form leads, a slow response on phone leads is costing you more per hour of delay than a slow response on form leads, even if your team treats both the same way today.
None of this requires you to guess. Pull your own close rates from whatever CRM or call log you already have, plug them in alongside your real lead counts and average sale value, and the calculator recalculates the gap for your business rather than the illustrative one above.
The research on response speed is blunt about what's at stake once a lead exists. Contacting a lead within 5 minutes instead of 30 makes a business 100x more likely to reach that person and 21x more likely to qualify them (InsideSales.com / MIT Sloan, Dr James Oldroyd, 2007). That's not a small optimization, it's close to the difference between a lead that converts and one that never gets a real conversation. And most companies aren't close to a 5-minute standard: the average response time sits at 42 hours (Harvard Business Review, Oldroyd, McElheran & Elkington, 2011), and a separate, larger audit of 14,000 companies found the average had actually slipped to 61 hours, with 47% of leads never getting a response at all (InsideSales.com / XANT, 2014).
A close-rate gap between phone and form leads is very often a response-speed gap wearing a different name. A phone lead who calls is asking to talk right now, and if someone picks up, the conversation happens immediately. A form lead sits in an inbox until someone checks it, and by the time that happens the person may have already called a competitor. If your form close rate is lower than your phone close rate, it's worth checking whether that's a real difference in lead quality or just a difference in how long each one waits for a reply.
One claim you'll see repeated in sales blogs is that 78% of customers buy from whichever company responds first. That figure is untraceable to any real study, and it's frequently misattributed to the 2007 Oldroyd/MIT Sloan research, which measured contact and qualification odds only and never produced a close-rate percentage like that. The 100x and 21x figures above are the real findings from that study. Use those, not the 78% figure, if you're citing this to a team or a client.
The calculator assumes one average sale value across both channels and a close rate that holds steady regardless of how many leads come in each month. Neither assumption is guaranteed to match reality. A locksmith call and a locksmith form fill might close at genuinely different job values, and a close rate that looks fine at 40 leads a month can slip once volume doubles and follow-up gets stretched thinner. Treat the output as a directional comparison, not a forecast.
It also only works with the numbers you type in. Lead Recorder can tell you which channel a phone click or form fill came from, but the close rate and average sale value fields here are yours to supply, the calculator doesn't pull from Lead Recorder's dataset or from any outside benchmark to fill them in for you. If you don't already track close rate by lead type, that's the first gap to close before this tool tells you anything useful.
It's also worth knowing what Lead Recorder itself does and doesn't capture, since the two are easy to conflate. It tags phone clicks with the channel that drove them, it does not record or transcribe the calls themselves, and it has no session-replay or heatmap feature. What it gives you is the attribution layer this calculator depends on, the actual close-rate and revenue math still lives with your sales process and your own accounting.
No hidden formula: here's exactly what this calculator assumes and why.
They are just starting points, 35% for phone leads and 20% for form leads, not a measured industry average. Replace them with your own numbers from your CRM or booking system. If you do not track close rate by source yet, that gap is itself worth fixing before you trust any calculator's output.
No. It only compares revenue at whatever close rates you enter. It does not track your actual response times or call recordings, Lead Recorder detects that a call click happened and where it came from, it does not record or transcribe the call itself.
One common explanation is urgency: someone tapping a phone number mid-search is often closer to a decision than someone filling in a form to be contacted later. We are not claiming that pattern holds for your business, only that it is worth testing with your own numbers rather than assuming both channels behave the same.
No. That figure circulates widely but is untraceable to any real study, including the one it is often pinned on (InsideSales.com/MIT Sloan, 2007), which measured contact and qualification odds only, not close rates. This calculator does not use that number anywhere. It uses close rates you supply.
It does not tell you why your close rates differ, whether faster follow-up would actually change them, or what is happening on channels beyond phone and form, like email or bookings. It is a way to see the size of a gap you already suspect exists, not a diagnosis of its cause.
Lead Recorder captures the actual source behind every form fill and call, so you're reporting what happened, not what a calculator assumes.
