Lost Revenue Calculator
Use this estimator to quantify how much revenue can leak from missed leads, low contact rates, and inconsistent follow-up. It is built for local and service businesses that rely on lead flow to scale.
Calculate your current leakage
Formula: lost leads from missed + uncontacted inquiries, multiplied by close rate and average job value.

How to interpret the numbers
The model assumes lost opportunities come from two places: leads you miss immediately and leads you do not contact fast enough. Then it applies your close rate and average deal value to quantify the monthly and annual revenue impact. The sections below walk through the exact formula, a worked example, and what to do next.
The formula, written out
The calculator estimates lost revenue from two leakage streams, then applies your close rate and average job value.
Missed leads = Monthly leads × (Missed lead rate ÷ 100).
Uncontacted leads = (Monthly leads − Missed leads) × (1 − Contact rate ÷ 100). These are inquiries you received but did not successfully reach.
Lost leads = Missed leads + Uncontacted leads.
Lost customers = Lost leads × (Close rate ÷ 100). This assumes the lost inquiries would have closed at the same rate as the leads you do handle.
Lost revenue / month = Lost customers × Average job value. Annualize by multiplying by 12.
Each variable should come from your own operations: lead volume from ads, forms, and calls; missed and contact rates from call tracking or CRM disposition; close rate from sold jobs ÷ qualified leads; average job value from closed revenue ÷ closed jobs.
A worked example for a service business
Imagine a residential HVAC company generating about 220 leads per month from Google Ads, Google Business Profile, and the website. Average booked job value is $2,400. Their ops data shows roughly 18% of leads never get a real attempt (after-hours forms, abandoned chats, unreturned voicemails). Of the remaining leads, they successfully contact about 62% — the rest stall in the queue or go cold. Their lead-to-sale close rate on contacted opportunities is about 28%.
Missed leads ≈ 220 × 0.18 = 40. Uncontacted leads ≈ (220 − 40) × (1 − 0.62) ≈ 68. Lost leads ≈ 108. Lost customers ≈ 108 × 0.28 ≈ 30. Monthly lost revenue ≈ 30 × $2,400 ≈ $72,000 — on the order of $860,000+ per year if those rates hold.
Those defaults are illustrative, not a claim about your market. Swap in your CRM numbers and the model updates immediately. The point of the example is to show how modest leakage rates compound when job values are high.
How to think about missed-lead and contact rates
Missed-lead rate answers: of all inquiries, what share never entered a real sales conversation? Contact rate answers: of the leads you did try to work, what share did you actually reach? Keeping them separate matters — fixing nights-and-weekends coverage lowers missed leads, while speed-to-lead and multi-touch dialing raise contact rate.
Published “industry averages” for these metrics are often marketing claims without comparable definitions, so this page does not invent statistics. Qualitatively, teams that only answer during business hours, lack call recording, or route every lead to a shared inbox tend to see higher leakage. Teams with after-hours coverage, SLA timers, and CRM-enforced follow-up tend to see less. Measure your own baseline for two to four weeks before trusting any forecast.
If you cannot measure yet, start conservative: enter a missed-lead rate and contact rate that feel honest for your worst recent month, not your best week. Over-optimism hides the cost of the problem.
What to do about each input
To lower missed leads: cover nights and weekends (even with a vetted answering service), keep forms and click-to-call working on mobile, and alert a human when high-intent actions fire. Dead phone trees and “we’ll get back to you” pages are common silent killers.
To improve contact rate: tighten speed-to-lead (minutes, not hours), use a short multi-attempt cadence across call and SMS, and assign ownership so leads do not sit in a shared queue. Track first-touch time in the CRM so the rate is visible weekly.
To raise close rate: qualify earlier (job type, timeline, service area), send estimates faster, and align ad messaging with what sales can actually fulfill. Better lead quality often moves close rate more than a new script alone.
To protect average job value: avoid training the market to chase the cheapest quote. Use landing pages and intake questions that attract the jobs you want — then feed those outcomes back into your ads and follow-up.
If the monthly leakage number is material, pair this estimate with a free performance audit or run the PPC calculator to see whether spend, conversion, or operations is the tighter constraint.
Prefer a guided diagnosis instead? Request a free performance audit — or run the PPC calculator if you want spend-side projections next.
Yes. The tool is free to use in your browser — no account, no download, and no obligation to book a call. It is built for service business owners who want a clear estimate of what missed and weakly handled leads may be costing them.
The model is only as good as the inputs you provide. If your missed-lead rate, contact rate, close rate, and average job value are close to reality, the output is a useful planning number — not a guarantee. Treat it as a diagnostic starting point, then validate against your CRM and call logs.
A missed lead is an inquiry you never meaningfully engage — for example an after-hours form with no callback, a call that goes to voicemail and is never returned, or a chat that expires without a human response. It is different from a lead you contact but fail to close.
Contact rates vary widely by channel and staffing. Many local service teams struggle when leads arrive nights and weekends, or when routing is manual. Rather than inventing a benchmark, use your own CRM: count leads contacted within one business day divided by total leads. That measured rate is what you should enter.
No. The calculator quantifies leakage from the numbers you already know. A performance audit reviews ad accounts, landing pages, and conversion paths to find why leads miss, stall, or close poorly — then prioritizes fixes. Use the calculator to size the problem; use an audit to diagnose it.
The PPC calculator projects outcomes from ad spend (clicks, leads, CPL, ROAS). This tool estimates revenue you may already be losing from lead handling — missed inquiries, slow contact, and close-rate gaps — regardless of channel. Use both when you want spend forecasts and leakage cost in one planning pass.
Turn lost demand into booked revenue
If this gap is material, your growth bottleneck is usually a mix of lead response operations, landing page quality, and follow-up system design. FuelLabs can help you fix that end-to-end.
