Missed-Call Revenue Calculator
Missed calls only cost you money if they would have become jobs. This calculator multiplies your missed calls by your close rate and average job value, shows every assumption, and returns a conservative monthly estimate. It runs in your browser and the result is visible without a signup.
Estimate what unanswered calls could be worth
Change any number and the estimate updates. Every default is labelled as an assumption or linked to a source, and you can replace all of them with your own figures.
Sanity-check your inputs against published benchmarks
These figures describe other businesses, not yours — use them to check whether your inputs are plausible, then trust your own logs first. Invoca's 2026 platform report puts unanswered calls at about 26% across industries. A 2024 411 Locals call-monitoring study of 85 businesses found only 37.8% of calls answered live, and Invoca's data suggests fewer than 3% of callers pushed to voicemail leave a message. Sources are linked at the bottom of this page.
A worked example, step by step
Dummy data, matching the page defaults. Every row is an editable assumption, and the arithmetic is exactly what the calculator runs.
| Step | Input | Value | Label and arithmetic |
|---|---|---|---|
| 1 | Missed calls per week | 10 | Assumption (illustrative dummy data) |
| 2 | Weeks per month | 4.33 | Assumption: 52 ÷ 12 |
| 3 | Missed calls per month | 43.3 | 10 × 4.33 |
| 4 | Share of missed calls that become jobs | 13% | Assumption, from the published method (70% × 60% × 30% ≈ 12.6%) |
| 5 | Missed jobs per month | 5.63 | 43.3 × 13% |
| 6 | Average job value | $800 | Assumption (illustrative) |
| 7 | Monthly revenue at stake | $4,503 | 5.63 × $800, rounded |
| 8 | Conservative monthly estimate | $3,377 | Row 7 × (1 − 25%), rounded |
| 9 | Conservative annual estimate | $40,529 | Row 8 × 12, rounded |
If the conservative figure is small, that is useful too: it says missed calls are not your first priority. The point of the discount is to keep the number defensible, not to sell a fix. Want the monthly version of this method with sources? Read what unanswered calls cost.
The formula, in text
Monthly revenue at stake = missed calls per week × weeks per month × (share of missed calls that become jobs ÷ 100) × average job value.
Conservative monthly estimate = monthly revenue at stake × (1 − confidence discount ÷ 100). The annual estimate is the conservative monthly figure × 12.
“Close rate” here is the end-to-end share of missed calls that would become booked jobs if answered and followed up. It is lower than a CRM close rate on handled leads, because many missed callers never return and not every missed call is a new inquiry.
Where each default comes from
| Input | Default | Status | Source or reason |
|---|---|---|---|
| Missed calls per week | 10 | Assumption | Worked-example value only. Set your own number from your call log; no external benchmark is substituted here. |
| Weeks per month | 4.33 | Assumption | Calendar average: 52 weeks ÷ 12 months. |
| Share of missed calls that become jobs | 13% | Assumption | Derived from the published method in our missed-call guide: 70% never return × 60% are new inquiries × 30% book when handled well ≈ 12.6%, rounded to 13%. It is not an industry benchmark. |
| Average job value | $800 | Assumption | Worked-example value only. Use your invoice average or median, in your own currency. |
| Confidence discount | 25% | Assumption | Sits inside the guide's suggested 20–30% conservative range; set it to 0 to see the unadjusted estimate. |
| Currency | USD | Assumption | Display symbol only. Choose your currency and enter the job value in the same one; the arithmetic does not change. |
No default on this page is an industry claim about your business. Every one is either labelled an assumption with its reasoning, or linked to the source of the method behind it.
Questions about the calculator
What formula does this calculator use?
It multiplies missed calls per week by weeks per month, then by the share of missed calls that become jobs, then by your average job value. All five inputs (including the confidence discount) are editable, and every default is labelled as an assumption or linked to a source.
Are the default numbers based on industry data?
No. The missed-call count and job value defaults are worked-example assumptions, not benchmarks. The 13% missed-to-job default is derived from the method in our missed-call guide: 70% of missed callers never return, 60% of the remainder are real new inquiries, and 30% of those book when handled well, which is about 12.6%, rounded to 13%. Replace every default with your own call logs and invoices.
Is the result a forecast or a guarantee?
No. It is an estimate built from your inputs and the assumptions shown beside them. The confidence discount exists to keep it conservative. Actual outcomes depend on your market, response times, follow-up and capacity, and we promise no recovery or revenue.
Does the calculator store or send my numbers?
No. The maths runs in your browser and nothing is submitted or stored. Only if you use the copy-link button are your numbers encoded in the URL you copy, and only you decide whether to share it.
Want eyes on your actual numbers?
If the estimate is worth investigating, the next step is a free lead-leak audit: a 15-minute strategy call and a written map of where leads leak in capture, response, booking and follow-up. No obligation and no outcome promises — and if automation is not your fastest win, we will tell you.
Prefer to see the first fix? The missed-call text-back workflow is usually the cheapest place to start. Build pricing is published on the pricing page (Automation Starter from $495, fixed in writing after the audit).
