Most tradies guess they miss a few calls a week. They rarely guess how much those calls are worth. Here's how to calculate your real number - and why it's probably higher than you think.
A homeowner's hot water system just died. It's 7am, they're late for work, and they need a plumber today. They Google "emergency plumber near me" and call the first three results.
You're one of those three. But you're already under a house on another job. Your phone rings twice and goes to voicemail.
They don't leave a message. 62% of callers won't leave voicemail - they just call the next number. The second plumber answers. Job booked. That's $1,200 gone in 15 seconds.
Now multiply that by every missed call you had this month.
Here's the formula:
Your Cost Per Missed Call:
Average Job Value x Conversion Rate = Cost Per Missed Call
Most tradies convert between 30-50% of enquiries into jobs. So if your average job is $800 and you convert 40% of callers, each missed call costs you $320.
But what does that look like over a week? A month? A year? Here's the breakdown:
| Avg Job Value | 3 Missed/Week | 5 Missed/Week | 10 Missed/Week | 15 Missed/Week |
|---|---|---|---|---|
| $300 | $18,720/yr | $31,200/yr | $62,400/yr | $93,600/yr |
| $500 | $31,200/yr | $52,000/yr | $104,000/yr | $156,000/yr |
| $800 | $49,920/yr | $83,200/yr | $166,400/yr | $249,600/yr |
| $1,200 | $74,880/yr | $124,800/yr | $249,600/yr | $374,400/yr |
| $2,000 | $124,800/yr | $208,000/yr | $416,000/yr | $624,000/yr |
Based on 40% conversion rate and 52 weeks per year. Your actual numbers will vary - but the pattern holds.
Find the row closest to your average job value. Now find the column closest to how many calls you miss per week. That's the revenue you're leaving on the table every year.
Reality Check:
A plumber averaging $800 jobs who misses 5 calls per week is losing roughly $83,200 per year. That's a ute, a holiday, and a healthy super contribution - gone.
The table above only covers the direct job revenue. But every missed call has a ripple effect that makes the real cost even higher.
A happy customer tells 2-3 people about you. An unhappy one (including someone who couldn't reach you) tells 10. Every job you win generates future work through word of mouth. Every missed call kills that chain before it starts.
No job means no review. And reviews are what push you higher on Google Maps, which brings more calls, which brings more jobs. It's a compounding cycle - and missed calls break it.
That $800 hot water job? If you do good work, that customer calls you for every plumbing issue for the next 10 years. Blocked drains, tap replacements, bathroom renos. One customer could be worth $5,000-$15,000 over their lifetime. A missed call doesn't just lose you one job - it loses you a customer for life.
Not all missed calls are equal. Some trades get hit harder than others.
Plumbers, electricians, locksmiths, HVAC - When someone's toilet is flooding or power is out, they're calling right now. They won't wait for a callback. The first tradie to answer wins 100% of the time.
Estimated cost per missed call: $400-$1,200+ (emergency premium pricing)
Builders, landscapers, bathroom renovators - These callers might be more patient, but the job values are massive. Missing a $30,000 renovation enquiry because you were on another call is brutal.
Estimated cost per missed call: $2,000-$12,000+ (based on project conversion rates)
Cleaners, pest control, pool service, gardeners - Individual job values are lower, but these customers come back weekly or monthly. Missing the first call means losing years of recurring revenue.
Estimated cost per missed call: $150-$400 per job, but $2,000-$8,000 in lifetime value
Stop Leaving Money on the Table
MethodisAI answers every call for your trade business - 24/7, weekends, and public holidays. No more missed revenue.
Stop guessing. Here's how to work out exactly what missed calls are costing you:
22 x $650 x 0.40 = $5,720/month
That's $68,640 per year in lost revenue. For a one-man operation, that's transformative money.
Once you see the number, you can't unsee it. The good news is there are solutions at every price point - from free to a few hundred dollars a month.
We wrote a complete guide covering 7 different approaches ranked by cost and effectiveness: How to Stop Missing Calls as a Tradie (Without Hiring Staff).
The short version: any solution that catches even 2-3 extra jobs per month will pay for itself many times over. The ROI on answering calls is one of the highest in any trade business.
The Minimum Viable Fix:
At the very least, update your voicemail greeting to set expectations and send an auto-SMS to missed callers. It takes 10 minutes and costs almost nothing. But if you're serious about growth, look into proper call answering solutions.
Missed calls aren't a minor inconvenience. For most trade businesses, they're one of the biggest revenue leaks - silently costing tens of thousands of dollars per year.
The tradies who are growing fastest aren't necessarily better at their trade. They're better at answering the phone.
Calculate your number. Look at it. Then decide if you can afford to keep ignoring it.
Most solo tradies and small crews miss between 5 and 15 calls per week. The number spikes during busy periods, after-hours, and when you're on the tools. Check your phone's call log for the last month to get your actual number.
Research shows 62% of callers won't leave a voicemail - they'll ring the next tradie on Google instead. Of the 38% who do leave a message, about half will have already booked someone else by the time you call back. So roughly 80% of missed calls are lost jobs.
Multiply your average job value by your conversion rate (typically 30-50% for tradies). For example, if your average job is $800 and you convert 40% of enquiries, each missed call costs you $320 in direct revenue - plus the hidden costs of lost referrals and reviews.
Emergency trades like plumbers, electricians, and locksmiths lose the most because their callers are urgent and will immediately ring a competitor. High-value trades like builders and HVAC installers also lose significantly due to larger job values per missed call.
The cheapest option is a professional voicemail greeting with a fast callback system, but 62% of callers won't leave a message. SMS auto-replies cost $20-100/month. AI call answering services like MethodisAI cost $200-600/month and answer every call 24/7 - often paying for themselves with just one extra job per month.
