Seven-day measurement guide
How many plumbing calls are you actually missing?
Review one week of your own phone logs instead of copying a broad industry percentage. A consistent seven-day baseline gives a small plumbing shop a more useful starting point for fixing the real call-handling gap.
No universal benchmark. No software required. No assumption that every missed ring was a customer.
The direct answer
Count the calls the shop had a fair chance to handle
Your missed-call rate is eligible missed inbound calls divided by eligible inbound calls. Both numbers need to cover the same defined period and follow the same inclusion rules.
Seven days is a practical starting sample, not a universal statistical standard. If the week included unusual weather, a holiday, a staff absence, or an abnormal rush, repeat the review and compare the results.
Define before you count
Decide what belongs in the denominator
There is no single mandatory accounting method for every shop. Write a rule that fits your phone setup and operating question, then use it consistently for the full week.
Usually eligible
Calls the business intends to handle
- New customer inquiries
- Existing customers needing service
- Genuine callbacks when they matter to the workflow
- Scheduling or rescheduling calls when they matter to the workflow
Exclude or classify separately
Calls that can distort the baseline
- Spam and robocalls
- Wrong numbers
- Vendors and suppliers
- Internal or team calls
- Obvious duplicate attempts from the same caller
- Abandoned calls that never gave the shop a realistic chance to answer, when identifiable
Seven-day worksheet
Record the same six counts every day
Review the phone log at the same time each day when possible. Fill in raw counts first; calculate percentages from the totals after Day 7.
| Day | Eligible inbound calls | Missed eligible calls | Missed new-prospect calls | Recovered missed calls | After-hours eligible calls | After-hours missed calls |
|---|---|---|---|---|---|---|
| Day 1 | Blank | Blank | Blank | Blank | Blank | Blank |
| Day 2 | Blank | Blank | Blank | Blank | Blank | Blank |
| Day 3 | Blank | Blank | Blank | Blank | Blank | Blank |
| Day 4 | Blank | Blank | Blank | Blank | Blank | Blank |
| Day 5 | Blank | Blank | Blank | Blank | Blank | Blank |
| Day 6 | Blank | Blank | Blank | Blank | Blank | Blank |
| Day 7 | Blank | Blank | Blank | Blank | Blank | Blank |
| Totals | Blank | Blank | Blank | Blank | Blank | Blank |
Missed new prospects: use “believed to be” when caller intent is not certain.
Recovered: define the real reconnection event you will count before the review starts.
After hours: use the exact closed-hours window from the shop’s stated schedule.
Calculate from the totals
Four rates, four different questions
Keep the raw counts with the percentages. A rate is easier to interpret when you can still see how many calls produced it.
Missed-call rate
The share of calls in your defined pool that the business did not answer.
New-prospect missed-call share
How much of the missed-call pool appears to involve prospective new customers.
Callback recovery rate
The share of missed calls that later reached a real response through your defined follow-up process.
After-hours missed-call rate
The missed share for the after-hours window you defined before counting.
Example only — not a benchmark
A fictional one-week calculation
Imagine a shop counts 60 eligible inbound calls, 12 missed eligible calls, 6 missed new-prospect calls, and 9 recovered missed calls. Eight eligible calls arrived after hours, and 6 of those were missed.
- Missed-call rate
- 12 ÷ 6020%
- New-prospect missed share
- 6 ÷ 1250%
- Callback recovery rate
- 9 ÷ 1275%
- After-hours missed rate
- 6 ÷ 875%
These percentages describe only the fictional week above. They are not a plumbing-industry target, average, or threshold.
Read the pattern
What your baseline can tell you
The useful question is not whether the result crosses a universal cutoff. Look for where the gap occurs, who it affects, and whether the current response process works.
When are calls being missed?
Compare active-job hours, office gaps, lunch, dispatch peaks, and after-hours periods.
Who is trying to reach the shop?
Separate likely new prospects from existing customers, scheduling calls, and other valid contacts.
Does follow-up reach them?
A returned call is not automatically recovered. Define recovery as an actual reconnection.
Is the issue concentrated after hours?
A separate after-hours view shows whether office-hours changes would address the real gap.
Would a small process fix cover it?
A named callback owner or immediate acknowledgment may be enough when the gap is narrow.
Does fuller coverage deserve evaluation?
Recurring, valuable, unrecovered calls may justify comparing additional coverage approaches.
Common measurement mistakes
Keep the baseline honest
Small classification errors can change what the final percentages appear to say.
- 01
Counting spam as leads
Keep spam, robocalls, and wrong numbers outside the eligible-call pool.
- 02
Treating every missed ring as a lost customer
A phone-system label does not tell you the caller’s intent or final outcome.
- 03
Ignoring duplicate attempts
Several calls from one person can otherwise look like several separate opportunities.
- 04
Combining all hours
Track business-hours and after-hours activity separately before comparing them.
- 05
Changing definitions midweek
Write the inclusion and exclusion rules first, then apply them to all seven days.
- 06
Calling every callback a recovery
Count a recovery only when the follow-up actually reconnects under your chosen rule.
- 07
Treating one unusual week as permanent
Repeat the review if weather, staffing, holidays, or call volume made the week atypical.
- 08
Trusting the “missed” label without checking it
Learn how your phone system handles abandoned calls, transfers, voicemail, and simultaneous rings.
Why Spidrr does not use one benchmark
Published percentages are rarely like-for-like
Reported missed-call percentages may combine different industries, business sizes, time windows, phone-system definitions, and denominators. A broad figure can provide context, but it should not be treated as the operating benchmark for a 2–5-person plumbing company. Your consistently measured call log is the evidence that should guide your next decision.
Use the measured input
Put your baseline into the calculator
Enter the missed-call rate you measured, then add your own call volume, new-prospect share, callback recovery, close rate, and job value. The result estimates possible exposure; it does not prove lost revenue or return on investment.
