What a Missed Call Actually Costs a Home Services Business

There's no shortage of statistics claiming some percentage of callers never call back after reaching voicemail. The numbers vary enough between sources that we're not going to quote one. You don't need an industry average — you need your own number, and it's not hard to build.

The worksheet

Four inputs, all of which you either know or can pull from your phone system.

1. Missed calls per week. Most VoIP and call-tracking systems report missed and abandoned calls. If you don't have that, count for two weeks: calls that rang out, hit voicemail, or were abandoned on hold. Call this M.

2. Share of missed calls that are new business. Not every missed call is a job — some are suppliers, spam, or existing customers who'll call back. From a sample of answered calls, estimate the fraction that are prospective customers looking to book work. Call this p (a decimal, e.g. 0.5).

3. Your booking rate on a live prospective call. Of prospective callers your team actually talks to, what share become a scheduled job? You may know this; if not, 0.3–0.5 is a common range to sanity-check against. Call this b.

4. Average job value. Your average invoice, or average first-job value if you want to be conservative. Call this V.

The calculation

Weekly lost booked revenue ≈ M × p × b × V × (recapture factor)

The recapture factor accounts for the fact that some missed callers do call back or leave a message you convert. If you have no idea, use 0.6 — assume you're permanently losing about 60% of the missed prospective calls. Adjust once you have better data.

Worked example. A plumbing company misses 40 calls a week (M = 40). Roughly half are prospective customers (p = 0.5). They book 40% of live prospect calls (b = 0.4). Average job is $450 (V = 450). Recapture factor 0.6.

40 × 0.5 × 0.4 × 450 × 0.6 = $2,160 per week, or about $112,000 a year in booked revenue that never gets booked.

Change the inputs to yours. Even halving every assumption leaves a number most owners find uncomfortable.

Why the number is usually higher than it looks

• Emergency calls skew the average up. The 2am no-heat call is a premium-rate job, and it's exactly the kind that goes to voicemail. Your missed calls aren't a random sample of your job mix — they're weighted toward after-hours and overflow, which are weighted toward emergencies.
• Missed calls cluster on your busiest days. Storms and cold snaps drive call volume up on the same days your techs are already booked solid. That's when the most calls go unanswered and when each one is most likely to be real.
• A lost first job is a lost customer, not a lost invoice. The recapture factor only counts the first job. The customer who booked with a competitor because you didn't pick up also isn't calling you for the next one.

What to do with the number

If the annual figure is larger than what 24/7 coverage would cost — and for most established home services businesses it is, by a wide margin — the decision isn't really about whether to cover the phones. It's about whether to hire for nights and overflow (and pay for a lot of idle time) or hand those hours to a service that triages by your emergency criteria and dispatches your on-call tech for the real ones.

The takeaway

Don't argue about industry averages. Run four of your own numbers, get your annual figure, and compare it to the cost of never missing a call again. The worksheet takes ten minutes and the answer is usually not close.
