The 168-Hour Front Desk: How to Work Out What Your Phone Coverage Actually Costs

A business week is 168 hours. Set your real ones in step 1 and the four steps after it count the gap, price it, and draw it closed — every number from your own inputs, nothing stored.

  1. Set your real hours

    A business open 9 to 5 on weekdays posts 40 hours. Posted and covered are different numbers, and the gap between them is where the argument lives.

    Your week, as one barPost your open hours, then subtract the lunch hour, the stretches when everyone is with someone and the phone rings out, and the days nobody backfills the desk. Every figure below follows these two numbers.

    A caller reaches a personPosted open, phone unansweredClosed — voicemail or nothing

    Starting values are the guide's example — a weekday 9–5 that loses the lunch hour — not a finding about your business. Nothing you enter here is stored or sent anywhere.

    The rest is not idle time. It is the time your number is still being dialled.

  2. See where the dark hours fall

    Missed calls aren't spread evenly. They cluster, each cluster behaves differently, and only two of the four leave anything behind.

    Your 133 dark hours, by where they fallThe same hours as the bar above, split into the four clusters they land in. Only the solid ones leave anything behind.

    After close80 hrs

    VoicemailThe biggest block — and more often a new customer researching than a regular rescheduling.

    Weekends48 hrs

    VoicemailA voicemail left Saturday morning is answered Monday. That's 48 hours to call someone else.

    Lunch and busy stretches5 hrs

    No recordShort, frequent, and logged nowhere.

    Overflow

    No recordTwo calls at once. The second one waits; a caller comparing options doesn't.

    Weeknights and weekends are counted from your posted hours on the assumption they fall Monday to Friday. The coverage clock takes a real Saturday.

    A report of missed calls is a floor, not a count — half the gap never reaches it.

  3. Price the gap with your own figures

    Two numbers from your own records, one judgement call, one multiplication. A model you can't check is a model you won't act on.

    The whole calculation, four stepsChange any number and the rest follow.

    An estimate from your numbers, not a promise. Some missed callers ring back and some leave a voicemail — both push it down, neither to zero.

  4. Compare the four ways to close it

    Once the gap is hours and dollars, the four options compare. While it's a feeling, they don't.

    Which one is right depends on the gap you just measured — which is why measuring it first is the actual advice here.

  5. See the week with the gap closed
