    Drivers needed calculator

    Estimate driver count from your daily stops, stop time, and working hours—so you don’t overhire or miss SLAs.

    Summary

    • Estimates drivers needed from stops/day and time per stop
    • Includes a drive-time buffer per stop (simple but practical)
    • Helps plan peak days, new regions, and staffing
    • Use it to sanity-check route load before promising delivery windows

    Definitions

    Cost per stop
    Your total daily delivery cost divided by completed stops. Helpful for pricing and profitability.
    OTD% (On-time delivery rate)
    The percentage of stops delivered on time (within the promised window, or your chosen definition).
    Effective work minutes
    The realistic minutes a driver can spend delivering in a shift after breaks, loading, traffic, and end-of-day admin.
    Tip: subtract breaks, loading time, and end-of-day admin from shift length.
    Estimated drivers needed
    3
    Total route workload: 1200 min
    Minutes per stop (incl. buffer): 10 min

    If the estimate is tight, add buffer (traffic, loading, failed stops) before you promise narrow delivery windows. Understaffing shows up as late stops fast.

    Benchmarks / ranges

    These are conservative ranges. Your results depend on density, stops, traffic, and service type.

    • Minutes per stop (doorstep-style delivery)
      4–10 minutes
      Includes parking + handoff; varies by building type.
    • Minutes per stop (B2B receiving)
      8–20 minutes
      Dock waits and paperwork can dominate.
    • Effective work time in an 8-hour shift
      360–450 minutes
      Subtract breaks, loading, traffic, end-of-day admin.

    What to do next

    • If drivers needed jumps with small demand increases, your per-stop time or travel time is too high—tighten routes first.
    • Separate route types (dense neighborhoods vs long-distance) and plan capacity per type.
    • Track actual minutes per stop and adjust the buffer instead of guessing.
    • If you have time windows, add more buffer or plan additional routes—tight windows reduce flexibility.
    • Reduce failed stops with ETA windows and better stop notes (access, instructions).
    • Use the estimate to plan peak staffing and decide when to add a shift vs add drivers.

    • Planning staffing for peak days
    • Sizing a new delivery region
    • Evaluating whether you can offer same-day

    FAQs

    Does this include drive time between stops?

    This calculator focuses on stop handling time. If your routes have long travel time, add buffer minutes per stop or reduce effective working hours.

    How do time windows affect driver count?

    Tighter windows reduce flexibility and often increase drivers needed. Add buffer or plan for more routes.
