    on time delivery rate calculator

    On-time delivery rate calculator

    Calculate your OTD% (on-time delivery rate) and see how many late stops you can afford at different SLA targets.

    Summary

    • Calculates OTD% from total stops and late stops
    • Shows how many late stops you can allow for a target SLA%
    • Useful for weekly reporting and route comparisons
    • Use it to prioritize fixes: planning, dispatch, or execution issues

    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.
    On-time delivery rate (OTD%)
    94%
    On-time stops: 188 / 200
    To hit 95% SLA, max late stops: 10

    If you’re barely missing your SLA, you don’t need a total overhaul—find the top 1–2 causes of lateness (route planning time, long stops, failed deliveries) and fix those first.

    Benchmarks / ranges

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

    • OTD% for tight time windows
      95–99%
      Higher targets often require more buffer and cost.
    • OTD% for broad windows (half-day)
      90–97%
      Depends on customer expectations and density.
    • Late stops that trigger customer complaints
      Usually the last 5–10% of stops
      Late stops cluster late in routes; focus there.

    What to do next

    • Break OTD% down by route and driver to find where lateness clusters.
    • If lateness is end-of-day: reduce stop count per route or start routes earlier.
    • If lateness is random: reduce planning time and improve dispatch visibility.
    • Improve stop notes (access, contact, drop-off preference) to reduce time lost at stops.
    • Track failed deliveries separately—reattempts can destroy OTD%.
    • Recalculate weekly and monitor whether fixes actually move OTD%.

    Improve on-time delivery with Lynxo

    OTD% improves when routes are realistic and customers/sites are prepared. Lynxo supports both.

    • Live route monitoring so dispatch can prevent delays
    • ETA updates and notifications to reduce missed handoffs
    • Exception workflows (no access, customer not available) with evidence
    • Analytics for late-stop patterns by driver/area/time

    Where this helps

    • Tracking delivery SLA performance
    • Comparing routes, teams, and regions
    • Finding the biggest reliability gaps

    FAQs

    What counts as on-time?

    Most teams define on-time as arriving within the promised time window (or within a grace period). Use one consistent definition for reporting.

    What’s a good on-time delivery rate?

    It depends on your promise and market. Many ops teams aim for 95%+ for tight delivery windows, but the right target depends on cost and customer expectations.
