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 vs late
Worked example
Inputs
- Total stops
- 200
- Late stops
- 12
- SLA target
- 95%
Outputs
- OTD%
- 94.00%
- Max late stops to hit 95%
- 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 windows95–99%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 complaintsUsually the last 5–10% of stopsLate 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.
