Last-Mile Delivery Density Calculator — Route Efficiency Optimiser
Calculate your delivery density to understand route efficiency. Stops per square mile, time per stop, and how density affects your cost per delivery.
Quick answer: Urban delivery: 40–80 stops/day per route. Suburban: 20–40. Rural: 8–20. Higher density = lower cost/stop. Every 10% increase in stops/route reduces cost/stop by ~8–12%.

How to Use This Calculator
- Enter stops and route area — to calculate delivery density (stops per square mile).
- Enter daily route costs — driver, vehicle, and fuel — the denominator for cost per stop.
- Enter target stops — to quantify annual savings from adding stops through better territory management.
Worked Example
35 stops/day, 12 sq mi, $220 driver, $95 vehicle, $45 fuel, target 42 stops.
- Density: 35 ÷ 12 = 2.9 stops/sq mi
- Cost/stop: $360 ÷ 35 = $10.29
- At 42 stops: $360 ÷ 42 = $8.57/stop
- Annual savings: ($1.72 × 42) × 250 = $18,060
Route optimisation software typically increases stops per route by 10–20% while reducing drive time — paying back in months.
