Last Mile Delivery Capacity Calculator
Estimate daily last mile delivery capacity from controllable resource, production-rate, time, and completion assumptions. The calculator distinguishes theoretical output from practical planned capacity, then shows how much output is removed by the selected operating factor. Use it to compare staffing, door, route, or schedule scenarios while keeping assumptions explicit. Actual throughput may also depend on demand timing, work mix, geography, labor availability, and downstream constraints.
Calculator
Capacity assumptionsFormula
Theoretical capacity = resources × rate × operating time
Practical capacity = theoretical capacity × operating factor
What the result means
Practical capacity is the modeled daily output after applying the operating factor. The planning reduction is the gap from the theoretical maximum.
This is a deterministic planning estimate. Model peak and normal scenarios separately and validate assumptions with observed data.
Example calculation
42 × 16 × 8 = 5376 theoretical units. Applying 88% gives 4731 practical units, a reduction of 645.
Tips for better results
- Use observed rates from a comparable work mix.
- Model peaks separately from averages.
- Keep the operating factor visible during reviews.
- Check upstream and downstream constraints.
- Recalculate after route, layout, or schedule changes.
Frequently asked questions
What does last mile delivery practical capacity represent?
It is the modeled output after applying the entered completion or productive-time percentage to theoretical capacity.
Why include an efficiency or completion factor?
It captures expected nonproductive time or incomplete planned work without changing the base resource and rate assumptions.
Can the factor be 100%?
Yes. That returns theoretical capacity, but it assumes every planned unit and time period produces at the entered rate.
Should peak and average rates be mixed?
No. Use rate, time, and factor assumptions from the same operating scenario.
Does calculated capacity guarantee demand can be served?
No. Constraints such as arrival timing, geography, product mix, labor skills, and downstream limits may reduce achievable output.
