Smart Locker Sizing & Operating Cost Calculator
Estimate how many locker doors you need, allocate small, medium and large compartments, and develop an indicative five-year operating budget.
Build a defensible locker specification.
Designed for UK smart locker buyers. Adjust the blue input fields to see your estimate update immediately. Figures are illustrative planning assumptions, not a Vpod quotation.
Peak demand & dwell time
Choose the sizing method that fits your workflow.
Method note: Flow × dwell is a steady-state estimate. For short event surges, examine actual arrivals and departures in 15–30 minute periods before ordering.
Compartment mix
Share of occupied demand by required door size.
Size categories are illustrative. Validate usable internal dimensions, accessibility, door opening and cabinet configuration.
Indicative commercial assumptions
Edit these placeholders to match supplier quotes.
Cost warning: Placeholder prices are user-editable modelling assumptions, not verified Vpod prices. VAT, finance, power and site-specific works may not be included unless entered.

Live values update with every change. Illustrative assumptions are not a supplier quotation.
How this is calculated
Required doors = peak occupied demand × (1 + growth allowance) ÷ target design occupancy. Door sizes are allocated from the demand mix with integer rounding. Prices and labour value are estimates.
Understand the numbers behind your locker specification.
Estimate peak demand
Compare arrivals, dwell time and actual concurrent occupancy before setting capacity.
