Total Project Cost

$205,632

Cost per Port

Step by step

  1. Values used

    Switches or nodes = 20 units; Hardware cost per unit = 6,500 currency; Ports per unit = 48 ports; Software licence per unit = 900 currency; Cabling and optics = 22,000 currency; Installation labour = 160 hours; Labour rate = 85 currency/hour; Contingency = 12 %

  2. Network Cost

    total = (units × (hardware + licence)) + cabling + (labour hours × rate), plus a contingency percentage of that subtotal.

  3. Total Project Cost

    = 205,632

  4. Hardware and Licences

    = 148,000

  5. Installation Labour

    = 13,600

  6. Contingency Reserve

    = 22,032

  7. Cost per Port

    = 214.20

How it works

Project cost is a sum of four independent buckets, and contingency is applied to the subtotal rather than to hardware alone because labour and cabling overruns are the more common surprise. Normalising by port count gives the figure that makes competing designs comparable. Cost per port is the number procurement and finance actually compare, and it is the only way to show that a cheaper switch with fewer ports is not cheaper at all.

Formula

Network Cost

total = (units × (hardware + licence)) + cabling + (labour hours × rate), plus a contingency percentage of that subtotal.

Frequently Asked Questions

How is Network Cost calculated?

total = (units × (hardware + licence)) + cabling + (labour hours × rate), plus a contingency percentage of that subtotal. Project cost is a sum of four independent buckets, and contingency is applied to the subtotal rather than to hardware alone because labour and cabling overruns are the more common surprise. Normalising by port count gives the figure that makes competing designs comparable.

Why does Network Cost matter?

Cost per port is the number procurement and finance actually compare, and it is the only way to show that a cheaper switch with fewer ports is not cheaper at all.

What values do I need to enter?

This calculator takes 8 inputs: Switches or nodes, Hardware cost per unit, Ports per unit, Software licence per unit, Cabling and optics, Installation labour, Labour rate, Contingency. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
