Gateway Support Cost at 61% share of gateways under active support contract: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop share of gateways under active support contract to 61%, then walk the calculation through step by step. Estimate annual edge gateway support cost from the deployed gateway count, support cost per gateway-year (firmware, monitoring, on-call), the share of gateways under active support contract, and a fixed central support team cost.

The inputs for this scenario

  • Deployed edge gateways: 320 gateways (held at the documented default)
  • Annual support cost per gateway: 180 $ / gateway-year (held at the documented default)
  • Share of gateways under active support contract: 61 % (the input this scenario stresses; the baseline uses 85)
  • Fixed central support team cost: 55,000 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Variable gateway support cost = deployed gateways × support cost per gateway-year × share under active contract.
  • Total gateway support cost works out to 90,136 $ at these inputs, and this is the headline figure for the scenario.
  • Support cost per gateway works out to 282 $ / piece at these inputs.
  • Variable gateway support cost works out to 35,136 $ at these inputs.
  • Fixed central support team cost works out to 55,000 $ at these inputs.

How this compares with the baseline

  • Against the tool's baseline example, where share of gateways under active support contract sits at 85% and the headline result is 103,960 $, this scenario comes in 13.3% below the baseline at 90,136 $.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to share of gateways under active support contract, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. It assumes a single average per-gateway support rate; in reality costs vary by gateway model, site, and connectivity, and it excludes one-time replacement or major upgrade capital.

Results at a glance

  • Total gateway support cost: 90,136 $ (headline result)
  • Support cost per gateway: 282 $ / piece
  • Variable gateway support cost: 35,136 $
  • Fixed central support team cost: 55,000 $
