IIoT, SCADA & Edge Connectivity calculator

Gateway Support Cost Calculator

Estimate annual edge gateway support cost. Enter the deployed gateway count, support cost per gateway-year (firmware, fleet monitoring, on-call), the share of gateways under active support contract, and a fixed central support team cost. The calculator returns variable support spend and the loaded total.

What this calculator does

  • 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.
  • Use it when an OT support lead is sizing the recurring support bill for a deployed edge gateway fleet (IoT Greengrass, Inductive Edge, Cisco IR1101, Siemens IOT2050) before the next budget cycle.
  • It returns the annual loaded support cost for a deployed edge gateway fleet, broken into variable per-gateway support and a fixed central team line.

Formula used

  • Variable gateway support cost = deployed gateways × support cost per gateway-year × share under active contract
  • Total gateway support cost = variable support cost + fixed central support team cost

Inputs explained

  • Deployed edge gateways: Use the count of edge gateways deployed and active in the fleet management console.
  • Support cost per gateway-year: Include vendor support contract, firmware updates, fleet monitoring tool share, and on-call labor amortized per gateway (typical 60 to 250 dollars per gateway-year).
  • Share of gateways under active support contract: Use the share with an active support contract (the rest are usually self-supported and lower cost).
  • Fixed central support team cost: Include the OT support team labor, fleet management platform subscription, and central NOC tooling shared across the gateway fleet.

How to use the result

  • Use it before the next budget cycle, when planning a fleet expansion, or when comparing in-house support against a managed gateway service.
  • It is a recurring support view. It does not size capital replacement; build a separate replacement schedule based on gateway lifecycle.

Common questions

  • What is in cost per gateway-year? Vendor support contract, firmware update labor, fleet monitoring tool share, and on-call labor per gateway. Typical 60 to 250 dollars depending on gateway class.
  • Why scale by share under active contract? Some plants self-support older gateways. Scaling avoids over-counting support spend on gateways the team is just running to failure.
  • Should I include cellular SIMs in this calculator? No. SIMs and data are usage costs; use the MQTT data cost or industrial network bandwidth calculators.
  • How do I model a managed-service offer? Plug the managed-service per-gateway price into cost per gateway-year, set share to 100 percent, and zero out fixed central team cost. Compare totals.
