IIoT, SCADA & Edge Connectivity calculator

Cloud Connectivity Payback Calculator

Estimate cloud connectivity payback. Enter the project cost (cellular SIM hardware and onboarding, SD-WAN appliance, fiber install, cloud IoT onboarding), the annual savings (truck rolls avoided, faster site onboarding, reduced VPN, cloud broker direct), and the annual recurring connectivity cost (cellular SIM monthly, SD-WAN subscription, cloud egress). The calculator returns net annual savings, payback in years, and the five-year net.

What this calculator does

  • Estimate the payback period in years on a cloud connectivity project (cellular SIM pool, SD-WAN, fiber upgrade, IoT cloud onboarding) from project cost, annual savings (avoided truck rolls, faster onboarding, reduced VPN), and annual recurring connectivity cost.
  • Use it when an OT network or cloud lead is justifying a cellular SIM pool or SD-WAN cloud onboarding investment for a multi-site OT footprint.
  • It returns the payback period in years and five-year net for a cloud connectivity investment across a multi-site OT footprint.

Formula used

  • Net annual cloud connectivity savings = annual savings - annual recurring cost
  • Cloud connectivity payback period = project cost รท net annual savings

Inputs explained

  • Cloud connectivity project cost: Include cellular SIM hardware and onboarding, SD-WAN appliances, fiber install, cloud IoT onboarding, and cybersecurity hardening.
  • Annual savings from cloud connectivity: Include avoided truck rolls (use the remote monitoring savings calculator), faster site onboarding, VPN cost reduction, and direct cloud broker savings.
  • Annual recurring connectivity cost: Include cellular SIM monthly fees, SD-WAN subscription, cloud broker egress, and platform support.

How to use the result

  • Use it before approving a cellular SIM pool, SD-WAN appliance order, or fiber retrofit, or when comparing cellular against on-prem fiber for the same use case.
  • Cellular bills carry overage and SIM rental fees that can swing the recurring cost line. Build a true cellular bill model before final sign-off.

Common questions

  • What savings are real for cloud connectivity? Truck rolls avoided through remote access, faster site onboarding (days instead of weeks), VPN appliance cost reduction, and direct cloud broker without an on-prem hop.
  • How does this differ from IIoT ROI? IIoT ROI covers the connected-machine business case. Cloud connectivity payback is specific to the network and onboarding layer beneath it.
  • What payback is acceptable? Plant capital usually wants 1.5 to 3 years. Multi-site cellular SIM pools often payback faster because they avoid per-site fiber install and VPN cost.
  • Should I include cybersecurity tooling cost? Yes. Cloud connectivity raises the cyber surface; include endpoint protection, identity, and zero-trust tooling in either project cost or recurring cost.
