MFA Rollout Payback with mfa rollout investment of 212,500 $: a worked example

This scenario runs the mfa rollout payback calculation on the strong side: mfa rollout investment of 212,500 $, with every other input held at its documented default. Use it when evaluating MFA for vendor portals, jump hosts, engineering access, and privileged OT accounts.

The inputs for this scenario

  • MFA rollout investment: 212,500 $ (raised for this scenario; the documented default is 85,000)
  • Annual MFA risk reduction savings: 42,000 $ / yr (unchanged)
  • Annual MFA support cost: 9,500 $ / yr (unchanged)

Working through the calculation

  • Applying the documented formula (Net annual MFA savings = annual MFA risk reduction savings - annual MFA support cost) to the inputs above produces each figure below.
  • At this operating point the engine returns 6.54 yr for mfa rollout payback period, the number this scenario is built around.
  • At this operating point the engine returns 32,500 $ / yr for net annual mfa savings.
  • At this operating point the engine returns 212,500 $ for mfa rollout investment.
  • At this operating point the engine returns -50,000 $ for five-year net mfa value.

How this compares with the baseline

  • Against the tool's baseline example, where mfa rollout investment sits at 85,000 $ and the headline result is 2.62 yr, this scenario comes in 150% above the baseline at 6.54 yr.
  • Use it when building or defending the business case for an MFA program across IT, OT, or remote-access systems, before committing to a vendor and rollout plan. Treat this as a target state: the delta against the baseline quantifies what the improvement is worth before you commit to chasing it.

Results at a glance

  • MFA rollout payback period: 6.54 yr (headline result)
  • Net annual MFA savings: 32,500 $ / yr
  • MFA rollout investment: 212,500 $
  • Five-year net MFA value: -50,000 $
