MFA Rollout Payback with mfa rollout investment of 42,500 $: a worked example

Here is what the math looks like when conditions slip. We hold every other input steady and drop mfa rollout investment to 42,500 $, then walk the calculation through step by step. Estimate payback for MFA rollout on OT remote access and privileged access paths.

The inputs for this scenario

  • MFA rollout investment: 42,500 $ (the input this scenario stresses; the baseline uses 85,000)
  • Annual MFA risk reduction savings: 42,000 $ / yr (held at the documented default)
  • Annual MFA support cost: 9,500 $ / yr (held at the documented default)

Working through the calculation

  • The calculation starts from the formula this tool documents: Net annual MFA savings = annual MFA risk reduction savings - annual MFA support cost.
  • MFA rollout payback period works out to 1.31 yr at these inputs, and this is the headline figure for the scenario.
  • Net annual MFA savings works out to 32,500 $ / yr at these inputs.
  • MFA rollout investment works out to 42,500 $ at these inputs.
  • Five-year net MFA value works out to 120,000 $ at these inputs.

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 50% below the baseline at 1.31 yr.
  • The practical read: the gap between this scenario and the baseline is entirely attributable to mfa rollout investment, so recovering it is worth quantifying in dollars before considering equipment or staffing changes. The result is only as credible as the risk-reduction savings input, which is an actuarial estimate (breach probability x impact) rather than a measured cash flow, so document your assumptions.

Results at a glance

  • MFA rollout payback period: 1.31 yr (headline result)
  • Net annual MFA savings: 32,500 $ / yr
  • MFA rollout investment: 42,500 $
  • Five-year net MFA value: 120,000 $
