Zero Trust MFA ROI Calculator

Gauge whether multi-factor authentication under a zero-trust rollout will pay for itself. Enter your covered headcount and the per-user license cost, then estimate breach probability and impact to surface total spend, avoided loss, ROI, and the risk reduction needed to break even.

Total employees, contractors, and admins who will enroll.
Include authentication and device-trust modules in this rate.
Defaults to a 12-month contract if blank.
Use published cost-of-breach data or your insured loss model.
Reflects likelihood of a credential-based breach without MFA.
Enter the expected percentage drop in breach probability.
Implementation, hardware tokens, or consulting fees.

Security ROI estimates are directional; validate inputs with your risk, finance, and security teams.

Examples

  • 1,200 users at $6.50 per month, 12-month term, $4.45M breach, 15% baseline risk, 35% reduction, $10k launch ⇒ ROI 108.58% with $1.05M avoided loss.
  • 800 users at $4.80 per month, defaults for other fields ⇒ investment $46,080, avoided loss $192,600, ROI 317.87%, payback 2.9 months.

FAQ

Can I change the term length?

Yes. Update the term months field to reflect multi-year deals or short pilots. Blank defaults to 12 months.

What does break-even risk reduction mean?

It is the percentage drop in breach probability required so that expected loss avoided equals total MFA spend. Achieving more than this reduction yields positive ROI.

Does this cover productivity benefits?

No. It focuses on avoided breach losses. Add additional savings to the launch field if you want to capture soft benefits such as faster logins or reduced helpdesk calls.

How should I pick breach cost?

Use your insurer’s modeling, Ponemon Institute data, or recent internal incident cost. Include legal, response, downtime, and reputational expenses.

Additional Information

  • Baseline breach probability and reduction percentages can come from cyber-insurance underwriting or internal risk assessments.
  • Include implementation and hardware token costs to avoid underestimating cash outlay.
  • Expected loss avoided multiplies breach cost by baseline probability and the percentage reduction MFA delivers.
