How to Use This Calculator
  1. Enter total users requiring MFA enrollment.
  2. Select MFA method (TOTP app, SMS, hardware token, push notification, or FIDO2 passkey).
  3. Set rollout timeline (months) and spare tokens (%) for replacements.
  4. Review hardware cost, implementation cost, monthly recurring, and first-year total cost.
  5. FIDO2 passkeys have the lowest long-term cost and highest phishing resistance -- prioritize for privileged users.

What each input means

Total users
Number of users who will be enrolled in MFA.
MFA method (0-4)
0 = SMS OTP ($0.50/user/mo + SMS fees), 1 = Authenticator app ($1), 2 = Push ($2), 3 = Hardware token/YubiKey ($3 + $50 token), 4 = Biometric ($4 + $80 reader).
Rollout timeline (months)
Phased deployment timeline. Longer rollout reduces disruption but extends elevated support costs.
Spare tokens (%)
Extra hardware tokens to purchase as spares (only applies to hardware token and biometric methods).

What each result means

Monthly recurring ($)
Monthly licensing and per-authentication costs (SMS fees if applicable).
Hardware cost ($)
One-time cost for hardware tokens or biometric readers including spares.
Implementation cost ($)
Training and IT setup costs (IdP configuration, policy creation, testing).
First year total ($)
All-in first year: hardware + implementation + 12 months licensing + rollout help desk.
Annual ongoing ($)
Year 2+ costs: licensing + steady-state help desk + 5% hardware replacement.
Cost per user/month ($)
Fully loaded first-year cost divided by users and 12 months.
Monthly help desk tickets
Expected steady-state MFA-related help desk tickets per month (~1% of users).

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total users = 500, MFA method (0-4) = 1, Rollout timeline (months) = 3, Spare tokens (%) = 10 = 4 input(s) provided
  2. Calculate Monthly recurring
    Monthly recurring = monthlyLicensing + monthlySmsCost
    500 = $500
  3. Calculate First year total
    First year total = totalHardwareCost + trainingCost + setupCost + rolloutHelpDeskCost +
    23725 = $23,725
  4. Calculate Hardware cost
    Hardware cost = users * hardwareCostPerUser * spareMultiplier
    0 = $0
  5. Calculate Implementation cost
    Implementation cost = trainingHours * 50
    15850 = $15,850
