How to Use This Calculator

Enter the total number of IoT devices in your fleet.
Select a security tier: 1=Basic (TLS), 2=Standard (mTLS + SIEM), 3=Advanced (HSM + zero-trust).
Set firmware update frequency per year and whether formal compliance is required.
Enter dedicated security staff (FTE) and monthly incident-response retainer cost.
Review Upfront cost, Annual cost, and Cost per device per year to plan your security budget.

How the result changes with Device count

Device count: Total IoT devices in the fleet to be secured.
Security tier (1-3): 1 = Basic (TLS, passwords), 2 = Standard (mTLS, SIEM), 3 = Advanced (HSM, zero-trust, pen-test).
FW updates/year: How many firmware/security patches you push per year.
Compliance (0=no, 1=yes): Whether formal compliance certification is needed (IEC 62443, NIST, etc.).
Security staff (FTE): Dedicated IoT security staff (full-time equivalent).
IR retainer ($/mo): Monthly incident response retainer fee.

Upfront cost ($): One-time costs: hardware security, PKI setup, audits, compliance.
Annual cost ($): Yearly recurring security costs.
Cost/device/year ($): Annualized security cost per device (upfront amortized over 3 years).
PKI annual ($): Annual certificate management and renewal costs.
Monitoring annual ($): Annual SIEM / security monitoring platform costs.
Compliance cost ($): One-time compliance certification cost.

4 parameters
Device count = 1000, Security tier (1-3) = 2, FW updates/year = 4, Compliance (0=no, 1=yes) = 1 = 6 input(s) provided
Calculate Upfront cost
Upfront cost = secureHwTotal + certProvisioningTotal + firmwareSigningSetup + securityAuditC...
52000 = $52,000
Calculate Annual cost
Annual cost = pkiAnnualTotal + fwUpdateAnnual + siemAnnual + staffAnnual + incidentAnnual
149330 = $149,330
Calculate Cost/device/year
Cost/device/year = (totalUpfront / 3 + totalAnnual) / deviceCount
166.66 = $166.66
