PQC Migration Tool

Estimate your PQC migration cost

A planning tool by Ugo Chirico, author of Q-Day — Surviving the quantum revolution. Get a baseline estimate in under a minute, refine it with advanced inputs, download a detailed PDF.

Step 1 — Quick assessment 5 questions, ~1 minute. You'll receive a baseline estimate; an optional advanced step refines it.

Number of employees — proxy for IT estate complexity.

Compliance burden and cryptographic intensity vary dramatically by sector.

How pervasive is cryptography in your stack?

Can your systems swap algorithms without re-architecting?

When must you be PQC-compliant?

These figures are indicative ranges based on industry benchmarks (NIST, ENISA, mid-market migration studies 2024–2026). Actual costs depend on specific cryptographic inventory, vendor choices, and internal labor rates. Use as planning aid, not as final budget.

Step 2 — Advanced parameters

These optional inputs refine the estimate based on your specific cryptographic stack.

Estimate of systems/applications that use cryptography in any form.

Do you operate HSMs, smart cards, hardware tokens?

Formal certifications add audit and validation costs.

In-house teams cost less per FTE but ramp slower; consultants accelerate but cost more.

Multi-jurisdiction deployments add coordination and compliance overhead.
