Use your own numbers
People, identities, capacity, reserve, price, horizon, replacement rate and annual management costs remain adjustable.
YUBIKEY COST SCENARIO
Turn identity architecture into a transparent cost scenario.
Enter your own assumptions and compare key demand, hardware cost and annual management licences. The result is a planning aid—not a quotation and not a claim that every identity should share one key.
VALUE IN 30 SECONDS
A calculation that makes every assumption visible.
Compare two scenarios
The baseline assumes one identity per physical key; the second scenario uses a selected number of identities per key.
Keep security in control
The calculation never decides which roles may share hardware. That remains an architecture and policy decision.
FROM ROLES TO HARDWARE DEMAND
Which assumptions actually determine the number of security keys?
Procurement cost becomes understandable when identity count, permitted consolidation, reserve and expected replacement are calculated separately instead of hidden in a single estimate.
-
01
Count people and identities
Begin with the number of users and the average number of distinct PIV identities or roles each person needs.
-
02
Set permitted identities per key
Enter the consolidation level your architecture permits, not the largest technical value available.
-
03
Add reserve and replacement
Include spare hardware and an annual replacement assumption so the result covers more than the first issue day.
-
04
Compare hardware and total cost
Review the physical-key delta, hardware cost, management licences and total cost, then validate the security assumptions.

How the calculation works
Key requirement = initial requirement + reserve + expected replacement. Reserve = initial requirement × reserve %. Replacement = initial requirement × annual replacement % × years. Total cost per scenario = key requirement × unit price + annual management licence cost × years.
Initial guidance, not a quotation. One-off implementation costs, services, taxes, shipping, accessories and operational expenditure are not included. The permitted identities per key must be validated against the hardware, cryptography and your security policy.
TECHNICAL DEPTH
How the scenario is calculated.
The formula is deliberately simple and visible. It supports an initial decision conversation without pretending to replace a detailed rollout and lifecycle calculation.
- One-identity-per-key baseline
- People × identities per person produces the initial baseline quantity. Reserve and the selected replacement factor are then applied.
- Multi-identity scenario
- Identities per person are divided by the selected identities-per-key capacity and rounded up per person. Reserve and replacement are applied to the resulting physical-key count.
- Hardware, licence and total difference
- The quantity difference is multiplied by the unit price. The freely entered annual management licence for each scenario is then applied over the selected period.
