Pick a certification. This index fuses how fast it recovers its cost against the target job's pay with how exposed that job is to AI, into a single Durability Grade.
Two axes, both from public data. Cost recovery is the certificate cost expressed as a fraction of one month of the target occupation's median pay (BLS OEWS, May 2024). AI durability is one minus the target occupation's AI-task exposure, from published research (Eloundou et al. 2024 in Science; the Anthropic Economic Index).
The final score weights durability more heavily than payback, because almost every certificate recovers its cost quickly, so the scarce, decision-relevant signal is whether the job survives. The tool never estimates a salary increase; individual uplift is not knowable and is never claimed.
