This detailed calculator applies the CBAM free-allocation-adjusted method (Article 31, Reg. (EU) 2023/956): you are charged only for emissions above the still-free benchmark share, which shrinks each year. It is more accurate than a flat estimate — enter your installation’s figures, or override the benchmark and default value with your CN-code values.

Method. Free-allocation-adjusted per Article 31, Reg. (EU) 2023/956:
You pay only for emissions above the still-free benchmark share, which falls from 97.5% (2026) to 0% (2034). Benchmarks: IR (EU) 2025/2620. Default values: IR (EU) 2025/2621. Certificate price: European Commission.

Indicative. Exact benchmark and default values are set per CN code in the cited regulations; the certificate price varies quarterly; this is not a substitute for a verified CBAM determination. Need the figures applied to your installation and verified? See the CBAM Exposure Screening.
