CBAM Calculator

The only tool compatible with EC acts from December 2025

The CBAM Green Reporting calculator uses the correct FAA methodology – taking into account free allocations, benchmarks, and phase-in factor. The old calculation may underestimate your actual cost even 40 times.

WARNING!

From 1 January 2026, the import of CBAM goods requires Authorised Declarant status. 

First annual declaration to 30 Września 2027 r. and the cancellation of certificates to  August 31, 2027 

Don't leave calculations to the last minute.

 

Why is it important?

The simplified "2,5% tax" calculation ignores the FAA mechanism and the EC's product benchmarks. The consequences are serious.

Consequences of incorrect methodology

7–40×

The actual cost of CBAM is higher than the old, simplified calculation. The actual estimated cost should be included in the budget.

50+ EUR/t

The penalty for each missing CBAM certificate, plus the company's reputation, is a huge operational and strategic risk.

CBAM benchmark

Q1 2027 is the deadline for the first payment for certificates. Without including the benchmark, you won't be able to calculate your tax correctly.

What do you get?

A calculator built on the correct methodology

Full FAA Methodology
