Formula proof
What the calculator is doing
- Embedded CO2e = import quantity x emission factor.
- Effective carbon price = max(0, CBAM certificate price - recognised origin carbon price).
- Net CBAM cost = embedded CO2e x effective carbon price.
- Certificates required = net cost divided by CBAM certificate price.
Important boundary
This is a planning calculator. Real declarations require current official prices, verified emissions where applicable and professional customs compliance review.
Source carried in
Initial factors, countries, revision text and compliance copy were derived from Billy's local CBAM HTML source file, then converted into the CalculationTime staged page system.
Revision notes
Staged version 0.1
Ported from `frombilly/cbam-calculator.html` into a native React page with the shared CalculationTime hero, staged noindex metadata, product category controls, live result panel, sensitivity table and formula proof.
Needs final source review before canonical promotion
Do not treat default ETS prices, origin carbon prices or legal timing text as live market advice until they are checked against current official sources.

The CBAM calculator estimates embedded emissions, certificate requirements, carbon price offsets and net import cost from the visible import inputs.
Formula applied
The exact method behind this answer
CalculationTime keeps the method visible so the number can be checked instead of blindly trusted.
Estimated CBAM cost = embedded CO2e x max(EU ETS certificate price - eligible origin carbon price, 0).- Apply the methodEstimated CBAM cost = embedded CO2e x max(EU ETS certificate price - eligible origin carbon price, 0).Embedded CO2e x net certificate priceThe result depends on import quantity, emissions basis, ETS price and eligible origin carbon price offset.

Assumptions used
What this answer assumes
These boundaries keep the calculation honest and make clear when a specialist rule set is needed.
- This staged page is an arithmetic estimator, not legal or customs advice.
- Emission factors, product scope and reporting rules must be checked against current EU CBAM guidance.
- Currency, certificate price and origin carbon price offsets can change over time.
- The staged page remains noindex until Billy approves a canonical release.
Master’s Tip
How to use the result well
Master’s Tip: keep product category, quantity basis, emission factor source and price date together. CBAM estimates become weak when the source basis is separated from the number.
Printable record
What belongs in the saved calculation
If an import carries 120 tCO2e, the EU ETS price is EUR 75/t and an eligible origin carbon price is EUR 20/t, the net CBAM rate is EUR 55/t and the estimated cost is EUR 6,600.
