CBAM Cost Calculator for
A free estimate of the CBAM cost EU buyers face on goods of India origin, year by year from 2026 to 2034. The calculator compares Commission default values, including the mark-up, with verified actual emissions, and shows the saving that verified data delivers at the negotiation table.
Estimate the CBAM cost
Free and instant. Results never sit behind a form.
Select the product and the annual volume. The calculator estimates the certificate cost the EU buyer faces each year to 2034, on Commission default values or on verified actual data.
The certificate price is prefilled at 75.36 EUR per tCO2, the official Q1 2026 price. The Commission sets it quarterly for 2026 and weekly from 2027. INR figures use an approximate conversion of 110 INR per EUR, June 2026.
Estimate only. The figures use the simplified phase-in calculation described in the methodology section. The actual liability depends on verified emissions data, the free-allocation benchmark, the importer's declarations and implementing acts still being finalised. Nothing here is legal or financial advice.
How the estimate is calculated
Four factors, every one published
The covered goods shipped to the EU each year, in tonnes. The Carbon Border Adjustment Mechanism prices the embedded emissions these goods carry across the border.
Tonnes of CO2e per tonne of goods. Verified installation data gives the measured figure. Without it, the buyer falls back on Commission default values per product and country, set in Implementing Regulation (EU) 2025/2621, carrying a mark-up of 10 percent in 2026, 20 percent in 2027 and 30 percent from 2028. Fertilisers carry a flat 1 percent.
The fraction of embedded emissions that becomes payable, phasing in as free allocation for EU producers phases out: 2.5 percent in 2026, rising every year to 100 percent in 2034.
The importer surrenders one CBAM certificate per tonne of payable CO2e, priced off EU ETS auctions. The official Q1 2026 price stands at 75.36 EUR per tCO2, set quarterly for 2026 and weekly from 2027.
One disclosed simplification: the full regulation also deducts a free-allocation benchmark and any carbon price effectively paid at origin. The benchmark narrows as free allocation phases out, and the India deduction stands at zero under the draft rules published in May 2026, so the calculator applies the payable share to the full embedded emissions, a conservative reading most published estimators share.
The constants behind the figure
Every number traces to a published source
The payable share follows the free-allocation phase-out written into EU law. The schedule below drives the year columns in the calculator and compounds against the default mark-up, which is why early figures look small and 2030 onward does not.
| Year | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 |
|---|---|---|---|---|---|---|---|---|---|
| Payable share | 2.5% | 5% | 10% | 22.5% | 48.5% | 61% | 73.5% | 86% | 100% |
The certificate price tracks EU ETS auctions and publishes on the Commission price page, quarterly for 2026 and weekly from 2027. The prefilled value updates as new official figures publish.
A worked example
Steel, 500 tonnes a year
An Indian mill ships 500 tonnes of flat-rolled steel to an EU buyer each year. Without verified data the buyer applies the India default of 4.28 tCO2e per tonne plus the mark-up. With a verified intensity of 2.20 tCO2e per tonne, the same shipment carries roughly half the certificate bill. At the Q1 2026 price of 75.36 EUR the years compare as follows.
| Year | Default values with mark-up | Verified at 2.20 tCO2e/t | Saving from verified data |
|---|---|---|---|
| 2026 | € 4,435 | € 2,072 | € 2,363 |
| 2027 | € 9,676 | € 4,145 | € 5,531 |
| 2030 | € 101,681 | € 40,205 | € 61,476 |
| 2034 | € 209,652 | € 82,896 | € 126,756 |
The gap is the price of unverified data, and it compounds as the payable share rises. Measurement and verification typically cost a fraction of the saving from the first full year onward.
Default values or verified data
What the comparison means for an exporter
Defaults overstate by design
The Commission sets default values conservatively so embedded emissions are never underestimated, then adds a mark-up that reaches 30 percent from 2028. An efficient plant pays for the inefficiency of the national average.
Verified data is the lever
A measured, verifiable intensity below the marked-up default cuts the buyer's certificate bill in every year of the phase-in. The saving lands in the price negotiation.
Buyers ask for the data anyway
CBAM declarations need installation-level emissions data from the supply chain. Exporters that hold audit-ready numbers answer in days, not quarters.
The gap compounds
The payable share rises every year to 100 percent in 2034, and the default mark-up rises with it. A gap of thousands of euros today becomes lakhs by the early 2030s.
