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 82.32 EUR per tCO2, the official Q3 2026 price published on 5 October 2026. 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 follow the method described in the next section, with benchmarks held at their 2026 values and the certificate price entered applied to every year. The actual liability depends on whether the declaration uses verified actual data or default values, on revised benchmarks and on any carbon price deduction. Nothing here is legal or financial advice.
How the estimate is calculated
Four steps from tonnes to euros
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 adjustment mirrors the free allocation EU producers of the same good still receive, except for electricity, where it is zero. On default values it is the good's CBAM benchmark, times the CBAM factor for the year, times the cross-sectoral correction factor, times the mass imported. The deduction shrinks each year. The CBAM factor is 97.5 percent in 2026, 95 percent in 2027, 90 percent in 2028 and 77.5 percent in 2029. It falls to 51.5 percent in 2030, 39 percent in 2031, 26.5 percent in 2032 and 14 percent in 2033. From 2034 nothing is deducted for free allocation.
The declarant surrenders certificates for the embedded emissions minus the free allocation adjustment, priced off EU ETS auctions. The official Q3 2026 price stands at 82.32 EUR per tCO2, set quarterly for 2026 and weekly from 2027.
Benchmarks stay at their 2026 values in every year, because revised benchmarks for imports from 1 January 2027 are expected but had not been adopted by 15 October 2026. The certificate price entered applies to every year. With verified data, the default benchmark for the product, or for the route chosen where there is a choice, stands in for the process benchmarks and precursors the law uses. The calculator leaves out any carbon price deduction. The questions below explain when a deduction can apply.
The constants behind the figure
Every number traces to a published source or a stated assumption
Article 10a(1a) of the EU ETS Directive sets the CBAM factor, the share of the benchmark still deducted each year. The schedule below drives the year columns in the calculator. In 2026, 2.5 percent of the benchmark is no longer deducted. That figure is not 2.5 percent of the embedded emissions. Implementing Decision (EU) 2026/1862 sets the cross-sectoral correction factor at 100 percent for each year from 2026 to 2030. No value is set for later years, so the calculator assumes 100 percent to 2033.
| Year | 2026 | 2027 | 2028 | 2029 | 2030 | 2031 | 2032 | 2033 | 2034 |
|---|---|---|---|---|---|---|---|---|---|
| Share of the benchmark still deducted (CBAM factor) | 97.5 percent | 95 percent | 90 percent | 77.5 percent | 51.5 percent | 39 percent | 26.5 percent | 14 percent | 0 percent |
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
Example: an Indian mill ships 500 tonnes of hot-rolled flat steel (CN 7208) to an EU buyer each year. On default values in 2026, the India default of 4.280 tonnes of CO2e a tonne, with the 10 percent mark-up, gives 4.708, or 2,354 tonnes for the shipment. The free allocation adjustment is 0.975 x 1.00 x 1.370, or 1.336 a tonne, which takes off 668. The declarant surrenders 1,686 certificates. With a verified intensity of 2.20 tCO2e per tonne, the calculator keeps the same adjustment and the declarant surrenders 432. The table prices every tonne at the third-quarter 2026 price of 82.32 EUR, as if all of it were imported in that quarter. In 2030 it holds the price and the benchmark at their 2026 values.
| Year | Default values with mark-up | Verified at 2.20 tCO2e/t | Saving from verified data |
|---|---|---|---|
| 2026 | € 138,792 | € 35,562 | € 103,230 |
| 2030 | € 199,955 | € 61,493 | € 138,462 |
The gap is the price of unverified data. It widens until 2028 as the mark-up rises, then holds at the same price. In this example the saving is the gap in the table. Whether it exceeds the cost of measurement and verification depends on the plant.
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. It reaches 30 percent from 2028, except for fertilisers, which stay at 1 percent. 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 can answer buyer requests faster.
The gap widens with the mark-up
For cement, iron and steel, aluminium and hydrogen, the default mark-up rises from 10 percent in 2026 to 30 percent from 2028. The gap between default and verified figures widens with it. The fertiliser mark-up stays at 1 percent. The deduction shrinks every year to 2034, so the bill itself keeps growing.
