NextGenEu has the potential to increase the EU's real GDP by up to 1.4% in 2026, compared to a situation without the instrument. In 2022 the estimated additional growth was 0.4%, compared to the 1.9% expected in 2020.

The figure does not include the expected stimulus of reforms, which takes place in the long term and which the Commission expects to have a "significant impact" in the future. The Commission's economic models suggest that NextgenEu could boost the EU GDP by as much as 1.8% by 2026.
