Equity grew from SEK 1.6 billion in 1988 to SEK 18.3 billion at year-end 2023, while research grants totalling SEK 111 billion were approved in the same period.

Besides the original donation from the Bank of Sweden, RJ received further donations of SEK 1.5 billion, which increased the foundation's asset base, in 1993. Every year, RJ makes an allocation to tied-up capital from profit brought forward, to preserve the real original value of the donations. For the years 1989–2023 RJ has allocated SEK 2.5 billion, which corresponds to the rise in the consumer price index.

At the end of 2023, RJ had a strong financial position. RJ's Annual Reports disclose the foundation's return and financial result for each year.
