This study aims to analyze the effect of Zakat, Infaq, and Sadaqah (ZIS) funds, investment, and inflation on economic growth in Indonesia during the 2002–2022 period. Economic growth is an important indicator in measuring the success of national development and is influenced by various economic and social factors. This research employed a quantitative approach using secondary data obtained from the Central Statistics Agency (BPS), Bank Indonesia (BI), and the National Amil Zakat Agency (BAZNAS). The data were analyzed using multiple linear regression with the assistance of EViews software. The results indicate that Zakat, Infaq, and Sadaqah (ZIS) funds and investment have a positive effect on Indonesia’s economic growth. Meanwhile, inflation also affects economic growth, where controlled inflation can support economic activities, but high inflation has the potential to hinder economic growth. Simultaneously, ZIS funds, investment, and inflation significantly influence economic growth in Indonesia. This study demonstrates that Islamic economic instruments and macroeconomic factors are interconnected in encouraging national economic growth. The findings are expected to serve as a reference for the government and related institutions in formulating more inclusive, stable, and sustainable economic policies.
