Debt can impact economic growth, but there may be a tipping point where it starts to harm the economy. In European Union countries from 1995 to 2019, high government debt above 111.6% of GDP can slow down growth. Private debt, like from companies and households, can also affect growth, with thresholds at 149.8% and 138.3-145.1% of GDP respectively. This means that too much debt can hurt the economy, but if managed well, it can help with spending and investment.
