Reinvestment refers to the act of using profits earned from an investment to boost that same investment. Some synonyms for reinvestments include reinvestment income, reinvestment rate, reinvestment risk, compound interest, or capital appreciation. Additionally, "rollovers" can also imply the reinvestment of an asset into a similar or related investment. Alternatives such as compound interest and capital appreciation specifically refer to the benefits of reinvesting rather than the act itself. Reinvestment can help investors increase their returns over time, as their profits begin to generate even greater profits, known as compounding. Overall, reinvesting can be a crucial component of long-term financial success, and the synonyms for the term all reflect this understanding.
