Calculate investment growth with compound interest and regular contributions
Albert Einstein allegedly called compound interest "the eighth wonder of the world." It's the process where your investment earns returns, and those returns earn returns, creating exponential growth over time.
The longer your money compounds, the more dramatic the growth. Starting early is far more powerful than contributing more later. A 25-year-old investing $200/month will have more at 65 than a 35-year-old investing $400/month.
The more frequently interest compounds, the faster your money grows. Daily compounding yields slightly more than annual compounding. Regular monthly contributions also accelerate growth significantly.
