Definition

Interest that’s calculated on both your initial principal and the interest that has been added over time. It helps your money grow faster.

What to consider

  • Starting early can make a huge difference in your savings growth.
  • Small, regular contributions really add up over time.
  • Keep the power of compounding in mind as you plan for the future.

Real world scenarios

  • After graduating, Ronnie invests a small amount each month into an index fund. Over the years, compounding accelerates his returns, helping his portfolio grow far beyond his initial contributions.
  • Jenny opens a high-yield savings account and reinvests the interest. Each interest payment adds to her balance, which then generates even more interest the next cycle.
  • Realizing the power of compound interest, Marcus starts saving early for retirement. He watches his investments multiply faster than simple interest would allow.
