Compound Interest Calculator – See Your Money Grow Fast

What is Compound Interest?

• In simple words: Interest on your interest.
• Your money earns interest → next time, that interest also earns interest → repeat.
• Over time, this creates exponential growth in savings, investments, or even debts.
• Formula for compound interest: A=P(1+r/n)n×t. Where:
  • A = Final amount after time
  • P = Initial amount (principal)
  • r = Annual interest rate (decimal form)
  • n = Number of times interest is compounded per year
  • t = Number of years
