📚 What are Compound Interest?

💰 What are Compound Interest?

Compound interest is interest calculated on the initial principal plus any accumulated interest from previous periods. It's the famous "interest on interest" effect.

📊 Compound Interest Formula

A = P × (1 + r)^n + C × ((1 + r)^n - 1) / r

  • A = Final amount (Future Value)
  • P = Initial principal
  • r = Interest rate per period
  • n = Number of periods
  • C = Periodic contribution

đŸŽ¯ Rule of 72

Time to double = 72 / Interest Rate

Example: With a 10% annual rate, your money doubles in approximately 7.2 years.
