📈 Example Calculation

Let’s walk through a practical example:

  • Principal Amount: $5,000
  • Annual Interest Rate: 6%
  • Years: 10
  • Compounds per Year: 4 (quarterly)

When you click Calculate, the calculator uses the compound interest formula:

iniCopyEditA = P * (1 + r/n)^(nt)

Where:

  • A is the future value
  • P is the principal
  • r is the annual interest rate
  • n is the number of times interest is compounded per year
  • t is the number of years

For the above example:

iniCopyEditA = 5000 * (1 + 0.06/4)^(4*10)  
A = 5000 * (1.015)^40 ≈ $9,037.62

So, your investment will grow to $9,037.62 in 10 years with quarterly compounding.
