Compound Interest Rate Calculator

Υπολογισμός επιτοκίου δανείου (ανατοκισμός)

Compound interest is the interest calculated on the initial principal and also on the accumulated interest from previous periods. Essentially, it’s “interest on interest” and helps investments or savings grow at a faster rate compared to simple interest, where interest is only calculated on the principal amount.

The formula for compound interest is:

[ A = P \left(1 + \frac{r}{n}\right)^{nt} ]

Where:

  • ( A ) is the amount of money accumulated after n years, including interest.
  • ( P ) is the principal amount (initial investment).
  • ( r ) is the annual interest rate (in decimal form).
  • ( n ) is the number of times that interest is compounded per year.
  • ( t ) is the time the money is invested or borrowed for, in years.

Compound interest can significantly increase the growth of your savings or investments over time.
