Compound Interest Formula

The standard compound interest formula is:

A = P × (1 + r / n)nt

Where:

  • A = Final amount
  • P = Principal amount
  • r = Annual interest rate in decimal form
  • n = Number of compounding periods per year
  • t = Investment period in years

Compound interest can be calculated as: Compound Interest = A − P.

What Is Compound Interest?

Compound interest is interest calculated on the original principal as well as the interest accumulated during previous periods. Because the accumulated interest can itself earn interest, the investment value may increase faster over longer periods.

The effect becomes more noticeable as the investment period increases and interest is compounded more frequently.

Compounding Frequency Explained

Interest is added once per year. This is represented by a compounding frequency of 1.

Half-Yearly Compounding

Interest is compounded twice per year.

Quarterly Compounding

Interest is compounded four times per year.

Monthly Compounding

Interest is compounded twelve times per year.

Interest is compounded approximately 365 times per year.
