What Is It and When Do You Need It?

A fixed deposit locks your money for a term and pays a fixed rate of interest. It is a low-risk choice for savers. Banks usually compound interest quarterly, so the actual yield is slightly above the quoted rate.

Enter the amount, rate and term, and choose the compounding to see what you will get at maturity.

How to Use This Tool

  1. Enter the deposit amount.
  2. Enter the interest rate.
  3. Enter the term in years and months.
  4. Choose compounding and press Calculate.

How the Calculation Works

The maturity amount is A = P × (1 + r ÷ n)^(n t), with the term in years including any months as a fraction of a year. Interest is A − P. The effective annual yield is (1 + r ÷ n)^n − 1.

Worked Example

100,000 at 7% compounded quarterly for 2 years and 6 months matures to about 118,944, giving interest of about 18,944 and an effective yield of 7.19%.

Tips and Common Mistakes
