FDR Calculator

What a bank fixed deposit pays at maturity.

Formula

How the calculation works

An FDR is a lump sum left with a bank for a fixed term, with the profit credited each quarter. The tool compounds it quarterly for the same reason a certificate does: the credited profit then earns in the next quarter, and that is what the bank's own maturity figure reflects.

Because the arithmetic is identical to a certificate, the only thing that separates two FDR offers is the rate and the term. Enter the rate you are actually quoted rather than a remembered one, since these move with policy.

Common mistakes

• Reading the maturity value as pure profit. The 130,605 on the worked example includes the 100,000 you put in; the profit is the 30,605.
• Forgetting that tax is withheld at source on the profit. The figure here is before tax, so the amount credited will be lower.

When to use it

• Use it to compare FDR offers at different rates and terms, and to see the compounding effect over longer terms.
• It is not for a monthly savings plan; for that use the DPS calculator, where each instalment earns for a different length of time.

Worked example

100,000 in an FDR at 9% for 3 years: 130,605.00 at maturity, interest 30,605.00.
