- Interest is shown before tax. Banks may deduct tax at source and may differ in how they compound, so check your deposit terms.
How fixed deposit interest compounds
With compounding, interest is added to the deposit at set intervals and then earns interest too. More frequent compounding gives a slightly higher maturity amount at the same quoted rate.
The effective yearly return shows what the quoted rate really gives after compounding, which makes two deposits easier to compare.
Banks differ in how they compound and pay interest, and tax may apply to the interest, so check the terms of the deposit.
The formula
Maturity = amount × (1 + r ÷ n)^(n × years), where r is the yearly rate as a decimal and n is the number of times interest is compounded each year.
Common questions
How is FD maturity calculated?
Maturity = amount × (1 + rate ÷ compounding periods) raised to compounding periods × years. The calculator does this and lists each year.
Does compounding frequency matter?
Yes, a little. The same rate compounded monthly gives slightly more than compounded yearly. The effective yearly return shows the difference.
Is the interest shown before or after tax?
Before tax. Tax on interest depends on your income, so check with your bank or accountant.
Is this financial advice?
No. It is arithmetic on the numbers you enter.
