Formula
How the calculation works
Compound interest is applied at the chosen frequency, so quarterly compounding earns a little more than yearly on the same rate.
The maturity amount is the principal grown over the years, and the total interest is simply that minus the principal.
The effective annual yield shows what the compounding adds to the quoted rate, which is the number to compare between products.
Common mistakes
- Comparing the headline rate without checking the compounding frequency, when the effective yield is the fairer number.
- Forgetting that interest is usually taxed, which lowers the return you actually keep.
When to use it
- Use it to compare two deposits with the same rate but different compounding, or to see the value at maturity.
- It is not a tax calculator; enter the rate you actually receive after any deduction.
Worked example
Depositing 100,000 at 8% for 5 years compounded quarterly gives 148,594.74 at maturity, 48,594.74 in interest and an effective annual yield of 8.24%.
Common questions
Does compounding frequency really matter?
Yes, more frequent compounding earns slightly more interest, which is why the effective yield here is above the stated 8%.
Is the interest taxable?
This calculator shows gross interest; tax on FD interest is deducted separately, so the amount you keep will be lower.
