Choice IQ readout
The effective annual rate is higher than the nominal rate whenever interest compounds more than once a year. That gap is why two products quoting the same rate can pay different amounts.
- Compare products on effective annual rate, not the headline number.
- Indian FDs compound quarterly, most savings accounts quarterly, and many bonds half-yearly.
- This ignores tax. Add your slab rate to compare after-tax outcomes fairly.
Tool guide
How to use this compound interest calculator india
Two products quoting the same rate can pay different amounts, because how often interest compounds changes the outcome. This calculator shows the effective annual rate alongside the nominal one, and compares the result against simple interest so the gain from compounding is visible rather than assumed.
Formula
Amount = principal x (1 + rate / frequency)^(frequency x years). Effective annual rate = (1 + rate / frequency)^frequency - 1.

FAQ
What is the difference between nominal and effective rate?
The nominal rate is the headline annual figure. The effective rate is what you actually earn once compounding within the year is counted. A 8% rate compounded quarterly gives an effective rate of about 8.24%.
How often do Indian banks compound interest?
Fixed deposits and savings accounts generally compound quarterly. Some bonds and small savings schemes compound half-yearly or annually. Always check, because it changes the comparison between two similar-looking rates.
Does this account for tax?
No. It shows the pre-tax figure. Interest income is usually taxed at your slab in India, so reduce the effective rate accordingly when comparing against tax-free options like PPF.
