Parking a ₹5 lakh lump sum in a 1-year fixed deposit is one of the most common ways Indian savers get a guaranteed, low-risk return on idle cash.
The Scenario
- Principal amount: ₹5,00,000
- Interest rate: 7% per annum
- Tenure: 12 months (1 year)
- Compounding: Quarterly, cumulative payout at maturity
The live result above is computed using the exact same compound interest formula the Fixed Deposit Calculator applies — the real output for this principal, rate, and tenure.
What This Means
Because interest compounds quarterly rather than just once a year, the effective annualised yield on this FD comes out a little above the nominal 7% rate — a small but real benefit of more frequent compounding that's easy to overlook when comparing FD rates across banks. Over just 12 months the total interest earned is modest relative to the principal, which is the expected trade-off for the safety and liquidity an FD offers compared to market-linked options over the same period.
