What is Fixed Deposit (FD)?
A Fixed Deposit (FD) is a financial instrument provided by banks and NBFCs in India that offers a higher interest rate than a regular savings account. When you open an FD, you deposit a lump sum amount for a fixed tenure ranging from 7 days to 10 years. The money earns guaranteed interest at a predetermined rate.
Fixed deposits are one of the safest investment options in India as bank FDs up to ₹5 lakhs are insured by DICGC. They offer predictable returns and are ideal for conservative investors seeking capital preservation with steady income.
How FD Interest is Calculated
FD interest is calculated using compound interest formula. Most banks compound interest quarterly, though some offer monthly or yearly compounding.
A = P × (1 + r/n)^(n×t)
- A = Maturity Amount
- P = Principal (Initial Deposit)
- r = Annual Interest Rate (decimal)
- n = Compounding Frequency per year
- t = Tenure in years
Example FD Calculation
- Principal: ₹1,00,000
- Interest Rate: 7% p.a.
- Tenure: 5 years
- Compounding: Quarterly
- Maturity Amount: ₹1,41,478
- Total Interest: ₹41,478
Factors Affecting FD Returns
- Interest Rate: Higher rate means more returns; rates vary by bank and tenure
- Tenure: Longer tenures often get higher rates up to a point
- Compounding Frequency: More frequent compounding yields higher returns
- Type of FD: Cumulative FDs give higher effective returns than non-cumulative
- Depositor Category: Senior citizens get 0.25-0.50% extra interest
