What is an FD Calculator?

An FD (Fixed Deposit) calculator estimates the maturity amount of your fixed deposit based on the principal, interest rate, tenure, and compounding frequency. It helps you compare FD returns across banks and plan your finances accordingly.

Compound interest FD formula:

M = P × (1 + r/n)^(n×t)

Where M = maturity amount, P = principal, r = annual rate, n = compounding frequency per year, t = tenure in years.

FD vs Mutual Funds — The Honest Comparison

FD interest for someone in the 30% tax bracket is effectively 5.25% (at 7.5% gross). A debt mutual fund or arbitrage fund with similar risk often delivers better post-tax returns due to LTCG taxation at 20% (with indexation) for debt funds held over 3 years. Equity mutual funds offer significantly higher long-term returns with the caveat of market risk. FD's advantage is certainty — you know exactly what you will receive. But for wealth creation over 5+ years, FDs typically underperform inflation-adjusted returns.

Frequently Asked Questions

What is the tenure range for FDs in India?+
Fixed deposits can be opened for tenures ranging from 7 days to 10 years. Interest rates vary by tenure and lender.
Is FD interest taxable?+
Yes. FD interest is fully taxable as per your income slab. TDS at 10% is deducted if interest exceeds ₹40,000 per year (₹50,000 for senior citizens). This significantly reduces the effective return for those in the 30% tax bracket.
What is the difference between cumulative and non-cumulative FDs?+
Cumulative FDs reinvest the interest and pay at maturity (compound interest). Non-cumulative FDs pay interest at regular intervals (monthly, quarterly, annual). Cumulative FDs give higher maturity amounts; non-cumulative FDs provide regular income.
Are senior citizens given higher FD rates?+
Yes. Most banks offer 0.25 to 0.75% higher interest rates to senior citizens (60+). TDS exemption threshold is also higher at ₹50,000 per year.
Can I break an FD before maturity?+
Yes, but most banks charge a premature withdrawal penalty of 0.5 to 1% on the applicable rate. Some tax-saving FDs have a 5-year lock-in and cannot be broken early.
