About Fixed Deposit Calculator
The Fixed Deposit (FD) Calculator helps you project maturity value and interest on lump-sum FDs. Fixed deposits are widely used in India for predictable returns and capital safety, especially for conservative investors and senior citizens.
How this calculator works
Years or months: We use quarterly compounding (four times per year), which is common for cumulative bank FDs:
Maturity A = P × (1 + r/4)4t, where P is principal (rounded to whole rupees), r is annual interest as a decimal (rate % ÷ 100), and t is time in years (for months, t = months ÷ 12). Maturity is rounded to the nearest rupee; estimated returns = A − P.
Days: Very short tenures use a linear estimate so results scale evenly with principal (e.g. same rate and days on ₹1 lakh vs ₹1 crore):
Est. returns = round(P × R × d × 7 ÷ 250000), where R is the quoted annual rate in percent (e.g. 6.5) and d is the number of days. Total value = P + est. returns.
Time unit switch: If you change among years, months, and days, the same number is kept when it still fits the new range; otherwise it is clamped to valid min/max.
Disclaimer: Actual bank FDs may use different day-count or rounding rules. Use this tool for estimates only; confirm with your bank.
How FDs work (general)
Deposit: Banks often allow from about ₹1,000–₹10,000 minimum; tenures from a few days to 10 years. Rates vary by tenure and institution. Senior citizens often get a small extra rate.
Interest: Banks may compound quarterly, half-yearly, or yearly on cumulative FDs. TDS may apply if interest exceeds ₹40,000 in a year (₹50,000 for senior citizens); Form 15G/15H can help when applicable.
Withdrawal: Premature withdrawal is usually allowed with a penalty. Loan against FD is often available up to a large fraction of the deposit.
Benefits & features
- Predictable returns; DICGC insurance up to ₹5 lakh per depositor per bank (check current rules)
- Often materially higher than savings account rates
- Flexible tenures; optional payout frequencies on non-cumulative FDs
- Interest is generally taxable; tax-saver FDs (5-year lock-in) may qualify under Section 80C within limits
Who should use
Anyone comparing lump-sum FD options, planning short- to medium-term goals, or parking funds with low volatility tolerance.
Important considerations
Limitations: Post-tax returns may trail inflation; interest is usually taxable; breaking FD early reduces yield; opportunity cost versus growth assets.
Example (quarterly, years)
₹5,00,000 for 3 years at 7% p.a. (quarterly): Maturity about ₹6,15,562; interest about ₹1,15,562. Actual figures depend on bank rules and rounding.
FAQs
Why quarterly for years/months on this page?
Many cumulative FDs in India compound interest quarterly. This calculator uses that single convention for year- and month-based tenures so projections are easy to compare.
Should I break my FD if rates rise?
Only if the new rate after penalty still beats staying put. Penalties vary by bank and tenure.
Is FD rate fixed for tenure?
Yes, locked at booking. Market rate changes don't affect existing FD.
Monthly income from FD?
Choose non-cumulative, interest paid monthly/quarterly. Lower total returns than cumulative FD.
FDs better than savings accounts?
For money you do not need immediately, FDs often pay noticeably more than a regular savings rate, but they come with tenure and early-withdrawal rules.
