Calculate the interest earned and maturity amount for Fixed Deposits (FD). Compare returns for different time periods and rates.
Calculate maturity amount for Fixed Deposits.
The Fixed Deposit (FD) Calculator is your essential tool for planning secure, guaranteed-return investments. Fixed Deposits—known as Term Deposits or Certificates of Deposit (CDs) in some countries—are among the safest investment vehicles offered by banks and NBFCs (Non-Banking Financial Companies). When you open an FD, you deposit a lump sum for a predetermined period at a fixed interest rate, ensuring predictable returns regardless of market volatility.
Unlike market-linked investments such as stocks or mutual funds, FDs provide capital protection and guaranteed returns. Your principal is secure (insured up to ₹5 lakh by DICGC in India or $250,000 by FDIC in the USA), and you know exactly how much you'll receive at maturity. This makes FDs ideal for risk-averse investors, emergency fund parking, short-term goals, or retirees seeking stable income through monthly/quarterly interest payouts.
In 2026, with interest rates stabilizing after recent increases, FDs offer attractive returns of 6-8% p.a. for most tenures. Senior citizens typically receive an additional 0.25-0.50% rate bonus. Understanding how compounding frequency, tenure, and tax implications affect your returns is crucial for maximizing your FD investment—and that's exactly what this calculator helps you do.
Simple Interest FD (Rare):
Compound Interest FD (Standard):
A = Maturity amount (principal + interest)
P = Principal (initial deposit)
r = Annual interest rate (as decimal, e.g., 7% = 0.07)
n = Compounding frequency per year (12=monthly, 4=quarterly, 1=annual)
t = Time period in years
The compounding frequency significantly impacts your final maturity amount. Here's how ₹1,00,000 grows at 7% p.a. over 5 years with different compounding:
| Compounding | Frequency (n) | Maturity Amount | Total Interest | Effective Rate |
|---|---|---|---|---|
| Annual | 1 | ₹1,40,255 | ₹40,255 | 7.00% |
| Quarterly | 4 | ₹1,41,478 | ₹41,478 | 7.19% |
| Monthly | 12 | ₹1,41,762 | ₹41,762 | 7.23% |
Monthly compounding yields ₹1,507 more than annual compounding on ₹1 lakh over 5 years. Most banks in India use quarterly compounding.
Understand how Fixed Deposits compare to other popular investment choices:
| Feature | Fixed Deposit | Savings Account | Recurring Deposit | Mutual Funds |
|---|---|---|---|---|
| Returns (2026) | 6-8% p.a. | 3-4% p.a. | 6-7.5% p.a. | 8-15% (varies) |
| Risk Level | Very Low | Very Low | Very Low | Low to High |
| Liquidity | Low (penalty on early withdrawal) | High | Low | Medium to High |
| Investment Type | Lump sum | Flexible | Monthly SIP | Lump sum or SIP |
| Capital Guarantee | Yes (insured) | Yes (insured) | Yes (insured) | No |
| Best For | Short-term goals, emergency fund | Daily expenses | Regular savings habit | Long-term wealth building |
| Tenure | Public Sector Banks | Private Banks | Small Finance Banks | NBFCs/Corporate FDs |
|---|---|---|---|---|
| 7 days - 45 days | 3.0-4.0% | 3.5-4.5% | 4.0-5.5% | 4.5-6.0% |
| 46 days - 6 months | 4.5-5.5% | 5.0-6.0% | 5.5-7.0% | 6.0-7.5% |
| 6 months - 1 year | 5.5-6.5% | 6.0-7.0% | 6.5-7.5% | 7.0-8.0% |
| 1 - 2 years | 6.0-6.8% | 6.5-7.25% | 7.0-8.0% | 7.5-8.5% |
| 2 - 5 years | 6.0-6.5% | 6.5-7.0% | 7.0-7.75% | 7.5-8.5% |
| 5+ years | 6.0-6.5% | 6.0-6.75% | 6.5-7.5% | 7.0-8.0% |
Senior citizens typically receive 0.25-0.50% additional interest. Corporate FDs and NBFC FDs offer higher rates but carry slightly higher risk. Always verify deposit insurance coverage.
❌ Breaking FD before maturity: Premature withdrawal typically incurs a 0.5-1% interest rate penalty. Banks may pay 1-2% less than your contracted rate. For emergency funds, consider FD laddering or liquid funds instead.
❌ Not comparing rates across banks: FD rates vary significantly—Small Finance Banks may offer 1-2% higher than large public banks. Use comparison websites and check multiple banks before locking in.
❌ Ignoring tax implications: With 30% tax bracket, a 7% FD yields only 4.9% post-tax. Compare this to tax-free alternatives like PPF (7.1%) or ELSS mutual funds. Consider tax-saver FDs for Section 80C benefits.
❌ Putting all money in one FD: FD laddering (multiple FDs with staggered maturities) provides liquidity, rate optimization, and reduces reinvestment risk. Split ₹5 lakh into five ₹1 lakh FDs with 1-5 year tenures.
❌ Not reviewing renewal terms: Auto-renewed FDs often get lower rates than new deposits. Set calendar reminders before maturity to compare rates and decide on reinvestment.
Regulatory Information & Sources: FD calculations use standard compound interest formulas recognized by RBI (Reserve Bank of India) and FDIC (Federal Deposit Insurance Corporation). In India, bank deposits up to ₹5 lakh are insured by DICGC (Deposit Insurance and Credit Guarantee Corporation) under the RBI. In the USA, deposits up to $250,000 are insured by FDIC. Interest rates shown are indicative for 2026 and vary by institution. TDS provisions as per Income Tax Act. Always verify current rates and terms with your financial institution before investing.

A Fixed Deposit (FD) is a secure investment instrument offered by banks and financial institutions where you deposit a lump sum for a fixed tenure at a predetermined interest rate. Unlike savings accounts, FD rates remain locked for the entire term, protecting you from rate fluctuations. Interest is earned through compounding—your interest earns interest—calculated quarterly, monthly, or annually depending on the bank. For example, ₹1 lakh at 7% p.a. compounded quarterly for 5 years grows to ₹1.41 lakh. FDs are insured up to ₹5 lakh (India) or $250,000 (USA/FDIC), making them among the safest investment options available.
FD maturity is calculated using the compound interest formula: A = P × (1 + r/n)^(n×t), where P = principal amount, r = annual interest rate (as decimal), n = compounding frequency per year (4 for quarterly, 12 for monthly, 1 for annual), and t = time in years. For simple interest FDs (rare): A = P × (1 + r × t). Example: ₹1,00,000 at 7.5% for 3 years with quarterly compounding: A = 1,00,000 × (1 + 0.075/4)^(4×3) = 1,00,000 × (1.01875)^12 = ₹1,24,903. The effective annual rate (EAR) with quarterly compounding is slightly higher than the nominal rate due to compounding benefits.
FD interest is fully taxable as 'Income from Other Sources' in most countries. In India: TDS of 10% applies if annual interest exceeds ₹40,000 (₹50,000 for senior citizens). Without PAN, TDS is 20%. You can submit Form 15G/15H if your total income is below taxable limits to avoid TDS. 5-year Tax Saver FDs qualify for Section 80C deduction up to ₹1.5 lakh. In the USA: FD (CD) interest is reported on Form 1099-INT and taxed as ordinary income at your marginal rate. Consider tax-advantaged accounts like IRAs for CDs to defer taxes. Always factor in post-tax returns when comparing FD vs other investments.
