FD Calculator

Fixed Deposit (FD) is a financial instrument offered by banks and Non-Banking Financial Companies (NBFCs) in India where you deposit a lump sum amount for a fixed period at a predetermined interest rate. FDs are one of the most popular and safest investment options, offering guaranteed returns and capital protection.

When you open an FD, you agree to keep your money with the bank for a specific period (tenure), and in return, the bank pays you interest at a fixed rate. The interest rate is locked in at the time of deposit and remains constant throughout the tenure, regardless of market fluctuations.

FDs are ideal for conservative investors who want:

• Guaranteed returns with minimal risk
• Predictable income through regular interest payments
• Capital protection (up to $5 lakhs insured by DICGC)
• Flexible tenure options (from 7 days to 10 years)
• Higher interest rates for senior citizens

Our FD calculator helps you plan your fixed deposit investments by calculating the maturity amount and interest earnings before you invest.

Our FD calculator uses compound interest formula to calculate your fixed deposit maturity amount:

FD Calculation Formula: A = P(1 + r/n)^(nt)

Where:

• A = Maturity amount (Principal + Interest)
• P = Principal (deposit amount)
• r = Annual interest rate (as decimal)
• n = Compounding frequency per year (usually quarterly = 4)
• t = Tenure in years

Example Calculation:

Principal = $10,00,000

Interest Rate = 6.5% per annum

Tenure = 5 years

Compounding = Quarterly (4 times per year)

A = 10,00,000 × (1 + 0.065/4)^(4×5)

A = 10,00,000 × (1.01625)^20

A = 10,00,000 × 1.3804

A = $13,80,400

Interest Earned = $13,80,400 - $10,00,000 = $3,80,400

The calculator supports different tenure types (years, months, days) and automatically calculates the maturity amount with detailed breakdowns.

Using an FD calculator offers several advantages:

Investment Planning: Calculate your FD maturity amount before investing to plan your financial goals. See how much you'll receive at maturity and how much interest you'll earn.

Compare Options: Compare FDs from different banks with varying interest rates and tenures. Find the best FD option that maximizes your returns.

No Login Required: Our FD calculator is completely free and doesn't require any registration. Use it unlimited times to calculate FD returns for different scenarios.

Accurate Calculations: Get precise calculations based on standard banking formulas used by all major banks in India including SBI, HDFC, ICICI, Axis Bank, and others.

Flexible Tenure: Calculate FD returns for any tenure - from 7 days to 10 years. The calculator supports years, months, and days for maximum flexibility.

Visual Breakdown: View charts showing principal vs interest, helping you understand how your FD grows over time.

While our calculator does this automatically, here's how to calculate FD manually:

Step 1: Convert annual rate to decimal

r = Annual Rate ÷ 100

Step 2: Determine compounding frequency

Most banks compound FD interest quarterly (n = 4)

Step 3: Calculate growth factor

Growth Factor = (1 + r/n)^(n×t)

Step 4: Calculate maturity amount

A = P × Growth Factor

Step 5: Calculate interest earned

Interest = A - P

Manual Example:

P = $5,00,000, Rate = 7%, Tenure = 3 years, Compounding = Quarterly

Step 1: r = 7 ÷ 100 = 0.07

Step 2: n = 4 (quarterly)

Step 3: Growth Factor = (1 + 0.07/4)^(4×3) = (1.0175)^12 = 1.2314

Step 4: A = 5,00,000 × 1.2314 = $6,15,700

Step 5: Interest = 6,15,700 - 5,00,000 = $1,15,700

Our calculator automates this calculation and provides detailed breakdowns.
