FD Calculator

Accurate Online Fixed Deposit (FD) Calculator

Our FD Calculator is a premium, professional-grade financial utility designed to compute post-tax and pre-tax maturity values for your term deposits. Fixed Deposits (FDs) remain one of the most reliable, risk-free investment options in India, offering guaranteed returns with flexible investment tenures ranging from 7 days up to 10 years.

How Fixed Deposit Interest Compounds

In most Indian commercial banks (such as State Bank of India, HDFC Bank, ICICI Bank, Axis Bank, and Bank of Baroda), FD interest compounds on a quarterly basis (every 3 months). The mathematical compounding formula used to calculate your total maturity value is:

A = P × (1 + r / n)^(n × t)

Where:

• A: Total Maturity Amount (Principal + Interest Earned)
• P: Principal Investment Amount (Initial Deposit)
• r: Annual Rate of Interest (expressed as a decimal, e.g., 7% = 0.07)
• n: Number of compounding periods per year (n = 4 for quarterly compounding)
• t: Total tenure in years

Taxation on Fixed Deposit Interest (TDS & Income Tax Rules)

Interest earned on Fixed Deposits is fully taxable under the head "Income from Other Sources" according to your applicable income tax slab rates:

• TDS Limit for Regular Citizens: Banks deduct 10% TDS (Tax Deducted at Source) if your annual interest income across all FD accounts in a bank exceeds ₹40,000 in a financial year (10% with PAN, 20% without PAN).
• TDS Limit for Senior Citizens (Section 80TTB): For senior citizens (age 60+), the TDS threshold limit is elevated to ₹50,000 per financial year.
• Form 15G / Form 15H Exemption: If your total taxable annual income is below the basic exemption slab, submit Form 15G (for individuals below 60) or Form 15H (for senior citizens) at the start of the financial year to prevent TDS deduction by the bank.

Comparing Top Bank FD Rates in India

FD interest rates vary based on tenure, deposit amount, and investor category (senior citizens typically receive an additional interest rate premium of 0.50% p.a.). Using an online FD calculator before booking your deposit helps you lock in optimal interest rates across short-term, medium-term, and 5-year tax-saving FDs under Section 80C.
