What Is Fixed Deposit Calculator?
An FD Calculator is a free online tool that instantly computes the maturity amount and interest earned on a fixed deposit, based on your principal, tenure, interest rate, and compounding frequency. It removes manual calculation errors and helps you compare FD options across banks and NBFCs before investing. Senior citizens can also account for the additional 0.25%–0.75% interest rate advantage most banks offer.
How Fixed Deposit Calculator Helps You
Before booking a Fixed Deposit, it is essential to compare offers and understand what your money will actually earn — including post-tax income. The FD calculator makes this instant.
- Know the exact maturity amount and total interest earned before booking any FD
- Compare cumulative (reinvested) vs non-cumulative (monthly payout) FD returns side-by-side
- Factor in TDS deduction for accurate post-tax income planning
- Evaluate the senior citizen rate advantage — see the rupee difference at +0.50%
- Plan an FD laddering strategy by estimating returns at staggered tenures for better liquidity
How Does Fixed Deposit Calculator Work?
Most Indian bank FDs use quarterly compounding for cumulative deposits. The formula is: A = P × (1 + r/4)^(4 × n), where P is the principal, r is the annual interest rate as a decimal, and n is the tenure in years. For simple interest (non-cumulative FDs or tenures under 6 months): SI = P × r × t / 100. For example, ₹5 lakhs at 7% for 3 years with quarterly compounding grows to approximately ₹6.17 lakhs — earning ₹1.17 lakhs in interest. The calculator handles both cumulative and simple interest modes automatically.

Frequently Asked Questions
Yes. FD interest is fully taxable as "Income from Other Sources" at your income tax slab rate. Banks deduct TDS at 10% if interest exceeds ₹40,000 per financial year (₹50,000 for senior citizens). Submit Form 15G (below 60 yrs) or 15H (60+ yrs) to avoid TDS if your total income is below the taxable limit.
In a cumulative FD, interest is compounded and paid at maturity — giving you a higher total return. In a non-cumulative FD, interest is paid out monthly, quarterly, or annually — giving you regular income. Cumulative FDs are better for long-term wealth building; non-cumulative FDs suit retirees needing regular cash flow.
Premature withdrawal typically incurs a penalty of 0.5%–1% on the contracted interest rate for the period held. The maturity amount shown in this calculator assumes full-tenure FD. Breaking early reduces your effective return. Always check your bank's premature withdrawal penalty before booking.
FD laddering means splitting a large sum across multiple FDs with staggered maturities (e.g., ₹2L each for 1Y, 2Y, 3Y, 4Y, 5Y). This gives you annual liquidity, lets you reinvest at prevailing rates as each FD matures, and avoids being fully locked in at one rate. It typically earns more than a single large FD over the same period.
DICGC insurance (up to ₹5 lakh) covers only scheduled commercial banks — not NBFCs. NBFC FDs offer higher rates but carry higher risk. Before investing in an NBFC FD, check its credit rating (prefer CRISIL or ICRA AAA-rated NBFCs) and limit exposure to a small portion of your overall FD portfolio.
