How to use this calculator
Each step names a control you will find on screen above.
- Deposit amount
The lump sum you are placing in the FD.
- Interest rate
The annual rate the bank quotes. Senior citizens usually get about 0.5% more, and small finance banks a little more again for the extra risk.
- Tenure
How long the money is locked in, in years. Breaking the FD early forfeits part of the interest.
Worked example: Five years at 7%
A ₹5,00,000 deposit at 7% for five years, compounded quarterly.

Where this is taught
A calculator gives you a number. These explain what the number means and when it misleads you.
- Market Basics12 minBonds and fixed incomeWhy bond prices move opposite to rates, what duration and credit risk actually mean, and how to buy government securities directly in India.
- Market Basics12 minDebt funds: credit risk, duration and the tax changeThe category most investors hold without understanding. Two risks, sixteen sub-categories, and why the 2023 tax change altered where they belong.
- Market Basics11 minBond duration and convexity: how much a bond really movesYou know a bond falls when rates rise — duration tells you by how much. What modified duration measures, why longer and lower-coupon bonds are more sensitive, and what convexity adds.
- Market Basics8 minCredit risk funds: the extra yield that can vanish overnightSome debt funds pay a noticeably higher yield by lending to weaker companies. That extra yield is not free money — it is the fee you are paid for a risk that shows up all at once, and rarely reverses.
- Market Basics8 minDynamic bond funds: betting the manager can read interest ratesMost debt funds are pinned to a fixed slice of the maturity spectrum. A dynamic bond fund is free to roam the whole of it, lengthening or shortening as the manager reads interest rates — which makes your return a bet on how good that reading is.
