FD Calculator
Calculate Fixed Deposit maturity amount, total interest earned, and effective annual yield for any FD tenure and interest rate.
What is the FD Calculator?
A Fixed Deposit (FD) Calculator helps you determine how much your bank FD will grow to at maturity. Fixed Deposits are one of India's most popular savings instruments โ they are offered by all major banks and NBFCs, provide guaranteed returns with no market risk, and are covered by DICGC insurance up to โน5 lakh per depositor per bank.
This FD Calculator lets you enter any principal amount, annual interest rate, tenure in years, and compounding frequency to instantly see your maturity amount and total interest earned. Banks in India typically compound FD interest quarterly (4 times a year), though some offer monthly or half-yearly compounding.
Why FD Calculators Are Essential
Bank websites and branch staff often quote only the interest rate without clearly showing the actual maturity amount. This calculator removes the ambiguity โ enter your deposit amount and you'll instantly know exactly how much you'll receive at maturity.
The calculator is also useful for comparing FD offers across different banks. A difference of 0.25% in interest rate on a โน10 lakh FD for 5 years translates to over โน13,000 in additional returns โ knowing this helps you choose the better bank.
Types of FDs
Regular FDs hold your money for the chosen tenure with a penalty for premature withdrawal. Tax-Saving FDs (5-year lock-in) offer Section 80C deductions up to โน1.5 lakh. Senior Citizen FDs typically offer 0.25โ0.50% higher interest rates for depositors aged 60 and above. Cumulative FDs reinvest the interest, while Non-Cumulative FDs pay interest at regular intervals (monthly, quarterly, or annually).
FD vs Other Investments
FDs offer safety and guaranteed returns but typically yield less than equity mutual funds over the long term. For conservative investors, short-term savers, and emergency fund holders, FDs remain an excellent choice. This calculator helps you see the exact numbers so you can make an informed choice.
How Does the FD Calculator Work?
1. Enter Principal Amount: Type the amount you want to deposit in your Fixed Deposit.
2. Enter Interest Rate: Input the annual interest rate offered by your bank. Check your bank's latest FD rates online or at a branch.
3. Enter Tenure: Select or type the FD duration in years. Common options are 1, 2, 3, or 5 years.
4. Select Compounding Frequency: Most Indian bank FDs compound quarterly. Choose the appropriate option.
5. View Results: The calculator shows your maturity amount, total interest earned, and effective annual yield.
Formula & Calculation Method
FD Maturity Amount = P ร (1 + r/n)^(nรt)
Where:
- P = Principal (deposit amount)
- r = Annual interest rate รท 100
- n = Number of times interest is compounded per year (1=annual, 2=half-yearly, 4=quarterly, 12=monthly)
- t = Tenure in years
Effective Annual Rate (EAR) = (1 + r/n)^n โ 1
Example: โน1,00,000 at 7% per annum, quarterly compounding, 3 years โ Maturity = 1,00,000 ร (1 + 0.07/4)^(4ร3) = 1,00,000 ร (1.0175)^12 โ โน1,23,144. Total interest = โน23,144.
