How is Fixed Deposit Interest Calculated?
There are two methods of calculation of interest on a fixed deposit, viz. Simple Interest and Compound Interest.
What is Simple Interest?
Simple interest is the interest earned on an investment at a predecided rate of interest for a specific period of time. It is calculated by multiplying the principal amount, the rate of interest per annum and the time for which the money is lent in years.
Simple Interest Formula:
SI = P x R x T/ 100
Where,
SI = Simple Interest
P = Principal (amount invested)
R = Rate of Interest (in %)
T = Tenure (time for which deposit is kept in FD account)
For example, if a sum of Rs 10,000 is invested for 3 years at 10% p.a. then at the time of maturity,
SI = 10,000*10*3/100 = Rs 3,000
Maturity Amount = Rs 13,000

How to Use Paisabazaar’s Fixed Deposit Calculator?
To use Paisabazaar Fixed Deposit Calculator, follow these steps:

Enter the deposit amount

Enter the interest rate

Enter the tenure in months or years (the period for which you want FD to be active)

Click the “Calculate” button to get the estimated maturity amount and total interest amount
Note: The FD maturity amount would depend on the deposit amount, FD rates, tenure and type of FD chosen, i.e., cumulative FD and noncumulative FD.
Under noncumulative FD, lenders usually offer a quarterly interest payout option for all tenures wherein the interest is credited quarterly to the current/savings account of the depositor. Depending on the lenders, depositors can also opt for monthly, halfyearly and annual interest payout options of various FD tenures. In the case of the cumulative FD option, the interest component remains invested till the FD maturity.
Monthly interest plans are ideal for retired individuals or for depositors who need a fixed monthly income to meet their daily expenses. The reinvestment or cumulative investment option would help the depositor benefit from the power of compounding, as the interest component remains invested in the FD and starts generating interest income on its own.
What is Compound Interest?
Compound interest is the interest earned on principal as well as interests. It is calculated by multiplying the principal amount with the interest rate raised to the number of periods in years for which the interest will be compounded.
Formula for Compound Interest:
A = P (1+r/n) ^ (n * t)
Where,
A = Maturity Amount
P = Principal amount
r = Rate of Interest (in decimals)
n = number of compounding in a year
t = number of years
For example, if a sum of Rs 10,000 is invested for 3 years at 10% compound interest rate (quarterly compounding), then at the time of maturity,
A= 10,000 {1 + (0.1/4)} ^ (4 * 3)
A = 10,000 (1 + 0.025) ^ (12)
A = 10,000 (1.025) ^ (12) = Rs. 13,449 (approximately)
Compound Interest (CI) Earned over 3 years = Maturity Amount – Principal Amount
CI = 13,449 – 10,000 = Rs. 3,449
