Fixed deposit is a financial instrument where depositors invest a lump sum in a bank where it stays invested for a finite period. In return, you will earn a pre-determined interest on your deposits, which is generally higher than a savings account
Crores of Indians are benefiting out of this scheme through various banks. In fact, the government was able to bring a vast section of people under banking after luring them with lucrative FDs. It is the most preferred method of investment
A Fixed deposit calculator is a handy tool which helps you calculate the estimated value of your investment in FD based on the amount you deposit, interest rate, and tenure
The Fixed Deposit Calculator uses a simple formula to calculate the maturity amount. It takes into account the principal amount, interest rate, and tenure of the FD. The formula used can be calculated into two ways for simple interest FD and Compound Interest FD4
For Simple interest FD
M = P + (P x r x t/100)
where –
Note: Simple interest FD is applicable only on deposits that lasts for a few days
For Compound Interest FD (fairly common)
M= P + P {(1 + r/100) t – 1}
P – Principal
r – rate of interest
t – tenure in years
Example:
For example, you make an investment of 5 Lakhs at an interest rate of 9.1% for 5 years then your return would be 500000+ 500000(1+8.1/100)5-1 which is ₹7,84,079
1. Can I use the calculator for different interest rates offered by different banks?
The formula is same for all the banks. So, you can use the calculator for different interest rates
2. Does the calculator consider compounding interest?
Yes, most FD calculators automatically factor in compounding interest for accurate calculations.
3. What is the interest on 5 lakh FD for 1 year?
The interest rate depends on various banks and it varies from bank to bank
4. What happens if I break the FD before maturity?
The calculator doesn’t take into account pre-mature withdrawal penalties, so, you cannot predict the accurate amount
5. Does the calculator consider taxes on FD interest?
No, the calculator won’t take any taxes into consideration
