Complete Guide On How To Calculate FD Interest Rate?

Save & Invest

FD is a type of savings that you can do by putting a fixed amount safe for a particular tenure. The tenure of an FD can be from a few days to up to 10 years. The interest rate of the fixed deposit remains fixed at the time when you are opening it. You can use the FD interest calculator to calculate interest income and maturity amounts.

What is a Fixed Deposit? 

A fixed deposit is a term deposit where you invest your money and after a fixed tenure you can take your principal amount back along with the fixed interest rate. When you invest in fixed deposits you get an interest rate better than the other options such as a savings account.

If there is an emergency you are allowed to break your FD by paying a certain amount as a penalty, which is not that high. You can choose to have the interest credited to your account at regular intervals or once the deposit gets matured. You will receive the maturity amount at the end of the FD term if you invest money in an FD plan.

FD Interest Calculator helps in calculating the exact amount that you will receive once your FD gets mature.

Fixed deposits are available in two types. 

  • Cumulative Fixed Deposit (FD): A cumulative fixed deposit pays compounded interest annually or quarterly. In general, cumulative fixed deposits pay a greater interest rate. 
  • Non-cumulative FD: A non-cumulative fixed deposit pays interest on a monthly, quarterly, half-yearly, or annual basis, depending on the investor’s preference. Non-cumulative FDs have lower interest rates than cumulative FDs. It is suitable for people who desire a consistent income from their investments. 

What is an FD Monthly Payout?

The FD monthly payout means that you opt to take the interest every month on your FD, instead of taking it at the time of maturity. Comparatively the interest rate of the amount taken monthly is less than the ones received through other frequencies. Monthly payouts are preferred by those who want who look for steady and fixed monthly incomes.

It is vital to remember that the maturity amount changes depending on the type of deposit, interest rate, FD period, deposit amount, and customer type. Choose a customer type. Understanding that each choice will have a different interest rate is vital. Select the fixed deposit type. Enter the amount of your FD and choose the period of your fixed deposit arrangement.

The calculating formula is as follows: A = P (1+r/4/100) ^ (4n) (4n) Or, A = P (1 + r/25) 4*n A = the maturity amount in this case. P = Principal or deposited amount n = compounded interest frequency. The FD calculator allows you to arrange your investment with ease. Assume you want to put Rs. 1,00,00 in a five-year fixed deposit at an interest rate of 10%. A is your maturity amount now = 1,00,000 (1+(10/25)= 140000 where P denotes the Principal, n the term, and r the interest rate.

FD and Taxes

The interest earned on an FD is taxed. The tax on fixed deposits is deducted at the source and ranges from 0% to 30%. The basis of the TDS deduction is the investor’s income tax bracket. If you earn more than Rs. 10,000 in interest in a year, the bank will deduct around 10% TDS. If you do not provide your PAN number, you can get a deduction on TDS of 20%.

You can, however, claim the deducted TDS if your total income is less than the 10% tax slab.

If you are not in a tax bracket, you can avoid the tax deduction by submitting Form 15G to your bank. Senior citizens can prevent deductions tax by submitting Form 15H. If you fall into a higher tax category (20-30%), you will be required to pay additional tax on top of the TDS deducted.

Factors that affect FD Rates

Let’s have a look at the factors that impact the rates of FD:

  • The more the amount invested, the greater the interest given out. In general, you can get more effective interest rates if the deposit is for a more extended period. 
  • You can receive a greater interest rate if you choose a cumulative fixed deposit program. 
  • Senior citizens get preferential interest rates. 
  • If you are considering investing in one of the fixed deposit programs, the FD calculator will be helpful.
