How to calculate PNB FD Interest?

PNB FD interest rates is calculated using 2 methods, firstly simple interest and secondly compound interest. The selection of which method depends on the tenure of the fixed deposit. Under both methods, the interest amount depends on multiple factors like interest rate, tenure, payout frequency, and compounding frequency.

Simple Interest on FD 

Simple interest is the interest earned on the investment amount for a given period of time at a predetermined interest rate. In case the tenure of PNB FD is less than 181 days or 6 months then simple interest is applicable. 

Simple Interest Formula

Interest = (P * R * T)/ 100


P = Principal amount of fixed deposit investment

R = Rate of FD Interest (%)

T = Tenure of FD investment 

Let us understand the calculation with the help of an example

Mr. Amar invests Rs 400,000 in PNB fixed deposit on 1st March 2021. The investment is for 60 days at an interest rate of 8% per annum. 


P (the investment amount) = Rs 4,00,000

R (rate of interest) = 8% per annum

T (tenure) = 60 days

Simple interest = (P * R * T)/ 100

                  = (Rs 4,00,000 * 8 * 60 days) / 100 * 365 days

                         = Rs 5,260

Maturity amount on FD = Principal Investment Amount + Interest Earned

                                      = Rs 4,00,000 + Rs 5,260

                                      = Rs 4,05,260

Compound Interest on FD

Compound interest is the interest earned on the principal amount invested and the interest earned. The interest rate is raised to the number of periods (years) for which the interest will be compounded and multiplied to the principal amount invested. 

In case the tenure of the PNB fixed deposit is more than 181 days or 6 months then compound interest is applicable.  Under compound interest, the interest earned in the previous period is added to the opening balance of the current period. Hence, a higher compounding frequency, lower payout, and higher tenure lead to higher interest amounts. Tenure is the most important influencing factor in calculating the compound interest. We can say that an FD with compounding interest is a better investment option than an FD with simple interest. 

Compound Interest Formula

A = P (1+r/n) ^ (n * t)

A = Maturity Amount

P = Principal amount invested

r = Rate of Interest (in decimals)

n = number of compounding in a year

t = number of years


Mr. Ajay invests Rs 80,000 for a period of 4 years at an interest rate of 7% per annum compounded quarterly. 


Principal amount of investment = Rs 80,000

Interest Rate = 7% per annum compounded quarterly

Number of compounding in a year = 4 (once every 3 months)

Number of years of investment is 4 years

A = 80,000 (1+0.07/4) ^ (4*4)

A = Rs 85,748

Interest amount = Rs 85,748 – Rs 80,000 = Rs 5,748
