## Example of Principal Amount

We have described two examples of the principal amount below so that you can comprehend the concept well.

Suppose you deposit ₹ 70,000 in your interest-bearing savings account. After seven years, it becomes 75,000. The initial invested amount, i.e. ₹ 70,000, will be your principal amount, and the remaining ₹ 5,000 is the interest earned.

Now, you might be wondering – what is the principal amount of a loan?

In the case of loans, the principal amount refers to the actual amount you borrowed from the lender and the remaining amount after you have repaid a part of it.

Let us consider an example. Suppose you borrowed a home loan of ₹ 25 lakh, and you have already paid ₹ 10 lakh. The principal amount, in the beginning, was ₹ 25 lakh. However, now it is ₹ 15 lakh, as you have paid the rest.

## Principal Amount Amortisation

When borrowers take loans, they usually make monthly payments to the lender. This is the most common use of amortisation. A fraction of the payment consists of the interest on the loan, while the remaining payment reduces the principal amount owed.

On the other hand, the interest is calculated on the current amount owed. Therefore, it becomes progressively smaller as the principal decreases. You can look at the same on the principal amount amortisation table below.

Here, we have considered a total loan amount (principal amount) of ₹ 20,000 for a tenure of 10 years. The interest on the loan is 6%.

 Beginning Balance Interest Principal Ending Balance 1 \$20,000.00 \$1,159.05 \$1,505.43 \$18,494.56 2 \$18,494.56 \$1,066.19 1,598.29 \$16,896.26 3 \$16,896.26 \$967.61 \$1,696.87 \$15,199.38 4 \$15,199.38 \$862.96 \$1,801.52 \$13,397.85 5 \$13,397.85 \$751.82 \$1,912.66 \$11,485.20 6 \$11,485.20 \$633.88 \$2,030.60 \$9,454.58 7 \$9,454.58 \$508.63 \$2,155.85 \$7,298.71 8 \$7,298.71 \$375.65 \$2,288.83 \$5,009.88 9 \$5,009.88 \$234.50 \$2,429.98 \$2,579.88 10 \$2,579.88 \$84.62 \$2,579.86 \$0.00
