How to calculate interest rate on a loan, The amount that a depositor is expected to earn on a principal amount at a predetermined rate, or the amount that a borrower is required to pay, is referred to as "interest on loan." This amount is known as the rate of interest, and the formula for interest can be obtained by multiplying the interest rate by the principal amount that is still owed and the length of the loan or deposit.

## The Formula for Interest Calculation

The formula to calculate interest on a loan is:

Interest on Loan = P * r * t,

Whereas,

P = Outstanding principal amount

r = Rate of interest

t = Tenure of loan/deposit

When interest is paid on a periodic basis (monthly, quarterly, etc.), the interest payment equation may be found by multiplying the principal amount owed by the interest rate and then dividing the result by the total number of periodic payments made in a year.

In mathematical terms, the interest can be calculated using the below formula.

Interest on Loan = P * r / N

Whereas,

P = Outstanding principal amount

r = Rate of interest

N = No. of periodic payments per year

### Step-wise procedure to calculate interest on a loan

• Lastly, as seen below, the interest may be calculated by multiplying the principal amount that is still owed, the interest rate, and the loan or deposit's term.
