Understanding Interest Rates better

Few types of Interest rates used  are mentioned below:

  • Simple Interest

It is the simplest type of Interest with a quick and easy method of calculating the interest charged on a loan, its calculation is only based on outstanding principle balance. The simple interest does not rely and increase the loan balance which means the interest to be paid for each monthly payment cannot increase.

Simple Interest=P×I×N

where: P=principle

I=daily interest rate

N=number of days between payments

  • Compound Interest:

Is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.( Source Wikipedia) 

s A = P (1 + r/n) ^ nt

For this formula, P is the principal amount, r is the rate of interest per annum, n denotes the number of times in a year the interest gets compounded, and t denotes the number of years.

John borrowing $100 from the bank for two years at a 10% interest rate. For the first year, we calculate interest as usual.

$100 × 10% = $10

This interest is added to the principal, and the sum becomes John’s required repayment to the bank for that present time. 

$100 + $10 = $110

However, the year ends, and in comes another period. For compounding interest, rather than the original amount, the principal + any interest accumulated since, is used. In John’s case:

$110 × 10% = $11

John’s interest charge at the end of year 2 is $11. This is added to what is owed after year 1:

$110 + $11 = $121

When the loan ends, the bank collects $121 from John instead of $120 if it were calculated using simple interest instead. This is because interest is also earned on interest.

The more frequently interest is compounded within a time period, the higher the interest will be earned on an original principal. The following is a graph from Wikipedia showing just that, a $1,000 investment at various compounding frequencies earning 20% interest.

Understanding EMIs:

fixed payment amount made by a borrower to a lender at a specified date each calendar month. Equated monthly instalments are used to pay off both interest and principal each month so that over a specified number of years, the loan is paid off in full

The formula we use to calculate Interest rates and total amount payable in EMIs is

E = P * r * (1+r)^n / ((1+r)^n-1)

In the equation, the following are represented –

EEMI repayable
PPrincipal loan amount
R/rRate of interest applicable
N/nTenure in years

Principal loan amount is the amount borrowed and must be paid back. Applicable Interest Rate means an annual rate equal to 12% prior to any Event of Default, and 24% after the occurrence of any Event of Default, calculated on the basis of a 365-day year and computed using the actual number of days elapsed since the Issue Date or the date on which Interest was most recently paid.

Calculating manually with the use of these formulas at times turns out to be difficult and has more chances of error and mistakes for someone from a non-financial background. To bring ease to this the Interest Rate calculator is designed with simple entries all you have to do is put the value of loan amount, interest rate, and loan tenure. The Interest Rate Calculator will instantly calculate and provide you with the value without any error.
