What is Simple and Compound Interest

Simple Interest

Simple Interest is calculated on the original principal amount for the entire duration of the loan or investment. The formula for calculating Simple Interest is:

Where:

P = Principal (initial amount of money)
R = Rate of interest per annum
T = Time period (in years)

Compound Interest

Compound interest is calculated on the principal amount and the interest that accumulates over time. This means that the interest earned each period is added to the principal amount, and interest is calculated on this new amount.

Simple & Compound Formula

Compound interest:
Interest = Amount – Principal

If Rs. ‘P’ is invested at a rate of ‘r%’ p.a. compounded annually for ‘t’ years, then the amount received after ‘t’ years will be = P × {1 + (r/100)}^t

If the interest is not compounded annually, then

Effective rate of interest = Actual rate ÷ Number of times the interest is compounded in a year

Effective time period = Actual time period × Number of times the interest is compounded in a year

Simple interest:

If Rs. ‘P’ is invested at simple interest of ‘r%’ p.a. for ‘t’ years, then the amount received after ‘t’ years will be = P + {(P × r × t)/100}

And, the simple interest received = {(P × r × t)/100}

Relationship between simple interest (SI) and compound interest (CI):

When a principal (P) is invested at the rate of ‘r%’ p.a., then

Difference between SI and CI after two years = P × (r/100)²

Difference between SI and CI after three years = P × (r/100)² × {(r/100) + 3}
