Compound interest and Simple interest:

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}
