Taking out a home loan, car loan, or personal credit line involves a commitment to monthly installments, known as EMIs. Understanding how EMIs are structured helps you budget effectively and save on interest.
The EMI Mathematical Formula
The mathematical equation for calculating EMIs is:
EMI = [P x R x (1+R)^N] / [((1+R)^N) - 1]
Where P is the Principal, R is the monthly interest rate, and N is the number of monthly payments.
How Compounding Multiplies Interest
In early tenures, a large portion of your monthly EMI goes toward paying off the interest component, rather than the principal loan amount. By making prepayments early on, you directly reduce the principal baseline and save significantly on overall interest cost.
