EMI for ₹1 LakhPersonal Loan: 12% for 5 Years

₹33,467 of interest: 33% of the ₹1 Lakh borrowed

You borrow ₹1.00 L and, at 12% over 5 years, repay ₹1.33 L in 60 monthly instalments of ₹2,224. The extra ₹33,467 is interest: roughly 33% of the amount you borrowed. On a long loan the interest can rival the principal itself, which is why the tenure you pick matters as much as the rate.

In year one, ₹11,164 goes to interest; ₹15,529 cuts the principal

In year one, ₹11,164 of your EMIs goes straight to interest and only ₹15,529 chips away at the ₹1.00 L principal. That is because interest is charged on the outstanding balance, which is highest at the start. As the balance falls, each EMI shifts gradually from interest-heavy to principal-heavy: the amortization effect. A prepayment in these early years removes principal before years of interest can accrue on it, so it saves far more than the same amount prepaid later.

Dropping from 5 to 2 years saves ₹20,491 in interest

The monthly EMI looks smaller on a longer tenure, but the total interest climbs steeply. Dropping from 5 years to 2 years on this ₹1 Lakh personal loan raises the EMI from ₹2,224 to ₹4,707, but cuts total interest from ₹33,467 to ₹12,976, a saving of about ₹20,491. Pick the shortest tenure whose EMI stays comfortably under 40% of your monthly income.

Step up the EMI, prepay early, shorten the tenure, compare lenders

• Step up the EMI: raising your EMI by 5–10% each year as income grows can shave years off the loan.
• Prepay early: lump sums from bonuses in the first few years save the most, since interest is front-loaded.
• Shorten the tenure: the EMI difference is often manageable; the interest saving is large.
• Compare lenders: even a 0.25% lower rate on a large, long loan saves a meaningful amount over the full term.
