EMI for ₹15 LakhPersonal Loan: 12% for 5 Years

₹5,02,000 of interest: 33% of the ₹15 Lakh borrowed

You borrow ₹15.00 L and, at 12% over 5 years, repay ₹20.02 L in 60 monthly instalments of ₹33,367. The extra ₹5.02 L 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, ₹1,67,465 goes to interest; ₹2,32,935 cuts the principal

In year one, ₹1.67 L of your EMIs goes straight to interest and only ₹2.33 L chips away at the ₹15.00 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 ₹3,07,355 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 ₹15 Lakh personal loan raises the EMI from ₹33,367 to ₹70,610, but cuts total interest from ₹5.02 L to ₹1.95 L, a saving of about ₹3.07 L. 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.
