How does a personal loan EMI work?
A personal loan is unsecured — there is no house or car pledged behind it — so the lender is taking on more risk and prices that risk into a higher rate than a home or car loan. Tenures are short, commonly one to five years, and the whole amount lands in your account as cash to use for a wedding, a medical bill, a renovation or consolidating costlier dues.
You repay through a fixed monthly instalment built on the reducing-balance method, so interest applies only to the sum still owed. A ₹5,00,000 loan at 11% over five years, for example, settles at about ₹10,871 a month and carries roughly ₹1,52,000 of interest across the term. Do watch for the one-time processing fee, typically 1-3% of the amount, which is deducted up front and lifts your effective cost above the headline rate.
Why a “flat 10%” is really about 18%
The most expensive trap in personal lending is the flat rate. Under a flat quote, interest is charged on the entire original amount for every year of the loan, ignoring the fact that you are steadily paying the balance down. A reducing rate, by contrast, only charges you on what is actually left owing — the honest way to compare loans.
Watch what happens on a ₹1,00,000 loan quoted at a “flat 10%” for one year. The interest is a flat ₹10,000, the total repayable is ₹1,10,000, and split over twelve months that is an EMI of about ₹9,167. Feed that same instalment back into a reducing-balance sum and it corresponds to an effective rate of nearly 18% — almost double the number on the brochure. Whenever a lender quotes flat, mentally roughly double it to see the true reducing-rate cost before you compare offers.
| Flat rate advertised | 10% p.a. |
| Flat interest charged | ₹10,000 |
| EMI (₹1,10,000 ÷ 12) | ₹9,167 |
| True reducing-rate cost | ≈ 18% p.a. |
How much can you borrow? FOIR and your income
Lenders cap how much of your monthly income can go towards loan repayments, a limit known as FOIR — the Fixed Obligation to Income Ratio. Most set it somewhere between 40% and 55% of your net take-home pay, counting every existing EMI plus the new one you are asking for. The room left inside that ceiling is what decides your sanction, not just the salary figure.
Suppose you take home ₹80,000 a month and already pay ₹10,000 towards other EMIs. At a 50% FOIR the lender wants total instalments under ₹40,000, leaving about ₹30,000 of headroom for a new loan. At 11% over five years that space supports a loan of roughly ₹13,80,000. Clearing a card balance or an old EMI before you apply frees up FOIR and can meaningfully lift the amount on offer.
Ways to lower your personal loan EMI
The gentlest lever is tenure: stretching a ₹5,00,000 loan at 11% from five years to seven drops the EMI from about ₹10,871 to roughly ₹8,561, though you pay more interest overall, so treat it as breathing room rather than a saving. The sharper lever is the rate itself — a clean credit history matters. On that same loan, a 13% rate instead of 11% costs around ₹11,377 a month versus ₹10,871, so every point you shave off is real money back.
Beyond those, borrow only what you truly need rather than the maximum offered, use part-prepayment whenever spare cash appears to knock down the principal, and consider a balance transfer to a cheaper lender if you are stuck on a high legacy rate. Consolidating several small high-rate dues into one lower-rate personal loan can also bring the combined outgo down.
