An equated monthly instalment is the fixed amount that, at the stated rate and schedule, pays the loan down to exactly zero at the end of 120 months. The closed form is EMI = P × r × (1 + r)ⁿ / ((1 + r)ⁿ − 1), where P is the principal, r is the monthly rate (annual ÷ 12 ÷ 100), and n is the number of instalments. Substituting your numbers — P ≈ ₹7,00,000, r ≈ 0.007083, and n = 120 — lands on the ₹8,679 a month shown above, with ₹3,41,480 of interest over the life of the loan.

The mechanism worth internalising is the reducing balance. Interest each month is charged only on what you still owe, not on the original disbursal. So in month one, interest is calculated on the full ₹7,00,000 and eats a large share of your EMI; by the final year the balance is small, and almost the whole EMI clears principal. This single fact explains most of what follows on this page — why a longer tenure costs so much more interest, why a small rate change compounds, and why prepaying in the early years saves far more than prepaying near the end.

Holding the rate and tenure fixed at 8.5% and 10 years, here is how the EMI and total interest move for a smaller and a larger personal loan than the one you entered:

• Half the size (₹3,50,000): EMI around ₹4,339, total interest near ₹1,70,740.
• Your entered amount (₹7,00,000): EMI about ₹8,679, total interest about ₹3,41,480 — the baseline used throughout this page.
• Half again as large (₹10,50,000): EMI around ₹13,018, total interest near ₹5,12,220.

The EMI scales almost in step with the loan amount, but the interest does not track it perfectly, because compounding on a larger balance behaves a little differently at each EMI level — so re-run the exact figure in the calculator rather than scaling these by hand.

Same rate, different tenures

On a personal loan the tenures are short by design, so the EMI moves sharply between them — pick the shortest term whose EMI you can comfortably carry.

Same tenure, different loan amounts (±15–25%)

Rates move with lender policy and, on floating loans, with the external benchmark they are linked to. Holding your loan amount and tenure fixed, here is roughly how the EMI and total interest shift if your rate were a little below or above 8.5%:

The swing is smaller on a shorter loan, but it is real — and on an unsecured or used-vehicle loan, where the rate depends so heavily on your profile, it is the number most worth negotiating.

Because interest is charged only on the outstanding balance, the same ₹8,679 EMI buys very different amounts of principal reduction depending on where you are in the schedule. Here is roughly how that split looks across your 10-year loan:

In year one, about 55% of every rupee you pay is interest; by year 10, that share has collapsed to 4%. That front-loading is why a rupee of principal repaid in year one avoids years of future interest, while the same rupee repaid near the end has almost none left to avoid — and why refinancing late in a tenure rarely saves as much as borrowers expect.

Shortening the tenure by about 5 years (where the lender allows it at the same rate) moves the EMI from about ₹8,679 to roughly ₹14,362, while cutting total interest. Lengthening it by about 5 years drops the EMI toward ₹8,679 but pushes total interest up. That is the whole EMI-versus-tenure trade-off in one line: a lower monthly number and a higher lifetime cost are two ends of the same lever.

A personal loan and a carried card balance are both unsecured borrowing, but the personal loan’s fixed schedule is usually the cheaper, more disciplined way to clear a known one-time expense.

On an unsecured loan the lender has no collateral to fall back on, so it prices almost entirely on your profile. In rough order of weight:

Exact criteria vary by lender, but most unsecured personal loan applications are judged against a broadly similar checklist:

Meeting the minimums does not guarantee approval or the best rate — treat this as a starting checklist and confirm current criteria with the specific lender you shortlist.

• Identity proof — PAN and Aadhaar (or passport/voter ID as accepted by the lender)
• Address proof — utility bill, passport, or Aadhaar
• Income proof — latest 3 months’ salary slips and Form 16 (salaried), or 2–3 years’ ITRs and computation of income (self-employed)
• Bank statements — usually the last 6 months, showing salary credits or business cash flows
• Passport-size photographs and a duly signed application form

Digital lenders may accept e-KYC and account-aggregator statements in place of physical paperwork — ask upfront so you are not scrambling for documents close to disbursal.

A personal loan used for personal consumption generally carries no income tax deduction. Narrow exceptions exist — interest may be deductible where the loan is demonstrably used for home renovation, a business purpose, or certain higher-education structures — but each needs clear documentation linking the borrowing to the qualifying use. If a tax benefit is part of why the loan looks worthwhile, confirm the specific provision with a chartered accountant before borrowing; otherwise budget for the full EMI as a post-tax outflow with nothing offsetting it.

• Financing a lifestyle expense you could have saved toward in a few months — every rupee borrowed unsecured costs more than the secured alternative.
• Chasing the lowest advertised rate while ignoring the processing fee and any bundled protection plan — the effective cost of an unsecured loan is often driven as much by fees as by rate.
• Taking a top-up or second personal loan before the first is closed, which stacks your FOIR and can quietly block your next, more important loan.
• Not reading the foreclosure clause — some lenders levy a meaningful charge if you prepay in the first 6–12 months.
• Accepting the first pre-approved in-app offer without checking whether a slightly longer application elsewhere lands a materially better rate.

• Treat the EMI-to-income guideline (rules like “keep EMIs under 40% of take-home”) as a ceiling, not a target — leaving headroom lets you save, stay insured, and absorb a rate reset without renegotiating your whole budget.
• Ask the lender for the full amortization schedule, not just the EMI figure, so you can see month by month how much of each payment clears principal — it makes any future prepayment or refinance decision far easier to reason about.
• Re-run this calculator whenever your income, the quoted rate, or the loan amount changes — small edits move the EMI and total interest more than people expect, and a five-minute recheck beats an unpleasant surprise after signing.
• If your income varies month to month — freelance, commission, or business — size the EMI to your weakest realistic month, not your average or your best one.
• Compare lenders on the total cost of credit — rate plus processing fee plus any bundled insurance or protection plan — rather than the headline monthly figure, which is the easiest number to make look attractive.
