Loan calculators

Which calculator you need

If you simply want to know the monthly outgo on a proposed loan, start with the EMI calculator that matches your loan type. Home, car, bike, and personal loan EMIs are all computed with the same formula, but the typical rates and tenures differ enormously, so each calculator starts with sensible defaults for that product. A home loan might run 20 years at 8.5 per cent, while a personal loan is more likely to be 4 years at 14 per cent.

If your question is how much you can borrow rather than what a known amount costs, use the eligibility calculator. It works backwards from your income and existing obligations using the FOIR approach that lenders apply internally.

If you already have a loan running and have come into some money, the prepayment calculator shows whether putting that money into the loan beats leaving it invested. The amortization schedule and the interest versus principal tool are for understanding an existing loan in detail, month by month.

Why the early years feel like you are getting nowhere

Every EMI is split between interest and principal, but the split is heavily weighted toward interest at the start. Interest each month is charged on the outstanding balance, which is at its largest in month one. On a 20-year home loan at 8.5 per cent, roughly 81 per cent of your first EMI goes to interest and only 19 per cent reduces the loan. The crossover point, where principal finally exceeds interest within a single instalment, typically arrives somewhere past the halfway mark of the tenure.

This is why a loan you have paid for five years often shows a balance barely lower than what you borrowed, and it is the single most common surprise for first-time borrowers. The amortization schedule makes the pattern visible rather than theoretical.

Tenure is the lever that matters most

Lengthening the tenure reduces the EMI, which is why lenders offer it so readily, but it increases total interest sharply because the balance stays high for longer. Shortening the tenure does the opposite. Running the same principal through the EMI calculator at two different tenures is usually more revealing than shopping for a slightly better rate.

A practical approach is to pick the shortest tenure whose EMI you can comfortably sustain in a bad month, not the shortest tenure you can manage in a good one. An EMI that forces you to borrow elsewhere during a rough quarter has defeated its own purpose.

Costs that sit outside the EMI

The EMI covers interest and principal only. Processing fees of roughly 0.5 to 2 per cent of the loan, legal and technical valuation charges on secured loans, stamp duty on the loan agreement in some states, and mandatory or strongly encouraged insurance all come out of your pocket separately, usually upfront. On a vehicle loan, registration and insurance are additional again.

When comparing two offers, add these one-time costs to the total interest from the calculator. A lender quoting a marginally lower rate with a two per cent processing fee can easily be more expensive overall than one quoting slightly higher with no fee.

Floating rates change the answer over time

Most Indian home loans are floating rate, benchmarked to the repo rate under the external benchmark regime. When the benchmark moves, lenders usually hold your EMI steady and adjust the tenure instead, which is less visible but materially changes what you pay. A one percentage point rise on a long home loan can add years to the term.

Every figure these calculators produce assumes the rate you enter holds for the whole tenure. Treat the output as a snapshot under current conditions, and re-run it whenever your rate is reset.
