Key points
- The EMI depends on principal, monthly rate and tenure; early instalments are mostly interest.
- A longer tenure lowers the EMI but raises the total interest paid.
- Banks usually absorb rate rises by extending tenure, so check your schedule after each reset.
- The RBI bars prepayment and foreclosure charges on floating-rate home loans to individuals.
- Prepaying early saves the most; say in writing whether you want a shorter tenure or lower EMI.
How the EMI is calculated
Home loan EMI calculation starts from the fact that an equated monthly instalment is fixed by three inputs: the principal, the monthly interest rate and the number of months. The standard formula is EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1), where r is the annual rate divided by twelve and n is the tenure in months.
Every instalment is part interest and part principal. Early on the interest share dominates; only in the later years does the balance fall quickly. This is arithmetic, not a bank policy, and it is the reason a loan feels like it is not moving for the first few years.
What tenure does
A longer tenure lowers the monthly instalment and raises the total interest paid, because the balance sits outstanding for longer. A shorter tenure does the opposite.
The useful test is not the EMI you can just about afford, but the EMI you can still pay in a bad year. Lenders generally look for the instalment to sit within a comfortable share of net monthly income, counting your other obligations.
Floating rates and resets
Most Indian home loans for individuals are floating and are linked to an external benchmark, usually the policy repo rate, under the Reserve Bank of India's external benchmark lending rate framework. When the benchmark moves, your rate resets at the interval stated in your sanction letter.
Banks normally absorb a rate rise by extending the tenure rather than raising the EMI. That keeps your monthly outgo steady and quietly increases the interest you will pay. Check your amortisation statement after every reset and ask for the EMI to be raised instead if you can afford it.
Prepayment
The Reserve Bank has directed that banks and housing finance companies must not charge foreclosure or prepayment penalties on floating-rate home loans taken by individual borrowers. Fixed-rate loans can still carry a charge, so read the sanction letter.
A prepayment reduces the outstanding principal, so all future interest is computed on a smaller balance. Prepaying early in the tenure saves far more than the same amount prepaid late, because more interest remains to be avoided.
You can ask for the saving to be taken as a shorter tenure or a lower EMI. Shorter tenure saves more interest; a lower EMI improves monthly cash flow. Say which you want in writing — most lenders default to reducing the tenure.
Before you sign
Ask for the full amortisation schedule, the reset frequency, the spread over the benchmark, the processing fee and the conditions for switching to a lower spread later.
Compare the annual percentage cost including fees rather than the headline rate, and keep a buffer of a few instalments in reserve before you commit to the largest loan you are offered.
Common questions
Does prepaying reduce my EMI or my tenure?
Either, but you have to choose. Most lenders shorten the tenure by default; ask in writing if you would rather have a lower instalment.
Can a bank charge me for closing a home loan early?
Not on a floating-rate home loan to an individual borrower — the Reserve Bank of India prohibits foreclosure charges there. Fixed-rate loans may carry a charge, so check your sanction letter.
Is a longer tenure always worse?
It costs more interest, but a longer tenure that keeps the instalment safely affordable is better than a short one you cannot sustain. You can always prepay later.
