Everything you need to know about loans, EMI, interest rates, prepayment strategies, and how to choose the best loan offer. Save lakhs with smart borrowing.
EMI (Equated Monthly Installment) is the fixed amount you pay every month to repay a loan. Every EMI has two parts:
Interest component: The cost of borrowing, charged on the outstanding balance.
Principal component: The actual loan repayment that reduces your outstanding balance.
Why early payments are mostly interest
In a ₹50L home loan at 8.5% for 20 years (EMI: ₹43,391), your first month's EMI is split: ₹35,417 goes to interest (82%) and only ₹7,974 to principal (18%). By month 120, it's roughly 57/43. In the final month, over 99% goes to principal.
This is why prepaying in the early years saves the most money — each rupee of extra principal payment eliminates years of future interest. Try the EMI Calculator to see this amortization breakdown for your loan.
The EMI formula
EMI = P × r × (1+r)n / [(1+r)n − 1]
Where P = loan amount, r = monthly interest rate, n = total months. You don't need to memorize this — our EMI Calculator does it instantly with a full amortization schedule.

Key insight: Home loans are the cheapest because they're secured by property. A ₹5L need funded by a personal loan at 14% costs ₹17,089/month for 3 years (total interest: ₹1,15,197). The same ₹5L as a home loan top-up at 9% costs ₹6,334/month for 10 years (total interest: ₹2,60,055). Lower EMI but higher total cost — choose tenure wisely!
A home loan is likely the largest financial commitment of your life. Here's everything you should know before signing.
How much home can you afford?
Banks typically lend 75-90% of a property's value (called LTV ratio); RBI caps it at 75% for loans above ₹75 lakh. For a ₹1 Cr home, you'll need at least ₹25L as down payment plus ₹7-8L for stamp duty, registration, and other charges.
Thumb rule: Your home loan EMI should not exceed 35-40% of your take-home salary. If you earn ₹1L/month, keep EMI under ₹40K. Use our Mortgage Calculator to find a comfortable loan amount.
Fixed vs floating rate
Floating rate (most common): Linked to repo rate. Changes when RBI changes rates. Currently offers lower starting rates. No prepayment penalty.
Fixed rate: Stays constant for the entire tenure (or initial 2-5 years). Usually 1-2% higher. Prepayment penalty may apply.
For long tenures (15-30 years), floating rate usually saves more historically, and you can always prepay without penalty.
The total cost shock
A ₹50L home loan at 8.5% for 20 years has an EMI of ₹43,391. But the total repayment is ₹1.04 Cr — you pay more in interest (₹54L) than the loan itself. Reducing tenure to 15 years increases EMI to ₹49,237 but saves ₹15L in interest.
Prepayment is the single most powerful tool to reduce your loan cost. Even modest extra payments create massive savings due to the way compound interest works on loans.

Best prepayment strategies
Use annual bonuses: Dedicate 50% of every bonus to loan prepayment. One extra EMI per year is effortless.
Increase EMI with salary hikes: Got a 10% raise? Increase your EMI by 5-7%. You won't feel the difference, but your loan will finish years early.
Reduce tenure, not EMI: When prepaying, choose "reduce tenure" over "reduce EMI" for maximum interest savings.
Front-load prepayments: Prepaying ₹1L in year 2 saves far more than the same ₹1L in year 15, because early principal reduction eliminates more future interest.
Certain loans offer significant tax deductions that effectively reduce your cost of borrowing:
Home loan
Section 80C: Principal repayment up to ₹1.5 lakh/year (shared with PPF, ELSS, etc.)
Section 24(b): Interest payment up to ₹2 lakh/year for self-occupied property
Section 80EEA: Additional ₹1.5 lakh interest deduction for affordable housing, only for loans sanctioned between April 2019 and March 2022 (subject to conditions)
These deductions apply only under the old tax regime. At the 30% slab, Section 24(b) and 80C together can save up to about ₹1.1 lakh in tax a year (about ₹1.56 lakh for loans that also qualify for 80EEA), but the old regime only beats the new one if your total deductions are large enough.

Education loan
Section 80E: Entire interest amount (no cap) deductible for 8 years from start of repayment.
No tax benefits
Personal loans and car loans offer no direct tax deductions. This makes them the most expensive in real terms. Avoid personal loans if a home loan top-up is available at lower rates.
Choosing the longest tenure for lowest EMI: A ₹30L loan at 9% for 20 years costs ₹26,992/month but ₹34.8L total interest. For 10 years: ₹38,003/month but only ₹15.6L interest. You save ₹19.2 lakh by choosing shorter tenure.
Ignoring processing fees in your comparison: A bank offering 8.4% with 1% processing fee may cost more than 8.5% with zero processing fee.
Not checking your credit report first: Get your free CIBIL report before applying. Fix errors (common!) to ensure you get the best rate.
Stretching beyond your budget: Banks may approve ₹80L, but that doesn't mean you should take it. Leave room for other goals and emergencies.
Skipping loan insurance: For home loans, a simple term plan ensures your family isn't burdened if something happens. The cost is trivial compared to the risk.
Not reading prepayment clauses: Some fixed-rate loans charge 2-5% prepayment penalty. Always verify before signing.
Multiple loan applications simultaneously: Each application triggers a "hard inquiry" that lowers your credit score by 5-10 points. Apply to 2-3 banks maximum.
Neglecting balance transfer opportunities: If your current rate is significantly higher than market rates, transferring saves money. Banks charge 0.5-1% transfer fee, which typically pays for itself within months.
