Loan Comparison Calculator
Compare two loans side by side to find the cheaper option - total interest, EMI, and total cost.
⚖️ What is a Loan Comparison Calculator?
A loan comparison calculator lets you evaluate two loan offers side by side - comparing monthly EMIs, total interest paid, and the complete cost of borrowing. It helps you make an informed decision when you have multiple loan options, such as offers from different banks, or when you're deciding between a shorter tenure with a higher EMI versus a longer tenure with a lower EMI.
The true cost of a loan is not just the interest rate - it is the total amount you will repay over the entire tenure. A loan at 8.5% for 20 years and a loan at 9.0% for 15 years can look similar on the surface, but the total interest paid can differ by lakhs of rupees. This calculator makes that difference explicit so you can choose with confidence.
In India, most banks and NBFCs calculate EMI on a reducing balance basis - meaning interest is charged only on the outstanding principal, not the original loan amount. As you repay each EMI (which contains both interest and principal), the outstanding balance decreases, and so does the interest charged in subsequent months. This is more borrower-friendly than the flat rate method used by some money lenders, where interest is calculated on the full original amount throughout the tenure.
Beyond the interest rate and tenure, consider processing fees (0.5–2% of loan amount at most banks), prepayment penalties (typically waived for floating-rate home loans under RBI guidelines but applicable for fixed-rate loans and NBFCs), and mandatory insurance requirements. This calculator includes processing fees in the total cost comparison.

❓ Frequently Asked Questions
🔗 Related Calculators
How do I decide between two loan offers?
Compare the total interest paid over the full tenure - this is the true cost of borrowing. A lower EMI achieved through a longer tenure often means you pay significantly more total interest. Use this calculator to see the total cost for both options side by side. Also check for hidden fees: processing fee, prepayment penalty, insurance requirements.
Is it better to take a shorter loan tenure or a longer one?
A shorter tenure means higher EMI but lower total interest paid. A longer tenure means lower EMI but you pay more interest overall. For example, a ₹20L loan at 9% for 10 years costs ₹10.5L in interest, while the same loan for 20 years costs ₹22.6L - more than the principal itself. Choose the shortest tenure your budget can comfortably manage.
What is the impact of a 0.5% difference in interest rate?
On a ₹20 lakh loan for 20 years, a 0.5% lower rate (say 8.5% vs 9%) saves approximately ₹1.1 lakh in total interest. On a ₹50 lakh home loan for 25 years, the same 0.5% difference saves nearly ₹4 lakhs. Even small rate differences compound significantly over long loan tenures.
Should I refinance my existing loan if I get a better rate?
Refinancing makes sense if the interest saving exceeds the switching costs (processing fee on new loan + prepayment penalty on old loan). A general rule: refinance if the rate difference is at least 0.5–1% and you have significant tenure remaining. Use this calculator to compare your current loan vs. the refinancing offer to quantify the savings.
What is the difference between flat rate and reducing balance interest?
A flat rate calculates interest on the full principal for the entire tenure. A reducing balance rate calculates interest only on the outstanding principal, which decreases each month as you repay EMIs. A flat rate of 8% is roughly equivalent to a reducing balance rate of 14–16%. Always compare loans on a reducing balance basis - most bank loans use reducing balance.
How do I compare a longer vs shorter loan tenure?
A longer tenure reduces your monthly EMI but increases total interest paid substantially. Example: ₹10L at 10% - 3-year tenure: EMI ₹32,300, total interest ₹1.62L. 5-year tenure: EMI ₹21,250, total interest ₹2.75L. The 5-year option saves ₹11,050/month but costs ₹1.13L more in total. Use the loan comparison calculator to quantify this trade-off for your specific loan amounts and decide based on your cash flow needs.
Should I choose a lower EMI or lower total cost?
It depends on your cash flow situation. If your monthly budget is tight, a lower EMI (longer tenure) may be necessary to avoid default risk. However, if you can manage a higher EMI, the lower total cost option always wins financially. A useful approach: choose the shortest tenure whose EMI you can comfortably pay while maintaining 3–6 months of emergency fund. Never stretch to a loan where the EMI exceeds 40% of your net monthly income.
What is the break-even point when comparing two loan options?
The break-even is when the total cost (interest + fees) of both loans is equal. Loan A may have a lower rate but higher processing fee; Loan B has a higher rate but no fee. If you prepay Loan A in year 1, the lower rate does not compensate for the fee. This calculator computes total cost over time so you can see which option is cheaper for your planned tenure.
