Loan EMI Calculator
Estimate the monthly instalment, total interest and total repayment for a reducing-balance loan. The calculator appears first so you can compare scenarios before reading the explanation.

How to use this calculator
- Enter only the amount you intend to borrow.
- Enter the annual rate quoted for the loan.
- Convert the tenure to months and select Calculate EMI.
- Read EMI, total interest and total paid together.
- Open the amortisation statement to see how each payment is split.
Try a shorter and a longer tenure. This makes the affordability-versus-cost trade-off visible. Keep fees outside the principal unless the lender finances them and clearly states that interest applies to them.
Formula and assumptions
EMI = P × r × (1+r)n ÷ ((1+r)n − 1)
P is principal, r is the annual percentage rate divided by 12 and 100, and n is the number of monthly payments. The tool assumes a constant rate, monthly reducing balance and on-time payments. At 0% interest, EMI is principal divided by months.
It excludes processing fees, insurance, stamp duty, late fees, taxes and rate changes. Actual lender schedules can differ because of disbursal dates and rounding.
Worked example
Suppose an Indian salaried borrower considers ₹5,00,000 at an illustrative 10.5% annual rate for 60 months.
| Estimated monthly EMI | ₹10,747 |
|---|---|
| Estimated total interest | ₹1,44,817 |
| Estimated total repayment | ₹6,44,817 |
The EMI may appear manageable, but the example shows why total interest matters. These values are rounded and illustrative; actual lender schedules and charges vary.
How to interpret the result
The EMI is the estimated recurring payment if the rate and tenure remain unchanged. Total interest is the estimated borrowing cost above principal. Total repayment combines principal and interest, but not external charges.
Common mistakes
- Choosing tenure only to reach the lowest EMI.
- Ignoring processing fees and insurance.
- Comparing headline rates without reading fixed or floating conditions.
- Using the maximum eligible amount as the affordable amount.
- Leaving no room for essential expenses and emergency savings.
Practical borrowing tips
- Compare total repayment across at least two tenures.
- Keep a buffer for changing household costs.
- Read the sanction letter and repayment schedule.
- Ask how part-payment, foreclosure and rate changes are handled.
- Avoid additional borrowing merely because eligibility is higher.
Use the Debt-to-Income Calculator and Loan Eligibility Calculator as separate affordability checks.
How to reduce interest after taking the loan
Interest is generally calculated on the outstanding principal, so reducing principal earlier may lower future interest. When affordable, consider part-prepayments, a modest EMI increase after income growth, or keeping the original EMI when a rate reduction would otherwise extend the tenure. Review refinancing only after comparing remaining interest, new fees and break-even time.
Check prepayment or foreclosure terms first. Do not assume they are free, and do not drain emergency savings or miss essential expenses to prepay. Avoid tenure extensions unless cash-flow needs justify the extra potential interest. Review statements periodically and correct unexplained charges promptly.

Frequently asked questions
What is an EMI?
An EMI is a regular monthly payment combining principal repayment and interest.
How is loan EMI calculated?
The reducing-balance formula uses principal, monthly interest rate and monthly payment count.
Does a longer tenure reduce EMI?
Usually yes, but more months can increase total interest.
Does lower EMI mean a cheaper loan?
No. Compare total interest, total repayment, fees and conditions.
Does this include processing fees?
No. Fees, insurance, taxes and penalties are excluded.
Can prepayment reduce interest?
It may, but check lender terms and preserve an emergency buffer.
What if the rate changes?
A floating-rate change may alter EMI, tenure or both; this estimate holds the rate constant.
Is this a lender quote?
No. It is a simplified educational estimate.
