EMI Calculator — Work Out Your Monthly Loan Payment Instantly

By sadiqbd · June 6, 2026

Before you sign a loan, know exactly what you're committing to each month

Most people approach a loan backwards. They decide they want something — a flat, a car, a laptop for the business — figure out what they can borrow, and only then ask "so what's the monthly payment?" The answer sometimes lands fine. Other times it lands like a punch: the number is higher than expected, the tenure is longer than comfortable, and backing out at that point is awkward.

The smarter move is to run the EMI calculation before you walk into the bank. Know the number going in, not after you've signed. That's exactly what an EMI calculator is for.

What Is EMI?

EMI stands for Equated Monthly Installment — the fixed amount you pay your lender every month for the duration of a loan. It's "equated" because the amount stays the same each month, even though the split between principal and interest shifts over time. Early payments are mostly interest; later payments are mostly principal.

Every EMI is calculated from three inputs:

P — the principal (the loan amount)
r — the monthly interest rate (annual rate ÷ 12)
n — the number of monthly installments (loan tenure in months)

The formula is:

EMI = P × r × (1 + r)^n / [(1 + r)^n − 1]

It looks intimidating, but it's a single calculation once you have your numbers. At 10% annual interest on ৳5,00,000 for 3 years:

r = 10% ÷ 12 = 0.8333% per month = 0.008333
n = 36 months
EMI = 5,00,000 × 0.008333 × (1.008333)^36 / [(1.008333)^36 − 1]
EMI ≈ ৳16,134 per month

Total amount paid over 3 years: ৳5,80,824. Total interest paid: ৳80,824.

That's the number worth knowing before you sign.

How to Use the EMI Calculator on sadiqbd.com

Three inputs, instant result.

Enter the loan amount — the principal you're borrowing, not the asset price. If you're putting down a deposit, enter the loan amount after the down payment.
Enter the annual interest rate — use the rate your lender quotes. The calculator converts it to monthly automatically.
Enter the loan tenure — in months or years depending on the calculator. A 5-year loan is 60 months.
Read the EMI — the monthly payment appears immediately. Most calculators also show total interest payable and total amount paid, which puts the cost of the loan in perspective.

Adjust any input and the result updates instantly. This makes it easy to test scenarios: what if I borrow ৳2 lakh less? What if I stretch the tenure by a year? What if the rate goes up by 0.5%?

Real-World Examples

Home loan planning

Nasrin is considering a ৳40,00,000 home loan at 9% annual interest for 20 years.

r = 9% ÷ 12 = 0.75% per month
n = 240 months
EMI ≈ ৳35,989 per month

Total paid over 20 years: ৳86,37,360. Total interest: ৳46,37,360 — more than the original loan amount. That's not unusual for long-tenure home loans; it's just the reality of borrowing over 20 years. Seeing that number upfront helps her decide whether to put down a larger deposit, choose a shorter tenure, or look for a lower rate.

Car loan comparison

Rafiq wants to buy a car and is comparing two offers:

Bank A: ৳8,00,000 at 11% for 5 years → EMI ≈ ৳17,391
Bank B: ৳8,00,000 at 10.5% for 5 years → EMI ≈ ৳17,199

The EMI difference is only ৳192 per month. But over 60 months, Bank B saves him ৳11,520 in total interest. Worth knowing, even if it's not a dramatic difference.

Personal loan for a short-term need

Tania needs ৳1,50,000 quickly and is considering a personal loan at 14% for 2 years.

EMI ≈ ৳7,218 per month
Total interest: ৳23,232

She can afford the monthly payment, but the 14% rate means she's paying ৳23,000 on top of what she borrowed. If she can repay in 1 year instead of 2, the EMI goes up to ৳13,582 but total interest drops to ৳12,984 — saving her ৳10,000. The EMI calculator lets her test this tradeoff in seconds.

What Actually Affects Your EMI

The interest rate has the biggest impact on total cost over long tenures, though its effect on the monthly EMI can feel small month-to-month. On a ৳20 lakh loan for 15 years, the difference between 9% and 10% is about ৳1,100 per month — but ৳1,98,000 in total interest over the life of the loan.

The tenure has the biggest impact on the monthly payment. A longer tenure means a lower EMI but dramatically more total interest paid. A ৳10 lakh loan at 10%:

5 years: EMI ৳21,247 · total interest ৳2,74,820
10 years: EMI ৳13,215 · total interest ৳5,85,808
15 years: EMI ৳10,746 · total interest ৳9,34,280

Stretching from 5 to 15 years cuts the monthly payment by ৳10,500 — but costs you an extra ৳6.6 lakh in interest. That's the trade-off every borrower is making, often without fully seeing the numbers.

The principal has a straightforward linear relationship: double the loan, double the EMI and double the total interest, all else equal. This is why reducing the loan amount (larger down payment, smaller purchase) is often the most effective lever.

Tips for Using the EMI Calculator Effectively

Test the "stretch" scenario before accepting it. Lenders sometimes suggest longer tenures to make the EMI look affordable. Run both options — shorter and longer — and look at total interest paid, not just the monthly number.

Factor in processing fees and other charges. Your actual cost of borrowing is higher than the interest rate alone. Processing fees, insurance requirements, and prepayment penalties all affect the real cost. The EMI calculator gives you the base number; add fees on top for a complete picture.

Use it to reverse-engineer the loan amount. If you know what monthly payment you can afford, work backwards: try different principal amounts until the EMI fits your budget. Most people do this mentally; doing it in the calculator takes 30 seconds and gives you a precise maximum loan amount.

Compare floating vs. fixed rates. Fixed-rate loans give you a predictable EMI for the full tenure — easy to calculate. Floating rates change with the market, so calculate your EMI at a few different rate scenarios (current rate, current rate + 1.5%, current rate + 3%) to understand your exposure if rates rise.

Check the impact of part-prepayments. Many loans allow you to make lump-sum prepayments that reduce your outstanding principal. After a prepayment, recalculate your EMI at the new outstanding amount to see how much shorter your effective tenure becomes.

Frequently Asked Questions

Does EMI change over the loan tenure? With a standard fixed-rate loan, the EMI stays the same every month. What changes is the split: early payments are mostly interest, later payments are mostly principal. This is called amortisation. The total monthly outflow remains constant.

What happens if I miss an EMI payment? Missing a payment usually triggers a penalty and the overdue amount carries interest. Repeated misses affect your credit score and can lead to the lender classifying the loan as a non-performing asset. If you're struggling, contact the lender early — most have restructuring options.

Is a lower EMI always better? Not necessarily. A lower EMI usually means a longer tenure, which means significantly more total interest paid. If you can afford a higher EMI, shorter tenures almost always save you money overall.

Can I use this calculator for home loans, car loans, and personal loans? Yes — the EMI formula is the same regardless of loan type. The inputs (principal, rate, tenure) differ, but the calculation works identically. Just use the correct interest rate and tenure for each product.

Is the EMI calculator free? Completely free, no sign-up, no limit on calculations.

The EMI formula doesn't care whether the number surprises you or not — it gives you the same answer either way. Running it before you borrow puts you in a much stronger position: you know what you're committing to, you can negotiate from an informed position, and you're not discovering an uncomfortable payment size after the paperwork is done.
