Before you borrow
- This is an estimate. Processing fees, other charges, rounding and the day-count method can make the lender's actual EMI differ.
- Ask the lender in writing whether the rate is flat or reducing. At the same headline rate, flat costs much more.
- Compare the total cost including fees, not just the EMI, and check the lender's written repayment schedule.
- No bank's rate is shown or recommended; the calculation uses the rate you enter.

Frequently Asked Questions (FAQ)
How is EMI calculated?+
On a reducing balance, EMI = P × r × (1+r)^n ÷ ((1+r)^n − 1), where P is the principal, r the monthly rate (annual rate ÷ 12 ÷ 100) and n the number of instalments. At zero interest EMI = P ÷ n. For example ৳1,00,000 at 12% for 12 months gives an EMI of about ৳8,884.88.
What is the difference between flat and reducing balance?+
A flat rate charges interest on the original amount for the whole term: total interest = P × annual rate × (months ÷ 12), EMI = (P + interest) ÷ months. A reducing balance charges interest only on what you still owe, so total interest is much lower at the same rate. ৳1,00,000 at 12% for 12 months costs ৳12,000 flat but about ৳6,619 reducing.
What is an amortization schedule?+
A month-by-month table showing how much of each instalment goes to principal and to interest, and the balance left afterwards. On a reducing balance the interest share is largest at the start.
Why is the last instalment slightly different?+
Each instalment is rounded to the paisa. The small rounding difference is adjusted in the last instalment so the balance ends at exactly zero.
Why doesn't it match my bank's EMI?+
Processing fees and other charges, rounding, the day-count method and the start date can make the actual EMI differ. Check the lender's written repayment schedule.

What EMI is and why it matters
An EMI (Equated Monthly Instalment) is the fixed monthly repayment, part interest and part principal. Knowing the EMI and total interest before borrowing makes budgeting and comparing offers easier.
At the same headline rate a flat-rate loan can cost up to about twice the interest of a reducing-balance loan, because interest is charged on the original amount for the whole term. Always ask which method applies.
