Banks usually charge interest on the reducing balance: only on what you still owe, so the interest part of each instalment shrinks. Some lenders quote a flat rate instead, charging interest on the full amount for the whole term. The same number then costs much more.
| Figure | Reducing balance at 9% | Flat rate at 9% |
|---|---|---|
| Monthly instalment | ৳20,758.36 | ৳24,166.67 |
| Total interest | ৳2,45,501.31 | ৳4,50,000.00 |
| Total you pay back | ৳12,45,501.31 | ৳14,50,000.00 |
A 9% flat rate over 5 years costs about the same as 15.71% on a reducing balance.
Flat interest = amount × rate × years = ৳10,00,000.00 × 9% × 5 = ৳4,50,000.00. Flat instalment = (amount + interest) ÷ 60 months. The equivalent reducing rate is found by trying rates until the instalments match.
EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1)
P is the loan amount, r the monthly rate (the yearly rate ÷ 12 ÷ 100) and n the number of months. At 0% the instalment is simply P ÷ n.
Each month, interest is the balance still owed × r. The rest of the instalment pays down the loan, so later instalments are mostly principal.
Banks may round instalments or count days differently, so their figures can differ by a little.
