How Loan Payments Are Calculated
Monthly loan payment (also called EMI — Equated Monthly Installment) is calculated using the amortization formula:
M = P × [r(1+r)^n] / [(1+r)^n − 1]
Where:
- M = Monthly payment
- P = Principal (loan amount)
- r = Monthly interest rate (annual APR ÷ 12)
- n = Total number of payments (years × 12)
Example: ৳2,750,000 auto loan at 7% APR for 5 years:
r = 0.07/12 = 0.005833, n = 60
M = 25,000 × [0.005833 × (1.005833)^60] / [(1.005833)^60 − 1] = ৳54,450.03/month
Total paid: ৳54,450.03 × 60 = ৳3,267,220. Total interest: ৳517,220.
Loan Payment Comparison: How Rate and Term Affect Cost
Even small differences in interest rate or loan term create large differences in total cost. This table shows a ৳2,200,000 loan at various rates and terms:
| Interest Rate | Loan Term | Monthly Payment | Total Interest | Total Cost |
|---|---|---|---|---|
| 5% | 3 years | ৳65,890 | ৳171,820 | ৳2,371,820 |
| 7% | 3 years | ৳67,980 | ৳246,070 | ৳2,446,070 |
| 10% | 3 years | ৳70,950 | ৳354,970 | ৳2,554,970 |
| 5% | 5 years | ৳41,470 | ৳291,060 | ৳2,491,060 |
| 7% | 5 years | ৳43,560 | ৳413,710 | ৳2,613,710 |
| 10% | 5 years | ৳46,750 | ৳604,560 | ৳2,804,560 |
| 15% | 5 years | ৳52,360 | ৳942,370 | ৳3,142,370 |
A 2-year longer term saves ৳24,420/month but costs an extra ৳122,650 in total interest (5% example). At 15% APR, a 5-year loan costs nearly ৳770,000 more in interest than a 5% loan — choose your lender carefully.
Types of Loans: Personal, Auto, Student, and Business
Different loan types have distinct structures, typical rates, and use cases:
| Loan Type | Typical APR Range | Typical Term | Secured? |
|---|---|---|---|
| Personal Loan (good credit) | 6–12% | 2–7 years | Usually unsecured |
| Personal Loan (fair credit) | 12–25% | 2–5 years | Usually unsecured |
| Auto Loan (new car) | 5–9% | 36–84 months | Yes (car) |
| Auto Loan (used car) | 7–15% | 24–72 months | Yes (car) |
| Federal Student Loan | 5.5–8.5% | 10–25 years | No |
| Payday Loan | 200–400%+ | 2–4 weeks | No |
| Home Equity Loan | 6–9% | 5–30 years | Yes (home) |
| Business Loan (SBA) | 6–11% | 1–25 years | Often required |
Secured loans (backed by collateral) typically offer lower rates. Never take a payday loan except as an absolute last resort — the effective APR can exceed 400%, and the short repayment window traps many borrowers in a debt cycle.
Understanding APR, Interest Rate, and Fees
The difference between interest rate and APR (Annual Percentage Rate) is critical when comparing loan offers:
- Interest rate: The annual cost of borrowing the principal only — does not include fees
- APR: Includes the interest rate plus all mandatory fees (origination fees, closing costs, mortgage insurance) expressed as an annualized rate
Example: Two lenders offer loans:
- Lender A: 7.0% interest rate, ৳0.00 origination fee → APR: 7.0%
- Lender B: 6.75% interest rate, 1% origination fee (৳27,500 on a ৳2,750,000 loan) → APR: ~7.2%
Lender B's lower advertised interest rate actually costs more. Always compare APR, not just interest rate.
Common loan fees to watch for:
- Origination fee: 1–8% of loan amount
- Prepayment penalty: fee for paying off early (some lenders)
- Late payment fee: typically ৳1,650–৳4,400 or 5% of payment
- NSF (insufficient funds) fee: ৳2,200–৳5,500 per failed payment
Strategies to Pay Off Loans Faster and Save on Interest
Every dollar of extra payment goes directly to principal, reducing future interest charges:
- Extra monthly payments: Adding just ৳5,500/month to a ৳2,200,000 loan at 7% for 5 years saves ৳31,680 in interest and pays off 3 months early.
- Biweekly payments: Making half-payments every two weeks (26 payments/year instead of 12) equals 13 monthly payments per year. This can save months of payments on longer loans.
- Lump sum payments: Apply tax refunds, bonuses, or extra income directly to principal. Even a single ৳110,000 extra payment in year 1 on a 5-year ৳2,750,000 loan at 7% saves approximately ৳33,000 in total interest.
- Refinancing: If your credit score has improved or market rates have dropped 1%+, refinancing can significantly reduce your rate and total cost.
The avalanche method for multiple debts: List all debts by interest rate (highest first). Pay minimum on all, then put all extra money toward the highest-rate debt. Once paid off, redirect that payment to the next highest. This minimizes total interest paid.
The snowball method: Pay off smallest balance first regardless of rate. Provides psychological wins but costs more in total interest. Research shows either method works — pick the one you will stick with.
How Your Credit Score Affects Loan Rates
Your credit score is the single most influential factor in the interest rate you will be offered. Here is the impact across different score ranges:
| Credit Score | Rating | Typical Personal Loan APR | Monthly Payment (৳2,200K, 5yr) | Total Interest |
|---|---|---|---|---|
| 750–850 | Excellent | 6–8% | ৳42,460–৳44,660 | ৳347,600–৳477,400 |
| 700–749 | Good | 9–13% | ৳45,650–৳50,160 | ৳539,000–৳807,400 |
| 650–699 | Fair | 14–20% | ৳51,260–৳58,190 | ৳873,400–৳1,291,400 |
| 600–649 | Poor | 21–30% | ৳59,620–৳67,430 | ৳1,375,000–৳1,843,600 |
| Below 600 | Very Poor | 30%+ or declined | ৳67,430+ | ৳1,843,600+ |
Quick ways to improve your credit score before applying for a loan:
- Pay down existing credit card balances to below 30% utilization (this is fast — can improve score within a billing cycle)
- Ensure no missed payments in the last 12 months
- Do not open new credit lines within 3–6 months of applying for a major loan
- Check your credit report for errors and dispute any inaccuracies

Frequently Asked Questions
How can I pay off my loan faster?
Make extra payments directly to principal. Even ৳5,500–৳11,000 extra per month significantly reduces total interest. Use the avalanche method for multiple debts: pay minimum on all, then extra on the highest-rate debt first. Biweekly payments (half-payment every 2 weeks) add one full extra payment per year.
What is the difference between APR and interest rate?
The interest rate is the base cost of borrowing. APR (Annual Percentage Rate) includes the interest rate plus all mandatory fees (origination fees, points, etc.), expressed as an annual percentage. APR is always ≥ interest rate and gives the true cost for comparison. Always compare APRs when shopping for loans.
Should I consolidate my loans?
Debt consolidation makes sense if it lowers your overall interest rate and you have strong commitment to not accumulating new debt. Calculate the total interest paid under each scenario. A lower monthly payment with a longer term can actually cost more in total interest even at a lower rate.
What credit score do I need for a personal loan?
Most lenders require a minimum of 580–600, but rates are significantly better above 700. With a 750+ score, you qualify for the best rates (often 6–8% APR). Below 600, consider credit unions, secured loans, or credit-builder programs to improve your score before borrowing.
Is it better to get a shorter or longer loan term?
Shorter term = higher monthly payment but less total interest. Longer term = lower monthly payment but significantly more total interest. As a rule, choose the shortest term you can comfortably afford. Never extend a term just to afford a purchase that is outside your budget.
What is an origination fee on a loan?
An origination fee is a one-time charge by the lender for processing the loan, typically 1–8% of the loan amount. On a ৳2,750,000 loan, a 3% origination fee = ৳82,500 deducted from the disbursed amount (you receive ৳2,667,500 but repay ৳2,750,000). Factor this into your APR comparison.
Can I get a loan with no credit history?
Yes, but options are limited and rates may be higher. Try: credit unions (more flexible), secured loans (backed by savings account), credit-builder loans specifically designed for building history, or a co-signer with good credit. Some online lenders use alternative data (income, employment history) beyond credit score.
What happens if I miss a loan payment?
A missed payment typically triggers a late fee (৳1,650–৳4,400 or 5% of the payment). After 30 days, it may be reported to credit bureaus, dropping your credit score by 60–100 points. After 90–120 days, the loan may go to collections or default. Most lenders offer hardship programs — contact them immediately if you anticipate missing a payment.
