When comparing online loans, many borrowers focus only on the headline interest rate. Big mistake. What matters is the total cost—principal plus all interest and fees. This guide breaks down how to compare rates fairly and understand what you're actually paying.
Online lenders in Sri Lanka typically use one of two methods to calculate interest:
Flat rate means you pay the same interest regardless of how long you hold the loan (up to the maximum term). Example: Borrow Rs 10,000 at a flat 10% rate for 30 days. You pay Rs 1,000 in interest, period.
Advantage: Simple to calculate. You know exactly what you'll pay upfront.
Disadvantage: If you repay early, you've paid more interest than you'd owe under reducing balance.
Interest is calculated daily on what you still owe. The less you owe, the less interest accrues. Example: Borrow Rs 10,000 at 10% annual rate. Each day, interest is calculated on your remaining balance. If you pay half in 15 days, your remaining interest is calculated on Rs 5,000, not Rs 10,000.
Advantage: Rewards early repayment. Pay in half the time, pay roughly half the interest.
Disadvantage: More complex to calculate. You need a calculator or the lender's app to know your exact cost.
Larger loans often have lower interest rates because the lender's processing cost is spread over a bigger amount. A Rs 100,000 loan might be cheaper (percentage-wise) than a Rs 5,000 loan.
Longer terms typically have higher total interest but lower daily accrual. A 30-day loan accrues interest faster than a 90-day loan (on a daily basis), but the total interest paid over 90 days will be higher if you're charged the same annual rate.
If you've borrowed before and repaid perfectly, lenders reward you with lower rates. Repeat borrowers get better deals than first-timers.
Lenders compete on rates. Crezu might offer slightly lower rates than OnCredit, or vice versa. Compare before applying.
| Lender | Min Loan | Max Loan | Min Term | Max Term | Rate Structure |
|---|---|---|---|---|---|
| Crezu | Rs 1,000 | Rs 50,000 | 1 day | 30 days | Varies; lower for repeat borrowers |
| OnCredit | Rs 5,000 | Rs 40,000 | 7 days | 183 days | Decreasing balance rate structure |
| CashX | Rs 5,000 | Rs 50,000 | 5 days | 30 days | Competitive rates; varies by credit |
| Fino | Rs 3,000 | Rs 20,000 | 5 days | 30 days | Beginner-friendly; higher rates for first-timers |
| LoanPlus | Rs 5,000 | Rs 80,000 | 7 days | 30 days | Flat rate; transparent pricing |
| CashX Lite | Rs 5,000 | Rs 200,000 | 7 days | 90 days | Rates lower for large/longer loans |
Step 1: Note the principal (amount you're borrowing).
Step 2: Note the interest rate and structure (flat or reducing balance).
Step 3: Note any additional fees (processing fee, late payment fee, etc.).
Step 4: Calculate total interest using the lender's formula or calculator.
Step 5: Add principal + interest + fees = total cost.
Example (Flat Rate):
Example (Reducing Balance):
A lender with a 10% flat rate isn't automatically better than one with a 9% reducing balance rate. The total cost depends on your specific loan.
Scenario 1: Borrow Rs 5,000 for 30 days.
Lender A: 10% flat = Rs 500 cost.
Lender B: 9% annual reducing = ~Rs 150 cost.
Winner: Lender B by far.
Scenario 2: Borrow Rs 30,000 for 90 days.
Lender A (doesn't offer 90-day terms): Not an option.
Lender B (9% annual reducing): ~Rs 700 cost.
Lender C (CashX Lite, 12% for long term): ~Rs 900 cost.
Winner: Lender B again, but choice depends on other factors (approval odds, disbursement speed, etc.).
Hidden fees: Some lenders advertise a low rate but hide fees (processing, documentation, late payment, prepayment penalties). Ask for the full breakdown.
Misleading annual rates: A lender might advertise "9% annual" on a 7-day loan, which is much more expensive than 9% annualized (the actual annualized cost is 9% × 52 weeks ÷ 1 week). Always ask for the total cost in rupees, not just the rate.
No mention of total cost: If a lender won't tell you the exact amount you'll repay (principal + interest + all fees), move on. Legitimate lenders are transparent.
Build your credit history. Repeat borrowers get lower rates. Take a small loan, repay perfectly, then borrow again. Your rate improves with each successful loan.
Borrow larger amounts. Per-rupee borrowing costs are often lower for bigger loans. Borrowing Rs 50,000 is often cheaper (proportionally) than Rs 5,000.
Accept longer terms. A 30-day loan accrues interest faster than a 90-day loan. If you can afford to repay over time, a longer term reduces daily interest charges.
Compare total cost, not just the rate. Call or email two lenders with the same scenario (e.g., Rs 20,000 for 30 days) and ask for the exact total cost. Compare these numbers, not the advertised rates.
Prepay if possible. Many lenders let you repay early without penalty. If you get paid before your due date, pay immediately—this saves you interest.
Online loan interest rates in Sri Lanka vary widely based on loan amount, term, lender, and your credit history. Don't be dazzled by low-sounding percentages. Ask for the total cost in rupees, compare that number across lenders, and choose accordingly. The lender offering the lowest total cost for your specific scenario is the best deal.
