Personal Loan Calculator — Sri Lanka
Enter the loan amount, the interest rate offered to you and the tenure. The calculator uses the reducing-balance formula every Sri Lankan bank applies to personal loans and shows the monthly instalment, total repayment, total interest and full amortisation schedule. All maths runs in your browser — nothing is sent anywhere.
What the calculator does and doesn't include
- Included: reducing-balance monthly instalment on the principal, at the rate and tenure you enter. This is the number you see on your monthly loan statement.
- Not included — processing fees. Sri Lankan banks typically charge 1 to 2 percent of the loan amount as a one-time processing fee. Some cap it (LKR 25,000–50,000); some waive it for salary-account holders. Add the fee to the total repayment shown here to get the true all-in cost.
- Not included — stamp duty and CRIB. Stamp duty on the loan agreement is statutory. A CRIB report costs around LKR 650. These are small but real.
- Not included — early settlement fees. If you settle within the first 1–3 years, most banks charge 1 to 3 percent of the outstanding balance. The calculator assumes you pay the full tenure.
- Rate type matters. This is a reducing-balance calculator. If a lender has quoted a flat rate, the effective reducing-balance rate is materially higher — confirm which rate type they're quoting before you compare.

Questions
How does this personal loan calculator work?
It uses the standard reducing-balance EMI formula that Sri Lankan banks apply to personal loans. Enter the loan amount, the annual interest rate offered to you, and the tenure in years. The result shows your monthly instalment, the total amount you will repay over the tenure, and the total interest cost. The amortisation table breaks each monthly instalment down into its interest and principal components.
Does this calculator include processing fees and stamp duty?
No. Processing fees, stamp duty, CRIB report charges and any other one-time costs are separate. Sri Lankan banks typically charge 1 to 2 percent of the loan amount in processing fees. Add these to the total repayment shown by the calculator to get the all-in cost of borrowing before comparing offers.
What is the difference between reducing balance and flat rate?
Reducing balance charges interest each month on the outstanding principal, so the interest share of each instalment shrinks over time. Flat rate charges interest on the full original loan amount for the whole tenure — the same headline rate produces a much higher effective cost. Mainstream Sri Lankan personal loans use reducing balance; if a lender quotes a flat rate, ask what the equivalent reducing-balance rate is before comparing.
Can I compare two loan scenarios side by side?
Yes. The two scenario columns let you compare different rates, tenures or loan amounts. Useful for weighing a fixed rate against a variable one, a shorter tenure at a lower rate against a longer tenure at a higher rate, or one bank's offer against another's.
Is my loan data sent anywhere?
No. The calculator runs entirely in your browser. The numbers you enter are not sent to Advice.lk or any third party, and nothing is stored between visits.
