How this calculator works
- Enter the loan amount, annual interest rate, and repayment period in years.
- The calculator uses a standard amortization formula to estimate the monthly installment, total interest, and total repayment.
- Below the calculator, the page also shows indicative published personal-loan rates from major Sri Lanka banks for quick comparison.
Worked example
For a loan of LKR 2,500,000.00 at 14.5% over 5 years, the estimated monthly repayment is LKR 58,820.70.
Important assumptions
- Interest is treated as a fixed annual rate across the full term.
- Repayments are assumed to be monthly and on time.
- Bank fees, insurance, taxes, and early settlement charges are not included in the calculator result.
- The bank-rate table below shows indicative published personal-loan rates, not personalized offers.
