Loan Calculator Sri Lanka

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 at 14.5% over 5 years, the estimated monthly repayment is LKR 58,821.

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.

Methodology and review

How this calculation is produced

• This tool converts your amount, rate, and term inputs into an estimate using the finance formula defined for the calculator.
• The result is intended to help compare scenarios quickly before you rely on lender-specific fees, taxes, penalties, or product conditions.
• If the underlying product uses a different compounding method or pricing structure, the final real-world number may differ from the estimate shown here.

What to verify before relying on it

• Verify lender rates, compounding, fees, and eligibility rules against the relevant bank or provider before making a commitment.
• Compare the output with official product documents or current rate tables when the decision affects borrowing or savings.
• Use the result for screening and negotiation, then confirm details with the provider or a qualified adviser.

When this tool is useful

• Use this to pressure-test affordability before speaking to banks or lenders.
• Use it when comparing several rates, terms, or savings timelines side by side.
• Use it again whenever rates, tenure, or contribution assumptions change.

How to read the result

• Focus on the total cost and monthly cash-flow impact, not only the headline rate.
• Use the result as a planning estimate before final lender fees, taxes, or eligibility checks.
• If the tool shows several metrics, compare the tradeoff between payment size and total cost over time.

Common mistakes

• Comparing offers by monthly payment alone while ignoring total interest or maturity value.
• Using rates that do not match the real bank product, compounding method, or fee structure.
• Forgetting that approval conditions and documentation can change the final offer.

Good next steps

• Compare this output with rate pages, bank tables, or a second related calculator.
• Check whether fees, taxes, insurance, or penalties need to be added before deciding.
• Keep a margin of safety in the budget instead of planning at the absolute limit.
