Vehicle Finance Calculator Sri Lanka

Estimate a car, van, motorcycle, or three-wheeler finance payment in Sri Lankan rupees. Use the rate and terms quoted by your bank or finance company.

Enter your vehicle finance details

Enter the amount you plan to pay upfront. Any additional deposit, trade-in, or fees should be included only if your lender treats it as part of the advance.

Check your offer letter. A flat rate and a reducing-balance rate are not directly comparable, even when the percentages look the same.

WORKED EXAMPLE · REDUCING BALANCEVehicle Rs. 8,500,000 · down payment Rs. 5,100,000 · 18.5% p.a. · 60 months

Estimated amount financed Rs. 3,400,000 · monthly instalment about Rs. 87,265. This sample is not a CBSL eligibility check; lender valuation and vehicle classification apply.

What this estimate includes The financed amount is vehicle price minus your down payment. The reducing-balance estimate applies monthly interest to the remaining balance; the flat-rate estimate applies simple interest to the original financed amount for the full term.

CBSL maximum loan-to-value limits for motor-vehicle finance changed with effect from 25 May 2026. This calculator estimates payments from the amount you enter; it does not determine how much a lender may approve. Check the latest CBSL vehicle-finance direction and confirm the eligible amount, valuation, fees, and repayment schedule with your lender.

This is an estimate, not an offer, approval, or financial advice. It excludes insurance, valuation, documentation and other charges, and any balloon or residual payment. The lender's written quotation and repayment schedule take precedence.

How to estimate a vehicle finance payment in Sri Lanka

Enter the vehicle price, the cash advance you plan to pay, the annual rate quoted by your lender, and the repayment period in months. The calculator subtracts the advance from the price to estimate the financed amount, then calculates the instalment using your selected interest method.

Reducing-balance formula: monthly payment = financed amount × monthly rate ÷ (1 − (1 + monthly rate)−number of payments). The monthly rate is the annual rate divided by 12. At a 0% rate, the financed amount is divided evenly by the number of payments.

Flat-rate formula: total interest = financed amount × annual rate × years. The estimated monthly payment is (financed amount + total interest) ÷ number of months.

Compare quotations using the same financed amount and term, and check whether each quotation uses a flat or reducing-balance rate. A lender may use its own valuation and CBSL vehicle category when applying the current loan-to-value limits. See the general loan and instalment calculator for other borrowing estimates.

Vehicle finance calculator FAQs

How much down payment do I need for a vehicle in Sri Lanka?

The required down payment depends on the vehicle classification, its market valuation, the applicable CBSL loan-to-value direction, and the lender's assessment. Use the lender-approved finance amount when planning a purchase.

Does this calculator include leasing fees and insurance?

No. The estimate covers the financed principal and interest method you select. Ask the lender for a complete schedule including fees, insurance, taxes, and any final or residual payment.

Is a flat rate the same as a reducing-balance rate?

No. A flat rate applies interest to the original financed amount for the full term. A reducing-balance calculation applies interest to the unpaid balance, which falls as payments are made.
