How EMI is calculated

EMI (equated monthly instalment) is the fixed amount you pay each month until the loan is cleared. This calculator uses the standard reducing-balance method, where interest is charged only on the amount you still owe:

EMI = P × r × (1 + r)ⁿ / ((1 + r)ⁿ − 1)

• P is the amount you borrow (car price minus down payment)
• r is the monthly interest rate (yearly rate divided by 12, then by 100)
• n is the number of monthly payments

Flat rate or reducing balance? Some leasing and loan quotes are given as a flat rate, where interest is worked out on the full original amount for the whole term. A flat rate costs more than a reducing-balance rate with the same number. The Central Bank of Sri Lanka gives an example: on Rs. 100,000 over one year at 10%, a flat rate charges Rs. 10,000 in interest, while a reducing-balance rate charges about Rs. 5,499. Always ask the lender for the reducing-balance or effective rate, and enter that rate here.

Car loan vs leasing in Sri Lanka

• Car loan (vehicle loan): a bank or finance company lends you the money. The car is usually registered as security until you pay off the loan.
• Leasing (finance lease): a registered leasing company buys the car and you pay a monthly rental to use it. The leasing company stays the legal owner until the lease ends and the agreed final payment is made, and then ownership is transferred to you as agreed in the contract. Finance leases are governed by the Finance Leasing Act No. 56 of 2000 and cannot run for less than one year.
• Hire purchase: similar to leasing, but covered by a different law (the Consumer Credit Act). You own the car once the last instalment is paid.

The monthly figure for all three depends on the same four inputs, so you can compare them here if each quote uses the same type of rate.

What down payment and tenure do

Down payment. Since 25 May 2026, Central Bank of Sri Lanka rules mean you must pay at least 60% upfront for an unregistered car (or one registered for less than a year), and at least 40% for a car registered and used in Sri Lanka for more than a year. A larger down payment means a smaller loan, a lower EMI and less interest overall, so see our guide to car financing in Sri Lanka for the full rules.

Tenure. A longer period lowers the monthly payment but increases the total interest you pay. A shorter period costs more each month but less overall. The lender sets the longest period it will allow.

Worked example (illustrative only)

These figures are for illustration. 14% a year is an example rate, not a Waltex or bank offer.

A used car registered in Sri Lanka for more than a year, priced at LKR 5,000,000:

• Minimum down payment (40%): LKR 2,000,000
• Amount borrowed: LKR 3,000,000
• At an illustrative 14% a year over 60 months: EMI about LKR 69,805, total interest about LKR 1,188,285
• Over 48 months instead: EMI about LKR 81,979, total interest about LKR 935,013

For an unregistered new car at LKR 10,000,000, the minimum down payment is 60% (LKR 6,000,000). Borrowing the remaining LKR 4,000,000 at the same illustrative 14% over 60 months gives an EMI of about LKR 93,073.

Car loan and leasing calculator FAQs

How is car loan EMI calculated in Sri Lanka?

Most banks work out EMI on a reducing balance: EMI = P x r x (1 + r)^n / ((1 + r)^n - 1), where P is the amount borrowed, r is the yearly rate divided by 12 and by 100, and n is the number of months. Our calculator uses this formula.

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

Under Central Bank of Sri Lanka rules in force since 25 May 2026, lenders can finance up to 40% of the value of an unregistered car, or of a car registered for less than a year, so you pay at least 60%. For cars registered and used in Sri Lanka for more than a year, they can finance up to 60%, so you pay at least 40%.

Can I use this as a leasing calculator?

Yes, as an estimate. Enter the car price, your down payment, the leasing company's reducing-balance rate and the number of months. If a lease is quoted as a flat rate, ask for the equivalent reducing-balance rate first, because a flat rate costs more than the same number on a reducing balance.

What interest rate should I enter?

Use the rate from a quote you have received from a bank or leasing company. If you do not have one yet, try a few rates, for example 12%, 14% and 16% (illustrative only), to see how the monthly payment changes. Confirm the final rate with the lender.

How long can I take to repay a car loan or lease?

The lender sets the maximum period, and it can depend on the car's age and your income. A longer period lowers the monthly payment but increases the total interest. Try 36, 48 and 60 months in the calculator to compare.

Can I finance a used car?

Yes. Banks and leasing companies finance used cars, subject to their own checks. For a car already registered in Sri Lanka, the value used for the loan is usually based on a professional valuer's report, and the down payment rules above apply.

Is the calculator result a final offer?

No. It is an estimate to help you plan. It does not include fees, insurance or taxes, and the final rate, amount and terms are set by the lender.
