How we calculated this
The arithmetic behind your instalment, applied to the figures you entered.
1. The amount actually financed
The lender advances the vehicle price less your down payment.
- Vehicle price: LKR 0.00
- Down payment: − LKR 0.00
- Amount financed: LKR 0.00
2. Working out the instalment
On a flat rate, interest is charged on the full original amount for the entire term, regardless of how much you have already repaid. The total is then spread evenly across the instalments.
- Interest: LKR 0.00 × 0% × 5.00 years = LKR 0.00
- Instalment: (LKR 0.00 + LKR 0.00) ÷ 60 = LKR 0.00
3. The total you actually part with
- All instalments: LKR 0.00
- Of which interest: LKR 0.00
- Paid upfront: LKR 0.00
- Total: LKR 0.00
Calculation assumptions

Where the rules leave room for interpretation, this is the position we took. Open any one to see the reasoning.
Loans are calculated on a reducing-balance basisYou can change this
The loan calculator uses the standard annuity formula, where interest each period is charged on the outstanding balance. Some Sri Lankan leasing products quote a flat rate instead, which produces a higher effective cost for the same headline rate — switch the interest basis if your quote uses a flat rate.
Fees are paid upfront unless you say otherwiseYou can change this
Processing, documentation and insurance fees are treated as paid at the start and are not added to the financed amount, unless you choose to capitalise them.

Frequently asked questions
How is a vehicle lease payment calculated in Sri Lanka?
The leasing company finances the vehicle price less your down payment. Interest is applied to that financed amount — often as a flat rate, meaning interest is charged on the full original amount for the whole term — and the total is divided across the number of instalments. This calculator handles both flat and reducing-balance quotes.
Why is a leasing rate higher than it looks?
Most leasing quotes in Sri Lanka use a flat rate. Because interest is charged on the original amount rather than the falling balance, a flat rate costs substantially more than the same figure on a reducing balance — often close to double. The calculator shows the reducing-balance equivalent of your flat quote so you can compare it against a bank loan.
How much down payment do I need for a vehicle lease?
Leasing companies typically require a significant share of the vehicle price upfront, and loan-to-value limits on vehicle financing in Sri Lanka have changed several times in recent years. The exact requirement depends on the vehicle type and the current regulations, so confirm the figure with the lender rather than assuming.
What other costs come with leasing a vehicle?
Beyond the instalments there are documentation and processing fees, comprehensive insurance for the duration of the lease, registration and transfer costs, and often early-settlement charges if you want to close the facility ahead of schedule. Enter what you know in the upfront costs field to see the full picture.
Is leasing cheaper than a bank loan?
Not usually on rate alone, but leasing is often easier to obtain and faster to process. The way to compare them is total amount payable over the same term, using the reducing-balance equivalent of any flat quote — which is exactly what this calculator produces.
