October 20, 2022

Whether you are buying a car for personal use or business, it’s important to know how to calculate car loan interest Singapore. 

The joy of owning a vehicle is sadly accompanied by the pain of paying for it. This makes it crucial that you understand how to calculate car loan interest Singapore and how to access the best car loan deals.

However, you might be wondering about how to calculate car loan interest, loan tenure, and the amount you can access for a car loan. 

In this article, we will take a look at how to calculate car loan interest and all the factors you need to consider when selecting a car loan. 

Knowing how to calculate loan interest will allow you to compare budgets and car loan offers more effectively.

How Much Can You Borrow For A Car Loan?

The amount you can borrow is set at 60% or 70% of the open market value (OMV). 

If you want to get a car loan to purchase a vehicle with an OMV of $20,000, then you can get up to 70% of its value. If your car has an OMV of more than $20,000, you will receive 60% of its value.

Note that it’s not a guarantee that you will get the maximum amount. 

The amount you will get depends on other factors such as your monthly income, other debt obligations, and credit score. 

Lenders will have to check the total debt servicing ratio (TDSR), which is capped at 55%. This means your total monthly debt obligations should not exceed 55%.

Those with high obligations will not be able to access 60% or 70% of car loans from the bank. In addition to this, they will also need to raise the deposit of 30% for the car.

What Do COE, OMV, And PARF Mean?

A Certificate of Entitlement (COE) gives the right to own and use a car for 10 years in Singapore. 

Before you buy a car, you must bid for a COE based on the category of the car. The price of the COE depends on the number of bids submitted.

Below are the five categories.

  • Category A: Car with an engine capacity of 1600cc and a maximum power output of 97Kw. Also includes electric cars with a maximum output of 110kw
  • Category B: Cars with an engine capacity of over 1600cc and a maximum power output of 97Kw. electric cars with a maximum output of above 110 kW
  • Category C: Goods vehicles and buses
  • Category D: Motorcycles
  • Category E: Open, except for motorcycles

Open Market Value

The OMV of a car is the price you will pay for a vehicle imported into Singapore. This price is given by Singapore customs. 

It includes the purchase price, freight, insurance, and other car costs incurred during the delivery of the car to Singapore.

When buying a car, you will need to get the vehicle’s OMV so you can be able to calculate the upfront fees and the registration.


A Preferential Additional Registration Fee (PARF) is a rebate you enjoy when you de-register your car. You can enjoy the rebate if: 

  • The car is not more than 10 years old
  • You have a non-electric tax that is not more than eight years old
  • Electric cars registered after 15 Sep 2022 don’t opt in for the 10-year life span and are not more than  eight years old
  • Electric cars registered after 15 Sep 2022 opt in for the 10-year life span and are not more than 10 years old

The younger the car, the more rebates you are likely to get. The PARF rebate depends on the age of the car and its value.

Age of vehicle at de-registrationPARF rebate (COE May 2002 onwards)
Not exceeding 5 years75% of ARF paid
Above 5 years but not exceeding 6 years70% of ARF paid
Above 6 years but not exceeding 7 years65% of ARF paid
Above 7 years but not exceeding 8 years60% of ARF paid

How Long Should Your Car Loan Tenure Be?

The loan tenure of your car depends on your ability to repay the loan. Lenders offer up to seven years’ duration to clear the loan. However, you should note that the longer the loan tenure, the higher the cost of the loan.

There is no rule on the best tenure for a car loan; rather, it depends on your personal choices. The loan tenure determines the monthly payments. 

Pick a loan tenure that is manageable and ensure you don’t default on the loan.

Shorter loan tenures will have a high monthly repayment but are considered better because they reduce the total cost of the loan. So carefully choose a loan tenure that suits you.

In Singapore, an exception to the rule applies when you buy a second-hand car. 

Since you bid for a COE for 10 years, a car loan can only have a loan tenure of 10 years. What this means is that if you buy a six-year-old car, the loan tenure will be four years.

How To Use A Car Loan Calculator

It’s crucial to know how to calculate car loan interest as this enables you to make a more informed decision. 

The easiest way to calculate the monthly installment is by using a car loan calculator. Before calculating the monthly repayments, you will need the following parameters:

  • Cost of the car
  • Loan duration
  • The loan’s interest rate

The car loan calculator will work out the monthly installments for you. It will give you the following information: 

  • The total amount of interest paid

Interest paid is the total cost of the loan.

  • Total monthly repayments

This is the amount you will pay when you complete paying the loan.

Using the car loan calculator will help you compare the offers from various lenders, and you can choose the best one. 

So be sure to use the car loan calculator in Singapore after you get various quotes from various lenders.

How To Lower Your Car Loan Payment

A high car loan repayment affects your budget and may ruin your cashflow. Lowering your car loan payments will make it easy for you to repay the loan and avoid defaulting. 

Here is how to lower your car loan payment.

Negotiate For Lower Interest

The surest way to lower your car loan repayment is to negotiate for lower interest rates or select loans with lower interest rates. This way will ensure you get low loan repayments.

Choose A Car With A Lower Cost

You can get a lower loan repayment by choosing a car whose cost is lower. A lower cost means you will borrow less, and you can lower the loan payments.

Use Cash To Make A Higher Deposit

You can pay more in cash and reduce the amount you would like to borrow. If you opt to pay more in cash, your loan payment will be lower.

Choose A Shorter Loan Tenure

A shorter tenure reduces the interest you will pay. By opting for a shorter loan tenure, your equated monthly payments will be higher, but you will reduce the cost of the loan.

Refinance Your Car Loan

By refinancing, you are likely to get a lower interest rate, which will reduce the amount you pay for the car loan.

Make Extra Payments

If you get lucky and have extra money, pay off the car loan. This reduces the interest you will pay on the loan and, in turn, lowers the cost of the loan.
