COE Renewal Calculator
User Guide
Everything you need to know about calculating your COE renewal cost, monthly instalments, and down payment using the COEPLUS.COM calculator.
The COEPLUS.COM COE Renewal Calculator helps Singapore car owners estimate the total cost of renewing their Certificate of Entitlement (COE) and the monthly loan repayments. It is free to use, requires no registration, and is updated automatically with the latest PQP (Prevailing Quota Premium) figures from the Land Transport Authority (LTA).
This guide covers every field in the calculator, explains how to read the results, and provides worked examples so you can make a fully informed decision about your COE renewal.
What's New in Version 2.0.0
Version 2.0.0 introduces a more intuitive and flexible way to plan your COE renewal financing. The key change is the replacement of the Loan Percentage (%) input with a direct Loan Amount (S$) input, giving you precise control over how much you wish to borrow.
| Feature | v1.x (Previous) | v2.0.0 (Current) |
|---|---|---|
| Loan input | Loan % (e.g. 70%) | Loan Amount in S$ (e.g. S$83,602) |
| Default loan value | 70% of COE cost | Full COE cost (100% loan) |
| Down Payment display | Shown as % only | Shown as S$ amount and % |
| PQP source | Hardcoded figures | Auto-fetched from LTA via data.gov.sg |
| Admin PQP management | Not available | Full admin panel to update PQP |
Calculator Fields
The calculator has five input fields. Here is a detailed explanation of each one.
Select the category that matches your vehicle. The calculator supports four categories for car and commercial vehicle COE renewals.
| Category | Vehicle Type | Typical PQP Range |
|---|---|---|
| Cat A | Cars up to 1,600cc or 97kW (incl. most EVs) | S$100,000 – S$130,000 |
| Cat B | Cars above 1,600cc or 97kW | S$100,000 – S$135,000 |
| Cat C | Goods vehicles and buses | S$70,000 – S$90,000 |
| Cat E | Open category (any vehicle) | S$110,000 – S$135,000 |
Category D not included
Category D (Motorcycles) is not included in this calculator. The COEPLUS.COM service focuses on car and commercial vehicle COE renewals.
The Current PQP display below the category selector shows the Prevailing Quota Premium for your selected category — this is the reference price used for all calculations, fetched automatically from LTA.
Choose between a 5-year or 10-year COE renewal.
A 10-year renewal costs the full PQP amount. A 5-year renewal costs 50% of the PQP — half the price, but your COE expires sooner. The calculator automatically adjusts all figures when you switch between terms.
Which term should I choose?
Choose 10 years if you plan to keep the car long-term and want lower monthly payments. Choose 5 years if you want flexibility or expect to switch vehicles sooner. See the FAQ section for a detailed comparison.
This is the amount you wish to borrow from a bank or financial institution to finance your COE renewal.
Key points:
- The default value is the full COE cost (100% loan, S$0 down payment) — this is the starting point. Most users will reduce this figure.
- You can enter any amount from S$0 to the full COE cost.
- S$0 means you are paying entirely in cash (no loan).
- The field updates automatically when you change the category or renewal term.
Example
If the Cat A PQP is S$119,432 and you want to borrow S$80,000: type 80000 in the Loan Amount field. Down Payment = S$119,432 − S$80,000 = S$39,432 (33% of COE cost).
Enter the annual interest rate offered by your bank or financial institution. The default rate is 2.48% p.a., which is a typical market rate for COE renewal loans in Singapore.
Shop around
Rates can vary between 1.8% and 4.5% depending on the lender and your credit profile. Even a 0.5% difference can save you thousands of dollars over a 7-year loan tenure. COEPLUS.COM can help you compare rates from multiple banks — for free.
Enter the number of years over which you will repay the loan. The maximum tenure is 10 years (for a 10-year COE renewal) or 5 years (for a 5-year renewal).
A longer tenure means lower monthly instalments but higher total interest paid. A shorter tenure means higher monthly payments but less interest overall.
Reading the Results
After clicking "Calculate My COE Renewal Cost", the results panel shows six figures. Here is what each one means.
| Result Field | What It Means | Formula |
|---|---|---|
| COE Renewal Cost | Total COE cost for your selected term | PQP × 1.0 (10yr) or PQP × 0.5 (5yr) |
| Loan Amount | The exact amount you are borrowing (as entered) | As entered by you |
| Down Payment | Cash you pay upfront, shown in S$ and as a % | COE Cost − Loan Amount |
| Monthly Instalment | Estimated monthly repayment | Based on loan amount, rate, and tenure |
| Total Interest | Total interest paid over the full loan tenure | Monthly Instalment × Months − Loan Amount |
| Total Repayment | Total amount you will pay back to the bank | Loan Amount + Total Interest |
These are estimates
All figures are estimates based on current PQP rates and a standard flat-rate loan calculation. Actual figures depend on your lender's specific terms, processing fees, and repayment structure. Always confirm with your bank or financial institution before committing.

Understanding PQP
The Prevailing Quota Premium (PQP) is the rolling 3-month average of the Quota Premium (QP) from the most recent COE bidding exercises. It is set by the Land Transport Authority (LTA) and is updated monthly.
The PQP is the price you pay when renewing your COE — it is not the same as the latest bidding price. The PQP is typically more stable than the bidding price, which fluctuates with each exercise.
| Term | Definition | Used for |
|---|---|---|
| QP (Quota Premium) | The price at which the last successful bid was made in a specific bidding exercise | New vehicle purchases with COE |
| PQP (Prevailing Quota Premium) | 3-month moving average of the QP from the last three bidding exercises | COE renewal calculations |
The COEPLUS.COM calculator automatically fetches the latest PQP from the LTA dataset on data.gov.sg, so the figures you see are always current. There may be a short delay of up to 24 hours after LTA publishes new data before it appears in the calculator.
Frequently Asked Questions
Choose 5 years if: your car is ageing and may need significant repairs soon, you are considering switching to an EV in the next few years, or you prefer lower total commitment.
Choose 10 years if: your car is in good condition, you plan to keep it long-term, and you want lower monthly instalments spread over a longer period. A 10-year renewal also locks in today's PQP, which can be advantageous if prices are expected to rise.
