Understanding PQP: Prevailing Quota Premium Explained
What Is the Prevailing Quota Premium (PQP)?
The Prevailing Quota Premium, universally abbreviated as PQP, is the price you pay to renew your Certificate of Entitlement when your vehicle's original 10-year COE expires. Unlike the quota premium (QP) that is determined through competitive bidding, the PQP is an administratively set price calculated as the moving average of COE quota premiums over the preceding three months. This means you do not need to participate in an auction to renew your COE; you simply pay the current PQP for your vehicle's category.
The PQP is one of the most important numbers in Singapore's car ownership landscape. It determines how much an owner must pay to keep their vehicle on the road beyond the initial 10-year period, and it directly influences the economics of the PARF car versus COE car decision. When PQP is high, renewal is expensive, and more owners may choose to deregister instead. When PQP is low, renewal becomes attractive, and fewer vehicles leave the road.
You can track current PQP values for all categories on our PQP page.
How PQP Is Calculated
The PQP formula is straightforward in concept: it is the simple arithmetic average of all quota premiums from COE bidding exercises conducted in the three months immediately preceding the current month. Since there are typically two bidding exercises per month, the PQP for any given month is based on approximately six data points (two per month over three months).
The Formula
PQP = (Sum of all QPs in the preceding 3 months) / (Number of bidding exercises in those 3 months)
For example, if Category A had the following quota premiums over the past three months:
| Month | Exercise | Quota Premium |
|---|---|---|
| January | 1st | $106,000 |
| January | 2nd | $108,000 |
| February | 1st | $110,000 |
| February | 2nd | $107,000 |
| March | 1st | $112,000 |
| March | 2nd | $109,000 |
The PQP for April would be: ($106,000 + $108,000 + $110,000 + $107,000 + $112,000 + $109,000) / 6 = $108,667
This averaging mechanism smooths out the volatility inherent in individual bidding exercises. A single exercise can produce an unusually high or low QP due to temporary demand spikes or supply fluctuations, but the three-month average dampens these outliers.
When Is PQP Updated?
The PQP is recalculated at the start of each month based on the completed bidding exercises from the preceding three calendar months. LTA publishes the updated PQP values on the OneMotoring website. Because the calculation window moves forward each month, the PQP changes monthly, sometimes by small amounts and sometimes by several thousand dollars depending on market conditions.
PQP vs QP: Understanding the Difference
New buyers and those approaching their COE expiry often confuse the PQP and QP. While related, they serve very different purposes.
| Feature | Quota Premium (QP) | Prevailing Quota Premium (PQP) |
|---|---|---|
| Purpose | Price for a new COE | Price for renewing an existing COE |
| How determined | Competitive auction (lowest successful bid) | 3-month moving average of QPs |
| When paid | When registering a new vehicle | When renewing COE at the 10-year mark |
| Volatility | Can swing significantly between exercises | Smoother due to averaging |
| PARF eligibility | Vehicle retains PARF eligibility | No PARF eligibility after renewal |
The key practical difference: QP is what you pay to put a new car on the road; PQP is what you pay to keep an old car on the road. Because PQP is an average, it lags behind sudden QP movements. If COE prices spike in a single month, the PQP will rise more gradually over the following months. Conversely, if prices drop sharply, the PQP takes time to reflect the decline.
Renewing Your COE Using PQP
When your vehicle's 10-year COE is approaching expiry, you must decide whether to renew, deregister, or export. If you choose to renew, here is what you need to know:
5-Year vs 10-Year Renewal
You can renew your COE for either 5 years or 10 years. The cost is:
- 10-year renewal: Full PQP amount
- 5-year renewal: 50% of the PQP amount
A 10-year renewal gives you more flexibility and better resale value, since a potential buyer sees a longer remaining COE. A 5-year renewal has a lower upfront cost but limits your options. You cannot extend a 5-year renewal to 10 years later; once the 5-year period expires, you must renew again at the then-current PQP or deregister.
Timing Your Renewal
Because PQP changes monthly, the timing of your renewal can save or cost you thousands of dollars. If COE prices are trending upward, renewing sooner rather than later locks in a lower PQP. If prices are declining, waiting a month or two could result in a lower renewal cost. However, this is inherently speculative, and predicting short-term COE price movements is notoriously difficult.
LTA allows you to renew your COE up to three months before the expiry date. This gives you a window to monitor PQP trends and choose a favourable month. Our Results Archive and Trends page can help you spot directional changes in COE premiums.
What You Lose Upon Renewal
Renewing your COE at the PQP means forfeiting the vehicle's PARF eligibility. This is a one-way door: once renewed, the vehicle will never again qualify for a PARF rebate. The only financial recovery available upon subsequent deregistration is the pro-rated COE rebate based on remaining COE validity. For vehicles with a high original ARF, this forfeiture can represent a significant loss. Use our PARF Rebate Calculator to quantify what you would be giving up, and our Renew vs Scrap Calculator to compare the financial outcomes.
Historical PQP Trends
PQP values have fluctuated enormously over the past two decades, reflecting the broader trajectory of COE prices. During the 2013 peak, Category A PQP exceeded $80,000, making renewal prohibitively expensive for many owners. Prices then fell significantly between 2014 and 2017 as the large cohort of vehicles registered during the 2002 to 2005 boom reached their 10-year expiry and flooded the market with replacement COEs.
From 2021 onward, COE prices began climbing again, driven by pandemic-era supply chain disruptions, a backlog of unregistered vehicles, and strong consumer demand. By 2023, Category A COE premiums had surpassed $100,000 for the first time, and PQP values followed suit. In 2026, PQP values remain elevated across all categories.
The cyclical nature of PQP is driven by the same factors that drive COE supply: vehicle growth rates, deregistration volumes, and quota adjustments. Understanding these cycles is valuable for long-term planning. Visit our Trends page for historical charts and analysis.
Strategic Considerations
When Renewal Makes Sense
- The vehicle is in good mechanical condition and has been well maintained.
- You are comfortable with the ongoing maintenance costs of an older vehicle.
- The PQP is lower than expected, making renewal a relative bargain.
- You want to minimise annual depreciation and overall cost of ownership.
- You do not need the latest features, safety technology, or fuel efficiency.
When Deregistration Makes More Sense
- The vehicle has significant mechanical issues that would be expensive to repair.
- The PQP is very high, making the renewal cost hard to justify for an ageing vehicle.
- The PARF rebate is substantial (for vehicles under 10 years being scrapped early).
- You want a newer vehicle with modern safety features and better fuel economy.
- The total cost of renewal plus expected maintenance exceeds the cost of buying a new or newer used car when annualised.
Frequently Asked Questions
Can I negotiate the PQP or get a discount on renewal?No. The PQP is a fixed, administratively determined price published by LTA. There is no negotiation, discount, or alternative pricing. Every vehicle owner renewing in the same category during the same month pays the same PQP. The only way to pay a different amount is to wait for a month when the PQP has changed.
What happens if I cannot afford the PQP when my COE expires?If you cannot afford to renew, you must deregister the vehicle before the COE expiry date. Deregistration entitles you to any applicable PARF rebate (if within the first 10 years) and a pro-rated COE rebate. These rebates are paid to you and can help fund a replacement vehicle or other needs. If you do nothing, the vehicle becomes illegal to operate, and LTA will take enforcement action.
Does the PQP differ by COE category?Yes. The PQP is calculated separately for each of the five COE categories (A, B, C, D, E). Each category has its own bidding exercises and quota premiums, so the three-month average is category-specific. Category A and B PQPs are typically the highest, while Category C and D PQPs are significantly lower. You must renew at the PQP for the category under which your vehicle is registered.
If I renew for 5 years, can I extend it to 10 years later?No. A 5-year renewal cannot be converted or extended to a 10-year renewal mid-term. When the 5-year renewed COE expires, you face the same three choices: renew again at the then-current PQP (for another 5 or 10 years), deregister, or export. Each renewal is an independent transaction at the prevailing rate at that time.
How do I find the current PQP for my category?Current PQP values are published on the LTA OneMotoring website and updated at the start of each month. COEkaki also tracks PQP values on our dedicated PQP page, along with historical data and trend charts to help you understand the direction of PQP movements for your category.
