What Colorado charges for vehicle registration and how to find your exact fee
Colorado registration fees depend on your vehicle's age, weight, and type — not on its value or condition. The state uses a depreciation schedule that assigns a taxable value to your vehicle based on the model year, then applies a flat fee per hundred dollars of that value. A 2024 sedan and a 2024 truck registered the same year will pay different amounts because they weigh differently. A 2015 sedan and a 2024 sedan will pay different amounts because of the depreciation schedule.
The Colorado Department of Revenue publishes the depreciation tables and fee rates each year on their website. You can calculate your fee by hand using those tables, or you can use the state's online fee calculator, which does the math for you. Either way, you need your vehicle's model year, gross vehicle weight rating (GVWR), and vehicle type classification.
Key Takeaways
- Colorado registration fees are based on a vehicle's model year and weight, not its purchase price or condition.
- The state publishes a depreciation schedule each year that assigns a taxable value to every model year; older vehicles have lower taxable values.
- You can calculate your fee using the Colorado Department of Revenue's online calculator or by looking up the depreciation table and fee rate yourself.
- Your vehicle's gross vehicle weight rating (GVWR) — found on the driver's door jamb or in your owner's manual — determines which weight class you fall into.
- Trailers, motorcycles, and commercial vehicles have separate fee structures and are not calculated the same way as passenger cars and light trucks.
Finding your vehicle's taxable value using the depreciation schedule
The Colorado Department of Revenue assigns a taxable value to each model year based on a depreciation curve. A 2024 vehicle starts at 100% of a baseline value; a 2023 vehicle is worth less; a 2015 vehicle is worth much less. The state recalculates these percentages every year, so the 2024 schedule is different from the 2023 schedule.
To find your vehicle's taxable value, you need the depreciation table for the current registration year. The Department of Revenue publishes this on their website under "Vehicle Registration Fees" or "Depreciation Schedule." Locate your model year in the table and note the percentage. Then multiply that percentage by the baseline value for your vehicle type. The result is your taxable value.
For example, if the 2020 depreciation percentage is 60% and the baseline value for a passenger car is $20,000, your 2020 car's taxable value would be $12,000. You do not need to know what you paid for the vehicle or what it is worth today — the state's schedule determines it.
How vehicle weight affects your registration fee
Colorado groups vehicles by gross vehicle weight rating (GVWR), which is the maximum weight the vehicle is designed to carry when fully loaded. This is not the vehicle's actual weight today; it is a manufacturer specification. You can find your GVWR on a label inside the driver's door jamb, in your owner's manual, or on your vehicle's title.
The state charges different fee rates for different weight classes. A passenger car with a GVWR under 6,000 pounds pays one rate per hundred dollars of taxable value. A light truck with a GVWR between 6,000 and 10,000 pounds pays a different rate. A heavier truck pays yet another rate. The fee rate is multiplied by your taxable value (divided by 100) to get your total fee.
This is why two vehicles registered in the same year can have very different fees. A 2024 sedan and a 2024 full-size pickup truck both depreciate at the same rate, but the truck's higher GVWR puts it in a higher fee bracket, so the truck costs more to register.
Using the Colorado Department of Revenue online calculator
The fastest way to find your exact fee is to use the state's online registration fee calculator. Go to the Colorado Department of Revenue website, navigate to the Vehicle Registration section, and look for "Calculate Registration Fees" or a similar link. Enter your vehicle's model year, GVWR, and vehicle type (passenger car, light truck, motorcycle, etc.), then click calculate.
The calculator returns your estimated fee for the current registration year. This is the amount you will owe when you renew or register your vehicle, before any local taxes, late fees, or title transfer charges. The calculator does not include county-specific fees, which vary by location, so your final bill may be slightly higher.
Keep in mind that the calculator shows the fee for the current year only. If you are calculating ahead for a future year, the depreciation schedule and fee rates may change, so the number will not be exact.
Calculating your fee by hand using the depreciation table and fee rate
If you prefer to do the math yourself or want to understand how the fee is calculated, follow these steps. First, find your vehicle's model year in the current depreciation schedule published by the Colorado Department of Revenue. Note the depreciation percentage. Second, find the baseline value for your vehicle type in the same document. Multiply the baseline value by the depreciation percentage to get your taxable value.
Third, find your vehicle's GVWR and locate the corresponding fee rate in the fee schedule. The fee rate is expressed as a dollar amount per $100 of taxable value. Divide your taxable value by 100, then multiply by the fee rate. The result is your registration fee.
Example: A 2020 passenger car with a GVWR of 4,500 pounds. The depreciation percentage for 2020 is 60%. The baseline value for a passenger car is $20,000. Taxable value = $20,000 × 0.60 = $12,000. The fee rate for a car under 6,000 pounds GVWR is $6.50 per $100. Fee = ($12,000 ÷ 100) × $6.50 = $780.
Special cases: motorcycles, trailers, and commercial vehicles
Motorcycles use a separate depreciation schedule and fee rate. The baseline value is lower, and the fee per $100 is different. Trailers are charged based on their unladen weight, not GVWR, and have their own fee structure. Commercial vehicles, including those registered for business use, may fall under a different fee schedule altogether.
If your vehicle does not fit the standard passenger car or light truck category, check the Colorado Department of Revenue website for the specific depreciation table and fee rate that applies to your vehicle type. The calculation method is the same, but the numbers are different.
What the registration fee does and does not include
The registration fee you calculate covers the cost of your license plate and registration certificate. It does not include a title transfer fee (charged if you are registering a vehicle for the first time in Colorado), a county-specific tax or fee (which varies by county), or late fees (charged if you renew after your registration expires).
Some counties in Colorado charge an additional local tax on vehicle registration. This is added to your state registration fee at the time of payment. The online calculator shows the state fee only; you will need to contact your county clerk's office or check their website to learn about your county charges an additional fee.
Frequently Asked Questions
Does the registration fee change every year?
Yes. The depreciation schedule and fee rates are recalculated annually by the Colorado Department of Revenue. A vehicle that costs $500 to register one year may cost $510 the next year, even if nothing about the vehicle changed, because the fee rates increased. The depreciation percentages also shift slightly each year.
Why does my truck cost more to register than my car if they are the same year?
Because your truck has a higher GVWR, which puts it in a higher fee bracket. Colorado charges a higher fee per $100 of taxable value for heavier vehicles. The truck's weight, not its value or condition, is what drives the higher cost.
Can I use last year's depreciation schedule to estimate this year's fee?
No. The depreciation percentages and fee rates change every year, so using an old schedule will give you an inaccurate number. Always use the current year's schedule, which the Colorado Department of Revenue publishes before the registration year begins.
Where do I find my vehicle's GVWR if I do not have the manual?
Check the label on the inside of the driver's door jamb — it usually lists GVWR along with tire pressure and other specifications. If that label is missing or unreadable, check your vehicle's title or registration documents, which may include the GVWR. You can also contact the vehicle manufacturer with your VIN.
Does the calculator include county fees?
No. The Colorado Department of Revenue calculator shows only the state registration fee. Some counties charge an additional local fee or tax. Contact your county clerk's office to find out whether your county charges an extra fee and what the amount is.
