The window sticker — officially called the Monroney label after Senator Mike Monroney, who sponsored the Automobile Information Disclosure Act of 1958 — is the only legally required pricing disclosure on every new car sold in the United States. The FTC enforces its accuracy. Yet most buyers glance at the big MSRP number at the bottom and ignore everything else. That's a mistake: the sticker tells you exactly what you're paying for, what the manufacturer charged the dealer, what the car's real fuel cost will be, and — critically — what items were added by the factory vs. what the dealer tacked on with a separate addendum sticker. Here's how to read every section.
Section 1: The Top Header — Vehicle Identification
The top of the sticker contains:
- Model Year, Make, Model, Trim: Verify this matches what you think you're buying. A "2026 Honda Accord EX" should say exactly that — not "2026 Honda Accord LX with EX package."
- VIN (Vehicle Identification Number): The 17-character VIN uniquely identifies this specific vehicle. Write it down or photograph it. The VIN encodes the manufacturer, model, engine type, restraint system, and production sequence. Use an online VIN decoder (NHTSA offers a free one) to verify the car's factory specifications match the sticker.
- Exterior/Interior Color, Engine, Transmission: Self-explanatory, but verify — especially if the dealer is locating the car from another lot.
Section 2: Standard Equipment (Included at No Extra Charge)
This section lists everything included in the base MSRP: engine, transmission, safety features (airbags, stability control, backup camera — all federally mandated), infotainment system, seating materials, and standard warranty. This is the car the manufacturer built before any options were added. It's useful for comparing trims: the difference in price between an LX and an EX should correspond directly to the additional equipment listed in each trim's "Standard Equipment" section.
Section 3: Optional Equipment and Packages
This is where costs multiply. Every option is listed with a price, grouped into categories:
- Factory-installed options: Items the manufacturer installs during production — upgraded audio systems, sunroofs, performance packages, towing packages. These are generally priced fairly relative to their actual cost and cannot be removed (the car was built with them).
- Port-installed options: Accessories installed at the port of entry or distribution center, not the factory — all-weather floor mats, roof racks, body-side moldings, cargo organizers. These often carry high markups (300-500%) for items you could buy aftermarket for much less. Example: $250 for "all-weather floor mats" that cost $80 on Amazon. If you don't want them, ask if they can be removed. Sometimes yes, sometimes no — the dealer may have already paid for them.
- Packages: Bundled options sold as a group (e.g., "Technology Package" or "Premium Package"). Packages generally offer a discount vs. buying each option separately — if you actually want everything in the package. If you only want the navigation system but not the sunroof, and they're bundled, you're paying for both. Compare the package price to the sum of its contents.
Section 4: Pricing Summary (The Block That Matters Most)
This is the most important section, typically on the right side of the sticker:
- Base MSRP: The price of the base vehicle with standard equipment.
- Options Total: The sum of all optional equipment and packages.
- Destination Charge: The fee for transporting the vehicle from the factory to the dealership. This is non-negotiable and the same for every buyer of that model — it's set by the manufacturer, not the dealer. For 2026, typical destination charges range from $1,095 (small cars) to $1,895 (large trucks/SUVs).
- Total MSRP: Base + Options + Destination. This is the manufacturer's suggested price — not what you should pay.
Section 5: Fuel Economy and Environmental Info
The EPA fuel economy label shows city, highway, and combined MPG, plus estimated annual fuel cost (based on 15,000 miles/year and current national average fuel prices). Also includes a greenhouse gas rating and smog rating. This section is useful but understand its assumptions: the annual fuel cost is based on national average prices — your actual cost depends on local fuel prices and your driving patterns. Use our Gas Cost Calculator to compute real fuel costs with your local prices and annual mileage.
Section 6: Safety Ratings
NHTSA crash test ratings (1-5 stars) for frontal crash, side crash, and rollover. Note: not all vehicles have been tested in every category. A blank field means "not tested," not "0 stars." IIHS ratings (Top Safety Pick, Top Safety Pick+) may be mentioned separately but are not required on the Monroney label — check IIHS.org independently.
Section 7: Parts Content and Final Assembly
Lists the percentage of parts sourced from the U.S./Canada, the country of origin for the engine and transmission, and the final assembly location. For EV buyers considering the federal tax credit, this section is relevant because the Inflation Reduction Act ties the $7,500 credit to North American assembly and battery component sourcing requirements. However, final eligibility is complex and depends on IRS guidance, not just the sticker.
The Addendum Sticker: Where Dealers Inflate Prices
Next to the Monroney label, many dealers affix a second sticker — the dealer addendum — listing items the dealer (not the manufacturer) has added to the car. Common addendum items include:
- Paint protection / "ceramic coating" — typically $500-1,500 for a product that costs the dealer $30-100.
- Fabric protection / "Scotchgard" — $300-500 for a $15 spray can application.
- VIN etching on windows — $200-400 for something insurance companies rarely require and that provides negligible theft deterrence.
- Nitrogen tire fill — $100-200 for air that's 78% nitrogen naturally (regular air is 78% nitrogen).
- Door edge guards / body-side moldings — $300-600 for $50 in parts.
- Dealer-installed accessories (running boards, bed liners, etc.) — often priced at 2-3x aftermarket cost.
All items on a dealer addendum sticker are negotiable — and most should be refused entirely. The dealer has already inflated the car's price by thousands of dollars through these additions. Tell the salesperson: "I'm only paying for items on the factory Monroney label. Please remove or credit all addendum items." If they refuse, find another dealer — almost every brand has multiple dealerships within driving distance. For more tactics on this conversation, see our Car Loan Negotiation guide.
How to Use the Sticker to Spot Dealer Tricks
- Compare the sticker to the dealer's website listing. If the website shows a different MSRP, they've already added dealer markup or accessories — the Monroney label is the legal baseline.
- Check the options list against your needs. Dealers order cars loaded with high-margin options because those options increase the sale price. If a car has $4,000 in port-installed accessories (roof rack, cargo tray, all-weather mats, door sill plates), that's $4,000 you're paying for items you may not want.
- Calculate the "real" price you should target. Use the invoice price (available from Edmunds or TrueCar) minus holdback plus fair profit minus manufacturer incentives — the formula detailed in our Incentives vs Dealer Discounts guide.
- Photograph the sticker. It's your evidence if the dealer later tries to claim different pricing or equipment. It's also useful for insurance and registration purposes.
Window Sticker for Used Cars: The Buyer's Guide
Used cars don't have Monroney labels, but the FTC requires dealers to display a Buyer's Guide on every used car. This is not the same thing. The Buyer's Guide must disclose: whether the car is sold "as is" or with a warranty, the warranty terms if applicable, the percentage of repair costs the dealer will pay under warranty, and a warning to get all promises in writing. The Buyer's Guide also advises you to get an independent mechanical inspection before purchasing — advice you should follow.
For a used car, request the original window sticker from the dealer if available (some dealers keep them), or look up the original MSRP and equipment using the VIN on MonroneyLabel.com or similar services. This tells you what the car originally sold for and what equipment was factory-installed — useful context for negotiating a fair used price.

The Dealer Addendum Sticker: A Deeper Dive into Dealer Profit Tactics
Beyond the common add-ons covered above, some dealers have evolved more sophisticated addendum strategies. "Market adjustment" is a line item that's essentially pure additional dealer profit — often framed as "due to high demand and limited supply." In 2021-2022, market adjustments of $5,000-20,000 were common on popular models. By mid-2026, the practice has receded on most mass-market vehicles but persists on limited-production or high-demand models (Toyota Grand Highlander, Ford Maverick, certain hybrid trims). A market adjustment is 100% negotiable — and in a normalizing market, you should refuse to pay any dealer markup above MSRP. If the dealer insists, find another dealer. The car market is large enough that there's almost always a dealer willing to sell at MSRP or below. Another addendum item to scrutinize: "dealer-installed security system" or "theft deterrent package." These are typically aftermarket alarm systems or GPS trackers priced at $600-1,200 that duplicate the factory security features already built into the car. Modern vehicles have engine immobilizers, alarm systems, and (on many models) built-in telematics that can track the vehicle's location. The dealer's add-on security system provides negligible additional protection and primarily serves as a profit center. Refuse it.
How to Photograph and Document the Sticker for Negotiation and Records
Before you start negotiating, take clear, well-lit photographs of both the Monroney label and any dealer addendum sticker. Modern smartphone cameras are sufficient — make sure the VIN, MSRP breakdown, options list, and total price are legible. These photographs serve four purposes: (1) Negotiation record: If the salesperson quotes a different MSRP than what's on the sticker, you have evidence. (2) Insurance documentation: Your insurer needs the MSRP and factory-installed options to set appropriate coverage. The sticker is the definitive source. (3) Resale documentation: When you sell the car privately, showing the original window sticker (with factory options) increases buyer confidence and supports a higher asking price. (4) Warranty verification: If a dealer later claims a feature was dealer-installed (not factory) and not covered by the manufacturer warranty, the Monroney label is your proof of factory installation. Store these photos with your vehicle records — they're worth money at resale time.
