A recent viral TikTok video from @caredge has revealed a hidden car-buying tactic that could be costing buyers thousands of dollars without them realizing it. The video dives into the concept of buy rate vs. sell rate, a hidden markup car dealers often use to increase their profit. In some cases, this markup can result in an additional $1,800 in interest for unsuspecting buyers. Understanding this trick is essential for making an informed purchase in today’s competitive car market.

What Is the Buy Rate vs. Sell Rate?
When purchasing a vehicle, dealers offer financing options that may not always be as straightforward as they seem. The “buy rate” is the interest rate the dealer receives from the bank or lender, while the “sell rate” is the higher rate the dealer passes on to the buyer. Dealers often mark up the sale price, which leads to higher monthly payments and more interest paid over time.
In the TikTok video, @caredge’s expert explains how, by simply asking for the buy rate, buyers can often avoid paying this hidden markup. If you’re financing a car, understanding the difference between these rates could save you hundreds or even thousands of dollars in interest.
Why It Matters More Than Ever in 2026
As we head into 2026, the car-buying process is becoming even more complex. With car prices rising, interest rates fluctuating, and dealerships looking for ways to maximize profit, buyers must be more vigilant than ever. Knowing the buy rate and sell rate difference allows buyers to push back on unnecessary costs and negotiate more favorable terms.

The video highlights the importance of doing your homework before committing to a loan. When you’re prepared and ask the right questions, such as requesting the buy rate, you’ll have a much clearer understanding of the terms and can avoid falling into a hidden markup trap.
Key Steps to Avoid Overpaying for a Car
Here are the essential tips to avoid paying more than you should:
- Ask for the Buy Rate: Always request the buy rate from the dealership’s finance office. This ensures you know the base interest rate before the dealership marks it up.
- Shop Around for Financing: Don’t settle for the dealership’s financing options. Compare offers from banks or credit unions to secure the best interest rate. You can check out more financing tips in our article on car buying strategies.
- Know Your Credit Score: The better your credit score, the more leverage you’ll have to negotiate lower interest rates. Check your score before heading to the dealership to ensure you’re getting the best deal.
Why This Is a Major Issue for Car Buyers
The hidden markup is a significant issue because it is not always obvious to buyers. Dealerships may present the deal as a good one, but the interest rate might be marked up without clear disclosure. By the time buyers realize the cost, it’s often too late to change the terms. This is why transparency and preparation are critical for car buyers in 2026.
Avoid Hidden Fees: Ask for a Breakdown of All Costs
Beyond the buy rate, it’s also important to ask for a full breakdown of the total cost of your car purchase. This includes understanding all fees, taxes, and additional costs that may not be clearly listed. By being proactive and asking for clarity, you can ensure you’re not blindsided by hidden charges.
