When it comes to car loans, capital can save you thousands of people on interest costs.
Do I need to buy a car before my car rates go into effect?
President Donald Trump has announced 25% tariffs on imported cars and major auto parts. This makes sense for consumers and automakers.
- In 2025, new cars reached record numbers.
- While average monthly car payments are also increasing, you can use the “20% rule” to reduce your payments.
- Auto loan interest costs thousands of dollars to car buyers, depending on the structure of the funding transaction.
Buying a car is one of the biggest purchases that many Americans make in their lives. According to the Kelley Blue Book, the new car prices are record highs, with average prices creeping up to nearly $50,000 in 2025.
If you are purchasing a new car in 2025, choosing the right funding strategy can have a significant impact on ownership experience and monthly payments. What is the “20% rule”? Also, how can you use it to your advantage when purchasing a dream car, truck or SUV?
What is the 20% rule for car loans?
Thousands of drivers will fund new cars in 2025. The way you build a funding plan affects stocks in your new vehicle and monthly, annual and total payments, including interest.

A 20% minimum down payment can make the car buyer’s long-term financing transactions cheaper. According to Chase Bank, the down payment “reduces major loan amounts and interest you are likely to pay.”
Suppose you are funding the new 2025 Toyota RAV4. If you secure a 60-month (5-year) funding loan at a 4.99% interest rate, your monthly payments could drop by 20% to $440 a month (before taxes, fees and interest). The 2025 RAV4 20% down payment ($29,2590 before taxes and fees) is $5,850. This leaves 80% of the SUV’s MSRP principal ($23,400 in taxes, fees, interest).
Your monthly payment divides your principal loan amount by your loan period (60 months in the example above) and the monthly interest cost of the principal (4.99% in the example above). Drivers can save thousands of interest payments by saving at least 20% of the total interest costs as a down payment for expenses over time.
How to reduce interest costs on car loans
If you can save even more money with a car loan and manage your monthly payments after a 20% down payment, there is a way to pay the full cost of financing your car before the loan term ends. That being said, there may be costs associated with paying your car loan early, which can negatively affect your credit score.

If you pay the monthly loan amount and make an additional payment to your principal, you can repay the vehicle before the end of the loan term. This will reduce the amount of total interest you pay through funding, but can have unintended consequences depending on the lender.
Ultimately, the best way to guarantee that you save money on interest when funding your vehicle is to allow for the maximum down payment and gain more equity for your vehicle. The “20% Rule” is a strategy implemented to reduce the total cost of financing a vehicle, but it allows you to adjust your funding agreement to suit your individual financial needs and goals.
What is the average monthly car payment?
According to consumer credit reporting firm Experian, the average car loan payment was “$675 as of the first quarter of 2025.” According to Nerdwallet, the average annual interest rate for individuals with a credit score of 661-780 is 6.70%. Interest rates for drivers with low credit scores (13.22% with a 501-600 score) increase significantly.
Between rising new car prices and high interest rates, raising new cars is more expensive than ever. Before purchasing a new car, truck or SUV, the driver should:
- Evaluate the amounts that the true cost of a new vehicle can include taxes, fees and interest
- Calculate your exact monthly car loan payments and see if it fits within your budget
- Think about how a high percentage of down payment can reduce your total funding expenditure
Brand new cars may be fun to own and drive, but used cars offer plenty of value for more affordable prices, so they are rarely needed. Thanks to depreciation, American drivers can find large deals on used car models that cost thousands of more than new ones. So if you’re in the market for new cars in 2025, be sure to check the numbers three times before making any financial commitments.
