Interest rates don’t stay the same forever. If you look back far enough, you’ll see that borrowing costs rise, fall, and sometimes swing dramatically. While no one can predict exactly where rates are headed next, history shows one clear pattern: over a 10-year period, interest rates almost always change — often by a lot.
Another long-term trend is how rates differ by loan type. Mortgages usually have the lowest interest rates, credit cards have the highest, and auto loans fall somewhere in between. Understanding why this happens can help you make smarter money decisions, especially when borrowing large amounts.
Below is a simple breakdown of how interest rates for major loans have changed over time — and what that means for everyday Americans.
Quick Snapshot: Key Interest Rate Trends
-
Mortgage rates have ranged from extremely high to historically low. They peaked at 18.45% in 1981, dropped to a record low of 2.65% in 2021, and then climbed again to 8.01% in late 2023. By the second quarter of 2024, average 30-year fixed rates were around 6.95%.
-
Credit card interest rates have steadily moved upward over the past decade. Rates hit a low of 12.74% in 2014 and climbed to a record high of 22.76% in Q2 2024.
-
Auto loan rates have seen moderate ups and downs. New car loan rates (48-month terms) were as high as 17.36% in 1981, fell to 4.00% in 2015, and rose again to about 8.65% by May 2024.
Why Mortgage Rates Tend to Be the Lowest
Mortgage rates have changed dramatically over the past 50 years. Data from Freddie Mac shows that the period from 2012 to 2022 was unusually favorable for homebuyers. During that entire decade, the average interest rate on a 30-year fixed mortgage stayed below 5% — something that had never happened before.
That era ended as inflation surged in the early 2020s. After hitting a historic low in early 2021, mortgage rates began rising quickly. By October 2023, they reached their highest point in more than two decades.
Even so, today’s rates still look reasonable when compared to earlier generations. From the early 1970s through the early 2000s, mortgage rates never fell below 6%, and during the 1980s, double-digit rates were common for over a decade.
Real-life example:
If your parents bought a home in the early 1980s, they may have paid interest rates well above 10%. By comparison, today’s 6–7% rates feel expensive — but historically, they’re not unusual.
Credit Card Interest Rates: High and Hard to Escape
Credit card interest rates behave differently from mortgage rates. Since the Federal Reserve began tracking them in the mid-1990s, card rates have stayed consistently high, with much smaller fluctuations.
The lowest recorded average was just under 12% in 2003. Fast forward to today, and average credit card rates are over 22% — the highest level ever recorded.
Unlike mortgages, credit card rates are unlikely to drop quickly. One reason is that Americans continue to carry record-high credit card balances, even as interest rates rise. Another reason is that credit cards don’t benefit from government programs designed to lower borrowing costs.
Most credit card rates are tied to the prime rate, so if the Federal Reserve eventually lowers rates, card interest rates may ease — but history suggests they’ll remain much higher than other types of loans.
Real-life example:
If you carry a $5,000 balance at a 22% interest rate and only make minimum payments, you could stay in debt for years and pay thousands in interest alone.
Auto Loan Rates: Middle of the Road, but Rising
Auto loan interest rates fall between mortgages and credit cards in terms of cost and volatility. They’ve changed more than credit card rates but far less than mortgage rates.
For decades, rates on standard 48-month new car loans hovered between 4% and 6%. That trend held from 2012 through most of 2022. Since then, rates have climbed sharply, reaching 8.65% by mid-2024.
However, most buyers today don’t choose 48-month loans. The average new car loan now stretches to about 68 months, which changes the interest picture.
-
60-month loans stayed under 6% for more than a decade but rose to about 8.20% in Q2 2024.
-
72-month loans, once comfortably below 6%, climbed to around 8.32% during the same period.
Longer loan terms lower your monthly payment — but they also increase the total interest you pay over time.
Why Interest Rates Vary So Much by Loan Type
The biggest reason interest rates differ is risk.
Credit Cards: Highest Risk, Highest Rates
Credit cards are unsecured loans. There’s no house or car backing them up. If someone stops paying, the lender can’t repossess an asset — they can only pursue collections. Because defaults are more common, lenders charge higher interest to offset those losses.
Auto and Mortgage Loans: Lower Risk
Car loans and mortgages are secured by physical assets. If payments stop, the lender can repossess the car or foreclose on the home. That reduces risk, allowing lenders to offer lower interest rates.
Another important factor is securitization. Mortgages and auto loans are often bundled and sold to investors, shifting some risk away from lenders. Credit card balances are securitized far less often.
Mortgages also benefit from government-backed programs through Fannie Mae and Freddie Mac, which help stabilize the housing market and keep borrowing costs lower for qualified buyers.
FAQs About Interest Rates
Does the Federal Reserve set my interest rate?
No — but it strongly influences them. The Fed controls the federal funds rate, which affects borrowing costs across the economy. When the Fed raises rates, loan interest rates usually rise. When it cuts rates, borrowing becomes cheaper.
Does my credit score matter?
Absolutely. A higher credit score signals lower risk to lenders, which usually means lower interest rates. Borrowers with poor credit often face much higher rates — or fewer loan options.
How do rising rates affect buying a home or car?
Higher interest rates mean higher monthly payments and less money going toward the loan balance. This can reduce how much home or car you can afford and may even affect loan approval.
The Bottom Line
Interest rates on mortgages and auto loans have risen in recent years, but they’re still moderate when viewed through a long-term historical lens. Credit card interest rates, on the other hand, remain extremely high and have consistently been the most expensive way to borrow money.
Understanding how rates differ — and why — can help you avoid costly debt, choose the right loan at the right time, and build healthier financial habits over the long run.
