A high credit score at 18 usually results from being an authorized user on a parent’s long-standing account, having a student loan with early on-time payments, or, rarely, a very short but flawless credit history. Age does not directly determine your score; rather, a high score indicates a history of responsible, on-time payments, even if that history is short.
For an 18-year-old, a "good" credit score is generally considered to be 670 or above (FICO), with the average score for 18-29 year olds often falling in the Good (670-739) or Fair (580-669) range, around 680, but even a score in the high 600s is great as it shows early financial responsibility and helps you qualify for better loan terms later.
A good credit score is 670 and up. According to Experian®, the average credit score for young adults ages 18-25 is 679, so any score above that is considered above average for the age group.
Gen Z typically has an average credit score of about 680, while millennials tend to have a slightly higher average near 690. Older consumers typically have better credit scores due to a longer credit history, which is a significant factor in credit score calculations.
Older Consumers Dominate the 800 Club
Among consumers with FICO® Scores of 800 or better in 2025, more than half (55.5%) are over the age of 60. Generation X alone accounts for about a quarter (24.3%) of those with exceptional credit.
While older models of credit scores used to go as high as 900, you can no longer achieve a 900 credit score. The highest score you can receive today is 850.
Yes, you can likely get a $50,000 loan with a 700 credit score, as this falls into the "good" credit range (670-739) that unlocks better rates, but approval also hinges on your income, debt-to-income (DTI) ratio (ideally below 36%), and overall credit history, with lenders looking for stability and repayment ability, so prequalifying with multiple lenders helps compare terms.
What is the average credit line for an 18-year-old? The average credit card limit for an 18-year-old is $12,899, according to Q3 2023 Experian data.
That said, you won't necessarily start with a specific score—everyone's situation is different, which gets reflected in your score. Regardless, you won't be starting at 0, nor will you be at the highest score.
In a 2019 study of people with a perfect 850 credit score, the average age of their oldest accounts was 30 years old according to FICO. So the older your length of credit history, the better the impact tends to be on your credit score.
For a score with a range of 300 to 850, a credit score of 670 to 739 is considered good. Credit scores of 740 and above are very good while 800 and higher are excellent. For credit scores that range from 300 to 850, a credit score in the mid to high 600s or above is generally considered good.
Here's how Americans' average debt breaks out by generation: Generation Z: $34,328. Millennials: $132,280. Generation X: $158,105.
A 524 credit score is not considered good according to some major credit scoring models. Lower credit scores may indicate higher risk for lenders, so this could lead to denial of credit or higher interest rates or less favorable terms if you do get approved.
It is rare to have an 850 credit score, but not impossible, and may be useful when applying for credit opportunities. Achieving and maintaining an 850 credit score can be difficult as it takes time, diligence and commitment to manage your credit effectively.
Pay your bills on time
Prioritize and schedule your monthly payments, making sure to pay at least the minimum payment on time every month on all your accounts. Try to pay more than what's due whenever possible. This helps to pay down debt faster, save on interest expense and may improve your credit score.
