The average American carries $104,755 in total debt, according to Experian's most recent consumer debt study. But that single figure hides a life-cycle pattern that matters far more than the average: debt climbs steeply through your thirties, peaks in your late forties and fifties, then falls by roughly half by retirement.
Here's how much debt each age group actually carries, what it's made of, and how to tell whether yours is a problem.
Average total debt by generation
| Generation | Age range | Average total debt |
|---|---|---|
| Generation Z | 18–28 | $34,328 |
| Millennials | 29–44 | $132,280 |
| Generation X | 45–60 | $158,105 |
| Baby Boomers | 61–79 | $92,619 |
| Silent Generation | 80+ | $38,460 |
| All consumers | — | $104,755 |

Gen X carries the heaviest load — nearly 5× what Gen Z owes. That's not recklessness; it's timing. Gen X is the generation most likely to be simultaneously paying a mortgage near its peak balance, financing cars for a household of drivers, carrying leftover student loans, and in many cases co-signing for their kids.
Average debt by type and generation
Total debt is mostly one thing — a mortgage — so the type-level breakdown is where the useful detail lives:
| Debt type | Gen Z | Millennials | Gen X | Boomers | Silent |
|---|---|---|---|---|---|
| Mortgage | $262,004 | $320,027 | $286,574 | $196,227 | $148,514 |
| Student loan | $21,670 | $32,911 | $38,426 | $39,870 | $31,153 |
| Auto loan | $20,893 | $25,307 | $27,836 | $22,583 | $17,180 |
| Personal loan | $9,466 | $16,882 | $21,910 | $21,972 | $17,786 |
| Credit card | $3,493 | $6,961 | $9,600 | $6,795 | $3,445 |
Three things stand out:
Millennials have the largest mortgages at $320,027 on average. They're buying at today's prices with today's rates, so their balances start higher than any generation before them — even though Gen X owns more home equity.
Student loan balances go up with age. Boomers average $39,870, more than Gen Z's $21,670. Interest capitalization, income-driven repayment plans that don't cover accruing interest, and parent PLUS loans mean this debt often grows rather than shrinks.
Credit card debt peaks with Gen X at $9,600. This is the number to watch. Unlike a mortgage, credit card debt buys no asset — at typical rates above 20%, a $9,600 balance costs roughly $2,000 a year just to carry.
Not all debt is the same
The headline number treats a $300,000 mortgage and a $9,000 credit card balance as the same thing. They aren't:
- Debt that buys an appreciating asset — a mortgage on a home you can afford, a student loan that raised your earning power. These show up on both sides of your balance sheet.
- Debt that buys a depreciating asset — an auto loan. Neutral at best, and easy to overdo.
- Debt that buys nothing — credit card balances, personal loans used for consumption. Pure drag.
This is exactly why net worth, not debt, is the right scoreboard. A household with a $400,000 mortgage against a $600,000 house is in better shape than one with $15,000 in credit card debt and no assets — even though the first has 26× more debt.
How to tell if your debt is a problem
Two ratios do most of the work:
Debt-to-income (DTI). Total monthly debt payments divided by gross monthly income. Under 36% is healthy; lenders start balking above 43%.
Non-mortgage debt to income. Add up everything except your mortgage. If it exceeds 20% of gross income, it's crowding out saving.
If you're above either line, the standard playbook still works: cover minimums everywhere, then throw everything extra at the highest-rate balance — almost always a credit card — until it's gone.
The number that actually matters
Debt totals are only half of a balance sheet. Paying down $10,000 of a credit card improves your net worth by exactly as much as saving $10,000 — and at 22% interest, it's a far better guaranteed return than you'll get anywhere else.
