Good Debt vs Bad Debt: How to Tell the Difference
$20,000 in student loans and $20,000 in credit card debt are not the same problem — even though they show up as the same number on a balance sheet. Here's what actually separates them.
Why treating all debt the same is a mistake
A lot of financial tools and rules of thumb lump every non-mortgage debt into one bucket. In reality, the interest rate, flexibility, and purpose of a debt matter enormously to how much it actually hurts your financial health.
A rough hierarchy of risk
| Debt type | Typical rate | Why it's ranked here |
|---|---|---|
| Credit cards | ~20–29% | Highest rates, revolving, easiest to let compound out of control |
| Auto loans | ~5–9% | Fixed rate and term, but the underlying asset depreciates fast |
| Student loans | ~4–7% | Often fixed, sometimes tax-deductible interest, tied to an asset (education) that doesn't depreciate the way a car does |
| Mortgage | ~5–7% | Lowest relative risk of common debt types — fixed, tied to an appreciating asset, often tax-advantaged |
This is why a financial health check that scores $20,000 of student loans identically to $20,000 of credit card debt is missing something real — the actual risk and cost to you is very different.
How this site scores debt differently
This calculator weighs credit card balances most heavily, auto loans moderately, and student loans lightest, when calculating your debt score — because that ordering reflects real interest-rate and flexibility differences, not because any one type of debt is "shameful." Reasonable people take on student loans and auto loans as normal parts of building a life and career.
If you're carrying a mix of debt types
A common, mathematically sound approach is the debt avalanche method: pay minimums on everything, then throw extra money at whichever balance has the highest interest rate first — usually credit cards. Some people prefer the debt snowball instead (paying off the smallest balance first for psychological momentum), which can work better if motivation, not math, is the actual obstacle.

Is a mortgage "bad debt"?
Generally not considered in the same risk category — mortgages are typically fixed-rate, tied to an asset that (over long periods) tends to appreciate, and often come with tax advantages. Most financial health measures separate mortgage debt from other debt entirely for this reason.
Should I pay off student loans before investing?
This depends heavily on the interest rate on the loan versus expected investment returns, and on personal risk tolerance — there's genuine disagreement among financial professionals here, and it's not a one-size-fits-all answer.
