How Much Student Debt Is Too Much? Measuring Affordability

There is no single dollar amount of student debt that is “too much”, because what matters is how the payment compares with what you are likely to earn. A $30,000 balance can be comfortable for a nurse and crushing for someone who does not finish a degree. What you can do is turn a loan into a monthly payment, compare that payment with expected pay, and look at how borrowers at a school have actually fared. This guide shows how to do all three using the kinds of measures the College Scorecard and the Department of Education use.

Key takeaways

• Judge debt by the payment relative to income, not by the total balance alone.
• The Scorecard publishes median debt and a typical monthly payment for each school, based on federal loans and assuming a standard 10-year repayment.
• A common federal yardstick, used in rules for career-training programs, compares annual loan payments with earnings: no more than 8% of annual earnings, or 20% of discretionary earnings. It is a regulatory test, not a rule for what you personally can afford.
• Not finishing is the biggest hidden risk. Debt without a credential usually means lower earnings.
• Parent PLUS and private loans are not in the Scorecard debt numbers, so total family borrowing can be higher than the figure you see.

Step 1: Turn the balance into a payment

A balance is abstract; a monthly payment is something you can budget against. The Scorecard does this for you. Its glossary explains that the typical monthly loan payment is based on the typical total debt after graduation, using federal loan debt originated at the school awarding the credential, and assumes a standard 10-year repayment at 4.99% interest for undergraduate loans.

You can run the same calculation with your own numbers. These figures are illustrative. A 10-year payment per $1,000 borrowed is about $10.60 at 4.99% and about $11.40 at 6.52%, the fixed rate for new undergraduate federal loans first disbursed from July 1, 2026 to June 30, 2027 (see federal student loans explained).

Total borrowed	Monthly payment at 4.99%	Monthly payment at 6.52%
$10,000	about $106	about $114
$20,000	about $212	about $227
$27,000	about $286	about $307
$40,000	about $424	about $455

The Scorecard assumption is a standard plan. Real borrowers may choose longer or income-based repayment plans, which lower the monthly payment but can raise the total interest. Our student loan calculator lets you test other cases.

Step 2: Compare the payment to earnings

The Scorecard reports the median earnings of graduates who are working, measured in the fourth full year after they finish. For how to interpret these numbers, see how to read Scorecard earnings data.

Two measures help:

Annual payment as a share of earnings. Multiply the monthly payment by 12 and divide by annual earnings.

Discretionary income. A second measure subtracts a basic-living amount from earnings before comparing. In the Department’s gainful-employment rules, discretionary earnings are median annual earnings less 1.5 times the federal poverty guideline.

In those rules, a career-training program passes the debt-to-earnings test when the median annual loan payment is at or below 8% of annual earnings or 20% of discretionary earnings. A program fails only if it exceeds both. This is a threshold regulators use to judge programs, so use it as a reference point, not a personal limit. Some people can safely carry more than 8% of income, and others, with high rent or dependents, cannot carry that much.

An illustrative example

Suppose a school’s graduates have median federal debt of $27,000 and median earnings of $45,000 four years after finishing. The payment on $27,000 at 4.99% over 10 years is about $286 a month, or about $3,430 a year. Divide by $45,000 and you get a share of earnings of about 7.6%.

At 6.52%, the payment is about $307 a month, about $3,680 a year, or about 8.2% of the same earnings. At earnings of $35,000, it would be about 10.5%.

Same debt, three different answers. That is the point: the debt only means something next to the pay. The comparison is also rough, since earnings vary widely within a school and by major. Use program-level data where it is available, and see the rankings for schools with low debt relative to earnings.

Step 3: Check the school, not just the average

When you look up a school’s page, read the debt number together with three other items:

1. Graduation rate. The Scorecard’s debt figure covers borrowers who completed their credential. Students who borrowed and did not finish are not in that median, and they often face the hardest repayment, since they have the debt without the degree. See graduation and retention rates.
2. Earnings and the major. A school-wide median mixes many fields. If you plan to major in a field with typically lower pay, use that field’s earnings.
3. Net price. The best way to avoid debt is to start with a lower net price; see net price vs. sticker price.

Also note what is excluded. The Scorecard’s median debt does not include Parent PLUS loans or non-federal loans. A school that appears to have low student debt could still have families borrowing heavily through parent loans.

Step 4: Add your own budget

Population measures are a start. Your situation is the final test:

• Take-home pay. Federal tests are based on pre-tax earnings. A payment that is 8% of gross can feel larger once taxes, rent, transportation and health insurance are subtracted.
• Local cost of living. A $45,000 salary stretches differently in different cities.
• Other debts. Credit cards, car loans and other debts compete for the same dollars.
• Safety net. Think about what happens if you lose a job or switch fields.

The Consumer Financial Protection Bureau’s college-planning pages point students to tools that estimate how much they will owe and whether they will be able to repay, which is the same thinking in a worksheet form. Use whichever tool you trust, but check the assumptions it uses.

Ways to borrow less

• Lower the net price first. Compare schools using net price, not sticker price. Consider community college or transfer pathways.
• Take Subsidized loans before Unsubsidized, and Unsubsidized before any private or parent loan.
• Borrow for the year, not the program. You can accept less than the offer each year.
• Pay interest while in school on Unsubsidized loans if you can.
• Plan to finish. Time to degree is one of the biggest drivers of total cost.

Common mistakes

• Using one rule for everyone. “Borrow no more than your first-year salary” is a popular shortcut, but it ignores interest rates, repayment length and cost of living. Treat it as a rough ceiling, not a safe amount.
• Looking at debt without earnings.
• Forgetting that the Scorecard figure is for graduates.
• Ignoring parent and private borrowing, which do not appear in the school’s debt number.
• Assuming income-based plans make debt free. Lower payments can mean more interest over time, and plan rules change.

What to do next

1. List the schools you are considering and write down each one’s net price, median debt and graduate earnings from its college page.
2. Compute the annual payment as a share of earnings for each one.
3. Estimate your own payment with the student loan calculator.
4. Before you accept loans, compare offers using how to compare financial aid offers.
5. Read our methodology to see exactly how we source debt and earnings figures.
