Is my student loan payment affordable?

Check your loan payment against your take-home pay and your debt-to-income ratio — the two numbers lenders actually look at.

Your required student loan payment each month.

What actually lands in your bank account each month, after tax.

Car payment, credit card minimums, and any other monthly debt payments.

Your salary before tax, per year. Used for the debt-to-income ratio.

Estimate only — not financial advice. The 10% guideline (student loan payment at or under 10% of gross monthly income) and the 36% debt-to-income guideline are widely used rules of thumb, not lender requirements. Your servicer's required payment does not change because a ratio looks high — but a high ratio is a warning that the budget has no slack.

What the numbers mean

Two ratios matter. The first is your student loan payment against your pay: at or under 10% of gross monthly income is comfortable, 10–15% is workable, and above 15% the budget usually strains. The second is your total debt-to-income ratio — all monthly debts divided by gross monthly income. Under 36% is comfortable, 37–43% is a caution zone, above 43% is high.

The payment itself comes from your plan. On the standard 10-year plan it is fixed; on RAP or IBR it follows your income and can be as low as $10 a month. If the ratio looks bad, check the RAP vs IBR calculator before borrowing more — the required payment may be far lower than you think.

And remember the payment is only one line in the month. Run the total monthly burden calculator to see the loan next to the car payment, the card minimums, rent, and food — that is the number that decides whether the month works.

Frequently asked questions

How much student loan debt is too much?

A common rule of thumb: keep your total student loan debt at or below your first year's salary after graduation, and keep the monthly payment at or under 10% of your gross monthly income. Above 15% of gross income, most budgets start to strain.

What is a debt-to-income ratio?

Lenders usually add up all your monthly debt payments and divide by your gross monthly income. Under 36% is comfortable for most lenders; 37–43% is a caution zone; above 43% is high, and many lenders will not approve new credit there.

Why do you ask for take-home pay and gross income?

Take-home pay is what actually lands in your account after tax and payroll deductions. The payment has to come out of that, not out of your salary on paper — which is why this calculator asks for both.

My payment is too high. What can I do?

The main levers are income-driven repayment (RAP or IBR can cut the required payment, sometimes to $10 a month), a longer term, or paying down higher-rate debt first so the minimums shrink. Refinancing can cut the payment too, but it costs you the federal protections.

What if my payment is more than 15% of my income?

It is a warning, not a verdict. If the math says the payment eats more than 15% of your gross income, look at income-driven repayment before you borrow more — and run the total monthly burden calculator to see the whole month, not just the loan.
