Student Loan Debt-to-Income Calculator

Is your student loan payment a manageable share of your income? This calculator checks your payment against common benchmarks.

Debt-to-Income = (Monthly Payment / Gross Monthly Income) x 100

Example

$400 monthly payment, $5,000 gross monthly income:

Ratio = (400/5000) x 100 = 8.0% - Manageable

The Common Benchmark Range

Financial guidance commonly suggests keeping student loan payments under roughly 8-10% of gross monthly income for a manageable debt burden - this is separate from, and typically stricter than, total debt-to-income ratios lenders use for mortgage qualification.

When to Consider Income-Driven Repayment

Ratios significantly above this range are a common signal that income-driven repayment plans - which cap federal student loan payments as a percentage of discretionary income - or refinancing to a lower rate may be worth exploring to bring the payment burden down to a more sustainable level.
