Educational estimate, not a guarantee. Actual APR depends on the lender, your state, and your creditworthiness. The effective APR includes the origination fee in the cost of credit.

Debt trap risk calculator

Your debt-to-income (DTI) ratio is the percentage of your gross monthly income that goes to debt payments. Most lenders prefer DTI below 36%. Above that, a new loan can trigger a cycle of rollovers.

Include rent/mortgage, car loan, credit cards, student loans.

Before taxes, from all sources.

20.0%

You're within the 36% guideline most lenders prefer, but approaching the upper bound. A new loan could push you over.

Readiness checklist

Before you submit a request, make sure you meet the basic criteria lenders look for. This is an educational tool — it does not predict approval or guarantee an offer.

This is not an approval prediction

This checklist helps you understand what lenders typically evaluate. It does not predict whether you'll be approved, what rate you'll get, or whether you'll receive an offer. The lender decides.
