Our Methodology

Student Loan Fundamentals is built on accuracy, transparency, and clarity. This page explains exactly how we create our tools, guides, and educational content — and how we ensure everything stays up to date with federal rules.

1. Data Sources

All tools and guides on Student Loan Fundamentals are based on publicly available, verifiable data from authoritative federal sources. We do not collect or use personal data.

  • Federal Student Aid (StudentAid.gov)
  • Department of Education regulatory updates (including 2026 changes)
  • CFPB research and repayment guidance
  • Federal Reserve economic data
  • Servicer documentation and published calculation standards
  • Congressional and Federal Register publications

We cross-reference all data before publishing or updating any tool or guide.

2. How Our Tools Work

Every calculator on this site uses standardized formulas published by the Department of Education and Federal Student Aid. We translate these formulas into clear, easy-to-use tools that help borrowers understand their options.

Our tools incorporate:

  • 2026 income-driven repayment formulas
  • Federal poverty guidelines for discretionary income calculations
  • State-specific tax and cost-of-living adjustments (where applicable)
  • Interest accrual and capitalization rules
  • Forgiveness timelines for PSLF and IDR
  • Standard, Graduated, and Extended repayment formulas

All results are estimates. Actual payments may vary based on servicer calculations, income documentation, and borrower-specific circumstances.

3. Editorial Standards

Our content is independently written, researched, and reviewed. No lender, servicer, or financial institution influences our rankings, recommendations, or educational materials.

We follow these principles:

  • Accuracy: Every guide is based on official federal documentation.
  • Neutrality: We do not promote specific lenders or servicers.
  • Clarity: Complex rules are explained in plain language.
  • No sales language: We avoid lead-gen tactics and pressure wording.
  • Transparency: We disclose how we make money and how tools work.

4. Update Schedule

Student loan rules change frequently. We maintain a structured update schedule to ensure our tools and guides remain accurate.

  • Quarterly: Review of federal repayment rules and poverty guidelines.
  • Annually: Update of income thresholds and tax-related assumptions.
  • As Needed: Updates triggered by new Department of Education regulations.
  • Immediately: Corrections to any inaccuracies reported by users.

When major changes occur — such as the July 1, 2026 overhaul — we update all tools and guides site-wide.

5. How We Make Money

Student Loan Fundamentals is free to use. We do not sell user data, and we do not require accounts or email sign-ups.

We earn revenue through:

  • Ad placements: Display ads served through Google AdSense.
  • Occasional affiliate links: Only when relevant and clearly disclosed.

Our editorial content and tools are never influenced by advertisers or partners.

6. Our Mission
