What the calculator estimates
Estimate the student loan interest deduction using the annual maximum and MAGI phaseout rules from IRS education guidance.
The page is built for quick planning around deductions and savings, with source links and a disclaimer so users understand the scope.
Inputs that matter most
The most important inputs are interest paid, MAGI, filing status. Small changes to these inputs can change the estimate, especially when a threshold or cap applies.
Use realistic annual numbers whenever possible and keep personal return details out of the browser if you are on a shared device.
How the formula works
Start with the lesser of interest paid or the annual maximum deduction, then reduce the amount ratably through the MAGI phaseout range for eligible filing statuses.
The calculator keeps year-specific rates and limits in the shared annual limits file so January updates are easier to review.
When to use related tools
After using this page, related calculators such as Taxable-income-calculator, Federal-income-tax-calculator, Standard-vs-itemized-deduction-calculator can help connect the estimate to withholding, deductions, or tax-season planning.
