IXL vs. Khan Academy: Which Free (or Affordable) Homeschool Supplement is Worth It?

Not every family needs a boxed curriculum for every subject. Many experienced homeschoolers use supplemental programs to reinforce skills, address gaps, or provide independent practice. IXL and Khan Academy are two of the most popular supplemental platforms — but they serve different purposes and have very different price points. Here is how to decide which is right for your family

Overview

Khan Academy is a completely free, nonprofit platform offering video lessons and practice exercises in math, science, English, history, and test prep. It is used by millions of students worldwide and is an extraordinary resource for any homeschooling family. IXL is a subscription-based platform offering comprehensive skills practice in math, language arts, science, social studies, and Spanish. It tracks student performance in granular detail and adapts practice difficulty based on student responses.

Content Depth and Coverage

Khan Academy offers full courses across many subjects, including Algebra, Geometry, Chemistry, Biology, US History, and SAT prep. The video lessons are genuinely excellent and can serve as primary instruction for many subjects. It covers skills from kindergarten through early college. IXL is practice-focused rather than instruction-focused. It does not offer video lessons — instead, it provides thousands of structured practice questions organized by skill. It is best used alongside a primary curriculum, not as a replacement for instruction.

Reporting and Analytics

Khan Academy offers a parent dashboard showing time spent, skills completed, and mastery levels. It is useful but fairly straightforward. IXL's reporting is exceptionally detailed — arguably the most sophisticated of any homeschool platform. Parents can see exactly which skills have been practiced, how long a student spent on each, where they made errors, and how their performance compares to national standards. For parents who want data on their child's progress, IXL is unmatched.

Pricing

Khan Academy is 100% free with no premium tier. IXL costs approximately $9.95/month for one subject or $19.95/month for all subjects for one student, with family plans available.

Verdict

Start with Khan Academy — it is free, comprehensive, and genuinely excellent. Add IXL if you want rigorous skills practice with detailed reporting, particularly in math or language arts. The two platforms complement each other well: Khan Academy for instruction and concept introduction, IXL for practice and skill reinforcement. Together, they can replace significant portions of a paid curriculum at a fraction of the cost.
