Side-by-side comparison
Khan Academy vs Time4Learning
A side-by-side from Khan Academy and Time4Learning.
Khan Academy and Time4Learning are the two names new homeschoolers hear first when they look for an online, self-paced, secular program. Both run in a browser, both grade automatically, and both let a student work with minimal parent instruction. The comparison usually comes down to one loud fact: Khan is free and Time4Learning costs $39.95 a month. But the price gap hides a real difference in what each platform actually is.
Khan Academy is a nonprofit learning platform, strongest in math. Short videos, adaptive practice, and mastery tracking cover PreK math through Calculus, plus AP courses and official SAT prep. Science, history, and reading exist but run thinner. There are no ads and no upsells; the optional Khanmigo AI tutor is a separate paid add-on at about $44 per year. Khan works best as a math spine or high school supplement for a student who can self-direct through video lessons.
Time4Learning is a paid PreK-12 curriculum subscription covering language arts, math, science, and social studies, with high school electives at $5 per month each. Lessons are animated and interactive, grading and recordkeeping are automatic, and reports export cleanly for states that want documentation. Family discounts and annual plans bring the cost down, and it is ESA-eligible in qualifying states. The common criticism is rigor: the animation skews young and writing instruction is light.
So the real tradeoff is not free versus paid. It is a deep free math platform that leaves you to assemble the rest, versus a paid all-subjects package that is shallower per subject but complete.

The verdict
How to choose
Choose Khan Academy if the budget is zero, your student is a self-directed middle or high schooler, or you mainly need a math spine plus SAT and AP prep. Pair it with real books and a writing program and a motivated teen gets a legitimate free education.
Choose Time4Learning if you want every core subject handled in one login, you need clean records for state compliance or an ESA, your kids are younger and respond to animated lessons, or your family is transitioning out of public school and needs a soft landing. Just budget for a writing supplement, and expect a college-bound high schooler to outgrow it.
