About this calculator
Parents often commit to tutoring without a clear sense of what result they're buying. This calculator turns a tutoring budget into a cost-per-session and cost-per-hour figure, then compares it against a target improvement (grade points, test score points, or GPA), so you can judge whether the price matches a realistic expected gain. It also flags the total commitment cost over a semester or test-prep cycle, since weekly tutoring compounds fast — $80/week for a semester is nearly $1,500, a number families rarely calculate up front.

FAQ
What's a realistic score improvement from SAT/ACT tutoring?
Structured tutoring over 3-6 months typically yields 100-200 point SAT gains (out of 1600) or 3-5 ACT composite points for students starting from a mid-range baseline, though results vary a lot by starting point and student effort. Diminishing returns set in above a certain point total, since the highest scorers need much more work per additional point.
Is a $70-100/hour tutor worth it versus a $30/hour one?
Higher rates often reflect subject-matter expertise (a certified teacher or subject specialist vs. a college student), test-specific credentialing, or connections to a known prep company. For foundational skill-building, a competent lower-cost tutor is often just as effective; for test strategy at the margins, specialized expertise pays off more.
How do I know if tutoring is actually working?
Set a baseline score or grade before starting and re-test every 4-6 weeks. If there's no measurable movement after 8-10 sessions, the tutor-student fit or approach likely needs to change rather than continuing to spend at the same pace.
Accuracy and limitations
- Results are estimates before tax, fees, and inflation unless an input explicitly covers them.
- Rates are treated as fixed for the whole period — variable-rate products will drift from this projection.
- This is educational maths, not financial advice. Check anything contractual with the lender or your accountant.
