Phone vs. GPA
How is your phone affecting your grades?
Enter your screen time, study hours, and current GPA. See a research-backed projection of what your grades could look like if you redirected some phone time to studying.
How many hours a day do you spend on your phone recreationally?
Social media, videos, games. Not school or work use.
Does phone use actually affect your GPA?
Yes. Multiple peer-reviewed studies have found a negative correlation between recreational screen time and academic performance. A 2023 meta-analysis found that each additional hour of daily recreational phone use above 2 hours is associated with a 0.1 to 0.2 point GPA decrease. The relationship is driven by displaced study time, fragmented attention during studying, and disrupted sleep that impairs memory consolidation.
How much screen time do students typically have?
Research shows the average college student spends 4 to 5 hours per day on recreational phone use (excluding academic use). High school students average 3 to 4 hours. Students in the top quartile of screen time (6+ hours) consistently show lower GPAs than those in the bottom quartile (under 2 hours).
How redirecting phone time helps grades
The benefit is twofold. First, you gain study hours directly. One hour redirected from scrolling to studying adds 7 hours of study time per week. Second, you reduce attention fragmentation, meaning your existing study time becomes more effective. Studies show that students who keep phones out of sight during study sessions retain 15 to 20 percent more information than those who keep their phone on the desk.
How this calculator works
The calculator uses published research on the relationship between screen time and academic outcomes. It estimates a projected GPA improvement based on the hours you redirect and the compounding effect of better focus during study sessions. The numbers are conservative estimates, not guarantees. Individual results depend on study quality, subject difficulty, and baseline preparation.
