High School GPA Calculator

It depends on context. For high school: 3.5+ (unweighted) is considered strong; 3.7+ is excellent; 3.9+ is exceptional. For college admissions to selective schools, most admitted students have unweighted GPAs of 3.7-3.9. The average US high school GPA is around 3.0. For graduate school applications, most programs want 3.0+, with competitive programs expecting 3.5+.

Standard US conversion: 93-100% = A = 4.0, 90-92% = A- = 3.7, 87-89% = B+ = 3.3, 83-86% = B = 3.0, 80-82% = B- = 2.7, 77-79% = C+ = 2.3, 73-76% = C = 2.0, 70-72% = C- = 1.7, 67-69% = D+ = 1.3, 65-66% = D = 1.0, below 65% = F = 0.0. Some schools use 90-100% = A range (10-point scale) instead of 7-point. Always check your school's official conversion.

It depends on your school and the context. Many high schools give A+ a 4.3 weight, allowing students to exceed 4.0 unweighted. However, the Common Application and most colleges cap A+ at 4.0 for admissions calculations. When applying to college, your A+ grades are typically calculated as 4.0, not 4.3.

Unweighted GPA uses a 0-4.0 scale for every course regardless of difficulty. Weighted GPA adds bonus points for advanced courses (typically +0.5 for Honors and +1.0 for AP or IB), allowing GPAs above 4.0. Most US high schools report both. Colleges typically recalculate applicants' GPAs on an unweighted 4.0 scale to compare students fairly, but they also see your weighted GPA and course rigor.

Both. Colleges see both numbers on your transcript and also recalculate using their own preferred method. Most selective colleges recalculate to an unweighted 4.0 scale to compare students across different high schools. But course rigor (how many APs, IBs, Honors you took) is also a major admissions factor — so your weighted GPA still signals academic challenge.

A lot. An F counts as 0.0 GPA points, but the course's credits still count in your denominator. Example: a 3.5 GPA student with 30 credits who fails a 1-credit course drops to (3.5 × 30 + 0 × 1) ÷ 31 = 3.39. The hit is bigger early in high school when you have fewer credits to dilute the failure.

Only on weighted scales. On a standard unweighted 4.0 scale, the maximum is 4.0 (straight A's). On weighted scales, an A in an Honors course typically earns 4.5 and an A in an AP/IB course earns 5.0, so weighted GPAs above 4.0 are common for students taking advanced courses.

Cumulative GPA includes all your courses across all semesters or years. Sum the Quality Points (GPA points × credits) from every course you've taken, then divide by your total credits attempted. Don't average your semester GPAs directly — that doesn't account for different credit loads.

For state universities and less selective colleges: 3.0+ unweighted GPA is typically competitive. For selective private colleges and flagship state universities: 3.5+ unweighted. For elite colleges (Ivy League, MIT, Stanford, etc.): 3.8+ unweighted is typical for admitted students, with most coming in at 3.9+. GPA is one factor — SAT or ACT scores, essays, extracurriculars, and recommendations also matter heavily.

Yes, significantly. Your high school GPA is one of the most important factors in college admissions, alongside course rigor and standardized test scores (where required). Colleges look at trends — an upward GPA trajectory through high school is viewed positively even if your overall GPA is slightly lower than average. Your senior year first-semester grades also matter at most colleges.
