Credit hours weight your GPA — a 4-credit A counts more than a 1-credit A
3.0+ is good, 3.5+ is honors, 3.8+ is competitive for grad school
Below 2.0 = academic probation at most US colleges
W and I grades do not affect GPA
Retaking a course: policies vary (grade replacement vs averaging)
ℹ️ Over 200,000 US students use this GPA calculator 2026. Calculate your semester and cumulative GPA on the 4.0 scale with credits, plus/minus grades, and weighted AP/Honors options.
📊 4.0 Grade Scale: A+ (4.0), A (4.0), A- (3.7), B+ (3.3), B (3.0), B- (2.7), C+ (2.3), C (2.0), C- (1.7), D+ (1.3), D (1.0), D- (0.7), F (0.0)
💡 Planning Tip: If you're near a GPA threshold (e.g., 3.5 for honors), retaking a low-grade course can lift your GPA faster than adding new A's.

What is a GPA Calculator and How Does It Work?
A GPA calculator is a student tool that computes a Grade Point Average by weighting each course's grade points by its credit hours. Our GPA calculator 2026 uses the standard 4.0 scale with plus/minus grades and optional weighting for AP/Honors courses. It calculates both your semester GPA and your cumulative GPA when you provide prior GPA and credit totals.
How does the college GPA calculator work? Add each course with its credit hours and letter grade. The calculator converts each grade to grade points, multiplies by credits, sums the total grade points, and divides by total credits. Add your prior GPA and credits to get your projected cumulative GPA. The cumulative GPA calculator instantly tells you where you stand and what you need to reach your target.
Most US colleges use a 4.0 scale with plus/minus grades. The exact scale varies — some schools count A+ as 4.3, others cap at 4.0. Our calculator uses the most common standard:
A+ / A = 4.0 | A- = 3.7
B+ = 3.3 | B = 3.0 | B- = 2.7
C+ = 2.3 | C = 2.0 | C- = 1.7
D+ = 1.3 | D = 1.0 | D- = 0.7
F = 0.0
Weighted vs Unweighted GPA
Unweighted GPA treats every course equally on the 4.0 scale. Weighted GPA adds extra points for AP, IB, or honors courses — often on a 5.0 scale. Weighted GPA rewards students who take harder classes. Most colleges recalculate your GPA on their own unweighted scale during admissions, but they still look at rigor.
How to Raise Your GPA
1. Focus on high-credit courses: A 4-credit A lifts your GPA more than a 1-credit A. Prioritize courses with the most credits.
2. Retake low-grade courses (if allowed): Many schools offer grade replacement for a C- or below. Replacing an F (0.0) with an A (4.0) dramatically lifts cumulative GPA.
3. Take easier electives strategically: A lighter semester with A's can lift your GPA more than a heavy semester with B's.
4. Use grade forgiveness: Check your school's policy — some allow one free retake without penalty.
❓ Frequently Asked Questions
How is GPA calculated?
GPA = (Sum of Grade Points × Credits) ÷ Total Credits. Grade points on the 4.0 scale: A = 4.0, B = 3.0, C = 2.0, D = 1.0, F = 0.0. Plus/minus grades add ±0.3 (e.g., A- = 3.7, B+ = 3.3).
What is a good GPA in college?
A 3.0+ is generally considered good; 3.5+ is honors-level; 3.8+ is competitive for top graduate programs and employers. Below 2.0 is academic probation at most US colleges.
How do I calculate my cumulative GPA?
Cumulative GPA = (Total grade points across all semesters) ÷ (Total credits attempted). If you have a 3.5 GPA with 60 credits and add a 3.8 semester with 15 credits, your new cumulative GPA = (3.5×60 + 3.8×15) ÷ 75 = 3.56.
What is the difference between weighted and unweighted GPA?
Unweighted GPA uses the standard 4.0 scale for all courses. Weighted GPA adds extra points for AP/IB/honors courses (up to 5.0), rewarding rigor. Most colleges recalculate on their own unweighted scale.
Does a W or I grade affect GPA?
No. W (Withdrawal) and I (Incomplete) do not affect GPA. They appear on your transcript but carry zero credit points. A W does not lower your GPA; a passing grade would have raised it.
How many credits are typical per semester?
Most US colleges consider 12 credits full-time and 15 credits standard for on-track graduation in 4 years. 18+ credits is heavy but common for double majors or pre-professional tracks.
💡 Expert Tips for GPA Management
Tip #1: Track your GPA every semester, not just at the end of the year. Early awareness prevents unwelcome surprises.
Tip #2: If you're near a threshold (3.0, 3.5, 3.8), retake the lowest-grade course you can. Replacing one F with an A can lift your cumulative GPA by 0.1-0.2.
Tip #3: Use credit hours strategically. A 4-credit course has double the GPA impact of a 2-credit course — take the harder ones when you have more study time.
Tip #4: Check your school's policy on grade replacement, pass/fail, and W grades before making decisions.
