CGPA & GPA Calculator: Track Grades Across Semesters

Scholarships, graduate school, and graduation honors all come down to one number — but computing it by hand across multiple semesters is tedious and easy to get wrong. A free CGPA and GPA calculator converts letter grades and credit hours into semester GPA and cumulative CGPA instantly, with credit-weighted math built in.

GPA tracks one term; CGPA tracks your entire academic career. Knowing both lets you measure immediate performance and long-term standing — and run “what grade do I need?” scenarios before finals week.

How GPA and CGPA Are Calculated

Each letter grade maps to quality points (A = 4.0, B = 3.0, etc.). Multiply grade points by credit hours for each course, sum the quality points, and divide by total credits:

Example: 4-credit A (16 pts) + 3-credit B (9 pts) = 25 quality points ÷ 7 credits = 3.57 GPA.

CGPA uses the same formula but sums quality points and credits across all semesters. A common mistake is averaging semester GPAs directly — that only works when every term has identical credit loads.

Plan Ahead with a GPA Calculator

Manual calculation at the end of every term invites errors — especially with plus/minus grades and fractional credits. A GPA calculator lets you enter target grades for upcoming courses and see exactly what you need to hit a scholarship threshold or honors cutoff.

Step-by-Step: Calculate Your Grades

Open the ToolMars CGPA & GPA Calculator and follow these steps:

1. Set your grading scale — 4.0, 5.0, 10.0, or percentage-based.
2. Enter each course — name, letter grade, and credit hours.
3. Add previous semesters for cumulative CGPA.
4. Review results — semester GPA, overall CGPA, total credits, and quality points.

Sample GPA Calculation in TypeScript

export function calculateAcademicStanding(semesters: { courses: { gradePoints: number; credits: number }[] }[]) {
  let totalCredits = 0;
  let totalQualityPoints = 0;

  const semesterSummaries = semesters.map((sem, index) => {
    let semCredits = 0;
    let semPoints = 0;
    sem.courses.forEach(c => {
      semCredits += c.credits;
      semPoints += c.gradePoints * c.credits;
    });
    totalCredits += semCredits;
    totalQualityPoints += semPoints;
    return { semesterNumber: index + 1, gpa: semCredits > 0 ? semPoints / semCredits : 0 };
  });

  return {
    semesters: semesterSummaries,
    cgpa: totalCredits > 0 ? totalQualityPoints / totalCredits : 0,
  };
}
