CGPA Calculator, Semester GPA Calculator, Weighted Grade Calculator & CGPA to Percentage Converter (All-in-One)
Instead of jumping between four separate pages to track your academic standing, our unified 4-in-1 Academic Grade Suite combines the CGPA Calculator, Semester GPA Calculator, Weighted Course and Final Grade Calculator, and CGPA to Percentage Converter on one single, fast page. Whether you are a university student on a 4.0, 5.0, or 10.0 grading system, a high school student calculating AP/IB semester grades, or a graduate applicant converting CGPA to percentage for job portals and scholarship forms, every calculation happens instantaneously in your browser.
You can switch between the four specialized calculators using the mode tabs at the top of the workspace, or click "Show All 4 Calculators Together" to display all four calculators side by side on the same screen. Every formula follows official university registrar standards, credit-hour weighting rules, and international grading scales with zero sign-up and 100% client-side privacy.
Formulas & Architecture for All 4 Calculators (CGPA, GPA, Course Grade & Percentage)
1. Cumulative GPA (CGPA) & Semester GPA Formulas: Your Semester GPA (SGPA) is computed by multiplying each course grade point by its credit hours and dividing by the total semester credits: GPA = Sum(Grade Points x Credits) / Sum(Credits). Your Cumulative GPA (CGPA) aggregates every semester across your degree program: CGPA = Sum(Semester GPA x Semester Credits) / Total Degree Credits, supporting 4.0 (US/Canada/HEC), 5.0, and 10.0 (India/Europe/Asia) scales with full plus/minus letter grade precision.
2. Weighted Course Grade & CGPA-to-Percentage Formulas: For individual classes, the Grade Calculator computes your running weighted average from homework, labs, quizzes, and midterms, and solves for the exact final exam score needed to hit your target grade. Meanwhile, the CGPA to Percentage Converter translates between cumulative grade points and percentage marks in both directions using verified CBSE/UGC (CGPA x 9.5), 10-point direct (CGPA x 10), and 4.0 scale equations.

Expert Academic Tips for CGPA, GPA, Course Grades & Percentage Conversion
Prioritize High-Credit Courses for Maximum GPA Lift
A 4-credit lab course impacts your semester GPA and cumulative CGPA 33% more than a 3-credit elective. Use the GPA tab to simulate which course gives the largest CGPA boost.
Check Your University Official Multiplier for Percentage
CBSE and many UGC universities use CGPA x 9.5, whereas some technical universities use CGPA x 10 or (CGPA - 0.5) x 10. Select the exact multiplier in the CGPA to Percentage tab.
Calculate Your Final Exam Target Before Finals Week
Use the Grade Calculator tab two weeks before finals to see which class requires an 85%+ on the final exam to cross the next letter-grade boundary.
