GPA Calculator

What Is a GPA Calculator?

This free GPA calculator computes your semester GPA and cumulative GPA on the standard 4.0 scale used by universities and colleges across the United States, Canada, and many other countries. Enter your course grades and credit hours — this GPA calculator instantly shows your weighted GPA, total quality points, and total credit hours. Whether you are tracking your academic progress, planning which courses to prioritise, or checking your eligibility for scholarships, honours, or graduate school admission — this GPA calculator gives you the exact figures you need.

How Is GPA Calculated?

GPA (Grade Point Average) is a weighted average of your grades, where each grade is weighted by its credit hours. The formula is: GPA = Total Quality Points ÷ Total Credit Hours. Quality points for each course = Grade points × Credit hours. For example:

• Biology (4 credits, A = 4.0): 4 × 4.0 = 16 quality points
• Maths (3 credits, B+ = 3.3): 3 × 3.3 = 9.9 quality points
• History (3 credits, A- = 3.7): 3 × 3.7 = 11.1 quality points
• Total: 37 quality points ÷ 10 credit hours = GPA 3.70

How to Use This GPA Calculator

• Enter courses: For each course, select your grade from the dropdown and enter the number of credit hours. Add as many courses as needed using the Add Course button.
• Cumulative GPA: If you want to calculate your overall GPA including previous semesters, enter your existing cumulative GPA and total credit hours completed — this GPA calculator combines them with your new semester results.
• Click Calculate: Get your semester GPA, cumulative GPA (if prior credits entered), total quality points, and total credit hours.

What Your Result Means

GPA scale reference: 4.0 = A, 3.7 = A-, 3.3 = B+, 3.0 = B, 2.7 = B-, 2.3 = C+, 2.0 = C, 1.7 = C-, 1.3 = D+, 1.0 = D, 0.0 = F. Most universities require a minimum 2.0 GPA (C average) to remain in good standing. A 3.0+ GPA is generally considered competitive. Dean’s List typically requires 3.5 to 3.7+. Graduate school admission commonly requires a 3.0 to 3.5 minimum. Summa Cum Laude (highest honours) typically requires a 3.9+.

Is This GPA Calculator Accurate?

Yes — this GPA calculator uses the standard 4.0 scale with plus/minus grade distinctions as defined by most US and Canadian universities. The weighted average formula is exact. Note that some institutions use different grade point scales (e.g. A = 4.0 vs A = 4.3 for plus grades, or no plus/minus distinctions) — always verify your institution’s specific grading scale. This GPA calculator uses the most common standard scale.

How to Choose Your Inputs

• Grade: Select the letter grade you received or expect to receive. Use the grade your institution assigns — some institutions use A+ = 4.0 (same as A) while others use A+ = 4.3. This GPA calculator uses A+ = 4.0 (standard scale).
• Credit hours: Enter the credit hours (units) assigned to each course. Most courses are 3 credits; labs may be 1 credit; some major courses are 4 credits. Check your course registration or transcript for exact credit values.
• Prior GPA: For cumulative GPA, enter your existing GPA and total credits completed. If this is your first semester, leave these blank.

Is This GPA Calculator Suitable for High School Students?

Yes — high school students use GPA calculators to track their GPA for college applications. Most US colleges use a 4.0 unweighted GPA or a weighted GPA (where AP and IB courses are worth more) for admissions. This GPA calculator computes the standard unweighted 4.0 GPA. For weighted GPA, add 1.0 point to AP/IB course grades and recalculate.

Is This GPA Calculator Suitable for University Students?

Yes — university students use this GPA calculator to plan their academic strategy, check scholarship eligibility, track progress towards honours graduation, and prepare for graduate school applications. The cumulative GPA feature lets you combine current semester results with your prior academic record for a true overall GPA.

Can I Use This GPA Calculator to Plan Grade Targets?

Yes — use this GPA calculator in planning mode by entering target grades rather than actual grades. Try different grade combinations to see what GPA you can achieve if you earn certain grades. For example, you can calculate what grade you need in your remaining courses to achieve a specific target GPA by the end of the semester — adjust the grade inputs until you reach your target.

Common Mistakes When Calculating GPA

• Using simple average instead of weighted average: GPA is NOT a simple average of grade points. It must be weighted by credit hours. A 4.0 in a 1-credit course and a 2.0 in a 4-credit course gives a GPA of (4+8)/5 = 2.4, not (4+2)/2 = 3.0.
• Using the wrong grade scale: Some institutions assign A+ = 4.3 or have different cutoffs. Always check your institution’s specific grade-to-point conversion table.
• Not including all credit hours: Repeated courses, transfer credits, and failed courses all affect cumulative GPA differently depending on institutional policy. Check your registrar’s GPA calculation rules.
• Confusing semester GPA with cumulative GPA: Semester GPA is just your current semester’s performance. Cumulative GPA includes all semesters and is what appears on your transcript and is used for most official purposes.
• Not accounting for grade replacement policies: Some institutions replace the failing grade with the new grade for GPA purposes (grade forgiveness). Check your institution’s repeat course policy.

Limitations of This GPA Calculator

This GPA calculator uses the standard US 4.0 scale with plus/minus grades. It does not support scales where A+ = 4.3, percentage-based GPA calculations, weighted GPA (for AP/IB courses), international grading scales (UK Honours, Australian grading), or institutional variations in grade-point conversion. For official GPA purposes, always refer to your institution’s registrar or student portal — this GPA calculator is a planning and estimation tool.
