What is a GPA calculator?

A GPA calculator computes your Grade Point Average — a numerical summary of your academic performance — by combining the grade points earned in each course, weighted by the number of credit hours. The Texterfly GPA Calculator uses the standard 4.0 scale and supports any number of courses, custom credit hours, and any letter grade system.

What is the 4.0 GPA scale?

The 4.0 scale is the most common GPA system in the US. It maps letter grades to grade points: 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. GPA is calculated by multiplying each course's grade points by its credit hours, summing all results, and dividing by total credit hours.

How do I calculate GPA manually?

Step 1: Convert each letter grade to grade points (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0, with +/- adjustments). Step 2: Multiply each course's grade points by its credit hours (quality points). Step 3: Add all quality points together. Step 4: Divide the total quality points by total credit hours. Example: A (4.0) in a 3-credit course + B (3.0) in a 4-credit course = (12 + 12) ÷ 7 = 3.43 GPA.

What is the difference between weighted and unweighted GPA?

An unweighted GPA uses the standard 4.0 scale for all courses regardless of difficulty. A weighted GPA gives bonus grade points for harder courses — Advanced Placement (AP) and Honors classes add 0.5 to 1.0 extra grade points, resulting in a scale that can reach 5.0 or higher. Colleges generally recalculate your GPA on their own unweighted scale when reviewing applications.

What GPA do I need to get into college?

Requirements vary widely: highly selective universities (Harvard, MIT, Stanford) typically see admitted students with 3.9–4.0+ weighted GPAs. Selective universities typically look for 3.5–3.9. Mid-range universities often accept 3.0–3.5. Community colleges and open-enrollment institutions generally accept all students regardless of GPA. Always check the specific requirements of institutions you are applying to.

What GPA do I need to maintain for a scholarship?

Scholarship GPA requirements vary by award: most merit scholarships require 3.0–3.5 minimum. Prestigious scholarships (National Merit, Rhodes Scholar) typically require 3.7–4.0. Athletic scholarships (NCAA Division I) require a minimum 2.3. Federal financial aid (FAFSA) requires Satisfactory Academic Progress, usually 2.0. Always check the specific renewal terms of your scholarship.

What is a cumulative GPA?

Your cumulative GPA is the average of all grades across all semesters of your academic career, weighted by credit hours. It differs from your semester GPA, which only covers one term. Colleges and employers typically refer to your cumulative GPA. To calculate it, include all courses from all semesters in the GPA Calculator.

How do I raise my GPA?

Your GPA is weighted by credit hours, so courses worth more credits have more impact. To raise your GPA: focus on high-credit core courses first, consider retaking courses where you earned low grades if your institution allows grade replacement, take manageable course loads to maintain quality, and use the GPA Calculator to model how different grade outcomes would affect your average before enrolling.

Is the GPA Calculator free?

Yes. The GPA Calculator is 100% free with no registration, subscription, or payment required.

Is my academic data private?

Yes. All GPA calculations run entirely in your browser. Your course names, grades, and credit hours are never sent to any server or stored anywhere.

Free Weighted Grade Calculator

Most classes don't grade everything equally — homework might be worth 20% of your grade, quizzes 30%, and a final exam the remaining 50%. Averaging your raw scores together ignores that weighting entirely, which is why a dedicated weighted grade calculator gives a very different (and more accurate) number than just averaging percentages by hand. Set up your categories to match your syllabus, enter your scores, and your current grade updates instantly.

How Weighted Grades Are Calculated

Each category's average is its total points earned divided by total points possible. Your overall grade is then the weighted average of every category you've entered scores for — categories with no scores yet are automatically excluded, so your "current grade" always reflects only the work that's actually been graded so far.

Overall Grade = Σ (Category Weight × Category Average) ÷ Σ (Weight of Completed Categories)

How to Calculate What You Need on Your Final

This is one of the most-asked questions every finals season, and it comes down to solving one equation. If your final is worth a known percentage of your grade, and you know your current grade and target grade, you can solve directly for the score you need on the final:

Score Needed = (Target Grade − Current Grade × (1 − Final Weight)) ÷ Final Weight

The "What Do I Need?" calculator above does this automatically, and also shows your best-case and worst-case outcomes so you know exactly where you stand before you even sit down for the exam.

Frequently Asked Questions

How do you calculate a weighted grade?

Multiply each category's average by its weight (as a decimal), add those together, and divide by the total weight of the categories you've completed. This calculator does that automatically as you enter scores.

How do I find out what I need on my final exam?

Enter your current grade, your final exam's weight, and your target overall grade into the final exam calculator on this page — it solves for the exact score you'd need on the final.

Is this the same as a GPA calculator?

No. This calculates the grade for a single class based on its assignments and weights. A GPA calculator instead combines final grades across multiple classes into one cumulative average.

What if my category weights don't add up to 100%?

The calculator shows a warning if your weights don't total 100%, but it still works correctly in the meantime by proportionally weighting only the categories you've entered scores for.

Does it save my grades?

No — everything runs locally in your browser for the current session and nothing is sent to a server. Refreshing the page will reset your entries.
