How to Calculate Your Weighted GPA (Step-by-Step)

The Formula Is Simpler Than You Think

Calculating your weighted GPA follows the same basic process as unweighted GPA, with one extra step: adding bonus points for advanced courses. Here is how to do it.

Step 1: Assign Quality Points to Each Grade

Standard scale:

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 = 1.0, F = 0

Step 2: Add Weight for Advanced Courses

Most schools use this weighting (though yours may differ):

• AP courses: add 1.0 to the quality points (A = 5.0, B = 4.0, etc.)
• Honors courses: add 0.5 (A = 4.5, B = 3.5, etc.)
• Regular courses: no adjustment

Check your school's specific policy. Some schools weight honors the same as AP. Some add 0.5 for honors and 1.0 for AP. Others have different tiers entirely.

Step 3: Multiply and Average

For each course: multiply the weighted quality points by the number of credits (usually 1.0 for a full-year course or 0.5 for a semester course).

Add up all the weighted quality points. Divide by total credits. That is your weighted GPA.

Example Calculation

Say you have these junior year courses:

AP US History: A (4.0 + 1.0 = 5.0) x 1.0 credit = 5.0

AP Chemistry: B+ (3.3 + 1.0 = 4.3) x 1.0 credit = 4.3

Honors English: A- (3.7 + 0.5 = 4.2) x 1.0 credit = 4.2

Regular Pre-Calculus: A (4.0 + 0 = 4.0) x 1.0 credit = 4.0

Regular Spanish 3: B (3.0 + 0 = 3.0) x 1.0 credit = 3.0

PE: A (4.0 + 0 = 4.0) x 0.5 credit = 2.0

Total weighted points: 5.0 + 4.3 + 4.2 + 4.0 + 3.0 + 2.0 = 22.5

Total credits: 5.5

Weighted GPA: 22.5 / 5.5 = 4.09

Your unweighted GPA for the same grades would be: (4.0 + 3.3 + 3.7 + 4.0 + 3.0 + 4.0) / 6 = 3.67

The weighted GPA rewards you for taking AP and honors courses, even when you do not earn a perfect grade in them.

Cumulative vs Semester GPA

Your cumulative weighted GPA includes all semesters from freshman year through the most recent completed term. Each semester's courses feed into one running calculation. Most schools calculate this automatically, but if you want to project future changes, running the math yourself helps.

Why Your School's GPA Might Differ

Your school may include or exclude certain courses from GPA calculation (PE, health, arts). Some schools cap honors points. Some use a 100-point scale converted to 4.0. The calculation above is the most common method, but your school's policy may produce a different number.

Your official GPA is whatever your school calculates and reports. The formula above helps you understand and estimate, but the number on your transcript is what colleges see.

Using Your GPA Strategically

Once you know your weighted GPA, compare it to the middle 50 percent ranges at your target schools. Are you within range? Above? Below? This helps you build a balanced college list with appropriate safeties, targets, and reaches.
