How do you calculate GPA?

Multiply each course's grade points by its credit hours (quality points), add those up, then divide by total credits. For weighted GPA, add boosts (e.g., +0.5 for Honors, +1.0 for AP/IB) before multiplying by credits.

What is unweighted GPA?

Unweighted GPA uses the standard 4.0 scale without extra points for course rigor. A=4.0, B=3.0, C=2.0, D=1.0, F=0.

What is weighted GPA?

Weighted GPA includes rigor boosts (like +0.5 for Honors and +1.0 for AP/IB). Many schools cap weighted GPA at 5.0.

Do plus and minus grades affect GPA?

Yes. Common values: A−=3.7, B+=3.3, B−=2.7, C+=2.3, C−=1.7, D+=1.3, D−=0.7. Your institution may use a different table.

How do I convert percentages to letter grades?

A typical mapping is: A=93–100, A−=90–92, B+=87–89, B=83–86, B−=80–82, C+=77–79, C=73–76, C−=70–72, D+=67–69, D=63–66, D−=60–62, F<60. Schools vary-always check your handbook.

It depends on your goals. Competitive colleges often look for 3.5+ unweighted or strong weighted GPAs with rigorous coursework.

Q: What is a good GPA?

It depends on your goals. Competitive colleges often look for 3.5+ unweighted or strong weighted GPAs with rigorous coursework.

See your academic standing at a glance-this tool summarizes course results into a single grade-point average, factoring in credit weight so heavier classes count appropriately. It’s useful for checking scholarship or program thresholds, planning for honors lists, and understanding how upcoming grades might shift your standing.

The GPA Calculator lets you enter courses with credits and grades, choose the scale used by your school, and view both term and running results in one place. The goal is clarity: know where you are, what’s needed to reach a target, and how each class contributes-so you can focus study time where it matters most.

Steps to compute GPA

English: A- → 3.70 + 0.50 boost = 4.20 points × 3 cr12.60 qp
Biology: B+ → 3.30 + 1.00 boost = 4.30 points × 4 cr17.20 qp
History: B → 3.00 = 3.00 points × 3 cr9.00 qp
GPA = total quality points ÷ total credits

GPA Results interpretation

Unweighted GPA is on a 4.0 scale-course rigor doesn’t change points.
Weighted GPA adds boosts for rigorous courses then caps at your chosen maximum.
A jump from 3.2 → 3.4 usually requires several higher-credit A/B grades to offset past averages.
Use credits as your school defines them (semester hours, Carnegie units, etc.).

How this GPA calculator works

1) Convert grade → points. Example table: A=4.0, A−=3.7, B+=3.3, …, F=0. If you enter a percentage we map it to a letter using a common U.S. scale (93+=A, 90–92=A−, …).

2) Multiply by credits. Each class contributes grade points × credits (quality points).

3) Sum & divide. GPA = Σ(quality points) ÷ Σ(credits).

Show math

Let i index courses.

Unweighted:
  points_i = table(letter_i)
  qp_i     = points_i * credits_i
  GPA      = (Σ qp_i) / (Σ credits_i)

Weighted:
  boost_i   = (level_i == Honors ? h : level_i == AP/IB ? a : 0)
  points*_i = min(cap, points_i + boost_i)
  qp*_i     = points*_i * credits_i
  GPA*      = (Σ qp*_i) / (Σ credits_i)

Limitations: schools vary in letter tables, plus/minus policy, percentage cutoffs, caps, and what counts as “Honors.” Always confirm with your handbook.

FAQ

Does my school use the same boosts?

Many use +0.5 (Honors) and +1.0 (AP/IB), capped at 5.0. Some use different values-change them above.

Can I enter percentages?

Yes. Type a number (e.g., 91) and we map it to a letter using a common scale.

What if I repeat a class?

Follow your school’s policy. Some replace the old grade; others average both. Enter rows accordingly.

How many decimals should I report?

Most transcripts round to two decimals. We show two in the banner.

What’s a good GPA?

For very selective admissions, aim for ~3.7+ unweighted or a high weighted GPA with rigorous courses.

Use cases & examples

Pre-read: enter current term classes to monitor how each test shifts your GPA.
What-if: toggle a course to AP/IB to see weighted impact before enrolling.
Scholarship thresholds: check whether you meet a 3.50 requirement this semester or overall.

GPA Calculator: how to compute, improve, and interpret your GPA

GPA calculator is a phrase students search because GPA shapes placement, scholarships, internships, and graduate-school options. This page gives a fast tool and a practical guide. You can add courses, credits, and grades to see unweighted GPA on the 4.0 scale and, if you enable it, a weighted GPA with customizable boosts for Honors and AP/IB. The calculator updates instantly, shows your steps, and explains the math so you can trust the number.

GPA measures average performance by converting letter grades to points and weighting them by credit hours. Because institutions differ, our defaults mirror a common U.S. standard (A=4.0, A−=3.7, …; Honors +0.5; AP/IB +1.0; cap 5.0) yet can be changed with one click. That means you can match your handbook while still using a single, simple interface.

Why both unweighted and weighted? Unweighted tells how you performed relative to a universal 4.0 scale. Weighted compensates for rigor so a student taking AP Chemistry is not penalized compared with someone taking a lighter course. Colleges typically read both: the unweighted number shows consistency; the weighted number shows ambition.

How to use the GPA Calculator

Enter each course on a separate row. Use the letter you see on your report (A, B+, C−) or type a percentage (we convert it to a letter). Put in the course’s credit hours. If your school designates Honors or AP/IB levels, set the level and enable “Use weighted GPA.” The green banner updates as you type.

Understanding the math

GPA = total quality points ÷ total credits. A 3-credit A (4.0) generates 12 quality points. A 4-credit B+ (3.3) generates 13.2. Add every class’s quality points, divide by the sum of credits, and you have GPA. In a weighted system, add the boost before multiplying by credits, then cap at the school’s maximum (often 5.0).

Strategies to improve GPA

Focus on credit-heavy courses. An A in a 4-credit course moves your average far more than an A in a 1-credit elective.

Use office hours and practice exams. GPA improves fastest via feedback loops rather than just longer study time.

Plan your schedule. If your school weights AP/IB, one rigorous course that fits your strengths can raise your weighted GPA without overload.

Common variations and caveats

Schools sometimes omit A+ or assign A+=4.3. Some don’t use plus/minus grades. Some weight Dual Enrollment differently from AP/IB. A few compute semester and cumulative GPAs with slightly different rounding. Our calculator is flexible but neutral; always align your final number with official policy.

Key takeaways

Your GPA summarizes outcomes across courses and credits. By understanding how each grade translates into points-and previewing scenarios in this calculator-you can make informed decisions about study focus, course selection, and goals.
