GPA Calculator

Calculate your cumulative GPA on the standard 4.0 scale by adding each course with its letter grade and credit hours. Great for high school students tracking class rank, college students checking scholarship and honor-roll cutoffs, and applicants modeling how a final semester will move their cumulative average.

Last Updated: June 2026

Who this calculator helps

  • High school students tracking GPA against college-admissions targets.
  • College students checking scholarship, honors-list, or graduation-with-honors thresholds.
  • Transfer applicants combining grades from two schools into one cumulative number.
  • Students modeling 'what-if' grades for the current term before final exams.
  • Parents and counselors helping students set realistic study goals.

How to use this calculator

  1. Enter your numbers in each field above — the calculator updates instantly as you type, so there's nothing to submit.
  2. Use your real figures when you have them, or sensible estimates while you're planning. If a field doesn't apply, leave it at zero.
  3. Compare the results, then change one input at a time to see how each lever (price, cost, fees, volume) moves the outcome.

When to use this calculator

  • You finished a semester and want a quick cumulative or term GPA.
  • You want to see how one more A-level course would move your overall GPA.
  • You're comparing two course-load scenarios before adding or dropping a class.
  • You're applying to schools, jobs, or scholarships that ask for an unofficial GPA.

Formula

GPA = Σ(grade points × credits) ÷ Σ(credits)

Worked example

A (3 credits), B+ (4 credits), B (3 credits).

  1. Quality points: 4.0×3 + 3.3×4 + 3.0×3 = 12.0 + 13.2 + 9.0 = 34.2
  2. Credits: 3 + 4 + 3 = 10
  3. GPA = 34.2 ÷ 10 = 3.42

Answer: 3.42 GPA

More worked examples

A semester with A− (4 credits), B (3 credits), C+ (3 credits), and a 1-credit lab graded A.

  1. Quality points: 3.7×4 + 3.0×3 + 2.3×3 + 4.0×1 = 14.8 + 9.0 + 6.9 + 4.0 = 34.7
  2. Credits: 4 + 3 + 3 + 1 = 11
  3. GPA = 34.7 ÷ 11 ≈ 3.15

Answer: 3.15 GPA

Combining last term (3.6 GPA across 15 credits) with a new term: A (3), B+ (3), B (3), C (3).

  1. Existing quality points: 3.6 × 15 = 54.0
  2. New quality points: 4.0×3 + 3.3×3 + 3.0×3 + 2.0×3 = 12.0 + 9.9 + 9.0 + 6.0 = 36.9
  3. Combined credits: 15 + 12 = 27
  4. Cumulative GPA: (54.0 + 36.9) ÷ 27 ≈ 3.37

Answer: 3.37 cumulative GPA

Impact of one failing grade: A (4), A− (3), B+ (3), F (3).

  1. Quality points: 4.0×4 + 3.7×3 + 3.3×3 + 0.0×3 = 16.0 + 11.1 + 9.9 + 0.0 = 37.0
  2. Credits: 4 + 3 + 3 + 3 = 13
  3. GPA = 37.0 ÷ 13 ≈ 2.85

Answer: 2.85 GPA (one F can drop a strong term hard)

How it works

Each letter grade maps to a number of grade points (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, and so on). Multiplying grade points by the credit hours of each course gives quality points.

GPA is the credit-weighted average of those quality points, so a 4-credit class affects your GPA more than a 1-credit class with the same grade. To raise a GPA, larger classes with high grades have the biggest impact; to recover a GPA after a low grade, the same is true in reverse.

The calculator uses the standard plus/minus 4.0 scale common across most US colleges. If your school uses a 4.3, 4.5, or 5.0 weighted scale, pick the closest letter to convert your grade or apply the school's conversion table outside the tool.

Failing grades count as 0 quality points but still contribute their credit hours to the divisor, which is why a single F can pull a GPA down sharply. Pass/fail and audited courses normally carry zero credits in a GPA calculation; leave them out or list them with 0 credits in this tool.

Expert tips

  • To raise a GPA, the new grades have to come in higher than your current GPA — and the bigger the credit count, the faster the move.
  • Use the Final Grade Calculator on this site to predict each course's letter grade, then plug those into the GPA Calculator for a forward-looking GPA.
  • If your school uses a weighted scale (5.0 for AP/IB), use a converter or the school's policy before entering grades, otherwise you'll under-report your weighted GPA.
  • Cumulative GPA and term GPA serve different purposes. Use cumulative for transcripts and applications; use term for self-monitoring.
  • Many honors lists use a cutoff like 3.5 or 3.7. Add a planning row at your target GPA × remaining credits to see what you need to average going forward.

How to interpret your results

  • Dollar values are shown per sale, per order, or per item unless a result is explicitly labelled monthly, weekly, or daily.
  • Percentages (margin, ROI, conversion rate) are easier to compare across products and price points than raw dollars — use them when you benchmark.
  • A positive result means you're ahead after the costs and fees you entered. A negative result means the current numbers don't work — change a lever (raise price, cut a cost, lower ad spend) and recalculate.
  • Treat the output as a planning estimate, not a guarantee. Fees, taxes, and conversion rates shift over time — re-run the numbers whenever a key input changes.

Limitations

  • The calculator uses the standard US 4.0 scale. Weighted, international, or non-letter scales need an external conversion first.
  • It does not handle plus/minus rules unique to specific schools (some schools do not give A+ above 4.0).
  • Pass/fail, withdrawn, audited, and repeated courses follow school-specific rules that aren't modeled here.
  • It assumes you've entered every relevant course; missing a class will skew the average.

Common mistakes

  • Counting a course you withdrew from or audited — usually those carry zero credits and don't affect GPA.
  • Mixing semester and cumulative GPAs by re-entering the cumulative number as a course.
  • Entering credit hours as letters or leaving the field blank — empty rows are skipped.
  • Forgetting that an F still costs credit-hour weight in the divisor, not just in the points.

FAQ

Does this support weighted (5.0) GPAs?
Not yet — this uses the standard 4.0 scale common in most US colleges.
What if my school uses a different grade scale?
Pick the closest letter grade to your school's scale, or convert your percentage to the nearest letter.
How do I add a class with no letter grade (Pass/Fail)?
Pass/Fail courses usually don't affect GPA. Skip them, or list them with zero credits.
Do failing grades count?
Yes — an F counts as 0 grade points and still contributes its credit hours to the divisor, which lowers your GPA.
Can I model retaking a class?
Add the retake as a separate row. Many schools replace the original grade in the GPA calculation; check your registrar's policy.
What's the difference between term and cumulative GPA?
Term GPA covers a single semester. Cumulative GPA is the weighted average of every term you've completed at the institution.
How do I raise my GPA quickly?
Earn high grades in higher-credit classes. The bigger the credit count, the more leverage each grade gives you — but recovery slows as your transcript grows.
How is GPA different from class rank?
GPA is your absolute average; class rank is your position among classmates. Two students can share a GPA but rank differently if tiebreakers apply.
Is this the GPA that goes on college applications?
Colleges look at the official GPA from your transcript. Use this calculator for planning — your transcript GPA is what counts.
Does an A+ count as more than 4.0?
On the standard 4.0 scale, no — A+ is mapped to 4.0. Some schools use a 4.3 scale where A+ is higher; check yours.
Can I share this calculator with my study group?
Yes — every page on this site is free and works without an account. Just send the link.
