GPA Calculator
Calculate your cumulative GPA on the 4.0 scale
The GPA calculator computes your cumulative grade point average on the standard US 4.0 scale. Add up to 20 courses with their letter grades and credit hours — the calculator weights each grade by credits and gives you your exact GPA, the letter grade equivalent, and a breakdown by grade.
The GPA formula
GPA is a weighted average — courses worth more credits count more toward your final GPA:
GPA = Σ (grade points × credit hours) ÷ Σ (credit hours)
For example: A (4.0) in a 3-credit course + B+ (3.3) in a 4-credit course = (4.0 × 3 + 3.3 × 4) ÷ 7 = (12 + 13.2) ÷ 7 = 3.60 GPA.
Letter grade to GPA points — 4.0 scale
| Letter grade | GPA points | Percentage (typical) |
|---|---|---|
| A+ / A | 4.0 | 93–100% |
| A− | 3.7 | 90–92% |
| B+ | 3.3 | 87–89% |
| B | 3.0 | 83–86% |
| B− | 2.7 | 80–82% |
| C+ | 2.3 | 77–79% |
| C | 2.0 | 73–76% |
| C− | 1.7 | 70–72% |
| D+ | 1.3 | 67–69% |
| D | 1.0 | 63–66% |
| D− | 0.7 | 60–62% |
| F | 0.0 | Below 60% |
What is a good GPA?
- 4.0 — Perfect GPA. All A's (or A+'s at schools that award 4.0 for both).
- 3.7–3.99 — Excellent. Typically qualifies for Magna Cum Laude or Dean's List honours.
- 3.5–3.69 — Very good. Strong enough for most graduate school applications and competitive employers.
- 3.0–3.49 — Good. Above the national average. Acceptable for most employers; may limit top grad school options.
- 2.5–2.99 — Average. May limit options for competitive programs or employers with GPA cutoffs (many set 3.0 minimum).
- Below 2.0 — Academic probation at many schools. Below the minimum for graduation at some institutions.
Latin honours thresholds (typical)
- Cum Laude ("with honour") — typically ≥ 3.5 GPA
- Magna Cum Laude ("with great honour") — typically ≥ 3.7 GPA
- Summa Cum Laude ("with highest honour") — typically ≥ 3.9 GPA
Exact thresholds vary by institution. Some schools use class rank percentiles rather than fixed GPA cutoffs. Always verify with your school's registrar.
Example
A student has completed 5 courses this semester:
- Calculus II — A — 4 credits
- English Composition — B+ — 3 credits
- Chemistry — B — 4 credits
- History — A− — 3 credits
- PE — A — 1 credit
Quality points: (4.0 × 4) + (3.3 × 3) + (3.0 × 4) + (3.7 × 3) + (4.0 × 1) = 16 + 9.9 + 12 + 11.1 + 4 = 53.0. Total credits: 4 + 3 + 4 + 3 + 1 = 15. GPA = 53.0 ÷ 15 = 3.53 — letter equivalent: A−. Strong semester — Magna Cum Laude territory.
Frequently Asked Questions
What is a 3.5 GPA equivalent to in letter grades?
A 3.5 GPA falls between A− (3.7) and B+ (3.3) on the 4.0 scale, roughly equivalent to an A−/B+ average. It represents excellent academic performance — above a B+ average but just below a pure A− average. Many universities recognise 3.5+ GPA for Dean's List and Magna Cum Laude candidacy.
How do I calculate my GPA with different credit hours?
Multiply each course grade (in GPA points) by its credit hours to get quality points. Sum all quality points and divide by total credit hours. Example: A (4.0) in 3 credits + B (3.0) in 4 credits = (12 + 12) ÷ 7 = 3.43 GPA. Courses with more credits have a bigger impact on your overall GPA.
What GPA is needed for medical school?
Most US medical schools require a minimum GPA of 3.0, but competitive applicants typically have 3.7+ science GPA and 3.7+ overall GPA. Top schools (Harvard, Hopkins, Stanford) typically matriculate students with 3.9+ GPAs. MCAT scores, research experience, and letters of recommendation also weigh heavily.
Does an A+ count as a 4.0 or higher for GPA?
In most US universities, both A and A+ receive 4.0 grade points — there is no 4.3 or 4.33 distinction. Some schools do award A+ = 4.3 on a modified scale, but the standard 4.0 scale treats A and A+ identically. This calculator uses the standard 4.0 scale where A+ = A = 4.0.
What is the minimum GPA to graduate college?
Most US colleges require a minimum 2.0 GPA (C average) to graduate. Some competitive programs (engineering, nursing, pre-med) may require 2.5 or 3.0. Graduate school typically requires maintaining a 3.0 GPA. Falling below the minimum puts students on academic probation, which can lead to suspension if not improved.
How much does one bad grade affect your GPA?
It depends on credit hours and your existing GPA. One F (0.0) in a 3-credit course added to a 3.5 GPA over 30 existing credits: new quality points = (3.5 × 30 + 0 × 3) ÷ 33 = 105 ÷ 33 = 3.18. A single F can drop a 3.5 GPA to 3.18 — about 0.32 points. Higher-credit courses have a proportionally larger impact.
What is a 4.0 GPA on a percentage scale?
A 4.0 GPA corresponds to A or A+ grades, typically 93–100% at most institutions. However, GPA-to-percentage conversion varies by school. A 3.0 (B average) is typically 83–86%, and a 2.0 (C average) is typically 73–76%. The calculator works from letter grades directly so no percentage conversion is needed.
What grades do I need to get a 3.0 GPA this semester?
It depends on how many credits you're taking and what your current GPA is. If you're taking 15 credits and want a semester GPA of exactly 3.0, you need an average of B (3.0) across all courses. Mix of A's and C's can average to 3.0: e.g., two A's (4.0) in 3-credit courses and three C's (2.0) in 3-credit courses = (24 + 18) ÷ 15 = 2.8. Enter your individual grades above to see the exact result.
Is a 3.2 GPA good for law school?
A 3.2 GPA is below the median for most law schools. Top-25 US law schools typically have median GPAs of 3.7–3.9. Regional and lower-ranked schools often admit students with 3.0–3.3. LSAT score can partially compensate — a high LSAT (170+) can offset a GPA in the 3.2–3.5 range at many programs.
How many A's do I need to raise my GPA from 2.5 to 3.0?
It depends on your total credits. If you have 60 credits at a 2.5 GPA (150 quality points), to reach 3.0 you need: (total credits × 3.0 − 150) more quality points. If you take 30 more credits of all A's: (90 × 3.0) ÷ 90 + 60 = but with As: (150 + 30×4.0) ÷ 90 = 270 ÷ 90 = 3.0. Generally the further behind you are and the fewer credits remain, the harder it is to raise a GPA significantly.
