How is a 5.0 weighted GPA calculated?

The formula is identical to the standard 4.0 GPA formula: GPA = Σ(Credits × Grade Points) ÷ Σ(Credits). The only difference is that AP/IB courses earn +1.0 bonus points added to the base grade point — capped at 5.0. For example, an A (4.0 base) in an AP course scores 5.00; a B+ (3.3 base) scores 4.30.

Is this calculator affiliated with any school?

No. This is an independent, free tool and is not affiliated with any school or institution. The calculations follow the standard US AP/IB-weighted 5.0 Scale GPA methodology. Your official GPA is determined solely by your institution — always verify by checking your official transcript.

How is cumulative GPA calculated on the 5.0 Scale?

GPA = Σ(Credits × AP/IB Grade Points) ÷ Σ(Credits). For each AP/IB course, the grade point is base + 1.0, capped at 5.0 (e.g., A = 5.00, A− = 4.70, B+ = 4.30, B = 4.00, B− = 3.70). A 4-credit AP course carries exactly twice the weight of a 2-credit one.

Can I calculate GPA for multiple semesters?

Yes. Click "Add Semester" to add as many terms as you need. The calculator displays each semester's AP/IB GPA individually and automatically computes your cumulative GPA across all semesters. You can rename each semester (e.g., "Fall 2024", "Spring 2025") to keep records organised.

Can I save my results?

Yes. Click "Save" on the result card after entering your courses. Your result is stored locally in your browser — no data is sent to any server. You can review, compare, and delete past calculations from the History page at any time.

What 5.0 Scale GPA is considered good?

On the 5.0 AP/IB Scale, a GPA of 4.5 and above is typically considered excellent. 4.7–5.0 reflects a near-perfect AP/IB record and places a student among the top academic performers. 4.3–4.6 is Dean's List territory at most schools. The exact thresholds for honours, scholarships, and programme admissions vary by institution — always check your school's handbook.

Do credit hours affect my 5.0 Scale GPA?

Yes — significantly. A 4-credit AP course carries twice the GPA weight of a 2-credit one. If you earn an A in a 4-credit AP course (5.00 points), that contributes 20.0 quality points; a 1-credit elective earns only 5.00. Concentrating your AP/IB effort on high-credit core requirements has the greatest per-course impact on your cumulative GPA.

Does this calculator save data to a server?

No. All data you enter — course names, grades, credits — is stored only in your browser using IndexedDB. Nothing is transmitted to any server, and no account is required. Clearing your browser's local storage will erase your saved history, so export any results you want to keep.

About This 5.0 GPA Calculator

The US 5.0 AP/IB scale assigns grade points from 5.0 (A in AP/IB) down to 0.0 (F), then weights each by credit hours to compute your cumulative GPA. This calculator is pre-loaded with the AP/IB grade-to-point mapping — no manual setup needed. It opens in Weighted AP/IB mode by default and supports multiple semesters, a What-If planning mode, and local save/export. All data stays in your browser with no server involvement.

How to Use the 5.0 GPA Calculator

Follow these steps for an accurate GPA result

1Start in Weighted AP/IB Mode

The calculator opens in Weighted mode by default — the correct setting for a 5.0 Scale GPA. In Weighted mode, AP and IB courses earn +1.0 bonus points over the standard grade point (e.g., an A in an AP course scores 5.0 instead of 4.0). On the 5.0 Scale, all courses are treated as AP/IB. The toggle at the top of the calculator lets you switch to Unweighted if you need a direct comparison.

2Enter Your AP/IB Courses

Each semester starts with three course rows, all defaulting to AP/IB type. Click "Add Course" to add more. For each course, optionally type a name, set the credit hours, and pick your letter grade from the US scale. The grade point assigned is the AP/IB-weighted value — A earns 5.00, A− earns 4.70, B+ earns 4.30, and so on up to the 5.0 ceiling.

3Add All Your Semesters

Click "Add Semester" to add as many terms as you need. The calculator computes both per-semester AP/IB GPA and your running cumulative GPA across all semesters as you type. You can rename each semester (e.g., "Fall 2024") to keep your records organised.

4Review Your 5.0 Scale GPA Result

The result card shows your cumulative GPA out of 5.0, total credit hours, total courses, and a performance label. Because the scale tops out at 5.0, a result near 4.7–5.0 reflects a near-perfect AP/IB record. Use the What-If button to save your current data and safely model how a planned grade would change your GPA without losing your real entries.

5Save, Download, or Share

Click "Save" to store your GPA result locally in your browser — nothing sent to a server. Use the download button to export as a formatted PDF or PNG image. The share button copies a summary link you can send directly from your phone.

How GPA Is Calculated on the 5.0 AP/IB Scale

1The Formula

GPA = Σ (Credits × AP/IB Grade Points)

Σ Credits

Each credit hour is multiplied by the AP/IB grade-point value, summed, then divided by total credit hours.

2AP/IB Grade-Point Bonus

•AP/IB courses earn +1.0 bonus points on top of the standard grade point, capped at 5.0.
•An A in an AP course scores 5.00 (4.0 base + 1.0 bonus).
•A B+ in an AP course scores 4.30 (3.3 base + 1.0 bonus).
•The bonus recognises college-level rigour — a student who earns a B in AP outperforms one who earns a B in a standard course.

Frequently Asked Questions

Common questions about calculating GPA at 5.0 GPA Calculator

A 5.0 GPA scale is the weighted version of the standard US 4.0 scale, used when a student takes AP (Advanced Placement) or IB (International Baccalaureate) courses that earn a +1.0 grade-point bonus. On this scale, the maximum achievable GPA is 5.00 — earned by a student who takes all AP/IB courses and earns an A in each.
