High School GPA Calculator

A weighted GPA adjusts your grade point average to reflect how difficult your courses were. Instead of capping every course at 4.0, it adds bonus points for advanced classes — most commonly +0.5 for Honors and +1.0 for AP or IB. So an A in an AP course can be worth 5.0 grade points instead of 4.0. This rewards students who take a challenging schedule, which is why many high schools and college admissions offices look at weighted GPA alongside the unweighted figure. The exact bonus values vary by school, so confirm yours before relying on the number.

Start with each course's base grade points on the 4.0 scale, add the bonus for its course type (for example +0.5 Honors, +1.0 AP/IB), multiply the boosted value by the credit hours, sum across all courses, and divide by total credits. For instance, an A in a 3-credit AP class contributes (4.0 + 1.0) × 3 = 15 weighted points, while an A in a 3-credit regular class contributes 12. The calculator above does this automatically and shows both the weighted and unweighted results so you can compare them directly.

Yes. That is the whole point of weighting. Because Honors and AP/IB courses add bonus points on top of the 4.0 base, a student with a demanding schedule and high grades can finish with a weighted GPA of 4.5, 5.0, or even higher on some scales. A 5.0 weighted GPA typically means straight A grades in the most advanced courses available. An unweighted GPA, by contrast, can never exceed 4.0 because every course is capped at a 4.0 A. This is why the two numbers are reported separately.

Both, depending on the school. Many universities recalculate your GPA using their own formula to compare applicants fairly, often stripping out weighting or applying their own bonus rules. Admissions officers also read your transcript directly, so the rigor of your courses is visible regardless of which number is printed. The practical takeaway: a strong weighted GPA earned through challenging classes generally looks better than a perfect unweighted GPA from easier ones. Report whichever your school officially uses, but understand that admissions reads context, not just the figure.

Under the common system, an AP or IB course adds 1.0 grade point, so an A becomes worth 5.0 instead of 4.0. The effect on your overall GPA depends on how many such courses you take relative to your total credits, because GPA is credit-weighted. Two AP courses among ten will lift your weighted average noticeably; one AP course among twenty, far less. Use the calculator to try different mixes — set some rows to AP/IB and watch how the weighted figure separates from the unweighted one as you adjust.

No. Bonus points apply to grade points you actually earn, and a failing grade earns 0.0, so there is nothing to add a bonus to. An F in an AP course is still a 0.0 — the difficulty of the class does not rescue a failing grade. This calculator follows that rule: when a course is marked failed, no Honors or AP bonus is applied. The lesson is that taking advanced courses only helps your weighted GPA if you pass them with a grade above F.
