Weighted GPA Calculator

Unweighted GPA uses the standard 4.0 scale for every class, so an A is always 4.0. Weighted GPA adds bonus points for harder classes — usually +0.5 for Honors and +1.0 for AP or IB — so an A in an AP class counts as 5.0. That is why weighted GPAs can go above 4.0.

The standard US 4.0 scale: A = 4.0, A- = 3.7, B+ = 3.3, down to F = 0.0. Honors and AP/IB bonuses are added on top, giving a maximum of 5.0 for an A in an AP or IB class.

For each class, take the grade points (A = 4.0, B = 3.0 …), add 0.5 if it is Honors or 1.0 if it is AP/IB, and multiply by the class credits. Add those up and divide by your total credits. This calculator does all of that as you type.

Many colleges recalculate GPA with their own formula, and often look at both. Weighted GPA shows the difficulty of your schedule; unweighted GPA makes schools easier to compare. It is worth knowing both, which is why this tool shows them side by side.

No. Most schools only add the bonus to passing grades, so an F counts as 0.0 even in an AP or Honors class. This calculator follows that rule.

Weighting rules vary between schools — some add +1.0 for Honors or give no bonus below a C. This calculator uses the most common system (+0.5 Honors, +1.0 AP/IB). Check your school handbook if your numbers need to match an official transcript.
