Weighted vs Unweighted GPA Converter
Enter your unweighted GPA, total classes, and how many were honors or AP-level to estimate your weighted GPA using a standard bonus-point method — since honors and AP courses typically add extra GPA points to reflect their difficulty.
How the Weighted vs Unweighted GPA Converter formula works
A common bonus-point estimation method:
Weighted GPA ≈ Unweighted GPA + (Bonus per weighted class × Weighted classes / Total classes)
Bonus points commonly used: +0.5 for honors classes, +1.0 for AP or IB classes, though this varies by school.
Step-by-step calculation
- Multiply the bonus point value (commonly 0.5 for honors, 1.0 for AP/IB) by the number of weighted classes taken.
- Divide by the total number of classes to spread that bonus across your full course load.
- Add the result to your unweighted GPA for an estimated weighted GPA.
Worked example
A 3.6 unweighted GPA across 24 total classes, with 6 AP classes at a +1.0 bonus: Weighted GPA ≈ 3.6 + (1.0 × 6/24) = 3.6 + 0.25 = 3.85.
Frequently asked questions
Does every school use the same weighting method?
No — weighting conventions vary significantly by school and district, including which bonus values are used and whether GPA is capped at a maximum (like 4.0 or 5.0). This calculator uses a common estimation method, but your school's official transcript is the authoritative source.
Why would I want an unweighted GPA if weighted looks higher?
Many colleges recalculate applicants' GPAs on their own unweighted or custom-weighted scale for fair comparison across different high schools' weighting systems, so both numbers are often relevant during college applications.
