Approximate percentage

90%

A 3.50 GPA averages out to about an A-.

There is no single official formula; this interpolates between the College Board's letter-grade bands.

How to use it

  1. Enter your GPA on a 4.0 scale.
  2. Read the approximate percentage and the letter grade it averages to.

The formula

Percentage ≈ interpolated between the College Board's letter-grade bands (3.0 ≈ 84.5%, 3.7 ≈ 91%, 4.0 ≈ 96%)

Good to know

  • Several universities publish their own conversion; if you're applying somewhere specific, use theirs.
  • A weighted GPA should be converted to unweighted first.

Questions

What percentage is a 3.5 GPA?

About 89–90%, between a B+ and an A-.

Is there an official GPA to percentage formula?

No. Some schools use (GPA ÷ 4) × 100, which gives 87.5% for a 3.5. That's simple but less accurate than converting through letter-grade bands.
