How to Use the Pass/Fail Calculator
This calculator helps you with two distinct pass/fail questions that students commonly face:
- Will I Pass? โ Enter each graded item (assignments, exams, projects) with its score and weight percentage. Set your class's passing threshold and see whether your current grade is a pass or fail, plus how wide your margin is.
- GPA Impact โ Compare what your cumulative GPA would be if you take a course for a letter grade versus opting for pass/fail grading. Pass/fail courses typically do not count toward your GPA, so this comparison helps you make a strategic decision.

GPA Impact Formula
New GPA (letter grade) = (Current GPA ร Current Credits + Letter GPA ร Course Credits) รท (Current + Course Credits)
New GPA (pass/fail) = Current GPA (no change)
Example: GPA 3.2, 45 credits, 3-credit course with expected B (3.0 GPA points)
With Letter: (3.2ร45 + 3.0ร3) รท 48 = (144 + 9) รท 48 = 3.1875
With P/F: 3.200 (unchanged)

When to Choose Pass/Fail
Most colleges allow students to take a limited number of courses pass/fail. Strategic reasons to choose it:
- You expect a C or lower, and a low letter grade would hurt your GPA significantly.
- You're taking an elective outside your major and want to explore it without GPA risk.
- You're in a difficult semester and need to protect your GPA in core courses.
- The course is required but outside your strengths โ passing satisfies the requirement without GPA damage.
Note: Many graduate schools, pre-med programs, and scholarships require minimum letter-grade GPAs and may not count pass/fail credits favorably. Always check requirements for your intended path.
Frequently Asked Questions
At most US universities, a Pass grade does not affect your GPA at all โ it simply satisfies credit requirements. A Fail grade also typically doesn't affect GPA, but it does not earn credit. Policies vary by institution, so check your school's academic regulations.
The standard 4.0 scale used in this calculator: A+/A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7, C+ = 2.3, C = 2.0, C- = 1.7, D+ = 1.3, D = 1.0, D- = 0.7, F = 0.0. Some schools don't award A+ grades or don't differentiate them from A.
Yes โ the passing threshold field is fully editable. Some courses require 65%, 70%, or even 75% to pass. Enter whatever threshold your course uses. Common examples: most US undergrad courses use 60-65%, nursing and medical programs often require 75-80%.
Yes โ only enter the grades you've received so far. Leave future assignments out entirely (don't add rows with empty scores). The calculator will base the pass/fail result on your current weighted average with the assignments you have entered, with the caveat that future grades will shift the result.
The GPA Impact tab is a good starting point. Enter your current GPA, the credits at stake, and your expected grade. If the GPA drop is significant and you can't recover the grade, dropping or switching to pass/fail might protect your academic standing. Factor in your school's withdraw policy and any transcript implications before deciding.
