Simulate what average grade you need in remaining credits to achieve your target GPA. Unlike a regular GPA calculator, this tool reverse-calculates the required grades for graduation planning.
Choose your university's grading scale. 4.5 scale: A+=4.5, A0=4.0, B+=3.5. 4.3 scale: A+=4.3, A0=4.0 with minus grades. Check your university's academic regulations.
Enter your current cumulative GPA and total credits earned so far. Find this in your university's grade inquiry system or official transcript.
Enter total graduation credits required (usually 120-140) and your target GPA. Use quick-select buttons for common targets like 3.0, 3.5, or 4.0.
Click calculate to see the required average GPA and feasibility rating. The scenario table shows your projected final GPA for various grade levels.
A student with low early GPA (2.8) wanting to reach 3.0 by graduation (140 credits, 80 earned) needs an average of 3.27 in remaining 60 credits — roughly B+ or above consistently.
Set scholarship threshold (e.g. 3.5) as target and compare B+ vs A0 average scenarios in the table to understand how each affects final GPA.
Check feasibility of reaching 3.7+ required for top grad programs. If rated 'Very Difficult', adjust target or supplement application with research experience.
Transfer credits, recognized credits, or summer courses can change total graduation credits. Adjust the graduation credit field to see how it impacts required GPA.
A GPA Calculator computes your current GPA from grades already received. A GPA Simulator reverse-calculates what average grade you need in remaining credits to hit a future target. It answers 'what do I need to get from here to there?' — essential for graduation and scholarship planning.
Required GPA = (Target GPA × Total Credits - Current GPA × Earned Credits) / Remaining Credits. Example: Current 3.0 / 60 credits / Target 3.5 / 140 total: (3.5×140 - 3.0×60) / 80 = (490-180) / 80 = 3.875. You need ~3.875 average in remaining 80 credits.
'Impossible': required GPA exceeds maximum scale. 'Very Difficult': required > 4.0 (need mostly A+/A0). 'Challenging': required > 3.5 (need consistent A grades). 'Achievable': required > 3.0 (B+/A0 level). 'Easy': required ≤ 3.0 (B0 average sufficient).
The tool shows 'Target Already Achieved'. However, this doesn't mean you can ignore grades — check the scenario table to see how lower grades in remaining credits could still drop your final GPA below target.
4.5 scale: A+(4.5), A0(4.0), B+(3.5), B0(3.0), C+(2.5), C0(2.0), D+(1.5), D0(1.0), F(0.0). 4.3 scale: A+(4.3), A0(4.0), A-(3.7), B+(3.3), B0(3.0), B-(2.7), C+(2.3), C0(2.0), C-(1.7), D+(1.3), D0(1.0), D-(0.7), F(0.0).
Check your university's academic regulations, department guide, or student portal. Typical 4-year programs require 120-140 credits; 3-year programs 80-90. Transfer students and double-major students may have different requirements.
This tool calculates the overall required average for all remaining credits combined. For per-semester planning, divide remaining credits by semesters left and use that as a guide for each term's target.
While a GPA calculator tells you where you are, a GPA simulator tells you where you need to go. By reverse-calculating the required average for remaining credits, students can make informed decisions about course selection, study intensity, and graduation timeline. This tool is especially valuable for students recovering from a difficult semester, planning for graduate school admission, or trying to maintain scholarship eligibility.
Korean universities primarily use two grading scales. The 4.5 scale (most common) uses A+(4.5), A0(4.0), B+(3.5) and so on. The 4.3 scale includes minus grades (A-, B-, C-) with a maximum of 4.3. When applying to overseas programs, grade conversion through agencies like WES may be required, so it's important to understand which scale your university uses.
Use the simulator to anchor your targets to reality. Scholarship maintenance typically requires 3.5+. Domestic graduate programs often need 3.5-3.7+. Top overseas programs may require 3.7-4.0+. Run the simulation first, check feasibility, then build a semester-by-semester plan that accounts for course difficulty and workload.
