To calculate a weighted grade, multiply each assignment or exam score by its assigned weight. Add all weighted scores together to get your final percentage.
Suppose you have these scores:
Final course grade: 23.4 + 18.4 + 42.5 = 84.3%
This calculator automatically performs these calculations and displays your percentage, letter grade, and GPA equivalent.
A weighted grade assigns different importance levels to coursework such as exams, assignments, and projects. The formula is: Σ(Grade × Weight) ÷ Σ(Weights). Each assignment's percentage score is multiplied by its weight percentage, summed together, then divided by total weights to produce your final weighted average grade.
A percentage grade shows your score out of 100, while GPA converts that score into a standardized scale such as 0–4.0 or 0–5.0. For example, 93-100% = A (4.0 GPA), 90-92% = A- (3.7 GPA), 87-89% = B+ (3.3 GPA). Our calculator automatically converts between percentages and GPA using customizable grading scales.
Yes. By entering your current grade, remaining weight, and target grade, the calculator estimates the score required on your final exam. The formula used is: (Target Grade - (Current Grade × Completed Weight)) ÷ Remaining Weight. This calculator automatically computes this, accounting for your exact current standing and how much the final exam impacts your total grade percentage.
Letter grades correspond to percentage ranges. For example: A = 93-100%, A- = 90-92%, B+ = 87-89%, B = 83-86%, etc. You can input either letter grades or percentages in our calculator, and it will automatically convert between them based on your chosen grading scale.
While designed for single courses, you can calculate overall GPA by treating each course as an 'assignment' with credit hours as weights. For comprehensive multi-semester planning, use our dedicated GPA calculator for complete academic tracking.
Weighted grading represents more than just mathematics—it's a system that shows where effort creates the greatest impact. The formula Σ(Grade_i × Weight_i) ÷ Σ(Weight_i) ensures that major assessments properly influence your academic journey. This system creates strategic awareness: students learn to allocate finite energy (not just time) to what truly moves their academic journey forward.
Letter grades began as communication tools. A B+ might mean "excellent foundation with room for growth" to a teacher but feel like failure to a perfectionist student. This disconnect happens because we've forgotten grades are conversations, not verdicts. Our calculator helps bridge this gap by showing both percentage and letter grade equivalents.
The equation Required Score = (Target Grade - Σ(Current Grades × Current Weights)) ÷ Remaining Weight isn't just math—it's anxiety's antidote. Students who calculate exactly what they need replace "What if I fail?" panic with "Here's my target" focus. This simple adjustment transforms frantic exam prep into confident, manageable study sessions.
Grade Point Averages measure performance, not circumstance; results, not resilience. A 3.5 GPA earned while overcoming significant challenges often represents more growth than a 4.0 earned with every support in place. Our calculator helps students understand both weighted and unweighted GPA calculations.
If you're behind at midterm, don't panic—systematize. Weeks 1-2: Master one key concept daily. Week 3: Form a study group focused only on past exam problems. Week 4: Take practice tests under real conditions. Week 5: Teach the material to someone else.
Your time/energy should mirror assignment weights. Track your time for one week, then compare: Are you spending 40% energy on 10% worth of work? Realign. Create a pie chart showing weight percentages beside your time allocation.
Use our calculator to run scenarios: "What if I improve my lab reports by 10%?" or "What grade do I need on the final to get a B+?" This helps you set realistic goals and focus your efforts where they'll have the most impact.
