Quick check: what do I need on my final?
Required on the final
Enter your numbers above.
The solid marker is your grade so far; the amber marker is your target.
Uses the common US scale (A 90+, B 80–89, C 70–79, D 60–69). Need plus/minus grades, dropped scores or a multi-part final? Use the full Final Grade Calculator.
Grade calculators
Start with the one that matches the question you are actually asking. All eleven recalculate as you type and keep nothing after you close the tab.
Final Grade Calculator
What score do you need on the final to finish the class at a B, an A-, or whatever you are chasing? Tells you plainly when the target is out of reach.
ToolGrade Calculator
Add every assignment, quiz and exam with its weight and see your current course percentage, letter grade and how much weight is still unmarked.
ToolWeighted Grade Calculator
Category-based grading — homework 20%, midterms 40%, final 40%. Handles categories whose weights do not add to 100 and shows you exactly what it assumed.
ToolTest Grade Calculator
Number of questions, number wrong, out comes the percentage and letter grade — plus a full wrong-answer chart you can scan without re-entering anything.
ToolSemester GPA Calculator
This term's courses, credit hours and letter grades, weighted properly into one semester GPA. Supports plus/minus and lets you edit the point values.
ToolCumulative GPA Calculator
Combine your existing GPA and credits with this term to project the new cumulative figure — and work backwards to what you need to hit a target GPA.
ToolPercentage to Letter Grade
Convert a percentage to a letter and a 4.0 grade point, on the standard scale or a custom one you set yourself. Includes the full conversion chart.
ToolExam Study Planner
List your exams, dates and how shaky you feel on each; get a day-by-day revision table that front-loads the weak subjects and leaves a review pass before each paper.
ToolGrade Curve Calculator
See how a flat, scaled, square-root or percentile curve would change your grade — try each method side by side. Real curves are set by your instructor, not by this page.
ToolExtra Credit Calculator
Work out how many extra credit points close the gap to your target grade, or see what a specific assignment is actually worth. Two modes, same weighted-average maths.
ToolPass/Fail Decision Helper
Compare your GPA with the course graded normally against taking it pass/fail, side by side with real numbers, before your school's deadline to switch passes.
More exam-specific variants
Same maths as the calculators above, tuned to one target grade or one test length so you can jump straight to your number.

- Test Grade Calculator for a 20-question, 25-question, or 50-question test.

The one formula behind all of it
Almost every question in this module reduces to a weighted average. Your course grade is the sum of each component's score multiplied by its weight. Rearranging that for the one unknown score — the final you have not sat yet — gives the formula every "what do I need" tool on the internet uses:
Worked example: you are at 84%, you want 90%, and the final is worth 30%. Then required = (90 − 84 × 0.70) / 0.30 = (90 − 58.8) / 0.30 = 104%. That is above a perfect paper, so a 90 is gone — and an honest calculator should say so rather than quietly rounding it to 100.
This assumes the graded portion of your course makes up exactly the remaining 1 − w of the grade. If part of the course is still unmarked besides the final, use the Weighted Grade Calculator instead, which tracks each category separately.
The grading scale these tools use by default
There is no single US grading scale — plus/minus systems, cut-offs and grade point values are set by each institution, and some universities use a scale that is not out of 4.0 at all. The table below is the widely used default; every tool in this module lets you change the cut-offs if your syllabus disagrees.
| Letter | Percentage | Grade points |
|---|---|---|
| A+ | 97–100% | 4.3 |
| A | 93–96% | 4.0 |
| A− | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B− | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C− | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D− | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Many schools cap an A at 4.0 and do not award 4.3 for an A+. Check your registrar's page before treating any conversion as official.
Frequently asked questions
How do I work out what I need on my final exam?
Take the grade you want, subtract your current grade multiplied by the share of the course that is already graded, then divide by the final's weight. For a target of 90%, a current grade of 84% and a final worth 30%, that is (90 − 84 × 0.70) ÷ 0.30 = 104%. The Final Grade Calculator does this for you and also handles plus/minus targets and multi-part finals.
What if the calculator says my target is impossible?
It means that even a perfect score on the final leaves you short, and no arithmetic will change that. Our tools show the highest grade still mathematically available so you know what you are actually playing for. At that point the useful moves are practical ones: ask whether any assignment can still be resubmitted, whether extra credit exists, and what your school's deadline is for withdrawing or switching to pass/fail.
Do these calculators work with my school's grading scale?
Yes. Grading scales vary by institution — cut-offs, whether plus and minus grades exist, and what each letter is worth in grade points are all set locally. Every tool here starts on the common US scale and lets you edit the cut-offs and point values, so you can match your syllabus exactly.
What is the difference between a grade calculator and a GPA calculator?
A grade calculator works inside one course: it combines assignments and exams by weight into a single percentage for that class. A GPA calculator works across courses: it converts each course's letter grade into grade points, weights them by credit hours, and averages them. Use the Grade Calculator during a term and the Semester or Cumulative GPA Calculator once grades are posted.
Is anything I type saved or uploaded?
No. Every tool in this module runs entirely in your browser as plain HTML and JavaScript. There is no account, no server call and no analytics. Tools that remember your entries store them in your own browser's local storage, and clearing your browser data removes them.
