Calculate Your Course Grade

Two modes in one tool — see your current weighted standing as the semester progresses, or calculate the final exam score required to reach a target grade.

Grading scales vary by institution — this calculator uses the standard 0–100% percentage system. Confirm your course's official scale for formal applications.

Academic Grade Calculator

Fill optional student details, pick a mode, enter your assessments, and calculate. Everything runs in your browser.

Student information (optional)
Calculation mode
Weighted grade. Enter each assessment with its weight and grade to calculate your true current standing — useful mid-semester when not everything is graded yet.
Target final score. Work backward from your target grade. Enter your current grade, target, and the final exam's weight to find exactly what you need on it.

What this calculator does

Two ways to understand your standing.

Weighted grade

See your current standing even when completed weights do not yet total 100%.

Target score

Find the exact final exam score needed to reach your target.

Modes, formulas & worked examples

Each mode of this calculator, the formula it uses, and a one-click example you can load straight into the tool.

Weighted grade

Track progress through the semester

User case

A college student mid-semester wants to know their true standing in Physics 101, where homework is worth 20%, the midterm 30%, and the final 50%.

How it's calculated

Grade = Σ(Score × Weight) ÷ Σ(Weights)
(90×20 + 80×30 + 88×50) ÷ 100 → 86.00%

Who uses it

  • University students in weighted courses
  • AP and IB high school students

Applications

Mid-semester check-ins, study prioritization, scholarship eligibility.

Target final score

Know exactly what you need on the final

User case

A student with an 85% current grade wants an A (90%), and the final exam is worth 30%. What score is needed?

How it's calculated

Required = (Target − Current × (1 − Weight)) ÷ Weight
(90 − 85 × 0.70) ÷ 0.30 → 101.67% (needs extra credit)

Who uses it

  • Students in finals week planning study intensity
  • Advisors setting realistic goals with students

Applications

Final-exam prep, extra-credit requests, drop/keep decisions.

Grade bands

What your calculated grade means

The standard US academic scale this calculator uses to estimate a letter grade from your weighted result.

Percentage rangeLetterTypical meaning
90% and aboveAExcellent — top academic tier
80% – 89%BGood — above average performance
70% – 79%CSatisfactory — meets expectations
60% – 69%DBelow average — passing in most institutions
Below 60%FFail — below the passing threshold

What this grade calculator does, and what it doesn't — no fine print.

What this calculator does

  • Calculates your current weighted grade from any number of assessments
  • Scales correctly when total weights don't yet sum to 100% (mid-semester use)
  • Finds the exact final exam score needed to reach a target grade
  • Exports results as a text report or shares via WhatsApp
  • Runs entirely in your browser — no data leaves the page

What this calculator does not do

  • Does not automatically drop lowest grades — remove them manually first
  • Does not handle point-based systems — use the Mark Percentage Calculator for that
  • Does not issue an official grade — confirm with your instructor
  • Does not convert percentages to GPA points — use the GPA Calculator for that
Accuracy tips

Get the most accurate result

Common pitfalls with weighted grading — and how to avoid them.

Match weights to your syllabus

Check your course syllabus before entering weights. A common mistake is using round numbers (20/30/50) when the syllabus specifies something like 15/35/50.

Enter all graded categories

For the most accurate mid-semester picture, enter every category that has been graded — even small ones like participation (5%) can shift your letter grade.

Handle dropped scores manually

If your course drops the lowest quiz score, remove that quiz from the list before calculating, then re-weight the remaining quizzes to sum to the category's total weight.

Watch the "above 100%" flag

In Target mode, if the required score exceeds 100%, the target is mathematically impossible on the final alone — consider extra credit, a curve, or accepting a lower target grade.

Re-check as the semester evolves

Your weighted grade changes with every graded assignment. Re-run the calculator weekly to see how your standing evolves and where to focus next.

Confirm letter grades with your course

The A/B/C/D/F scale shown here is a common US standard. Your course may use a different scale (e.g., A- at 90%, B+ at 87%) — always check your syllabus.

Frequently asked questions

Quick answers about weighted grades and using this calculator.

Understanding weighted grades

A simple average adds up all scores and divides by the number of assignments. A weighted grade assigns value based on importance — if exams are worth 70% and homework 30%, scoring low on an exam hurts your grade much more than scoring low on homework. This calculator handles that math for you.
In Weighted Grade mode, if your weights sum to less than 100 (for example 50%), the calculator scales your grade based on the completed work only. This is useful mid-semester when not all assignments have been graded yet.
Not directly. This tool calculates the percentage grade (0–100) for a specific class. Once you have that percentage, you can convert it to a letter grade or GPA point using our separate GPA Calculator or CGPA Calculator.
Not automatically. If your course drops the lowest quiz score, remove that quiz from the list before calculating, or re-weight the remaining assessments to sum to 100%.

Using the target mode

If the calculator says you need a negative score (for example -10%), it means your current grade is so high that even if you score a 0% on the final exam, you will still achieve your target grade. You have mathematically secured that grade.
It means the target is mathematically impossible on the final alone — you would need extra credit, a curve, or to retake earlier assessments. The calculator will flag this clearly.
This calculator assumes a percentage-based system (0–100). For a point-based system (total points earned ÷ total points possible), use the Mark Percentage Calculator instead.
