What is Grade Calculator?

Find out what score you need on remaining assignments or your final to hit your target grade. Plug in your current grade and the weight of upcoming work, and you'll see the minimum you need.

Three input modes cover most reporting systems: percentage (0-100), GPA on a 4.0 scale, and ECTS letter grades. The result shows the exact score required plus the equivalent letter grade, and flags any target that is mathematically impossible even with full marks remaining.

How to use

1. Step 1 — Enter your current class grade as a percentage and the weight it represents of the total grade.
2. Step 2 — Set your desired final grade (e.g., 90% for an A) and enter the weight of the remaining assignment or exam.
3. Step 3 — The result updates automatically, showing the minimum score you need on the remaining work.

When to use

• Figuring out the minimum final exam score that still lands you a B (or higher) in a course.
• Deciding mid-semester whether a course is salvageable or worth dropping before the withdrawal deadline.
• Setting realistic study targets for each remaining assignment when the syllabus has multiple weighted parts.

Result

You have an 85% average on work worth 70% of the total grade. To get a 90% final grade, you need a 101.7% on the final exam worth 30% — time to aim for extra credit.

FAQ

Why does the calculator sometimes say the result is over 100%?

It means your target grade is no longer reachable with the remaining work alone. A 102% needed score implies you'd need bonus points or extra credit. Lower your target or check whether earlier grade weights were entered correctly.

What if my current grade weight plus final weight is less than 100%?

That means there's other graded work the calculator doesn't see yet — quizzes, attendance, participation. Group all unfinished items into the 'final weight' bucket and assume an average score, or run the calculation again once those grades come in.

Should I use the percentage mode or the GPA mode?

Use whichever your syllabus uses. If your course reports running averages in percent, stick with percent. If it gives letter grades only, the ECTS or GPA modes convert internally, but percent is the most precise input.

Does the calculator account for graded curves?

No, it assumes a fixed grading scale. If your instructor curves on the final, the target score you enter should reflect the post-curve grade you want, not the raw percentage. Ask the professor for the curve formula if you're unsure.

What's a realistic 'desired grade' to enter?

Start with the grade boundary you're closest to. If you have an 82% and the cutoff for an A is 90%, set 90% as the target. The needed-score result tells you whether closing that 8-point gap is plausible given the remaining weight.
