Grade Average Calculator

Formula Used

How to Use This Calculator

1. Choose a weighting method and grading scale at the top.
2. Add each course row with grade and credits or weight.
3. Use numeric grades (0–100) or letter grades (A to F).
4. Press Calculate to see results above the form.
5. Download CSV or PDF to save and share your report.

Why Weighted Averages Matter

A straight mean treats every course equally, but credit hours rarely match. A four‑credit science class usually represents more time than a one‑credit lab. Weighted averaging multiplies each grade percent by its credits, adds those weighted points, then divides by total credits. This approach mirrors how many schools summarize term performance and reduces the chance that a small elective overpowers a major requirement.

Collecting Clean Grade Inputs

Enter grades as numeric percentages from 0 to 100, or switch a row to letters such as A, B+, or C‑. Use the same scale your institution uses, then choose whether plus/minus is enabled. If you are missing a final score, leave the row blank until you have complete data. Clean inputs prevent rounding surprises and make the course breakdown table easier to audit.

How the Calculator Computes

For each course, the tool converts the grade into a percent, assigns a weight, and calculates weighted points. The core formula is Σ(grade% × credits) ÷ Σ(credits). An unweighted average is also shown as Σ(grade%) ÷ number of courses. Alongside the percent, an estimated GPA is produced by mapping percent bands to a common 4.0 scale so you can track progress consistently. If you select equal weighting, each course uses weight one, which is useful for quick checks when credit values are unknown. Choose rounding to match reports.

Interpreting Results for Decisions

Focus first on the weighted percent because it best reflects credit impact. Use the letter output as a quick signal, not a formal transcript replacement, since cutoffs vary. If one course drags the result, check its credits and percent to see the true driver. Then set a realistic target, such as raising a 86.3% average to 88% by improving the next assessment in the highest‑credit course.

Using Exports to Stay Organized

Download CSV to archive your inputs, share with an advisor, or combine multiple terms in a spreadsheet. Use the PDF report when you need a clean printout for a meeting. A practical routine is to recalculate after major exams, export the updated report, and note what remaining scores are required to reach your goal before the term ends.

FAQs

1) Should I use credits or equal weighting?

Use credits when courses have different credit hours or importance. Choose equal weighting for quick comparisons when every course is similar or when you do not know the credit values yet.

2) Can I include courses without final grades?

Leave incomplete rows blank until you have a reliable score. Including guesses can distort the weighted percent and the estimated GPA, especially for high‑credit courses.

3) How are letter grades converted to percentages?

Letter entries are mapped to common percent estimates, such as A=93, B=83, and C=73, with optional plus/minus steps. Your school may use different cutoffs, so treat letters as indicators.

4) Why might the estimated GPA differ from my transcript?

Schools calculate GPA using their own rules, quality points, repeated courses, and rounding policies. This calculator uses typical percent bands to provide a consistent estimate for tracking trends over time.

5) What rounding option is best?

Match the rounding used in your gradebook or report card. Fewer decimals are easier to read, while more decimals help you see small changes after each assessment.

6) Are CSV and PDF downloads safe to use?

The report is generated on your device. Downloads contain only the course data you entered, so review the file before sharing it with others.
