Weighted Grade Calculator
Computes a weighted average of scores using matching weights: the sum of (score x weight) divided by the total weight. Scores 85, 90, 78 with weights 20, 30, 50 give 83 percent.
What this calculator does
The Weighted Grade Calculator estimates your result instantly from the values you enter, using standard math & conversions formulas. Computes a weighted average of scores using matching weights: the sum of (score x weight) divided by the total weight. Scores 85, 90, 78 with weights 20, 30, 50 give 83 percent. Calculations run in your browser, so nothing you type is sent to a server, and the output is an estimate rather than a certified or official figure.

About Weighted Grade Calculator
The Weighted Grade Calculator combines several scores into one weighted average. It multiplies each score by its weight, adds those products, and divides by the total of the weights. The weights do not have to add up to 100.
Formula & Mathematical Calculation
Weighted Grade = f(Scores % (comma-separated), Weights % (comma-separated))
Calculated according to standard math formulas implemented in the calculator core.
Calculation Example
Enter Scores of 85,90,78 and Weights of 20,30,50, then click Calculate. The Weighted Grade box shows:
83 %
The note reads: Weighted grade = 83% (weights sum to 100).
Key Benefits
- Averages any number of scores by their individual weights
- Accepts comma-separated lists for scores and weights
- Divides by the actual total weight, so weights need not sum to 100
- Warns if the counts do not match or the weights total zero
How to Use this Calculator
-
Enter the scores
Type your scores as a comma-separated list, such as 85,90,78. -
Enter the weights
Type one weight per score in the Weights field, such as 20,30,50. -
Calculate and read
Click Calculate and read the Weighted Grade box.
Assumptions & Limitations
What the calculation assumes
- Every value you enter is treated as an exact, known amount.
- Any rate or interval you enter is assumed to hold for the whole period unless the form asks for it separately.
- Results use standard published formulas and account only for the values entered above.
- Rounding is applied for display; the underlying calculation uses your full precision.
- Results are returned in the same units you enter, unless the tool states the output unit.
What it does not cover
- Weighted Grade Calculator produces a calculated result for reference and learning, not a certified or official measurement.
- Real-world outcomes differ when tolerances, rounding rules or local standards apply.
- Definitions and standards vary by region and change over time; verify the convention that applies to your case.
- Figures are only as accurate as the inputs you supply — check them before acting on the result.
- For work where the result carries real consequences, confirm it against an authoritative source.
