The service

The site provides a browser-based weighted average calculator and written reference material about weighted averages, grades, GPA, statistics, and finance. Access is free and requires no account.

Accuracy of results

The calculator applies the weighted average formula to the numbers you enter: the sum of weighted values divided by the sum of weights. Results depend on those inputs. Verify any figure before using it for an academic submission, a financial decision, or a legal filing. The site provides information, not academic or financial advice.

Availability

The site is provided “as is” and “as available”. Availability is not guaranteed, and features may change or be withdrawn without notice.

Limitation of liability

To the extent permitted by law, the site operator is not liable for any loss arising from use of the calculator or reliance on its results, including academic, financial, or business losses.

Governing terms

These terms may be updated. Continued use after an update constitutes acceptance of the revised terms, and the revision date appears at the top of this page.

Calculate Weighted Average Online

Every value-weight pair, one weighted average.

The weighted average calculator multiplies each value by its weight, adds the weighted sum, divides by the total of weights, and prints the weighted average beside the standard arithmetic mean. Course grades, GPA, portfolio returns, and probability distributions all run through the same 4 steps.
