🔢 Average Calculator

What is an Average Calculator?

An average calculator quickly computes the arithmetic mean of a set of numbers. Simply enter your values and our online mean calculator adds them all up and divides by the count to give you the average. It also shows the sum, count, minimum, maximum, and range — giving you a complete picture of your dataset in seconds.

Types of Averages

• Arithmetic Mean: Sum divided by count — the most common type of average
• Weighted Average: Each value is multiplied by its weight before averaging — used for GPA, stock portfolio returns
• Geometric Mean: nth root of the product of n values — used for growth rates and investment returns
• Harmonic Mean: Reciprocal of the arithmetic mean of reciprocals — used for rates and speeds
• Median: Middle value of a sorted dataset — not technically an "average" but often more representative

Weighted Average Calculator

A weighted average gives more importance to some values than others. Formula: Weighted Average = Σ(value × weight) / Σ(weights). Used in GPA calculation (credit hours are the weights), exam score calculation (different components have different weights), and investment portfolio average returns (amount invested is the weight).

Moving Average – What It Is and How It Works

A moving average (rolling average) is calculated by averaging a fixed number of data points and moving the window forward one point at a time. For example, a 7-day moving average of daily sales smooths out day-to-day fluctuations to show the underlying trend. Moving averages are widely used in stock market technical analysis (50-day MA, 200-day MA), weather forecasting, and economic data analysis.

Practical Uses of Average Calculations

Averages are used in every field. In education: calculating class average scores, student GPA. In business: average revenue per user, average order value, average customer lifetime value. In health: average blood pressure, average blood sugar readings. In sports: batting average, goals per game, average lap time. Our mean calculator handles all these scenarios with ease.
