Average Calculator

Calculate mean, weighted average, and other types of averages for a set of numbers.

Result

Fill in the fields above, then press Calculate.

An average calculator computes the arithmetic, geometric, harmonic, or weighted mean of a set of numbers along with related statistics.

Enter comma-separated numbers and select the type of average. For weighted average, enter alternating value,weight pairs (e.g., 90,3,80,2). The calculator shows the result along with additional statistics.

Examples

Arithmetic

Mean of 10, 20, 30 = (10+20+30)/3 = 20

Geometric

Mean of 2, 8, 32 = (2×8×32)^(1/3) = (512)^(1/3) = 8

Weighted

Grades 90(weight 3), 80(weight 2): (90×3+80×2)/(3+2) = 430/5 = 86

Frequently Asked Questions

When should I use geometric mean?
Use geometric mean for rates of change, growth rates, and ratios. It is ideal when values are multiplied together, like compound interest rates.
What is harmonic mean used for?
Harmonic mean is used for averaging rates, like speed. For example, if you drive 60 mph one way and 40 mph back, the harmonic mean gives the true average speed.
How does weighted average work?
Weighted average gives more importance to certain values. Enter alternating value,weight pairs. Higher weights mean more influence on the result.
