About Midrange Calculator

The midrange is the average of the smallest and largest values. It is the simplest measure of centre but is extremely sensitive to outliers, since it uses only the two extreme observations.

Formula

Midrange

midrange = (minimum + maximum) / 2

Worked example

Assumptions and limits

The result is derived only from the 2 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax, fees or charges or compounding frequency into account.
Figures are rounded for display to 8 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

For 4, 7, 8, 15, 16, 23, 42?

The extremes are 4 and 42, so the midrange is 23 — well above the median of 15.

Why is it rarely used?

It ignores every value in between, so a single extreme observation shifts it completely.
