Range calculator

Reviewed by the CalculatorHub team, edited by James Graham. Method from NIST/SEMATECH e-Handbook of Statistical Methods. Last verified 2026-06-23.

The Range calculator computes range from the relation range = max − min. It takes a single input (values (comma separated)) and returns the range. Because this is a pure mathematical or physical formula rather than a jurisdiction-specific rule, the result never changes over time: the same inputs always produce the same answer, so you can rely on it whether you are checking homework, sizing a design, or sanity-checking another tool. Enter your values in the fields below and the result updates instantly; you can also share a permalink that pre-fills the exact calculation, which is useful for teaching, reports, or collaboration. For example, with values (comma separated) = 10,20,30, the range works out to 20, and the worked example further down the page shows every step so you can follow the arithmetic and reproduce it by hand. The method is the standard form documented by NIST/SEMATECH e-Handbook of Statistical Methods, and the figure above each result carries the date it was last verified. This tool is general information and is not a substitute for professional engineering, medical, financial, or scientific advice; always check critical results against the primary source and your own judgement.

With Values (comma separated) = 10,20,30, the result is 20.

Formula: range = max − min. Source: NIST/SEMATECH e-Handbook of Statistical Methods, as at 2026-06-23.

The formula

range = max − min

Worked example

With Values (comma separated) = 10,20,30:

  1. range = max − min
  2. range = 30 − 10
  3. Range = 20

This worked example is one of the automated golden-value tests this calculator must pass before it can publish.

What this assumes

  • Inputs are real numbers in the units shown.
  • The result is the exact value of range = max − min; general information, not professional advice.

Frequently asked questions

What formula does this use?

range = max − min, the standard form documented by NIST/SEMATECH e-Handbook of Statistical Methods.

Does the result ever change over time?

No. This is a pure formula with no external rate, so the same inputs always give the same result.
