Calculating your range is straightforward once you know the Range formula and what each input means. This guide explains the method in plain language, walks through a manual calculation, and gives worked examples you can follow — then you can do it instantly with the Range Calculator.
What is Range?
The Range calculation tells you your range from a few simple inputs. The figure you are solving for here is the range.
The Range formula
This calculation combines several inputs through a multi-step method rather than a single one-line formula. Enter the values below and the calculator resolves each step in order. The inputs it needs are:
- Numbers (comma or space separated) — a list of numbers (one per line). Example: 4, 8, 15, 16, 23, 42.
How to calculate it step by step
- Write down the numbers (comma or space separated) (for example, 4, 8, 15, 16, 23, 42).
- Apply the formula above to get your range.
- Double-check the result with the Range Calculator.
Worked examples
Example 1
| Input / Output | Value |
|---|---|
| Numbers (comma or space separated) | 4, 8, 15, 16, 23, 42 |
| Range | 38.0000 |
| Minimum | 4.0000 |
| Maximum | 42.0000 |
With numbers (comma or space separated) of 4, 8, 15, 16, 23, 42, the range works out to 38.0000.
Tips for an accurate result
- Keep your units consistent — mixing, say, months with years or grams with kilograms is the most common source of error.
- Round only at the very end. Rounding inputs early can shift the final answer noticeably.
- Re-run the numbers whenever an input changes, rather than estimating from an old result.
