RAND Formula Syntax
Example Use Case
Generating a random decimal between 0 and 1 for simulations
Understanding the RAND Formula
The RAND function in Excel generates a random decimal number between 0 and 1 (exclusive), refreshing with each recalculation. It’s a no-argument tool for simulations, testing, or random sampling—think Monte Carlo methods or mock data creation.
RAND() might return 0.74213 one time, then 0.31942 the next. It’s uniform, meaning all values in the range are equally likely, making it a simple yet powerful way to introduce randomness into your sheets.
Why Use RAND?
RAND fuels randomness—perfect for modeling uncertainty, shuffling lists, or stress-testing formulas. Its simplicity and range make it a building block for more complex random operations in Excel.
Example with Sample Data
| Description | Formula | Result (Sample) |
|---|---|---|
| Raw random | =RAND() | 0.74213 |
| Scaled (0-10) | =RAND()*10 | 7.42130 |
| Scaled (1-100) | =RAND()*99+1 | 73.57087 |
RAND spits out decimals: 0.74213, scalable to ranges. It’s a randomness spark.
