- Generate again for another reading.
What is a percentage?
A percentage is a number out of 100: 25% means 25 out of 100, or one quarter. This generator picks a whole percentage from 0% to 100%, with every value — 0, 1, 2, all the way to 100 — equally likely.
What can you do with it?
- Probability demos — show a random 'chance' value in a lesson or talk.
- Games of chance — roll a percentage for hit chances, loot drops or dares.
- Surveys & mock-ups — fill a chart or slide with placeholder percentages.
- Progress-bar tests — feed a random fill level into a UI while building it.
- Quick calls — settle a 'how likely' question with a single tap.
How it works
Each reading is drawn with your browser's cryptographically secure randomness across the whole 0 to 100 scale, so every percentage is equally likely and unbiased. Nothing is sent to a server.
Frequently asked questions
- How do I get a random percentage?
- Just tap Generate — you get a random whole percentage from 0% to 100%, with every value equally likely.
- What's the range?
- From 0% to 100%, with each value equally likely.
- Can I get a random percentage with decimals?
- This tool returns whole percentages. If you need decimals, use the random decimal generator and set the range to 0 to 100.
- Can I get unique percentages with no repeats?
- Each tap is independent, so a value can come up again. For a set of unique numbers with no duplicates, use the random number list generator with repeats off.
- What can I use a random percentage for?
- Probability demos, 'how likely is it' prompts, survey and poll mock-ups, progress-bar tests, and quick chance calls in games.
- Is the result truly random?
- Yes. Each result uses your browser's cryptographically secure randomness (a CSPRNG), so every value is independent, unbiased and unpredictable.
- Is it free and private?
- Completely free, no sign-up. Everything runs in your browser, so nothing you type is uploaded.
