How to use the percentage generator
- Set the lowest and highest percent, or tap a preset band such as 50 to 100.
- Choose the decimal places, from whole percentages to six place precision.
- Set how many values you need, then press Generate random percentages.
Percent, decimal and fraction in one view
A percentage is just a number out of one hundred, so every value this tool draws has a decimal and often a neat fraction form. The common conversions are worth keeping to hand.
| Percent | Decimal | Fraction |
|---|---|---|
| 10% | 0.1 | 1/10 |
| 12.5% | 0.125 | 1/8 |
| 25% | 0.25 | 1/4 |
| 33.3% | 0.333 | about 1/3 |
| 50% | 0.5 | 1/2 |
| 75% | 0.75 | 3/4 |
| 100% | 1.0 | 1/1 |
To move from percent to decimal, divide by 100. To go the other way, multiply by 100. The CSV export writes plain numbers without the percent sign, so the values drop straight into formulas.
How precision changes the pool
The decimal places setting decides how many distinct percentages exist between your bounds. Across the full 0 to 100 band, whole percentages give 101 possible values, one decimal place gives 1,001 and two places give 10,001. That matters for the no repeats option: a narrow band at low precision can run out of distinct values, and widening either setting restores the headroom.
Where random percentages earn their keep
Random percentages are the natural shape for rates: mock conversion rates for a dashboard demo, discount levels for price testing, completion percentages for progress bar states, probability inputs for classroom exercises, and score distributions for grading system tests. Because the draw is uniform, each value in your band is equally likely, and the summary line shows the batch average so you can confirm it sits near the middle of the band.

Frequently asked questions
What does the percentage generator do
It draws random percentage values between the lowest and highest percent you set, shown with a percent sign and the precision you choose.
Can I change the precision
Yes. Set decimal places to 0 for whole percentages like 64%, or 1 and above for values like 63.7%.
Can I limit the range
Yes. Use the two fields or a preset, for example 90 to 100 for a pass band, or 0 to 50 for the lower half.
Can I get unique percentages
Yes. Tick no repeats for a set with no duplicate values at your chosen precision.
Is it free
Yes, free and with no sign up. Every draw runs in your browser and nothing you enter leaves your device.
