PERCENTAGE CALCULATOR
What is the Percentage Calculator?
Percentage calculator (%) can become a very useful trading tool that will help you find out how much exactly this or that token retraced or grew in price historically, measure possible price swings, and plan trades.

Why percentage maths matters in trading
Percentage calculations are ubiquitous in trading and investing. Whether you are calculating your profit or loss on a position, estimating how far an asset has fallen from its all-time high, determining the percentage change between two prices, or figuring out what price represents a specific percentage recovery from a drawdown, accurate percentage math is foundational to clear thinking about market positions.
The three calculations this tool covers
This calculator handles the three most common types of percentage calculations traders need. The first is a straightforward percentage of a number — 'what is X% of Y?' — useful for position sizing and fee calculations. The second is percentage change between two values — 'by what percentage did the price change?' — useful for performance measurement. The third is reverse percentage — 'what value represents X% more or less than Y?' — useful for calculating target prices, stop-losses, and recovery levels.
The asymmetry between losses and recovery
One common source of confusion in crypto is the asymmetry between drawdown and recovery percentages. An asset that falls 50% needs to rise 100% to return to its starting level. An asset that falls 80% needs to rise 400%. This asymmetry means the severity of a drawdown is far more consequential for long-term portfolio performance than it initially appears — and it makes position sizing and stop-losses critical tools for managing long-term compounding.
Frequently Asked Questions
What can this calculator work out?
It handles the three percentage calculations traders need most: what a given percentage of a number is, what percentage one number is of another, and the percentage change between two values. Each takes a different form and they are easily confused.
Why does a 50% loss need a 100% gain to recover?
Because the two percentages are calculated from different bases. Losing half of 100 leaves 50, and returning to 100 from there requires gaining 50, which is 100 percent of what remains. The loss is measured against the original figure and the recovery against the reduced one.
How much do I need to recover from an 80% drawdown?
400 percent. An 80 percent fall leaves 20 percent of the original value, and multiplying that back up to 100 requires a fivefold increase. This asymmetry is why avoiding deep drawdowns matters more to long-run results than capturing large gains.
How do I calculate percentage profit on a trade?
Subtract the entry price from the exit price, divide by the entry price, then multiply by 100. Dividing by the entry rather than the exit is the step most often reversed, and reversing it understates gains and overstates losses.
What is the difference between percentage change and percentage points?
Percentage points measure absolute difference between two percentages, while percentage change measures the relative difference. A funding rate moving from 2 to 3 percent has risen one percentage point, which is a 50 percent change. Confusing them is a common source of error.
