Cryptocurrency markets are dynamic, fast-moving, and operate 24/7—making it essential for investors to understand how price changes are measured. One of the most commonly referenced metrics in trading is the price change percentage, often labeled as “24-hour change” or simply “price change.” But how exactly is this figure calculated? What factors influence its accuracy? And why might the same cryptocurrency show different change percentages across platforms?
In this guide, we’ll break down the mechanics behind cryptocurrency price change calculations, explore different time-based standards used by exchanges, and help you interpret these figures with greater confidence—especially if you're new to digital asset investing.

Understanding the Basics of Cryptocurrency Price Change
When browsing a cryptocurrency exchange or market tracker, you'll frequently see a percentage next to each digital asset—green if positive, red if negative. This number reflects the percentage change in price over a specific period, typically the last 24 hours.
For example:
- If Bitcoin is listed at a +5% change, it means its current price is 5% higher than it was 24 hours ago.
- A -3% change indicates a drop in value over the same timeframe.
This metric helps traders quickly assess momentum, volatility, and market sentiment without diving into raw price charts.
But here’s what many beginners miss: not all exchanges calculate this percentage the same way. The variation in methodology can lead to slight (or sometimes significant) differences in reported values—even for the same asset on different platforms.
How Is the Percentage Change Calculated?
The general formula for calculating cryptocurrency price change is straightforward:
Price Change (%) = [(Current Price - Previous Price) / Previous Price] × 100Let’s illustrate this with an example:
Suppose today at 12:00 PM, EOS is trading at $23. Exactly 24 hours earlier, at 12:00 PM the previous day, EOS was priced at $25.
Using the formula:
($23 - $25) / $25 = -0.08 → -8%So, the 24-hour price change would be displayed as -8%, indicating an 8% decline.
This method—comparing the current price to the price exactly one day prior—is widely adopted because it aligns with global trading cycles and avoids time-zone bias.
Alternative Calculation Methods
Some platforms use fixed time windows instead of rolling 24-hour periods. For instance:
- Huobi (now HTX) has historically used Beijing time midnight (00:00) as the starting point for daily price change calculations.
- So if you check the “daily change” at 3:00 PM on November 19, it compares the current price to the price at 00:00 on that day—not 24 hours ago.
This approach creates a calendar-day-based metric, similar to how traditional stock markets report daily gains. However, since crypto trades non-stop, this method may not capture full market cycles and can lag behind real-time trends.

Why Do Different Exchanges Show Different Percentages?
You might notice that Bitcoin shows a +6.2% change on one platform but only +5.8% on another. Several factors contribute to these discrepancies:
- Different Timeframes: As explained, some exchanges use rolling 24-hour windows; others use fixed daily resets.
- Price Sources: Exchanges calculate changes based on their own trading data. Since prices vary slightly between markets due to liquidity and order book depth, so do the resulting percentages.
- Data Update Frequency: Some platforms refresh metrics every few seconds; others may have delays.
- Trading Pairs: The change percentage might differ depending on whether it's measured against USD, USDT, or BTC.
These nuances matter—especially when making time-sensitive decisions.

Frequently Asked Questions (FAQ)
Q: What does "24-hour change" mean in crypto?
A: The "24-hour change" refers to the percentage increase or decrease in a cryptocurrency’s price over the past 24 hours. It's calculated by comparing the current price to the price exactly one day ago, using the formula: ((Current Price - Previous Price) / Previous Price) × 100.
Q: Why is my crypto showing different price changes on different apps?
A: Different platforms may use varying calculation methods—some use rolling 24-hour windows, while others reset at midnight (based on UTC or local time). Additionally, each exchange uses its own traded prices, which can vary slightly due to supply and demand imbalances.
Q: Can a crypto have a positive price change but still lose value in fiat terms?
A: Not directly—if the price in fiat (like USD) increases, the percentage change will reflect that gain. However, if inflation or opportunity cost is considered (e.g., other assets performed better), an investor might perceive a “loss” even with nominal gains.
Q: Is the 24-hour change based on opening and closing prices like in stocks?
A: Not always. Unlike traditional markets with defined open/close times, crypto trades continuously. Most exchanges use a rolling window, meaning there’s no fixed “opening” price—it’s simply the price from 24 hours ago at that exact moment.
Q: How often is the price change updated?
A: On major platforms like OKX, Binance, or Coinbase, the 24-hour change is updated in real-time—usually refreshed every few seconds as new trades occur.
Q: Should I base my trading decisions solely on 24-hour change?
A: While useful for spotting momentum, this single metric shouldn’t drive investment choices alone. Combine it with volume analysis, order book depth, news events, and longer-term trend analysis for more informed decisions.

Final Thoughts: Use Price Change as a Tool, Not a Rule
Understanding how cryptocurrency price change is calculated empowers you to interpret market data more accurately. Whether you're monitoring short-term swings or evaluating long-term trends, knowing whether an exchange uses a rolling 24-hour window or a fixed daily reset helps you avoid confusion and make better-informed decisions.
Remember: no single metric tells the whole story. The 24-hour change is best used alongside other indicators—such as trading volume, market cap movement, and on-chain activity—to form a complete picture of an asset’s performance.
As the crypto ecosystem evolves, so too will data transparency and standardization. Until then, being aware of how your chosen platform calculates key metrics gives you a competitive edge—one percentage point at a time.
