Understanding how your cryptocurrency investments are performing is essential—whether you're a seasoned trader or just beginning your journey in digital assets. CoinMarketCap (CMC) offers a powerful Portfolio Tracker that delivers accurate, real-time insights into your profits and losses. But how exactly does it work?
In this guide, we’ll break down the methodology behind CMC’s profit calculations, so you can confidently interpret your portfolio metrics and make smarter investment decisions.
What Is All-Time Profit?
At the core of your portfolio performance is all-time profit—the ultimate measure of your crypto investment success.
Simply put:
- It reflects the total difference between what you’ve invested and your portfolio’s current value.
- It combines both realized profits (from coins you’ve sold) and unrealized profits (from coins you still hold).

Realized vs. Unrealized Profit: Key Differences
To fully grasp your returns, it's important to understand these two fundamental components:
Realized Profit
- This is actual profit from selling cryptocurrency.
- Once you sell, the gain or loss becomes "locked in."
- Example: Selling Bitcoin at a higher price than you bought = realized gain.
Unrealized Profit
- This is paper profit—your potential gain based on current market prices.
- It changes constantly as prices fluctuate.
- Example: Holding Ethereum that has increased in value since purchase = unrealized gain.
Your total performance is the sum of both. Only when you sell does unrealized profit convert to realized.
Behind the Scenes: How CMC Tracks Your Data
CMC automatically processes every transaction and market update to deliver accurate results. Here’s what we monitor:
✅ Purchases
- Amount of cryptocurrency acquired
- Price per unit at time of purchase
- Associated buying fees
✅ Sales
- Quantity sold
- Sale price per unit
- Transaction or platform fees
✅ Current Market Prices
- Real-time data feeds ensure up-to-the-minute valuations
- Used to calculate unrealized gains/losses for holdings
With this data, our system computes key metrics that power your Portfolio Tracker.
The Math Behind Your Returns
Let’s dive into the formulas used to determine your portfolio’s performance.
1. Average Buy Price
For each cryptocurrency:
Total amount spent (excluding fees) ÷ Total quantity purchased
This helps identify whether you're above or below market value.
2. Cost Basis
The full investment cost including fees:
Σ(Buy Price × Buy Amount) + Σ(Buying Fees)
This forms the foundation for calculating both realized and unrealized profits.
3. Average Buy Cost (Including Fees)
Total Cost (with fees) ÷ Total Quantity Purchased
This gives a true reflection of your break-even point per coin.
4. Realized Profit
Calculated upon each sale:
(Selling Price × Amount Sold) − [(Cost Basis / Total Bought) × Amount Sold] − Selling Fees
All individual sale profits are aggregated into your total realized profit.
5. Unrealized Profit
For coins still in your wallet:
(Current Market Price × Amount Held) − [(Cost Basis / Total Bought) × Amount Held]
This fluctuates with price movements.
6. All-Time Profit
Realized Profit + Unrealized Profit
This is your net gain or loss across all activity.
7. P&L% (Profit and Loss Percentage)
All-Time Profit ÷ Cost Basis
A crucial metric for evaluating efficiency—how much return you’ve generated per dollar invested.
Real-World Example: Step-by-Step Calculation
Let’s walk through a practical scenario involving Bitcoin:
- Buy 1 BTC at $10,000**, with a **$50 fee
- Buy another 0.5 BTC at $6,000**, with a **$30 fee
- Sell 0.75 BTC for $12,000**, with a **$60 fee
- Current BTC price: $18,000
Calculations:
- Cost Basis: $10,000 + $6,000 + $50 + $30 = $16,080
- Total BTC Purchased: 1.5 BTC
- Average Buy Cost: $16,080 ÷ 1.5 = **$10,720/BTC**
Realized Profit:
($12,000) − (0.75 × $10,720) − $60 = **$3,900**
Unrealized Profit:
(0.75 BTC × $18,000) − (0.75 × $10,720) = $5,460
All-Time Profit:
$3,900 + $5,460 = $9,360
P&L%:
$9,360 ÷ $16,080 ≈ 58.21%
You’ve earned nearly 58% return on your total investment so far.
How Transfers Affect Your Portfolio
Transfers don’t count as buys or sells, but they influence your holdings:
Scenario:
- Transfer in 2 BTC at market price of $62,000/BTC
- Sell 1 BTC for $30,000**, with **$10 fee
- Transfer out remaining 1 BTC
After sale:
- Unrealized Profit: $62,000 (value of remaining BTC)
- Realized Profit: $30,000 − $10 = $29,990
- All-Time Profit: $62,000 + $29,990 = $91,990
After transfer out:
- No coins left → Unrealized Profit = $0
- All-Time Profit = Only realized portion: $29,990

Transfers update your position size but don’t trigger profit events unless followed by a sale.
Tips for Getting the Most from Your Portfolio Tracker
Maximize accuracy and insight with these best practices:
🔹 Keep transactions updated – The more complete your history, the better the analysis.
🔹 Use tags to categorize – Label investments by strategy (e.g., “long-term,” “DeFi”) for deeper insights.
🔹 Review regularly—but stay calm – Markets are volatile; focus on trends over time.
🔹 Focus on percentages – A 10x return on a small amount may look exciting, but a 30% gain on a large holding often matters more.
Frequently Asked Questions
Q: Why did my profit change even though I didn’t trade?
A: Your unrealized profit changes with market prices. Even without selling, the value of your holdings fluctuates daily.
Q: Are transaction fees included in profit calculations?
A: Yes. Buying fees increase your cost basis; selling fees reduce your proceeds—both improve accuracy.
Q: Can I view performance over specific periods?
A: Absolutely! You can analyze returns over 24h, 7d, 30d, or custom timeframes to assess short- and long-term trends.
Q: Does CMC support multiple wallets or exchanges?
A: Yes. You can link various accounts or manually add transactions for a unified portfolio view.
Q: Is my data secure?
A: CMC does not store private keys or personal credentials. Your portfolio data remains private and encrypted.
