CoinTracking calculates your average purchase price to help you understand whether you’d make a profit or loss if you sold a specific coin today. It’s a useful way to visualize your break-even point per asset.

How Is the Average Purchase Price Calculated?

The calculation compares your total investment in a coin against any portions you’ve sold. The formula is:

(Buy 1 × Price) + (Buy 2 × Price) + … − (Sell 1 × Purchase Price) − (Sell 2 × Purchase Price) …

The result is your average purchase value per remaining unit of the coin, shown in fiat currency.

• If the current market price is higher, the row turns green, indicating a profit.

• If it’s lower, the row turns red, indicating a loss if you sold now.

Why Is My Purchase Price Negative?

A negative value means you've already recovered more than you invested. This happens when your earlier sales generated more profit than your total cost basis.

Example:

You buy 1,000,000 DVC for $100.
Later, the price rises and you sell 500,000 DVC for $200.
You’ve now made $100 profit, and still hold 500,000 DVC.
Even if the price goes to zero, you’re still up overall—so your average purchase price becomes negative.

This is not a bug—it's a sign you’ve already secured gains on that position.

What Does “Too Low” Mean?

When your remaining amount of a coin is extremely small, the average price needed to break even can become astronomically high. For example, you might need to sell for several million or even billions per coin to offset previous losses.

Rather than show unrealistic or misleading numbers, CoinTracking displays “too low” when:

• The break-even price is mathematically accurate but meaningless in real-world terms

• Your remaining balance is so small that price tracking is no longer useful

Summary

If you see a negative or “too low” average purchase price, it usually means:

• You’ve already made a profit (negative = good), or

• You only hold a tiny leftover amount (too low to calculate meaningfully)

These are normal and expected behaviors in the way CoinTracking calculates portfolio performance.
