Stock Average Down Calculator

Use this calculator to determine your new average share price and total investment after purchasing additional shares of a stock at a different price. This strategy, known as "averaging down," can reduce your overall cost basis.

Understanding the Stock Average Down Strategy

The "average down" strategy is a common tactic used by investors to reduce the average cost of shares they own in a particular stock. This occurs when an investor buys more shares of a stock after its price has fallen. By purchasing additional shares at a lower price, the overall average price paid for all shares decreases.

How Averaging Down Works

Imagine you bought 100 shares of Company X at $50 per share, for a total investment of $5,000. If the stock price then drops to $40 per share, and you decide to buy another 100 shares, your new total investment would be:

• Initial Investment: 100 shares * $50/share = $5,000
• New Investment: 100 shares * $40/share = $4,000
• Total Shares: 100 + 100 = 200 shares
• Total Investment: $5,000 + $4,000 = $9,000
• New Average Price: $9,000 / 200 shares = $45/share

As you can see, your average price per share has dropped from $50 to $45. This means the stock only needs to recover to $45 for you to break even, rather than $50. If the stock eventually rises above $45, you will start making a profit sooner.

Why Investors Average Down

Investors typically employ this strategy when they have strong conviction in a company's long-term prospects, despite a recent price decline. They believe the dip is temporary and that the stock will eventually rebound. Averaging down allows them to:

• Reduce Cost Basis: Lowering the average purchase price per share.
• Quicker Break-Even: The stock doesn't need to climb as high to reach the break-even point.
• Amplify Gains: If the stock recovers significantly, the larger number of shares at a lower average cost can lead to greater overall profits.

Risks and Considerations

While averaging down can be a powerful strategy, it's not without risks:

• "Throwing Good Money After Bad": If the stock continues to decline because of fundamental problems with the company, you could end up losing more money. It's crucial to re-evaluate your investment thesis before averaging down.
• Opportunity Cost: The capital used to average down could potentially be invested in other, better-performing assets.
• Market Conditions: A broad market downturn might mean that even fundamentally sound companies could take a long time to recover.
• Emotional Decisions: It's important to make averaging down decisions based on thorough analysis, not panic or hope.
