How to Use the Calculator
Follow these steps to calculate your break-even point and average purchase price:

Understanding Break-Even Point
The break-even point is the stock price at which you recover all costs, including fees, without profit or loss.
- Formula: Break-Even Price = (Total Cost + Total Commission + Total Tax) / Total Shares
- It accounts for all expenses related to the purchase.
- Use this to determine the minimum selling price to avoid a loss.
Understanding Average Purchase Price
The average purchase price is the weighted average cost per share across multiple purchases.
- Formula: Average Price = Total Cost / Total Shares
- It reflects the effective cost per share before fees.
- Useful for tracking investment performance over multiple transactions.
Factors Affecting Calculations
Several factors influence the break-even price and average purchase price:
Commission Fees
Brokerage fees increase the total cost of ownership.
- Vary by broker (e.g., flat fee or per-share fee).
- Higher fees raise the break-even price.
Tax Fees
Taxes, such as transaction taxes, impact total costs.
- Depend on local regulations (e.g., 0.5% in some markets).
- Included in break-even calculations but not average price.
Number of Purchases
Multiple transactions affect the average price calculation.
- More purchases require accurate input for each action.
- Total cost and shares are aggregated from individual purchases.
Typical Stock Trading Fees
Fees vary by market and broker (as of general trends):
Commission Fees
- $0 - $10 per trade (common with online brokers).
- Some charge per share (e.g., $0.005).
Tax Fees
- 0% - 1% of transaction value (e.g., SEC fees in the U.S., stamp duty elsewhere).
Tips for Using the Calculator
- Ensure all costs (commissions, taxes) are included for each purchase action for accurate break-even results.
- Verify shares, costs, and fees for each purchase action against your trading records.
- Use the "Add Purchase" button to input multiple buys accurately.
- Consult your broker or financial advisor for exact fee structures.
