What is Stock Break-Even Price Calculator?

Every stock trade has a break-even point — the minimum price you need to sell at to cover your purchase cost and all associated fees. Knowing this number before you enter a trade is essential for setting realistic profit targets and managing risk. Our stock break-even calculator computes your exact break-even price per share, factoring in your buy price, number of shares, and both buy and sell commissions. It supports percentage-based and fixed-dollar commission models. You can also enter a target profit amount to see the sell price needed to achieve your goal. Whether you're a day trader managing tight margins or a long-term investor planning exits, understanding your break-even point helps you make disciplined, data-driven decisions rather than emotional ones.

Steps:

  1. Enter your buy price per share and number of shares.
  2. Set your broker's buy and sell commission rates.
  3. Optionally enter a target profit amount.
  4. Review your break-even price and target sell price.
  5. Use the scenario panel to see how different commission levels affect your break-even.

Formula

Buy Commission Amount = Buy Price × Shares × Buy Commission % (or fixed) Sell Commission Amount = Buy Price × Shares × Sell Commission % (or fixed) Total Costs = Buy Price × Shares + Buy Commission + Sell Commission Break-Even Price = Total Costs ÷ Shares Target Price = (Total Costs + Target Profit) ÷ Shares Min Sell Per Share = Break-Even Price

Use Cases

  • Day traders calculating minimum profitable exit prices
  • Swing traders setting realistic profit targets
  • Long-term investors understanding cost basis thresholds
  • New traders learning the impact of commissions on returns

Key Benefits

  • Know your exact break-even before entering any trade
  • Set informed profit targets with the target price feature
  • See how commissions impact your minimum required return
  • Compare different commission models to optimize costs

Pro Tips

  • Always calculate break-even before entering a trade
  • Set profit targets at least 2× your break-even distance
  • Use larger position sizes to minimize fixed commission impact
  • Compare brokers based on total cost, not just commission rate

Common Mistakes to Avoid

  • Assuming break-even equals the buy price
  • Ignoring sell-side commissions in break-even calculations
  • Setting profit targets without knowing the break-even first
  • Not accounting for fixed fees on small positions

Key Terms Explained

Break-Even Price: Minimum sell price to cover all costs
Target Price: Sell price needed to achieve desired profit
Total Costs: Purchase cost plus all commissions and fees

Example

You buy 50 shares at $100 each with 1% buy commission and 1% sell commission. Buy Commission = $5,000 × 1% = $50. Sell Commission = $5,000 × 1% = $50. Total Costs = $5,000 + $50 + $50 = $5,100. Break-Even Price = $5,100 ÷ 50 = $102 per share. You need the stock to rise at least 2% just to break even. For a $500 target profit: Target Price = ($5,100 + $500) ÷ 50 = $112.

Frequently Asked Questions

What is the break-even price in stock trading?
The break-even price is the minimum price per share you need to sell at to cover your entire investment cost — including the purchase price and all transaction fees (buy and sell commissions). Selling below this price means a loss; selling above it means a profit. It's calculated as: (Total Purchase Cost + All Commissions) ÷ Number of Shares.
Why is the break-even price higher than my buy price?
Because commissions and fees add to your total cost. Even with a $0 commission broker, there may be regulatory fees, spread costs, and slippage. For example, if you buy at $100/share with $10 total commissions on 50 shares, your break-even is $100.20 — you need the stock to rise at least $0.20 just to cover fees.
How do commissions affect my break-even point?
Higher commissions push your break-even price higher. With percentage-based commissions, larger positions have proportionally higher break-evens. With fixed commissions, smaller positions are disproportionately affected — a $10 fee on 10 shares adds $1/share to break-even, but only $0.10/share on 100 shares.
Should I set my target price above break-even?
Absolutely. Your target price should be comfortably above break-even to provide a margin of safety and meaningful profit. A common approach is to set targets at key resistance levels or based on your risk-reward ratio (e.g., 2:1 or 3:1). The calculator shows both break-even and target price with profit.
Does this calculator account for taxes?
No, this calculator focuses on pre-tax break-even. Capital gains taxes vary by jurisdiction, holding period, and income level. To account for taxes, add your estimated tax rate to your target profit. For example, if your pre-tax break-even is $105 and you expect 15% capital gains tax, factor that into your target.
How does the target profit feature work?
Enter a desired profit amount in dollars, and the calculator shows the sell price needed to achieve that profit after covering all costs. Target Price = (Total Costs + Target Profit) ÷ Shares. This helps you set realistic profit goals before entering a trade.
What if I'm dollar-cost averaging?
For DCA positions with multiple buy prices, use the Stock Average Down Calculator first to find your weighted average cost basis, then use that average price as the buy price in this break-even calculator.
Is break-even analysis important for long-term investors?
Yes. Even long-term investors should know their break-even price to understand the minimum performance needed. It helps set realistic expectations and informs decisions about whether to hold, add to, or exit a position. It's especially useful when evaluating whether a declining stock is still above your break-even.
How do I reduce my break-even price?
You can reduce break-even by: (1) using a lower-commission broker, (2) buying in larger quantities to spread fixed fees, (3) negotiating lower commission rates with your broker, or (4) averaging down at lower prices (though this increases total capital at risk).
Can break-even change after I buy?
The break-even price is fixed at purchase based on your buy price, shares, and commissions. It only changes if you: add more shares (averaging down/up), receive dividends (which effectively lower your cost basis), or your broker changes fee structures.
What about options break-even?
Options have a different break-even calculation. For calls: Break-Even = Strike Price + Premium Paid. For puts: Break-Even = Strike Price − Premium Paid. This calculator is designed for stock positions, but the concept of covering all costs applies to options too.
