What Is the Break-Even Price?

The break-even price is the price at which an investment or sale results in neither profit nor loss. For stock trades, it is the purchase price plus any commissions and fees. For options trades, it accounts for the premium paid and the strike price. For businesses, it is the minimum selling price that covers all costs.

Knowing your break-even price before entering a trade or pricing a product is fundamental to sound financial decision-making. It sets the baseline against which you measure success and defines the minimum outcome needed to avoid losing money.

Break-Even Price Formulas

Long Call Break-Even
Break-Even = Strike Price + Premium Paid + Fees per Share
Where:
Strike Price = The call option strike price
Premium Paid = Premium paid per share for the call
Fees = Commissions allocated per share
Long Put Break-Even
Break-Even = Strike Price - Premium Paid - Fees per Share
Where:
Strike Price = The put option strike price
Premium Paid = Premium paid per share for the put
Fees = Commissions allocated per share
Covered Call Break-Even
Break-Even = Stock Purchase Price - Premium Received
Where:
Stock Purchase Price = Price paid per share
Premium Received = Call premium collected per share
Stock Trade Break-Even
Break-Even = Purchase Price + (Total Commissions / Number of Shares)
Where:
Purchase Price = Price paid per share
Total Commissions = All trading fees and commissions
Number of Shares = Total shares purchased
Options Break-Even Calculation
Given
Strike Price
$50
Premium Paid
$3.00 per share
Commission
$0.65 per contract
Contracts
1 (100 shares)
Calculation Steps
  1. 1Total premium cost = $3.00 × 100 = $300
  2. 2Total commission = $0.65
  3. 3Total position cost = $300 + $0.65 = $300.65
  4. 4Fee per share = $0.65 / 100 = $0.0065
  5. 5Long Call Break-Even = $50 + $3.00 + $0.0065 = $53.0065
  6. 6Long Put Break-Even = $50 - $3.00 - $0.0065 = $46.9935
  7. 7The stock must rise above $53.01 (call) or fall below $46.99 (put) to profit
Result
For a long call at the $50 strike with a $3.00 premium, the stock must trade above $53.01 at expiration for the trade to be profitable. For a long put, the stock must fall below $46.99.

Break-Even Price for Product Sales

For businesses selling physical or digital products, the break-even price is the minimum selling price that covers all costs. This includes the cost of goods sold, allocated fixed costs per unit, and any per-unit fees or commissions.

Product Break-Even Price
Break-Even Price = Variable Cost + (Fixed Costs / Expected Units)
Where:
Variable Cost = Per-unit variable costs
Fixed Costs = Total fixed costs for the period
Expected Units = Expected sales volume

How to Calculate Your Break-Even Price

1
Identify All Costs
List every cost: purchase price, commissions, fees, taxes, shipping. For options, include the premium. For products, include COGS and overhead allocation.
2
Calculate Total Investment
Sum all costs to determine your total outlay. This is the amount you need to recover to break even.
3
Determine the Break-Even Price
Divide total cost by the number of units (or shares). This is the minimum price per unit at which you recover all costs.
4
Add a Profit Buffer
Price above break-even to earn a profit. A common approach is to add your target profit margin on top of the break-even price.
!
Break-Even Is Not Profit

The break-even price is your floor, not your target. Pricing at exactly break-even means you earn zero profit. Always price above break-even to account for unexpected costs, market fluctuations, and to generate returns that justify the risk taken.
