Example Break-Even Stock Calculation
Suppose you buy 100 shares at $50 and pay $20 in combined buying and selling costs. Before taxes, the break-even price is about $50.20.
If a tax assumption is added, the required sale price can rise because part of the gain is assumed to be reduced by tax.
- Enter share count and purchase price.
- Add buy and sell commissions or fees.
- Enter a tax assumption only if you want a simplified tax-adjusted example.
- Review break-even price and profit target price.
Break-Even Cost Comparison
Break-even price rises when fees and tax assumptions increase. This example uses 100 shares purchased at $50.
| Purchase Price | Estimated Costs | Tax Assumption | Approx. Break-Even |
|---|---|---|---|
| $50.00 | $0 | 0% | $50.00 |
| $50.00 | $20 | 0% | $50.20 |
| $50.00 | $20 | 15% | $59.06 |
How to Interpret the Result
Break-even price is the estimated sell price needed to cover the entered costs.
The profit target is a simple margin above break-even, not a forecast or valuation estimate.

Break Even Stock FAQ
What is break-even price?
Break-even price is the sell price needed to cover purchase cost, fees, commissions, and selected tax assumptions.
Why include selling costs?
Selling commissions, fees, and tax assumptions can raise the price needed to avoid a loss.
Does this include dividends?
No. If dividends reduce your effective cost, adjust your inputs manually for an educational example.
Is this tax advice?
No. The tax field is only a simplified assumption and does not reflect personal tax rules.
How do fees affect break-even price?
Fees increase the total cost that must be recovered, so the required break-even sell price can rise even if the purchase price stays the same.
Can this calculate a profit target too?
Yes. The desired profit margin input estimates a target price above the calculated break-even price.
