Break-even Calculator

How the calculation works

Round-trip fees are spread across shares to get a fee-per-share hurdle, then added to entry. The resulting break-even price is the exit level at which net P&L is roughly zero before taxes and slippage.

Formula & example

Break-even = entry + (total fees ÷ shares)

Entry $30, 100 shares, $10 fees → break-even $30.10.

Why use this calculator

Without a fee-aware break-even, targets set exactly at entry can still lose money. The hurdle price is the first number a scale-out or stop plan should clear.

When to use it

Use when fees, commissions, or explicit transaction costs are large enough relative to share count that a tiny price move is not enough to get flat.

Tips for accurate results

• Use round-trip fees if you will exit.
• For shorts, fees still raise the hurdle rate.
