Tool guide
What is a trade’s break-even price?
Break-even is the price where net P&L is approximately zero under the selected cost model. Spread, commission, swap and slippage can shift that level; however, if the entered execution price already embeds the bid/ask spread, entering the same spread again would double-count it.
Logic / formula
Break-even = entry ± total costs converted into price units. Cash-to-price conversion must match the actual contract and position used in the trade.
Read the output
Read break-even price with the cost breakdown and verify that no cost is already embedded in entry and entered a second time.

Worked example
Example
A Buy trade with spread and round-turn commission
On a long trade, total costs shift break-even above entry; the exact move depends on spread, commission and other costs.
On a long trade, total costs shift break-even above entry; the exact move depends on spread, commission and other costs.
How to read the result
The headline number must be read with assumptions and warnings. Out-of-bound values should be corrected before trading.
Break-even distance shows how far price must move in your favor before costs are recovered. Use cost decomposition to identify which component contributes most to the shift.

Common mistakes and limitations
- Confusing risk with margin or potential profit
- Ignoring costs and rounding
- Using the wrong unit or currency
- Future slippage and swap are not known in advance and are broker-specific. If spread is already embedded in executed entry and also entered separately, double counting can occur.
Frequently asked questions
Why is break-even above entry on a long trade?
Because costs must be recovered before the trade reaches net zero.
Should I enter both spread and commission?
Yes if both are separate real costs on the account, but avoid counting a cost already embedded in executed entry.
Do I need swap for an intraday trade?
It may be zero if the position never crosses the broker’s financing cutoff; check account rules.
