Free Trade Calculation Tools
The arithmetic behind a single trade, done properly
What the trade actually made after fees, what the ratio requires of your win rate, where the position stops losing money, and how much room a leveraged position has before a call.
Profit and Loss Calculator
Calculate the result of a trade after fees, with the return percentage, the price move and the result expressed as an R multiple.

The R-multiple expresses the result as a multiple of the risk originally taken, which is the only way to compare trades of different sizes.
Fees are included in the net figure and in the break-even price, because a trade that recovers the entry price has not recovered its cost.

Four questions come up on nearly every trade, and each has a definite answer that most platforms only partly display: the net result after costs, the win rate a risk to reward ratio demands, the price at which the position is neutral, and how far price can move against a leveraged position before it is closed for you.
These calculators answer them from figures you enter. None of them has price data, none predicts anything, and nothing you type is transmitted anywhere.

Why use TradingCalculatorTools
Net, not gross
Every round trip pays commission twice and crosses the spread. On short-term trades that is a large share of the gross result.
The ratio and the win rate together
A three-to-one ratio at a twenty percent win rate loses. The break-even win rate is the number that makes a ratio meaningful.
Break-even is beyond the entry
Exiting at your entry price is a loss. Financing on a position held for weeks moves that line further than commission does.
Effective leverage, not advertised leverage
What matters is the position you actually hold against your equity - and how far price can move before the cushion is gone.
How it works
- Work out the net result of a closed trade, including fees, and convert it to an R multiple.
- Screen a setup on its ratio, then check that ratio against your measured win rate.
- Find the break-even price before deciding whether a small target is worth taking.
- Check effective leverage and the adverse move to a call before adding to a position.
Frequently asked questions
Do these tools connect to my broker or an exchange?
No. There is no market data feed, no API connection and no account. Every figure comes from values you enter, which is also why nothing you type leaves your browser.
What is an R multiple?
A result expressed as a multiple of the amount risked. A trade that made twice what it risked is +2R, whatever the position size, which is what makes trades comparable across a whole record.
Why is my break-even price above my entry?
Because getting in cost something and getting out will cost something more. Closing at the entry price is always a small loss once fees are counted.
What risk to reward ratio should I use?
There is no correct figure - it depends entirely on your win rate. High win rate strategies work at low ratios and low win rate strategies need high ones.
Is any of this financial advice?
No. These calculators are for informational and educational purposes only. Nothing here recommends a trade, an instrument, a strategy or a level of risk.
