Free trading calculators

The arithmetic every trade needs, worked out in your browser. No account, no sign up, and nothing you type leaves the page.

These are calculators. They tell you what a number is. They do not tell you what to trade, and nothing here is financial advice.

Position size calculator
Work out the position size in lots that puts a fixed percentage of your account at risk over a given stop distance, with no account and no sign up.
Pip value calculator
Find what one pip is worth in money for any pair and position size, in the quote currency or converted into your account currency.
Profit and loss calculator
See what a move from one price to another is worth, in pips and in money, for a long or a short position of any size.
Margin calculator
Work out how much margin a position needs at a given leverage, in the pair's base currency, before you open it.
Lot size converter
Convert between lots and units for standard, mini and micro lots, in either direction.
Risk to reward calculator
Measure the distance from entry to stop against the distance from entry to target, and read the ratio between them.
Drawdown recovery calculator
See what percentage gain it takes to get an account back to where it started after a loss of a given size.

Free, with no sign up

Every calculator works instantly in your browser. No account, no limits, and nothing to install. Size your position, check your pip value or plan your risk as often as you like, before every trade.

When you want more than the numbers, the FXSynapse scanner reads your chart screenshot and marks the structure and key levels for you. Try the scanner free. The calculators stay free either way.

If a word here is new

The glossary explains pip, lot, margin and the rest in one sentence each, and the guides walk through reading a chart from the start.
