Position size, pip value, margin, profit and loss, and live currency conversion — five calculators on a single page. Free, no signup, and every calculation runs in your own browser.
All five calculators are on this page — slide down to the one you need, or jump straight to it.
Calculator 01 of 05
Work out the lot size that keeps a losing trade inside the risk you are prepared to take. Enter your balance, the risk per trade and the stop distance — the pip value and the currency conversion are filled in for you.
Fill in the fields on the left - the result updates as you type.
Calculator 02 of 05
See what one pip is worth in your account currency for any position size. This is the number behind every stop-loss and take-profit decision.
Pick a pair and a position size to see the pip value.
Calculator 03 of 05
Check how much of your equity a position will lock up as margin before you open it — the number that decides whether you still have room to survive a drawdown.
Choose a pair, a position size and a leverage to see the margin requirement.
Calculator 04 of 05
Turn a price move into money. Enter entry, exit and position size to see the result in pips and in your account currency — useful before a trade as much as after one.
Enter the position size, entry price and exit price to see the profit or loss.
Calculator 05 of 05
Convert any amount between 24 currencies — majors, minors and metals — at the mid-market rate. Everything happens in your browser, with no signup and no tracking.
Mid-market rate - your bank or broker will add a spread or a commission.
Your inputs are remembered in this browser only — nothing is uploaded and no account is needed. Rates come from public mid-market feeds (open.er-api.com for currencies, gold-api.com for gold and silver). If that feed is unreachable the page falls back to the last rates this browser saw, then to a bundled offline table, so all five calculators keep working with a manual rate.
A pip ("percentage in point") is the smallest standard price move in a currency pair. For most pairs, one pip equals a change in the fourth decimal place (0.0001). Pairs that include the Japanese yen are the exception — since the yen is quoted with fewer decimal places, one pip there equals a move in the second decimal place (0.01).
Pips exist so traders have a common unit to describe price movement and profit or loss, regardless of which currency pair they are trading. Saying "the trade moved 35 pips" means the same thing structurally whether you are trading EUR/USD or USD/JPY, even though the actual price change looks different in each case.
The dollar (or account-currency) value of one pip depends on three things: the currency pair, the size of your position, and the current exchange rate. That is exactly what the Pip Value Calculator above works out for you automatically.
Gold and silver sit outside the standard four-decimal convention. This page follows the usual retail convention for metals — they are quoted to two decimals, so on XAU/USD one pip equals one point (0.01). Every calculator on this page states the pip size it is using, so you can always see the assumption behind the number.
Position sizing answers one question: how many units of currency should you buy or sell so that if your stop-loss is hit, you lose no more than the amount you are willing to risk?
The calculation depends on three inputs: your account balance, the percentage (or fixed amount) of that balance you are willing to risk on the trade, and the distance in pips between your entry price and your stop-loss.
A trader risking 1% of a $10,000 account with a 20-pip stop-loss needs a much larger position to hit that same 1% risk than a trader using a 100-pip stop. Wider stops call for smaller position sizes, and tighter stops allow for larger ones — the Position Size Calculator does this math instantly so you never have to estimate it under pressure.
Getting this step wrong is one of the most common ways new traders damage their accounts — not by picking bad trades, but by sizing good trades too large relative to their risk tolerance.
Margin is the amount of money your broker sets aside from your account balance to open and hold a leveraged position — it isn't a fee, it's collateral that gets released back to you when the position closes.
Required margin depends on the size of the position and the leverage your broker offers. At 1:100 leverage, a $100,000 position requires $1,000 of margin. At 1:500 leverage, that same position only requires $200. Higher leverage means less margin is tied up per trade, but it also means your account can absorb less adverse price movement before a margin call, so it cuts both ways.
The Margin Calculator above lets you test different leverage levels against a given position size, so you can see exactly how much of your account balance a trade will use before you place it.
Once a trade closes, profit or loss is simply the difference between your entry and exit price, converted into pips, and then multiplied by your pip value and position size.
The Profit/Loss Calculator above lets you test this before you ever place a trade — plug in a hypothetical entry, a target exit, and your position size, and see exactly what the trade is worth in your account currency if it plays out. It's a useful sanity check for whether a setup's potential reward actually justifies the risk you calculated in the Position Size tab.
These five calculators answer the arithmetic questions. The BneuTech Trading OS answers the ones that come next: when to trade, how much to trade, and whether your own behaviour is helping or hurting your results.
