Nine calculators for gold and forex traders. Each one shows its formula, runs in your browser, and sends nothing anywhere. No sign-up required.
Get the lot size, pip value, and margin right before you open a position.
Find the value of one pip for XAU/USD and major pairs, in USD and THB.
Use it before you set a stop loss or take profit, so you know how many pips equal how many dollars.
Example 1 lot XAU/USD = $1.00/pip
Open toolWork out the right lot size from your account balance and the risk you accept per trade.
Use it every time before you place a trade, to keep your risk per trade within your plan.
Example $1,000 account, 2% risk, SL $2.00 = 0.10 lot
Open toolFind the margin your broker sets aside for a position, from lot size, price, and leverage.
Use it before you open a position, to see how much of your balance it locks up as margin.
Example 0.10 lot XAU/USD @ $2,400, 1:500 = $48.00
Open toolTurn a price move into a dollar result, and see the leverage or Thai gold price behind it.
See what a trade makes or loses between its open and close price, in USD and THB.
Use it after a trade closes, or to test a plan before you open one.
Example Buy 0.10 lot XAU/USD, $2,400 → $2,412.50 = +$125.00
Open toolWork out the leverage a position actually uses, from its notional value and your account balance.
Use it to see how aggressive a position really is, whatever leverage your broker offers.
Example 0.5 lot XAU/USD @ $2,400 on $2,000 = 1:60
Open toolConvert the world spot price into the Thai gold-bar price per baht-weight, and back.
Use it when you want to know where the Thai gold price should land after the world price moves.
Example spot $2,400 @ 32.66 = 37,072 THB
Open toolSee what a string of losses or gains does to a balance over many trades.
See how a string of consecutive losses shrinks an account, trade by trade.
Use it to see why a big loss needs an even bigger gain to recover from.
Example 10 losses at 2% each = 18.29% drawdown
Open toolEstimate the odds that a run of trades drags your account down to a loss level you set.
Use it to compare position-sizing choices before you commit to one.
Example 45% win rate, 1.5 R:R, 2% risk, 100 trades = 12.13%
Open toolProject how an account grows when each period's gain is reinvested.
Use it to see the difference reinvesting profit makes over many periods.
Example $1,000 at 5% for 12 periods = $1,795.86
Open toolSize a trade, check it fits your account, then see how it holds up over a long run of trades.
Enter your account balance and the risk percentage you're willing to take, and it works out the right lot size instantly.
Open the Lot Size CalculatorSee how much of your balance that lot size locks up as margin, and how much stays free.
Open the Margin CalculatorRun the same risk per trade through a simulation of many trades, and see the odds it wipes out your account.
Open the Risk of Ruin CalculatorCaution
These numbers come from standard formulas. Individual brokers may define contract size or pip units differently, so always check them against your own account's specs.
No. Every calculation runs on JavaScript in your browser only, and nothing is sent to any server. Close the page and whatever you entered is gone immediately.
Very close, but not always exact, because brokers can define contract size, pip units, or fees slightly differently. Treat these numbers as an estimate, and check them against your actual account specs before every trade.
No. Every tool works immediately, with no sign-up or login required.
No formula can tell you whether one specific trading plan will survive, because trade outcomes are random. The calculator runs thousands of simulated sequences using your win rate and risk settings, and counts how many of them hit your loss level. That share is the probability, a way to compare plans against each other, not a forecast of what will happen to your account.
Where the pip value and lot size formulas for gold come from, how they differ from EUR/USD, and why gold's contract size matters.
