Gold position size calculator
Risk a fixed amount and get the exact XAUUSD lot size — so a single gold move never blows up your account.
Position Size & Risk
Enter a stop loss to size the trade. Entry pre-fills from the live gold price. 1 lot = 100 oz; 1 pip (0.01) = $1 per lot.
How it works
Decide how much you are willing to lose if price hits your stop — not how much margin you have. The calculator divides that risk by the loss one lot would take over your stop distance.
Because one standard lot of gold is 100 oz, every $0.01 the price moves is $1 per lot. A wider stop means a smaller lot for the same rupee risk.

Size every gold trade to a fixed risk
The fastest way to lose an account on XAUUSD is to pick a lot size that “feels right” and hope the stop holds. Gold moves fast — a quiet $10 swing on one standard lot is $1,000 — so the professional habit is to fix the risk first and let it decide the size.
Say you fund an account with ₹1,00,000 and risk 1% (₹1,000) per trade. You go short with a stop 100 pips away. On a standard lot a 100-pip move is $100, far more than your rupee risk allows, so the calculator scales you down to roughly 0.11 lots — where a 100-pip stop costs about ₹968. Keep the risk constant and your worst trade is survivable, every time.
Once you know the size, check the margin it ties up and the exact pip value so there are no surprises after you click buy.
Why fixed-risk sizing beats guessing
Most Indian traders start with a number of lots in mind. That is backwards. The market does not care how many lots you want to trade. What matters is how many rupees you can afford to lose if the trade goes wrong.
Fixed-risk sizing means you decide your rupee loss first. You pick a percentage of your account, usually 1% to 2%, and every trade is sized so a stop-out costs exactly that amount. A ₹1,000 risk on a ₹1,00,000 account is 1%. A ₹2,000 risk is 2%.
This removes emotion. You stop asking "how much can I make?" and start asking "how much am I willing to lose?" The answer to that question then dictates your lot size. Not a tip. Not a signal. Not a gut feeling.
Guessing leads to random outcomes. One trade loses ₹3,000. The next loses ₹9,000. Your account bleeds unevenly. Fixed-risk sizing makes losses predictable. That predictability is what keeps you in the game long enough to catch a winning streak.
A worked example in rupees
Take an account of ₹1,00,000. You decide to risk 1%, which is ₹1,000. At an exchange rate of 88, that is roughly $11.36.
You spot a short setup on XAUUSD. Your stop is 100 pips away, which equals a $1.00 price move. On a standard lot, 100 pips equals a $100 loss. That is far too much risk.
So you size down. Divide your $11.36 risk by the $100 loss per standard lot. You get 0.1136 lots. Round it to 0.11 lots. Now a 100-pip stop on 0.11 lots loses about $11, which is roughly ₹968. Close enough to your ₹1,000 target.
The formula is simple: lot size equals rupee risk divided by rupee value of the stop distance. You never start with lots. You always start with rupees.
When your stop is wider or tighter
Stop distance changes everything. If your stop is wider, you must trade smaller. If it is tighter, you can trade larger. The risk stays the same either way.
Imagine the same ₹1,000 risk on the same account. Now your stop is 200 pips, a $2.00 move. A standard lot would lose $200. Your $11.36 risk divided by $200 gives 0.0568 lots. You trade about 0.05 or 0.06 lots.
Now flip it. Your stop is only 50 pips, a $0.50 move. A standard lot loses $50. Your $11.36 risk divided by $50 gives 0.227 lots. You can trade about 0.22 or 0.23 lots.
Notice the pattern. Double the stop, halve the size. Halve the stop, double the size. The rupee risk never changes. Only the lot size adapts. That is the entire discipline in one sentence.
Position sizing mistakes Indian traders make on gold
The biggest mistake is trading a standard lot on a small account. A $10 move on one standard lot is $1,000, roughly ₹88,000. On a ₹1,00,000 account, that is 88% of your capital gone in a single swing. Gold moves $10 in a normal session. You are one bad day away from ruin.
Another mistake is moving the stop after entry. You enter with a 100-pip stop, price goes against you, and you widen it to 200 pips. Your risk just doubled, but your lot size did not change. You are now risking 2% instead of 1%. That is not discipline. That is hoping.
Forgetting the USD to INR conversion is also common. A $20 loss sounds small. It is ₹1,760. A $50 loss is ₹4,400. Always convert. Always think in rupees. Your rent is in rupees. Your food is in rupees. Your trading risk should be too.
Finally, many traders ignore the spread. A $0.30 spread on gold is $30 per standard lot. On 0.10 lots it is $3. On 0.01 lots it is $0.30. That cost comes out of your pocket before the trade has moved a single pip in your favour.
Common questions
How do I size a gold trade to a fixed risk?
Enter your balance, the percentage you will risk, your entry and your stop loss. The calculator returns the lot size where a stop-out loses exactly that amount, because one $0.01 gold move is $1 per standard lot (100 oz).
What lot size should a beginner use on gold?
Most Indian beginners should start at 0.01 or 0.10 lots. On a standard lot a $10 move against you is about ₹88,000, which few retail accounts can absorb. Let a fixed-risk position size, not your margin, decide the lot.
Does the position size change with leverage?
No. Your position size comes from your risk and stop distance. Leverage only changes the margin required to hold that position, not how much you lose if the stop is hit.
Why is my stop distance shown in pips?
One pip on gold is a 0.01 move in price. A stop 20.00 away from entry is 2,000 pips. Showing pips makes it easy to compare risk across setups and to read the pip value.
How do I calculate gold lot size from rupee risk?
First convert your rupee risk to dollars by dividing by the USD to INR rate. For example, ₹1,000 at 88 is about $11.36. Then calculate the dollar value of your stop distance. If your stop is 100 pips, that is $100 per standard lot. Divide your dollar risk by the dollar loss per standard lot. $11.36 divided by $100 equals 0.1136 lots, so you would trade about 0.11 lots. This keeps your rupee loss roughly constant regardless of the trade.
What does 1 lot of gold mean in dollars?
One standard lot of XAUUSD equals 100 troy ounces of gold. The notional value is 100 multiplied by the current gold price in dollars. If gold is at $2,000 per ounce, one lot is worth $200,000. A one dollar price move on a standard lot changes your profit or loss by $100. That is 100 pips at $1 per pip. A 0.10 lot is 10 ounces, and a 0.01 lot is 1 ounce.
How much is a gold spread in pips?
Gold spreads are quoted in dollars and cents of price. A $0.30 spread means the difference between the bid and ask price is 30 cents. Since one pip in gold is a $0.01 price move, a $0.30 spread equals 30 pips. On a standard lot, 30 pips costs $30. On a 0.10 lot it is $3, and on a 0.01 lot it is $0.30. The spread is a real cost, not a rounding error.
Can I trade gold with a ₹10,000 account in India?
You can, but you must trade very small sizes. With ₹10,000, a 1% risk is only ₹100, which is about $1.14 at an exchange rate of 88. If your stop is 100 pips away, that equals a $100 loss per standard lot. You would need to trade 0.011 lots, roughly 0.01 lots. Even a 50-pip stop allows only about 0.02 lots. Most brokers offer 0.01 lots as the minimum, so your risk per trade will be slightly above or below 1%.
