XAGUSD Lot Size Calculator
Metals
XAGUSD is a metal — this calculator uses its own real contract size and point value rather than a one-size-fits-all forex formula, since point value and typical price steps vary a lot between instrument types.
How do I calculate lot size for XAGUSD?
Say a trader has a $10,000 account and decides to risk 1% of it on a XAGUSD short (sell) at 60.56, with a stop 91 points away at 61.47.
Rounded to a size a broker will actually accept, that's 1.10 lots — a $100.10 loss if the stop is hit.
Using the same 91-point stop, here's how that scales at two common risk levels on a $10,000 account:
- Conservative (1% risk): $100.00 at risk, 1.10 lots
- Balanced (2% risk): $200.00 at risk, 2.20 lots
These are illustrative figures at a fixed example balance and stop — the calculator above uses live prices and your own real inputs. The percentage-risk model itself follows the position-sizing approach popularized by Van Tharp in Trade Your Way to Financial Freedom, among the most widely cited references for treating position sizing as its own risk-management discipline.
What is a standard, mini, and micro lot on XAGUSD?
At XAGUSD's stored contract size (100 units per lot), a "mini" position (0.1 lots) and "micro" position (0.01 lots) scale the point value down by the same factor — $0.10 and $0.01 per point respectively. Useful for sizing a position precisely rather than rounding to a full lot.
When should I adjust my lot size for XAGUSD?
Consider sizing down around high-impact news events or major session overlaps, when volatility and slippage risk increase — a stop that normally holds can be jumped past entirely in a fast move. That risk is higher for this instrument than for a typically calmer major forex pair.
What drives XAGUSD and how that shapes your lot size
XAG/USD is the price of one troy ounce of silver in US dollars. Silver follows many of the same drivers as gold, plus industrial demand, so it often moves in a similar direction but with larger percentage swings. It trades nearly around the clock on weekdays and is most active with gold around the London open and US data.
The price is far lower than gold, so the same dollar distance is a much larger percentage move, and contract size differs widely between brokers. Stops of 0.50 to 1.50 dollars are common intraday.
Worked example: sizing a XAGUSD buy on a $10,000 account
The figures below are invented for illustration and use a rounded reference price, not a live quote. Assume a $10,000 account risking 1% on one buy trade with a stop 80 points below the entry.
- Risk amount: $10,000 × 1% = $100.00.
- Entry 60.000, stop 59.200: the distance is 0.800 in price, which is 80 points (distance ÷ 0.01).
- Value of one point: 0.01 × 100 = $1.00 per point for 1 lot, already in US dollars.
- Risk per 1.00 lot: 80 × $1.00 = $80.00.
- Lots before rounding: $100.00 ÷ $80.00 = 1.2500.
- Rounded down to the 0.01 lot step: 1.25 lots.
- Check: 1.25 × 80 × $1.00 = $100.00, inside the $100 budget.
If price reaches the stop, the loss is $100.00, about 1% of the account. A target twice as far away, at 61.600 (160 points), would pay 1.25 × 160 × $1.00 = $200.00. If you widen the stop to 160 points, the same $100 budget gives 0.62 lots, because lot size shrinks as the stop widens.
Margin check and effective leverage for this XAGUSD trade
- Position value: 1.25 lot × 100 contract × 60.000 = $7,500.
- Margin at 1:100 (1%): $7,500 × 1% = $75.00.
- Effective leverage: $7,500 ÷ $10,000 = 0.8×.
The leverage ceiling your broker allows did not enter the lot-size calculation at all. The risk amount and the stop distance set the size, and leverage only decides how much margin that size locks up. The XAGUSD margin calculator shows how that requirement changes with your own leverage.
Common XAGUSD sizing mistakes
- Copying a lot size from another instrument. One point on XAGUSD is worth $1.00 per lot here, so a 80 point stop risks $80.00 per lot; a pair or index with a different value per point would risk a different amount for the same count.
- Miscounting the point. The price is far lower than gold, so the same dollar distance is a much larger percentage move, and contract size differs widely between brokers.
- Ignoring the spread. The spread is wider than gold's in percentage terms.
- Rounding up. Adding even one 0.01 lot step (1.26 lots) would risk $100.80, above the $100 you set.
Verify XAGUSD against your broker before trading
This page starts from a contract size of 100 and a value of $1.00 per point per lot, which are reference values. Brokers differ, so open the contract specification for XAGUSD in your platform and confirm the contract size, the minimum and maximum volume, and the lot step before you rely on any lot size. A wrong contract size is the most common reason a calculated size is rejected or risks more than expected. For background on the instrument, see silver as an investment on Wikipedia, and for the leverage concept see leverage in finance.

Conclusion
This math only holds if 100 units per lot and $1.00 per point are actually your own broker's real numbers for XAGUSD — every broker can quote contract specifications slightly differently. Always confirm your own platform's XAGUSD specification (right-click the symbol in Market Watch, then Specification) before trusting a suggested lot size for a real trade. See how lot size is calculated step-by-step for the general method, Wikipedia's entry on contracts for difference for how brokers structure these contracts, and real MT4 order-ticket screenshots at different leverage settings for further reading.
Contract specification
Point value and minimum lot step vary by broker on index/CFD instruments — a mismatch here is a common, avoidable cause of an unexpectedly large loss. Confirm this instrument's contract specification in your platform before sizing a real trade.
Frequently asked questions
Can I risk the same percentage on every instrument?
Yes, the risk percentage itself is a decision about your account and stays consistent — what changes between instruments is point value and typical volatility.
Is lot size the same as position size?
Yes — on this site the two terms are used interchangeably; both mean the number of lots to trade.
Does leverage change the XAGUSD lot size I should trade?
No. Position size comes from your risk amount and your stop distance; leverage only caps how large a position you are allowed to open. In the example above a 1:100 account locks up $75.00 of margin for a $7,500 XAGUSD position, an effective leverage of 0.8×, while the lot size was set entirely by the $100 risk and the 80 point stop.
How many lots of XAGUSD can I trade with $1,000 and 2% risk?
With a $1,000 account risking 2% ($20) and the same 80 point stop, the risk per lot is $80.00, so $20.00 ÷ $80.00 = 0.2500 lots, which rounds down to 0.25 lots.
What stop distance is typical for XAGUSD?
Stops of 0.50 to 1.50 dollars are common intraday. At $1.00 per point per lot, each extra point of stop distance adds that amount of risk for every lot you trade, which is why a wider stop always means a smaller lot size.
