How to Calculate Lot Value in Gold

A hundred ounces

On most platforms one lot of gold is a hundred ounces, and the price is dollars per ounce, quoted to two decimals. At the open of 3 September 2026, 4,391.14 an ounce, one lot was $439,114 of gold, and at a leverage of one to a hundred — the broker holding back one hundredth and lending the rest — $4,391 of that was held back. The steps follow from the hundred: a one-cent move in the price, the last digit, is a dollar on the lot; a ten-cent move, which most brokers call a pip, is ten dollars; and a one-dollar move is a hundred dollars. That last one is the number to carry, because gold moves in dollars.

One real day, three sizes

Here is the lot value on a real day. Gold opened on 3 September 2026 at 4,391.14 and closed at 4,472.90, a move of $81.76 an ounce. On a full lot, a hundred ounces, that day was $8,176. On a tenth of a lot, ten ounces, it was $817.60. On the smallest size most brokers allow, a hundredth of a lot, one ounce, it was $81.76. The move per ounce is the day and the ounces are the size; multiply the two and the size becomes money.
