Spread and swap differ by broker, which changes what a position actually costs you.
Yes. For a stock index like US500, the terms are used interchangeably: one point is a price change of 1, and that is the smallest increment the calculator works in.
How much is one point worth on US500?
One point move on US500 is worth $1.00 per standard lot, $0.10 per mini lot, and $0.01 per micro lot. Confirm the exact figure against your own broker's contract spec, since contract size can vary.
How is the S&P 500 point value calculated?
It comes from the instrument's contract size: one standard lot of US500 represents 1 pts, so each point of price movement is multiplied out to a dollar figure already shown as $1.00. The calculator does this multiplication for you once you enter a lot size and a number of points.
How do I work out S&P 500 position size?
Decide how many dollars a given point move should represent, then divide that by the per-lot point value ($1.00 for a standard lot, $0.10 for a mini, $0.01 for a micro) to find the lot size. The calculator lets you test different lot sizes against a set number of points until the dollar value matches what you're planning for.
What's the difference between standard, mini, and micro lot values on US500?
A standard lot moves $1.00 per point, a mini lot (1 pts divided by ten, in the usual convention) moves $0.10, and a micro lot moves $0.01. Use whichever matches the lot size your broker offers.
Does this calculator predict my profit on a US500 trade?
No. It multiplies a point move you supply by the point value in US dollars, so you can see what that move is worth in cash terms. It does not forecast where the price will go or what you will actually make or lose.
