Cost of ES option

Please answer. i look at option chain of ES and there are prices like 3.00 or 10.00 or 1.75. how much is it in $ if i buy 1 option?

 

multiply by 100... thats it.. contract size.. called the multiplier

 

ES options are multiplied by 50. A 1.00 option is worth 50 dollars.

 

true sorry my bad.. ... so its 50 times the price displayed..

 

thanks
