The standard BSM formula is for European options, not American. If anyone wants to dive deep into a lot of the different models out there, check out The Complete Guide to Option Pricing Formulas by Espen Haug(1). His site has some wonderful material too(2). I especially like his ‘Exotic Option Fantasy Land’(3) —— (1) https://www.amazon.com/Complete-Guide-Option-Pricing-Formula...

Thanks for the interesting link to Espen Haug!

For non-financial engineers, there is a subtle difference between the two option flavors. Holders of an American option can exercise their right to buy/sell the underlying asset at any time while European option holders can only exercise at expiration date.
