The binomial options pricing model is an option pricing approach used to price American-style options. An American option is a financial contract that can be exercised at any time up to and including on the expiration date. This contrasts with a European option, which can only be exercised on the expiration date.
The binomial model assumes that:
- There is a known constant interest rate (r) over the life of the option
- Volatility is constant over the life of the option.
The binomial model consists of a recursive method in which the value of an option at time “t” is computed from the value of the option at time “t-1”. Note that the binomial method is path-independent.
The binomial model was implemented in the calculator below.
