Solve for the European put that matches a call via continuous-rate put-call parity (no dividend).
| Put | – |
Use this put-call parity calculator to check a quoted call against the synthetic put, or to price a put from a call. It is European-style, continuous compounding, and assumes no dividend on the stock. American early exercise is ignored.
Put = call + K × e^(−r × T) − S. Type 5 for a 5% continuous rate and 1 for one year to expiry. Spot, strike, and call must be in the same currency.
Spot (S): Current underlying price.
Strike (K): Option strike.
Years (T): Time to expiry in years, e.g. 0.5 for six months.
Rate (%): Continuously compounded risk-free rate as a percent.
Call: Quoted European call price.
Put: Implied European put from parity.
