If a value is missing or does not make sense, the field shows a short message explaining what to fix.

Formulas used

This calculator is built on the following relationships between its quantities. Each one can be solved for any of the values it contains, which is why you can leave any single field empty and have it calculated from the others:

call_option_price + strike_price_present_value = spot_price + put_option_price

strike_price_present_value = strike_price / ((1 + risk_free_rate) ^ years_to_expiry)
