A protective put caps your downside on the CRL position at a chosen floor; a zero-cost collar pays for that floor by capping the upside. This calculator prices both structures off the current CRL option chain, with annual cost, max loss, and tax-treatment notes.
Example: a 5,000-share CRL position at $295.01 is worth $1,475,050. A 1-year 30%-OTM put on that position typically runs 2-4% of position value per year (about $29,501 to $59,002) before any premium offset from a short call. The calculator prices both structures off CRL's current option chain so you see the actual cost for your chosen floor, tenor, and cap.
