The last time I had tried it (circa 2019 I believe) it was around $1.25 per day. It was small enough of a fee to go unnoticed for business travel, and for leisure travel I always thought it was a negligible extra expense. Then, one day a coworker who was an exceptionally frequent traveler (on the road nearly 80% of the time) insisted that I was getting ripped off on valuation and should be getting Hertz rewards points instead. I blindly listened to the advice without so much as really researching it at all, which is ironic considering the lengths I dig to find good value in airline and hotel programs
