The average cost of a movie rental depends on whether you use a subscription service like Netflix or Amazon Prime or a per-movie rental service like Redbox or iTunes. Depending on how often you watch movies, you might find a better value using a subscription service.
As of 2015, Netflix costs $8 per month, so if you watch one movie a week, you are paying $2 per movie. Amazon Prime costs $99 a year (or $8.25 per month), so it costs about the same as Netflix. Redbox costs $1.20 per day for DVD rentals and $1.50 per day for Blu-ray. Amazon Instant Video prices without a Prime subscription range from $0.99 to $4.99, averaging $3. iTunes movie rentals range from $3.99 to $20, averaging $11. Most public libraries offer DVD collections, which are an excellent free resource.
