Credit Math FAQ
How much is an Audible credit worth?+
On the standard US Premium Plus plan you pay $14.95/month for one credit, and one credit buys any audiobook regardless of its sticker price or length. That's why long books are the play — a 40-hour epic works out to about $0.37 per hour, while a 6-hour novella costs you $2.49 per hour for the exact same credit.
What should I spend Audible credits on?+
Long books you'll actually finish. LitRPG is one of the best genres for credit value — series entries regularly run 20 to 40+ hours. Books under roughly 8 hours are usually cheaper to buy outright during sales, so save your credits for the doorstoppers.
Do Audible credits expire?+
Yes — on current US plans, credits expire 12 months after they hit your account, and unused credits vanish if you cancel your membership. If you're sitting on a stack, burn them on the longest books on your wishlist first.
