Last reviewed September 14, 2026

Kindle Unlimited renews monthly on your Amazon account. It can sit on a different card than Prime. You keep every card you carry — this just makes sure Kindle Unlimited renews on the one that earns the most.

Where to update it

In your Kindle Unlimited account: Amazon → Kindle Unlimited Central → Payment settings.

Step by step

Sign in at amazon.com and open Kindle Unlimited Central.
Choose Edit payment method.
Select the card Pikt names for this bill, or add it.
Save. The change applies on your next renewal.

Make your recurring payments count.

Create your Pikt account to personalize recommendations to the cards you carry and the reward preferences you set. In Subscriptions, compare those cards for recurring bills before you change a card on file. Pikt Checkout brings the same estimate to online checkout and names the card likely to earn the most. You choose the card and pay with your own card. No credit card required to sign up for beta.
