Get Kiro Pro+ for about $0 in your first month with the $20 new-user credit
Your first paid Kiro upgrade comes with a $20 credit, and plans are prorated by the days left in the month. Start the $40 Pro+ plan in the second half of the month and the first month is about $0 before tax, with users reporting around 2,000 credits. Your card may see a temporary $20 hold, and remember to cancel before the 1st.
The briefing
The first time you upgrade to a paid Kiro plan, you get a $20 credit toward your subscription. Kiro bills every plan on the 1st of each month, and if you start mid-month you only pay for the days left. Put those two rules together and the later in the month you sign up, the less your first month costs. Start Pro+ in the second half of the month and it can come out to about $0 until the month ends.
What you get
Kiro Pro+ lists at $40 a month and gives you premium models such as Claude Opus 5, Claude Sonnet 5, and GPT-5.6 in Kiro IDE, Kiro CLI, and Kiro Web. Users on linux.do report about 2,000 credits after upgrading to Pro+.
The $20 credit only applies to your first paid upgrade, and you need to sign in with a social login or AWS Builder ID. Enterprise accounts using AWS Identity Center don't qualify.
What it costs
The fewer days left in the month, the less Pro+ costs for that month. With half the month left, the prorated fee is about $20, which the $20 credit cancels out. One user who upgraded on October 16 saw $0 before tax at checkout. The same math works for other tiers. Users estimate Pro Max comes close to $0 with about 6 days left, and Power with about 3 days left.
Kiro's prices don't include tax. Tax is calculated from your billing address, and some regions charge none while others add a dollar or two, so your actual cost will vary.
Users report a hold of around $20 on their card at checkout. Keep that much on the card, since a zero-balance card may be declined.
How to sign up
- Sign in to Kiro with a social login or AWS Builder ID and choose Pro+ on the subscription page.
- Add a credit card, check the amount at checkout, and pay. Visa, Mastercard, and UnionPay all work.
- Your credits arrive right away and last until the end of the month.
On the 1st of next month Kiro charges the full $40 for Pro+. If you only want this one month, cancel renewal on the subscription page after paying so you aren't charged on the 1st.
