Kiro Pricing and AWS Kiro Pricing With Kiro Credits and Kiro Cost per Plan

Kiro costs $20 per user per month on Pro, $40 on Pro+, $100 on Pro Max and $200 on Power. Free costs nothing and includes 50 credits a month. Kiro bills paid plans on the 1st of each calendar month, prices exclude sales tax, and the pricing page shows monthly prices only, with no annual discount listed. Self-serve plans cover teams of up to 500 users; larger organizations go to AWS sales.

Here is what those list prices add up to for the team sizes most US engineering managers are budgeting:

The mixed row is how most teams end up. A few developers run long spec tasks and agent hooks all day, and everyone else stays inside 1,000 credits. Because each developer needs their own subscription and credits are not pooled, you size each seat separately rather than buying one large allowance for the team.

New users also get a $20 credit toward their first paid month when they upgrade through social login or AWS Builder ID. Kiro prorates that first month: upgrade to Pro on the 15th of a 30-day month and the first charge is $10, which the $20 credit absorbs.

This is the number most Kiro reviews skip. Divide each plan price by its credits and every paid tier lands on the same figure. Upgrading buys more capacity and nothing else; the per-credit price only changes when you go past the allowance.

Two practical consequences follow. A credit bought as an add-on costs twice a credit inside an allowance, so a developer who runs over every month is paying a 100% premium on the excess. And there is no volume discount on the self-serve tiers: Power at $200 is ten Pro allowances at exactly ten times the price.

Kiro measures every model against Auto, its default router, which costs 1.0 times. Picking a specific model multiplies the credits the same task consumes. The table converts Kiro's published multipliers into dollars, using a task that would cost 10 credits on Auto.

Put differently, a Pro allowance of 1,000 credits is worth 1,000 credits of Auto work, about 500 on Opus 5.5 and about 227 on GPT-5.6 Sol. A developer who sets Opus as the default effectively halves the plan, which is why Kiro itself suggests Pro+, Pro Max or Power for people who mostly use Opus. Reasoning effort matters too: lower effort settings produce shorter responses and use fewer credits. Claude Fable 5.1 is listed at 6x and is rolling out only to Enterprise organizations with model governance turned on.

Because add-on credits cost $0.04 and the next tier's credits cost $0.02, there is a monthly usage level above which the upgrade is cheaper. Kiro's own billing doc makes the switch painless: an upgrade between paid tiers charges the price difference for the whole month, recalculates the month's usage against the higher allowance, and leaves add-on credits you already bought in your balance for later.

Below those lines, add-ons win, and they have one advantage the upgrade lacks: they roll over for 12 months. A developer who spikes to 1,300 credits in a release month and sits at 700 the rest of the year should stay on Pro and buy a $20 pack once. A developer who lands at 1,800 every month should be on Pro+. Downgrades are slower: they take effect the following month and the current month is billed at the higher tier, so do not bounce seats up and down within a month.

Seat prices for the tools US teams most often shortlist next to Kiro, read from each vendor's pricing page between September 25 and October 6, 2026. Each one meters usage differently, so compare the seat and then the overage rule.

On list price Kiro Pro sits with Copilot Business and Claude Team at the bottom of the range and costs half a Cursor Teams seat. The catch is the overage rule. Copilot charges $0.01 per credit past the pool and pools across the whole org, while Kiro credits belong to each developer and every credit over the allowance costs double. A team with a few heavy users is cheaper on Kiro only if those users sit on a bigger tier rather than buying add-ons. Full detail on each rival is on our Cursor pricing, GitHub Copilot Enterprise pricing and Claude Code pricing pages.

The fourth row is the expensive mistake. Leaving heavy users on Pro with overage switched on costs $200 more a month than putting them on Power, for the same work. Read the usage dashboard after the first month and move people between tiers before the second invoice.
