Short answer: a Kiro credit is Kiro’s unit of agent work, and it costs $0.04 if you buy it on its own, or $0.02 inside any paid plan (our division of Kiro’s prices, verified Nov 1, 2026). Burn rate depends on the model’s multiplier, from 0.05x to 2.2x (verified Oct 27, 2026). From Nov 1, 2026, a first upgrade from Free swaps the old $20 credit for the rest of the month on Pro free plus 500 trial credits.
What Kiro does not publish: any conversion from credits to tokens. If you came here searching “Kiro credits to tokens”, that’s the honest answer, and we’ll explain why below.
This page covers credit mechanics only. For the plan ladder and what each tier includes, see Kiro pricing. Everything below is from Kiro’s own pages.
Quick answer
What are Kiro credits? Kiro’s billing unit for agent work: every prompt, spec task and hook run uses some. How much does a Kiro credit cost? $0.04 each as an add-on, and $0.02 each inside any paid plan, from Pro at $20 for 1,000 credits up to Power at $200 for 10,000 (Kiro pricing, verified Nov 1, 2026).
- Smallest charge: 0.01 credits.
- Multipliers: Opus 5.5 is 2.0x Auto, Sonnet 5.5 1.3x, Haiku 5.5 0.06x up to 100K tokens.
- Reset: plan credits renew each billing cycle; add-on and trial credits last 12 months.
- Free users get 50 credits and can’t buy add-ons.
Credits per plan, and what one credit costs
| Plan | Price | Credits | Overage |
|---|---|---|---|
| Free | $0 | 50 | Not available |
| Pro | $20/mo | 1,000 | $0.04/credit |
| Pro+ | $40/mo | 2,000 | $0.04/credit |
| Pro Max | $100/mo | 5,000 | $0.04/credit |
| Power | $200/mo | 10,000 | $0.04/credit |
Per plan credit, every paid tier works out to $0.02 (price divided by credits, our arithmetic). Add-ons start at $5 for 125 credits.
Prices and credits: kiro.dev/pricing, verified Nov 1, 2026; credit counts re-checked against the tier table in Kiro’s billing docs, Nov 2, 2026. Overage: add-on credits docs, verified Nov 1, 2026. Kiro doesn’t publish a per-credit price for plan credits. Prices are per user per month and exclude tax; no annual price is published.
Two takeaways: bigger plans get no bulk discount per credit (you’re buying volume, not a better rate), and add-on credits cost double the in-plan rate. A Pro user who regularly buys 1,000 extra credits pays $20 + $40 = $60 a month for 2,000 credits. Pro+ gives 2,000 for $40.
What burns a credit
Kiro’s pricing page (verified Oct 20, 2026): “A credit is a unit of work in response to user prompts. Simple prompts can consume less than 1 credit. More complex prompts, such as executing a spec task, typically cost more than 1 credit.” And “Any prompt you ask Kiro to execute, whether in vibe mode or spec mode, as well as spec refinement, task execution, and agent hook execution, will consume credits.” Agent hooks are the one to watch. A hook that fires on every file save is a prompt, and prompts cost credits.
Credits “are consumed fractionally based on each request” (kiro.dev/docs/billing, verified Oct 20, 2026). Kiro doesn’t publish a fixed credit cost for a spec, task or hook.
Model multipliers: the real price list
Every model is priced “relative to Auto (1.0x baseline)” (Kiro models docs, page updated Oct 24, 2026, verified Oct 27). Kiro’s own example: a task costing 10 credits on Auto costs 20 on Opus 5.5, 22 on Opus 5, “0.6 credits at Haiku 5.5’s 0.06x rate for a request up to 100K tokens, or 0.5 credits on Qwen3 Coder Next.”
Paid plans (Pro, Pro+, Pro Max, Power), verified Oct 27, 2026:
| Model | Multiplier |
|---|---|
| GPT-5.6 Sol | 4.4x |
| Kimi K3 | 2.4x |
| Opus 5 / 4.8 / 4.7 / 4.6 / 4.5 | 2.2x |
| GPT-5.6 Terra | 2.2x |
| Claude Opus 5.5 | 2.0x |
| Sonnet 5.5 / 5 / 4.6 / 4.5 / 4.0 | 1.3x |
| Auto | 1.0x |
| GPT-5.6 Luna | 0.6x |
| GLM-5 | 0.5x |
| Claude Haiku 4.5 | 0.4x |
| DeepSeek 3.2, MiniMax M2.5 | 0.25x |
| MiniMax M2.1 | 0.15x |
| Claude Haiku 5.5 | 0.06x (0.3x over 100K) |
| Qwen3 Coder Next | 0.05x |
Notes from the same docs: Claude Fable 5.1 (6x) is Enterprise only. GPT-5.6 requests over 272K tokens were billed at double (Sol 8.8x, Terra 4.4x, Luna 1.2x) when we last read that line on Oct 20, 2026. Model selection is “only available for chat experience”.
Free plan models: Auto, Claude Sonnet 4.5 and Sonnet 4.0 (1.3x), DeepSeek 3.2 and MiniMax M2.5 (0.25x), GLM-5 (0.5x), MiniMax M2.1 (0.15x), Qwen3 Coder Next (0.05x) (models docs, verified Oct 27, 2026; multipliers Oct 20). On Free, 50 credits on Sonnet 4.5 is the same work as about 38 credits on Auto, by our arithmetic.
The quiet surprise in this table: Opus 5.5, the newest Opus, is cheaper per task than the older Opus 5 and 4.x models (2.0x vs 2.2x). If you pick Opus by habit, pick the new one.
Kiro credits vs tokens
There is no published conversion. Kiro’s billing and models docs (verified Oct 27, 2026) describe credits as fractional units relative to Auto, with no tokens-per-credit figure and no credits-to-dollars figure beyond the $0.04 add-on price.
Tokens still matter, though, in two places Kiro does document:
- Haiku 5.5 costs 0.06x up to 100K tokens per request and 0.3x above that. A long-context request on Haiku 5.5 costs five times more per task.
- GPT-5.6 requests over 272K tokens were billed at double (Oct 20, 2026 reading).
So the only fair comparison with token-billed tools is plan to plan, as in Kiro Pro vs Claude Pro.
“Kiro credits to tokens” is one of Google’s top suggestions when you type “kiro credits”, and Kiro’s answer is a multiplier table relative to a model called Auto, whose own cost per token isn’t published. It’s a currency pegged to another currency nobody can see. Meter to 0.01 credits by all means, but give buyers one anchor.
Resets, rollover, add-ons and tracking
When do Kiro credits reset?
At the start of your next billing cycle (the 1st of the month on paid plans). Kiro’s billing docs: “For all tiers, your plan credits renew at the beginning of the next billing cycle. Trial credits don’t reset at the end of the month” (kiro.dev/docs/billing, verified Nov 2, 2026). Kiro “processes paid subscriptions on the 1st day of each calendar month”, and “Unused credits do not roll over” (pricing, verified Nov 1, 2026).
Add-ons (add-on credits docs, verified Nov 1, 2026):
- Paid plans only, $0.04 per credit, $5 (125 credits) to $100 per pack, up to five packs.
- Used after plan credits; they roll over and expire 12 months after purchase.
- Run out of both and Kiro “pauses usage until you purchase more add-on credits or your plan resets”. Seeing an error instead of a pause? See Kiro “Error sending prompt” or, if Kiro won’t even start, Kiro error code 21.
- Kiro sends a usage notification at 80% of your monthly credits (usage notifications docs, verified Nov 1, 2026).
Free users can’t buy add-ons. Kiro’s billing tier table lists Free with 50 credits and add-ons “Not available” (kiro.dev/docs/billing, verified Nov 2, 2026).
The first-upgrade offer changed on Nov 1, 2026
Kiro’s billing docs, verified Nov 2, 2026: “Starting November 1, 2026, your first upgrade from the Kiro Free tier comes with a free trial: the rest of that month on Pro is free, and you get 500 trial credits on any paid plan (Pro, Pro+, Pro Max, or Power).” This replaced the old $20 credit. Kiro’s pricing page says upgrades made before Nov 1 keep the $20 discount (verified Nov 1, 2026).
How it works, per the same docs:
- Fees and plan credits are prorated to the second; first upgrade only.
- Trial credits are used after plan credits and expire after 12 months.
- Back on Free, unused trial credits only work on Free-tier models.
Kiro’s worked example, upgrading on day 15 of a 30-day month:
| Plan | You pay | Plan credits | Trial credits |
|---|---|---|---|
| Pro | $0 | 533 | 500 |
| Pro+ | $10.67 | 1,067 | 500 |
| Pro Max | $42.67 | 2,667 | 500 |
| Power | $96.00 | 5,333 | 500 |
Source: kiro.dev/docs/billing, verified Nov 2, 2026.
Better than $20 off? At the $0.04 add-on rate, 500 credits are worth $20 (our arithmetic), and Pro upgraders also skip the rest-of-month fee. The catch: they’re credits, not cash, and they expire in a year.
Students on Kiro’s student offer get “1,000 credits per month free for one year” (kiro.dev/students, verified Nov 1, 2026). As of Oct 22, 2026 the same page said “Credits do not roll over month to month, and add-on credits are not available”.
Tracking: your subscription dashboard is “updated at least every 5 minutes” (Kiro FAQ, verified Oct 26, 2026). Five minutes is fine for budgeting, less fine if a busy hook is chewing through credits as you read the dashboard.
Here’s what I’d do
Set Auto as default. It’s the 1.0x baseline, and everything Kiro prices is relative to it.
Use Haiku 5.5 for short, simple chats. At 0.06x it’s the cheapest Claude in Kiro, as long as the request stays under 100K tokens.
If you need Opus, use Opus 5.5. It’s 2.0x against 2.2x for the older ones.
Audit your hooks. Every hook run is a prompt that consumes credits.
Buying add-ons every month? Move up a plan instead. Same $0.02 rate, no $0.04 overflow. See Kiro pricing, Is Kiro free?, Kiro vs Cursor, Codex credits and AI coding tools compared.
Running out of credits every month? Kiro Pro vs Pro+ shows when the bigger plan beats buying add-on credits.
For the plan-by-plan caps and reset dates in one place, see Kiro usage limits.
Wondering whether Power’s 10,000 credits beat buying add-ons? Kiro Pro vs Power runs the per-credit math.
