Kiro Pro vs Power: 1,000 vs 10,000 Credits, and the Tiers in Between
Kiro Pro is $20 for 1,000 credits, Power is $200 for 10,000. Where Pro+ and Pro Max fit, when $0.04 overage beats upgrading, and who needs Power.

Kiro plans, credits, add-ons and the first-upgrade offer checked on kiro.dev/pricing (prices Nov 1, 2026; plan cards and FAQ re-read Nov 5, 2026). Add-on rules checked Nov 1, 2026 in Kiro’s add-on credits docs. US prices, before tax. Every source is listed at the bottom. No affiliate links on this page (how we work).
Kiro Pro vs Power is $20 for 1,000 credits a month against $200 for 10,000. Here’s the finding that surprised me: you pay exactly the same per credit on both. $20 ÷ 1,000 is 2 cents. $200 ÷ 10,000 is 2 cents. Pro+ and Pro Max land on 2 cents too (our arithmetic on Kiro’s prices). There’s no bulk discount for buying the big plan.
So Power doesn’t buy you cheaper credits. It buys you more of them up front, so you don’t pay the 4-cent add-on rate. Whether that matters depends on one number: how many credits you actually burn in a month.
Kiro Pro vs Power: the short answer
- Under 1,500 credits a month: stay on Pro and buy add-ons when you spill over.
- Steadily above 7,500 a month: Power is the cheapest way to get the credits (our arithmetic below).
- Somewhere in between: you probably want Pro+ ($40) or Pro Max ($100), not Power.
- Anything besides credits: Kiro’s pricing page lists the same two lines on every paid plan, “Access to premium models” and “Add-on credits ($0.04/credit)”. I found no published non-credit difference between Pro and Power.
The ladder
Kiro paid plans, verified on kiro.dev/pricing (prices Nov 1, 2026, re-read Nov 5, 2026). $/credit is our arithmetic.
| Plan | Price | Credits | $/credit | Overage |
|---|---|---|---|---|
| Pro | $20/mo | 1,000 | $0.02 | $0.04 |
| Pro+ | $40/mo | 2,000 | $0.02 | $0.04 |
| Pro Max | $100/mo | 5,000 | $0.02 | $0.04 |
| Power | $200/mo | 10,000 | $0.02 | $0.04 |
Prices are per user per month and “do not include applicable taxes or duties”. Kiro “processes paid subscriptions on the 1st day of each calendar month”, and there’s no annual option on the page. The free tier is $0 for 50 credits. Over a year, that’s $240 for Pro and $2,400 for Power, with no yearly discount (our arithmetic).
What counts as a credit? Kiro says: “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.” Model choice matters too. Kiro’s own example: a task that costs X credits in Auto “will cost you 1.3X credits to execute via Sonnet 4.6.” The full credit rules are in Kiro credits.
Break-even: Pro plus add-ons vs upgrading (our arithmetic)
Add-on credits cost $0.04 each, double the plan rate. That doubling is the whole decision. On Pro, every credit past 1,000 costs 4 cents, so:
| Monthly use | Pro + add-ons | Cheapest option |
|---|---|---|
| 1,000 | $20 | Pro ($20) |
| 1,500 | $40 | Pro or Pro+ ($40) |
| 2,000 | $60 | Pro+ ($40) |
| 3,000 | $100 | Pro+ + add-ons ($80) |
| 3,500 | $120 | Pro+ + add-ons or Pro Max ($100) |
| 5,000 | $180 | Pro Max ($100) |
| 7,500 | $280 | Pro Max + add-ons or Power ($200) |
| 10,000 | $380 | Power ($200) |
The break-even points, each worked as plan price + (credits over the allowance × $0.04):
- Pro vs Pro+: 1,500 credits a month ($20 + 500 × $0.04 = $40)
- Pro vs Pro Max: 3,000 credits ($20 + 2,000 × $0.04 = $100)
- Pro vs Power: 5,500 credits ($20 + 4,500 × $0.04 = $200), though Pro Max is cheaper than both at that level
- Pro+ vs Pro Max: 3,500 credits ($40 + 1,500 × $0.04 = $100)
- Pro Max vs Power: 7,500 credits ($100 + 2,500 × $0.04 = $200)
Two caveats keep this from being a clean chart. Add-ons come in packs: “Packs range from $5 (125 credits) to $100,” so real spending moves in pack-sized steps, not single credits. And add-ons don’t vanish at month end. “Unused add-on credits roll over and expire 12 months from the date of purchase.” Plan credits don’t: “Unused credits do not roll over to the next month.”
That rollover is the underrated part. A Power subscriber who uses 6,000 credits in a quiet month throws away 4,000 credits. A Pro user with add-ons keeps whatever’s left of their packs for a year. It’s Skyler’s storage unit from Breaking Bad: unglamorous, a bit of a pile, but nothing in there disappears on the 1st.
When both plan and add-on credits run out, “Kiro pauses usage until you purchase more add-on credits or your plan resets.” Free can’t buy add-ons. How the monthly cap behaves in practice is in Kiro usage limits.
What else changes besides credits
Short answer: nothing that Kiro publishes. As of Nov 5, 2026, the Pro, Pro+, Pro Max and Power cards each list the same two lines, “Access to premium models” and “Add-on credits ($0.04/credit)”. The FAQ says Kiro Web is “Available to Kiro Pro, Pro+, Pro Max, and Power users”, all four tiers alike. Priority access, faster models, extra support or a different model list for Power: not published.
The first-upgrade offer works on any paid tier. Since Nov 1, 2026: “The first time you upgrade from Kiro Free to Pro, the rest of that month is free, and you get 500 trial credits to use within 12 months.” If you start higher, “the free Pro month still counts, and you pay only the difference between your plan’s prorated price and the prorated Pro price.” It’s the first upgrade only; later upgrades are “prorated as usual, without a free month”. (People who upgraded before Nov 1 keep the old $20 discount.)
Honestly, I’d like Kiro to give the $200 buyer something besides a bigger bucket. Power is ten Pros stapled together at the same per-credit price. That’s fair, and it’s also a little lazy for a plan Kiro clearly wants heavy users on.
Here’s what I’d do
- New to Kiro: start on Pro and use the first-upgrade offer. You get the rest of the month free and 500 trial credits, then you’ll know your real monthly burn before committing to anything bigger.
- Spilling slightly past 1,000: buy add-on packs. Below 1,500 a month, they’re cheaper than Pro+, and they roll over.
- Steadily 1,500 to 3,500: Pro+ at $40. See Kiro Pro vs Pro+ for that step.
- Steadily 3,500 to 7,500: Pro Max at $100, topping up with add-ons in heavy months.
- Steadily above 7,500, every month: Power. Make sure it’s every month, though. Power’s unused credits expire at the reset, and there’s no annual discount to soften a slow month. As Omar put it in The Wire: you come at the king, you best not miss. Buy Power, then use it.
- Switching to Auto when you can: Kiro’s 1.3X Sonnet 4.6 example means model choice moves your burn rate nearly as much as plan choice.
