Kiro Pro vs Pro+ (2026): Is the Bigger Plan Worth It?
Kiro Pro vs Pro+: what doubling your monthly bill buys in credits, models and overage, when Pro+ beats buying add-on credits on Pro, and when Pro Max wins.
6 min read
Kiro plan prices checked Oct 22, 2026 on kiro.dev/pricing (seen unchanged Oct 26); add-on credit rules checked Oct 27, 2026 in Kiro’s overages docs; model rates checked Oct 27, 2026 in Kiro’s models docs. Every source is listed at the bottom. No affiliate links on this page (how we work).
Short answer: Pro+ is exactly twice Pro. Same models, same rules, twice the credits. Kiro Pro is $20 a month for 1,000 credits. Kiro Pro+ is $40 a month for 2,000 credits. Both work out to 2 cents per plan credit, and both get the same model list. The only thing your extra $20 buys is 1,000 more credits.
So the question isn’t “which plan is better.” It’s “how many credits do I actually burn a month?” Under 1,500, stay on Pro and top up. Over 1,500, Pro+ is cheaper. That’s the whole decision, and the math is below.
Quick answer (Oct 28, 2026)
- Price: Pro $20/month, Pro+ $40/month, per user. No annual price is published for either.
- Credits: Pro 1,000 a month, Pro+ 2,000. Plan credits reset monthly and don’t roll over.
- Models: identical on both, from Claude Haiku 5.5 at 0.06x to GPT-5.6 Sol at 4.4x.
- Running out: both can buy add-on credits at $0.04 each.
- Break-even: Pro+ beats Pro plus add-ons once you need more than 1,500 credits a month.
The plans side by side
| Plan | Price | Credits | Overage |
|---|---|---|---|
| Pro | $20/mo | 1,000/mo | $0.04/credit |
| Pro+ | $40/mo | 2,000/mo | $0.04/credit |
| Pro Max | $100/mo | 5,000/mo | $0.04/credit |
Per user per month, USD. Prices and credits: Kiro pricing, verified Oct 22, 2026 (seen unchanged Oct 26). Overage: overages docs, verified Oct 27, 2026. Above Pro Max sits Power at $200 for 10,000 credits.
Line them up and every paid tier costs the same 2 cents per plan credit: $20 / 1,000, $40 / 2,000, $100 / 5,000, $200 / 10,000. No volume discount at all. Kiro’s ladder is Hooli selling The Box in bigger sizes: same appliance, more rack space, and Gavin Belson’s signature isn’t even on it.
The full ladder, including Free’s 50 credits, is in Kiro pricing.
The math: Pro + add-ons vs Pro+
Add-on credits are $0.04 each, twice the price of a plan credit. They come in packs from $5 (125 credits) up to $100, with up to 5 packs at a time. Kiro uses your plan credits first, and add-ons last 12 months from purchase and do roll over (overages docs, verified Oct 27, 2026).
Here’s the arithmetic, using only those published numbers:
- The gap between Pro and Pro+ is $20.
- $20 buys 500 add-on credits at $0.04.
- So Pro + $20 of add-ons = 1,500 credits for $40. Pro+ = 2,000 credits for $40.
| You use | Pro + add-ons | Pro+ |
|---|---|---|
| 1,000 | $20 | $40 |
| 1,250 | $30 | $40 |
| 1,500 | $40 | $40 |
| 2,000 | $60 | $40 |
Add-on cost = (credits above 1,000) × $0.04, bought in $5 / 125-credit steps. Our arithmetic on Kiro’s published prices.
Below 1,500 credits, Pro with top-ups is cheaper. At exactly 1,500 it’s a tie. Above that, Pro+ wins, and at 2,000 credits it saves you $20 a month.
One thing tilts it a bit toward Pro: plan credits vanish at month end, add-ons don’t. Kiro’s FAQ says “Unused credits do not roll over to the next month” (Kiro FAQ, verified Oct 26, 2026), while add-ons last 12 months. If your usage swings (a 2,200-credit sprint month, then two quiet ones), Pro plus a few packs can beat paying for 2,000 credits you don’t use. In a kitchen like that, every second counts, but on Pro+ every unused credit just goes in the bin on the 1st. “Yes, Chef” to a plan that throws out the leftovers is a hard sell.

Models on each tier
Same list on Pro and Pro+ (and Pro Max and Power). What changes is how far your bucket goes, so the multipliers matter more than the tier. From Kiro’s models docs (page updated Oct 24, 2026, verified Oct 27):
| Model | Multiplier |
|---|---|
| Claude Opus 5.5 | 2.0x |
| Claude Sonnet 5.5 | 1.3x |
| Claude Haiku 5.5 | 0.06x (0.3x >100K) |
| Claude Haiku 4.5 | 0.4x |
| GPT-5.6 Sol | 4.4x |
| GPT-5.6 Terra | 2.2x |
| GPT-5.6 Luna | 0.6x |
| Kimi K3 | 2.4x |
| Auto | 1.0x |
| Qwen3 Coder Next | 0.05x |
Multipliers are relative to Auto (1.0x). Haiku 5.5 is 0.06x for a request up to 100K tokens and 0.3x above. Older Opus models (5, 4.8, 4.7, 4.6, 4.5) are 2.2x and older Sonnets 1.3x. Claude Fable 5.1 is Enterprise only.
Kiro’s own example: a task that costs 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.”
This is why the tier question is really a model question. If you live on Opus 5.5, Pro’s 1,000 credits do half the work they’d do on Auto. If you route small edits to Haiku 5.5, the same 1,000 credits stretch a long way. Before you double your bill, try changing your default model.
Who should stay, upgrade or skip ahead
Stay on Pro if you use under about 1,500 credits a month, or your usage swings a lot. Top up with $5 packs in heavy months; they don’t expire at month end.
Move to Pro+ if you’re consistently over 1,500 credits, especially near 2,000. At that point every month on Pro plus add-ons is costing you real money.
Skip to Pro Max if you’re regularly buying add-ons on top of Pro+. Pro Max is $100 for 5,000 credits. Pro+ plus add-ons reaches $100 at 3,500 credits (2,000 + 1,500 add-ons), so Pro Max is the cheaper way to get anywhere past 3,500.
Power ($200, 10,000 credits) is for people who’d otherwise be stacking Pro Max with add-ons. Same 2-cent plan credit, just a bigger bucket.
If you’re still choosing between vendors rather than tiers, see Kiro Pro vs Claude Pro, Cursor Pro vs Pro+ for the same question at Cursor, or AI coding tools compared. And if $20 is still too much, Is Kiro free? covers the 50-credit Free tier.
Here’s what I’d do
Start on Pro. Watch the usage dashboard (Kiro says it’s updated “at least every 5 minutes”) for one full month. If you end the month buying more than $20 of add-ons, switch to Pro+. If you end it with credits left over, you already have your answer.
Changing models first is the cheapest upgrade there is. Moving routine work from Auto to Haiku 5.5 can save more credits than Pro+ adds.

FAQ
What’s the difference between Kiro Pro and Pro+? Only credits and price: Pro is $20 for 1,000 credits a month and Pro+ is $40 for 2,000, with the same models and rules.
Is Kiro Pro+ worth it? Yes if you use more than 1,500 credits a month, because below that Pro plus $0.04 add-on credits costs less.
