Antigravity credits calculator and lockout planner
Google meters Antigravity in compute quota and sells AI credits for overage, and publishes no numeric quota, no credit-per-token rate, and no pack prices on public pages. This page computes everything the published pages actually support, and labels every community-measured number as the estimate it is. Facts verified against Google's pages on 2026-07-22.
The lockout planner
Two limits stack on paid plans: a five-hour sprint quota and a weekly ceiling. The mechanic is first-party; the units below are community-measured on Pro (about 250 units per five hours, weekly ceiling near 2,800), because Google publishes none.
Weekly ceiling hits
day 4.9
Friday, if your quota week starts Monday
Locked out per week
2.1 days
30% of the week unavailable
Bridging with credit packs
$14.96 to $28.80
313 locked prompts at community-measured per-prompt rates
Community-derived estimate, not a quote: quota units, the heavy-model multiplier (8x), and per-prompt dollar rates are forum-measured and Google has changed limits at least twice since launch. Ultra ceilings combine the community Pro baseline with Google's stated 5X/20X multipliers. The five-hour sprint cap can also bite intraday; the weekly ceiling is the one that locks you out for days.
What a dollar of subscription buys, per tier
Google states quota only relatively: Ultra $100 buys 5X of Pro, Ultra $200 buys 20X. Dividing price by multiple is first-party arithmetic, and it shows the $100 tier carries no quota discount at all:
| Plan | Price | Stated quota | $ per quota unit | Discount vs Pro |
|---|---|---|---|---|
| Free | $0/mo | not stated | - | - |
| Google AI Pro | $20/mo | 1X of Pro | $20.00 | 0% |
| Google AI Ultra ($100) | $100/mo | 5X of Pro | $20.00 | 0% |
| Google AI Ultra ($200) | $200/mo | 20X of Pro | $10.00 | 50% |
The $200 tier also unlocks third-party model access, per the plans page. Full comparison: Pro vs Ultra quota.
Credit packs
Pack sizes are on Google's help pages; pack prices are not. The prices below are press and community reported, implying roughly $1.00 per 100 credits:
| Pack | Reported price | $ per credit | Bulk saving |
|---|---|---|---|
| 2,500 credits | $24.99 | $0.009996 | 0% |
| 5,000 credits | $49.99 | $0.009998 | 0% |
| 20,000 credits | $199.00 | $0.009950 | 0.5% |
The flat structure is the finding: assembling 20,000 credits from 2,500-packs costs $199.92 versus $199.00 for the big pack, a bulk saving of $0.92. Credits are overage-only above plan quota. More: what one Antigravity credit costs.
What Google does not publish
Checked across Google's Antigravity docs, blog, and help pages on 2026-07-22:
- credit-per-token rate
- credit-per-request rate
- per-model credit multipliers
- numeric plan quotas for any tier
- included credit amounts per plan since 2026-05-19
- top-up pack prices on public pages
- credit expiry period
- weekly-lockout duration
- the quota-to-credits exchange rate
Google's own help page confirms that "the amount of AI credits used for each feature and model varies" without quantifying it. Everything above this list is computed from what IS published; everything community-measured is labeled.
FAQ
- How much does one Antigravity credit cost?
- Google does not publish a credit price on any public page. Pack sizes are first-party (2,500, 5,000, or 20,000 credits); the prices reported by press and community sources ($24.99, $49.99, $199) imply roughly one cent per credit. Prices appear only inside the authenticated purchase flow.
- How does the Antigravity weekly lockout work?
- Two limits stack: quota refreshes every five hours until a weekly ceiling is reached; hitting the ceiling locks you out until the weekly reset regardless of five-hour refreshes. The mechanic is documented by Google; the numeric limits are not, and community measurements put the Pro sprint at about 250 units per five hours with a weekly ceiling near 2,800.
- Do Antigravity plans include AI credits?
- No. Since 2026-05-19 plans include compute quota, not credits. Purchased AI credits cover overage above plan quota only, consumed at Gemini Enterprise Agent Platform consumption pricing per Google's docs.
- Is Google AI Ultra worth it for Antigravity quota?
- The $100 Ultra tier carries exactly zero quota discount: $100 buys 5X of Pro quota, the same $20 per quota unit Pro charges. Only the $200 tier prices quota below Pro, at $10 per unit, half the Pro rate, and it adds third-party model access.
