GitHub Copilot's Sept 1 Credit Cliff: Enterprise Drops 7,000 to 3,900 per Seat, Business 3,000 to 1,900

GitHub Copilot switched to “subscription + GitHub AI Credits usage billing” on 2026-06-01. Existing Business and Enterprise customers got a transitional boost to ease the move — and that boost expires on 2026-09-01, eight days after this check.

Less widely noticed: the “included credits” on individual plans are actually a two-layer structure, one layer fixed and one that GitHub explicitly documents as variable. Here are the official numbers, plus the arithmetic on exactly how much each seat loses after Sept 1.

(All figures read directly from GitHub’s official pricing page and official documentation on 2026-08-24 — not third-party reporting.)

The urgent part: the Sept 1 credit cliff

GitHub’s documentation states that existing customers automatically receive a higher per-seat allowance during the transition, running through 2026-09-01:

In dollars it lands harder: 1 AI Credit = US$0.01, a fixed conversion rate set in the docs. So each Enterprise seat goes from US$70 of included usage per month back to US$39 — the price does not rise, but the same money buys 44% less work.

Three things that catch people out:

1. Only “existing customers” get the boost. Subscriptions starting after the transition are on standard allowances from day one.
2. Credits are pooled at the billing entity level, not allocated per person. After Sept 1 the whole pool shrinks at once, and whoever runs the heaviest agent workflows will drain everyone’s pool first.
3. Credits do not carry over. Unused credits are forfeited; the pool resets to the full monthly amount at 00:00:00 UTC on the first of each month. Stockpiling August’s boost is not possible.

If you administer an organisation, one thing is worth doing before Sept 1: re-check the “additional usage allowed” setting. The default permits spending past the allowance at published rates, which generates an extra bill; the alternative blocks usage until the next cycle. With the pool dropping by roughly 40%, that default becomes far easier to trip into an unexpected invoice.

The hidden structure on individual plans: base is guaranteed, flex is not

Individual plans have no Sept 1 deadline, but they do have a design worth understanding. GitHub’s docs split the monthly included allowance in two:

• Base credits — “included with your plan subscription each month. These match with your subscription price and they never change.”
• Flex allotment — “an additional monthly amount on top of your base credits,” which the docs explicitly define as the variable part of your included usage.

Line that up against the published numbers and the design becomes obvious:

The pattern: base equals the monthly price exactly (US$10 to 1,000 credits, US$39 to 3,900, US$100 to 10,000), matching the docs’ phrase “match with your subscription price.” The flex on top is what currently makes Pro look like “pay US$10, get US$15.”

Stated plainly: flex is defined by GitHub itself as variable, not a permanent commitment. The stated reason is to adapt to model pricing, new models and efficiency gains — which can move it up or down. So when judging value, the conservative approach is to treat base as the floor and flex as a present-day bonus.

Supporting evidence: GitHub’s 2026-04-27 announcement post listed Pro as including “US$10 in monthly AI Credits,” while today’s (2026-08-24) pricing page and docs show 1,500 credits (US$15). The structure has in fact been adjusted upward since the announcement. The two official pages disagreeing is not an error — they are snapshots from different dates, which is why any citation needs to name the page and the date it was read.

What the extra money buys on Max (US$100)

Max is the new top individual tier, positioned in GitHub’s own words for “sustained, high-volume agent workflows.” Item by item:

On unit cost: Pro+ returns US$1.79 of included usage per US$1 paid; Max returns US$2.00. Max is genuinely more efficient per dollar — but only if you actually consume 20,000 credits. Burn 6,000 credits a month and Pro+ at US$39 beats Max at US$100 outright, because the unused 14,000 credits expire regardless.

The rule is simple: check your actual consumption over the past two months before upgrading, rather than reacting to the headline “US$100 buys US$200” multiple. An allowance that never carries over is pure waste when overbought.

What burns credits and what does not

This determines whether you are a heavy user at all:

• Not billed (unlimited on paid plans): code completions and next edit suggestions. The docs state explicitly that neither is billed in AI Credits.
• Billed: Copilot Chat, Copilot CLI, cloud agent, Spaces, Spark, third-party coding agents, and code review.

So if your usage is “type in the editor and let it autocomplete,” you will barely approach the ceiling — Pro at US$10 is comfortably enough for that profile. What actually drains credits is agent mode and cloud agents, which is the behaviour this billing change is really pricing.

Who should act before Sept 1

• Business / Enterprise admins — within these eight days, confirm two things: current monthly pool consumption, and whether “additional usage allowed” should stay on. After Sept 1, identical usage bills the difference.
• Individual Pro users — no deadline, but knowing that 500 of your 1,500 credits are variable flex means future changes should not come as a surprise.
• Completion-only users — unaffected; completions are not metered.
• Deciding between Pro+ and Max — measure two months of real usage first.

Sources and verification

Cross-checked against three independent official sources:

1. Official pricing page, github.com/features/copilot/plans, read 2026-08-24 — Pro US$10 / US$15 credits, Pro+ US$39 / US$70 credits, Max US$100 / US$200 credits.
2. Official documentation, usage-based billing for individuals and for organizations and enterprises — 1 credit = US$0.01, base/flex definitions and split, the Business/Enterprise boost through 2026-09-01, pooling and no-carryover rules.
3. Official announcement, GitHub Copilot is moving to usage-based billing (2026-04-27) — effective date 2026-06-01, boost period and reversion to standard allowances.
