Restart clock
A new weekly schedule.
See what an AI quota reset really adds, and what it takes away.
One week's quota equals 100%. Unused is the remaining balance; Refill in is the time to your original scheduled refill.

100% full. 10% replaced. +90% added.

How much weekly quota is still unused? In this model, a reset replaces it; it does not carry over.

Quota on paper = starting balance + full refills before expiry. Refills replace unused balances; yellow pools are future refills, not a stack of saved quota. Dates are spaced for readability, not to scale. Actual extra use also accounts for your daily demand and unused quota lost at every refill.
Example: 70% of a weekly quota per day. Adjust the daily rate below.

Net gain / loss over 2 days% of one week’s quota · compared with no reset
100% means using one full week’s quota in a single day.
70% / day = 70 weekly units per day.

Previously entered days are restored. This value fills only unentered days. Nothing changes until you confirm.
One week's quota = 100. Demand can exceed 100; blank is unknown, not zero. Each block is evenly spread over 24 hours.
Unused quota is replaced. Your next refill may move, too.

Shaded area: the same 48 hours for all three paths.
Compare each reset against doing nothing, using the same demand and time window. Dots mark quota refills, not completed work. Hollow dots at or after the end of the window do not count toward the result.
Both paths replace the unused balance with 100 units now; they do not add 100 on top. The unused balance is already included in the no-reset path, so it must not be subtracted from the final gain a second time. Restarting replaces the old schedule; keeping the date preserves it. A sooner refill can help, but its value still depends on when you need the quota.
*The keep-date path is a model assumption for the Claude scenario. The Codex paid-reset scenario assumes your first request happens immediately. Check the provider rules.
This calculator compares two explicit mechanisms. It does not claim every Codex or Claude reset follows one permanent rule.
These limited product facts are backed by official documentation. The account, offer and date still matter.
The cards illustrate two reset scenarios at equal weekly capacity. The Codex scenario models a paid instant reset with your first request made immediately; its new weekly period starts with that first request. The Claude scenario assumes an extra reset preserves the old refill date. That assumption is not established for every Claude reset by the regular Max-plan documentation. Check the terms of your account or offer.
“It pulls your normal weekly allowance forward rather than adding a separate usage entitlement.”
OpenAI, Paid weekly Work and Codex rate limit resets
A full banked reset refreshes five-hour and weekly windows and changes the weekly reset date.
Exact anchors, eligibility, scope and expiry must follow the account or offer; this is not a universal 168-hours-from-click rule.
The reset applies immediately, but the new weekly period starts at the first Work or Codex request afterward; the next reset is seven days after that request.
Do not generalize this anchor to every banked, hard or global event.
The regular weekly limit refreshes at an account-assigned time; other usage windows and restrictions also apply.
This regular-cycle description does not establish the behavior of every special Claude reset.

ILLUSTRATION / THE DEFAULT TWO-DAY SPRINT
Suppose your quota is 100 units and only 10 remain. A reset replaces those 10 with a fresh 100: 10 unused units are lost, and the balance rises by 90. But “restored now” and “extra demand served” answer different questions.
| Path | Quota used | Extra use |
|---|---|---|
| No reset | 80 | 0 |
| Restart clock | 100 | +20 |
| Keep date* | 140 | +60 |
Units of one 100-unit weekly quota, compared with no reset. *Keep date is a model assumption.
These answers belong to this 48-hour plan. Change the demand, the original refill time or the observation window, and the outcome can change. In a longer plan, a later refill may align with a new demand peak.
A net total is not the complete value of your work. Deadlines, short-window caps, delayed tasks and model capabilities can all matter. Use this tool to understand the calendar effect, not as a promise about your account.
No. It means extra served demand equal to 20% of one normalized weekly quota. It is not a measure of productivity, quality, task success or relative improvement over the no-reset total.
In the restart mechanism, yes. Moving a near-term refill can reduce the demand served inside the selected window. The calculator keeps that negative result visible.
Enter it in “Unused.” Both modeled resets replace that balance with a fresh 100%; they do not stack a new allowance on top. For example, 80% unused is replaced by 100%, so the immediate balance increase is only 20%. That replacement is already reflected in the net comparison; subtracting the unused balance again would double-count it. If the scheduled refill is due now, the model applies it first, then the reset. Check whether these replacement rules match your account.
A balance may help later, but it is not demand already served during this window. Ending balances are shown separately in the detailed comparison.
No. These are examples or values you enter. This page does not connect to your account, redeem resets or change your plan. When you share, we save the selected inputs and calculated result to create a replay link. Anyone with that link can view it. Otherwise, reloading restores the default example.
Enter the end of your current subscription in local time. We compare from a fixed start until that exact time, excluding refills at or after expiry and prorating demand in the last partial day. No renewal is assumed. Quota on paper counts the starting balance and scheduled full refills; actual extra use also accounts for timing, demand and unused quota lost. Both are measured in units of one weekly quota, not money. Shared links preserve the original timestamps.
Five-hour limits, model-specific restrictions, real task duration, priorities, changing capacity, future promotions and delayed-work queues are outside this model. Each entered day's demand is evenly distributed over its 24-hour block.
The brand cards illustrate reset mechanisms at equal normalized capacity, not capabilities or plan allowances. Codex models a paid reset with immediate first use; Claude models an assumed keep-date reset. Actual reset terms depend on your account or offer.
