Go plan monthly usage percentage doesn't reconcile with actual spend or weekly percentage

Description

Description

I’m seeing a mismatch between the OpenCode Go dashboard’s monthly usage percentage and the actual usage/spend shown elsewhere in the console.

• Plan: OpenCode Go ($10/month)
• Subscription age: less than 24 hours
• Actual total spend so far: $5.70

The weekly bar reconciles correctly:

• Weekly usage: 19% of $30
• Arithmetic: 0.19 × $30 = $5.70
• This exactly matches the actual total spend.

The monthly bar does not reconcile:

• Monthly usage: 40% of $60
• Arithmetic: 0.40 × $60 = $24.00
• Actual spend is only $5.70
• Difference: approximately $18.30, or roughly 4.2× the actual spend.

Because the subscription began less than 24 hours ago, the monthly window has barely started. Its used-dollar figure should track very closely to the weekly usage figure at this point, rather than reporting approximately four times as much usage.

Expected vs Actual

Expected

The monthly usage percentage should reconcile with actual usage/spend. For a subscription started less than 24 hours ago, it should be close to the weekly used-dollar amount when the same requests are being counted.

With $5.70 of spend:

• Weekly usage: $5.70 / $30 = 19%
• Monthly usage should be approximately: $5.70 / $60 = 9.5%

Actual

• Weekly usage: 19% of $30 = $5.70 — correct.
• Monthly usage: 40% of $60 = $24.00 — does not match actual spend.

Question

Could you confirm whether this is a dashboard/display calculation issue or an actual monthly quota-tracking issue?

This matters because the monthly usage bar is the primary way to monitor the $60 monthly Go-plan cap, and the current discrepancy makes it difficult to trust remaining quota.

Related context

There have been other reports of usage/dashboard inconsistencies and quota-state mismatches, including #26213, #24473, and #34884.

I am reporting only the observed values and arithmetic above; I am not inferring a root cause.

Plugins

None relevant; this report concerns the OpenCode Go web console.

OpenCode version

1.18.18

Steps to reproduce

1. Subscribe to OpenCode Go.
2. Use approximately $5.70 worth of requests within the first 24 hours.
3. Open the usage dashboard at https://opencode.ai.
4. Compare the weekly and monthly usage bars:
   • Weekly: 19% of $30 = $5.70
   • Monthly: 40% of $60 = $24.00
5. Compare both values with the actual total spend shown in the console.
