How it works
- How is credits value calculated?
- Credits used = min(included credits, monthly PAYG). Net with sub = subscription + max(0, PAYG − credits). PAYG alone = monthly PAYG. Savings = PAYG alone − net with sub (can be negative).
- Why are credit defaults $100–$500?
- They are editable news-range estimates (~2026-10), not an official SKU table. Late-October 2026 reports also said some grandfathered Pro allotments were roughly halved from ~2026-10-30 at the same $200 price, sometimes with one-time credits—confirm on your account page and edit the fields.
- Does this include ChatGPT Plus?
- Presets focus on Pro/Business + API credits. For Plus/Go/Pro subscription list totals without credits, use the ChatGPT Plus cost calculator.
- What if PAYG is below included credits?
- Unused credits are shown; net with sub equals the subscription fee alone for that month in this model.
- Are these figures billing-grade?
- No. Strong emphasis on estimates only; official OpenAI checkout and invoices prevail.
