Budget for Overskill beyond the headline plan

Record the checkout offer you can buy

On 18 September 2026, the live pricing page showed Studio at $99 per month with 12,000 credits and Max at $199 with 25,000 recurring monthly credits. Older help material described a different plan lineup. Treat the current checkout and account offer as decisive for a purchase; do not budget from an old search snippet or assume an announced feature is already available.

Reserve room for correction work

A first output can need multiple changes. Estimate a modest evaluation allowance before starting and review consumption after each meaningful milestone. Do not translate an advertised credit balance into a guaranteed number of finished apps. Different requests involve different work, and a failed or imperfect generation may still consume credits. Stop the experiment at the chosen boundary rather than buying more automatically.

Make a separate external-cost column

List domains, email delivery, payment processing, storage overages and any other connected service your design needs. Not every project uses every item. Mark unknown amounts as unknown instead of entering zero. A personal planning sheet can distinguish fixed subscriptions from usage charges and from your own review time. This keeps a cheap-looking prototype from hiding a costly operating model.

Compare useful output per evaluation budget

Define what you want the evaluation to establish: perhaps a single complete request workflow with an export. Track total spend against that outcome, not the number of prompts entered. The homepage calculator divides your own monthly software budget by your expected useful users; it is arithmetic, not a forecast. Update it with measured costs later and keep uncertain future usage clearly labeled.

• Before checkout, write down billing frequency, immediate amount due, renewal amount, included credits and the condition that would stop further spend. Preserve a dated copy for your own records.
