The Nibble Ads fee is charged per month started, so a 7-day view still includes the full $399 month unless the promo box is checked.

Arithmetic, not a forecast. It shows what has to happen to cover your costs, not what will happen. OpenAI may spend up to twice the daily budget on a single day, averaging out over seven days.[2]

The formula

The fee is billed in USD. If your ad account bills in another currency, enter the fee converted to that currency so all amounts use one currency. The $399/mo fee covers up to $3k/mo in ad spend; each extra channel is $249/mo. Your store pays its ad spend to OpenAI separately.

Quick answers

How is break-even calculated?

Orders to break even = (ad spend + Nibble Ads fee) ÷ (average order value × margin), rounded up. Ad spend = daily budget × days.

Where do the minimum daily budgets come from?

OpenAI's help center lists a minimum daily budget for each billing currency.[1] The calculator prefills that minimum when you pick a currency.

Is this a forecast?

No. It's arithmetic: it shows how many orders cover your costs, not how many orders ads will bring.
