◈   AI Workflow Cost CheckFREE DECISION CHECK

FOR ZAPIER USERS

Will your own AI key
actually lower your bill?

Fewer tasks can still cost more. Compare bundled AI with your own OpenAI key on the same Zapier plan, before you change anything.

Your monthly workflow

Use a typical month. All steps below happen after the filter.

Adjust AI usage & plan assumptions

Your own key uses standard GPT-4.1: $2 / million input tokens and $8 / million output tokens. This check uses GPT-4.1 in both configurations; prompts and outputs can still differ. Replace these assumptions with actual usage before deciding.

YOUR SAME-PLAN COMPARISON

Checking your example…

Bundled AI

Platform subscription; AI included

Your own AI key

Expected usage, not a bill or a guaranteed saving. Taxes, currency changes, retries, other paid services and any tasks before the filter are excluded.

What this check can tell you

Less usage ≠ a cheaper subscription

Each successful AI step consumes (1 + successful tool calls) × 3 tasks with Advanced, or × 1 with your own key. Ordinary successful actions count separately. If both options fit in the same paid allowance, the platform bill stays the same. Your own key adds a separate AI bill. If either exceeds 750 tasks, this check stops quoting its total.

Make & n8n need a separate check

They use different billing units and workflow rules. This check does not price either platform or recommend migration. Compare the actual workflow, features and current plan separately.

How accurate are the token costs?

Tokens vary by request. Enter averages per model call from representative runs. The estimate covers standard GPT-4.1 text usage only; it excludes cached-input discounts and other API tools.
