04/21/2025, 5:41 PMTo see the cost of calls, check your dashboard at dashboard.vapi.ai/calls. You’ll find a detailed cost breakdown for each call there, which will show you how the dollars are consumed.

04/21/2025, 7:41 PMIf you are using the API, that will be the most effective way to view costs. It may show as 0 because you still have free minutes on your account, so the cost to you is 0.

04/22/2025, 6:59 AMHey Kyle
Are you saying that I need to wait until all my free minutes are used up before I can access the cost breakdown of a call? I urgently need this information, as we have an analysis to prepare and submit to our customers. Please look into this urgently.

04/22/2025, 4:43 PMHey Sahil, you can estimate your call costs by checking the Vapi dashboard. Just go to the left sidebar and click on call logs. There, you’ll see a breakdown of the exact cost for each call, including per-minute projections for transcription, model, voice, and telephony providers. Keep in mind, the 1,000 free minutes only apply to Vapi’s 0.05 per-minute platform fee. Costs from providers like OpenAI or ElevenLabs will still apply as usual.

04/22/2025, 7:41 PMSince you're on the free trial right now it does not show the call costs. Once you are off that, you will than be able to see exactly what I see in the screenshot.

04/23/2025, 4:04 AMSince you're on the free trial right now it does not show the call costs. Once you are off that, you will than be able to see exactly what I see in the screenshot. As of now, when getting data from your webhook you should see a call cost in there.

04/23/2025, 5:54 AMHonestly, it’s pretty frustrating that I have to wait for my free trial to end just to see call costs. It doesn’t make sense to hide such basic info, and having to reach out multiple times with no clear answer is not a great experience.
Sahil
04/23/2025, 5:59 AMI’ve started summing up the costs by checking the logs, where I see entries like:
Model request cost (attempt #1, $0.0002814, 1876 prompt, 0 completion).
Just to confirm—does this include VAPI’s $0.05 per call charge, or do I need to add that separately on top of the model request cost?

04/23/2025, 3:15 PMIf you're using your free 1000 minutes still than, no, it does not incude Vapi's $0.05 per call charge.

Sahil
04/25/2025, 7:37 AMso approx for a call the total cost will be :
llm calls cost (from logs) + stt ($0.01 / min) + tts ($0.04/min) + vapi base charge ($0.05/min)
Please let me know if this breakdown is accurate or if any components should be added or removed.

04/25/2025, 12:28 PMYes, here's an example of one of my calls. It's exactly 1 minute long.
