08/02/2025, 3:21 PMTo calculate API costs for a call in LiveKit, follow these steps:
1. Gather Required Information: Determine session duration, average bitrate, number of participants, and your LiveKit Cloud plan details.
2. Estimate Bandwidth Costs:
◦ Convert bitrate to bytes per second and calculate bandwidth in gigabytes (GB).
◦ Multiply by the number of participants and the cost per GB.
1. Estimate Connection Minutes Costs:
◦ Calculate billable participants and multiply by session duration and cost per minute.
1. Estimate Transcoding Costs (if applicable):
◦ Calculate transcoding minutes based on room or participant usage and multiply by the cost per minute.
1. Estimate SIP Costs (if applicable):
◦ Determine SIP participants and calculate SIP minutes cost.
1. Calculate Total Cost: Add up bandwidth, connection minutes, transcoding, and SIP costs.
For example, a 60-minute session with 100 participants and a 500,000 bps bitrate would result in approximately 21.09 GB of bandwidth, costing $2.53 at $0.12/GB. Adjust calculations based on your specific session details.

08/02/2025, 3:25 PMWhen it comes to figuring out API costs for agents like GPT-4 and ElevenLabs in LiveKit, it’s helpful to look at both LiveKit’s usage-based pricing and the specific pricing details for these third-party APIs. Let’s break it down:
1. LiveKit Costs:
◦ Connection Minutes: You’ll be charged per participant minute.
◦ Bandwidth Usage: Costs are based on outbound data per GB.
◦ Transcoding Minutes: There are charges for both ingress and egress transcoding.
◦ Take a peek at LiveKit’s pricing guide to get a good estimate of these costs.
1. GPT-4 API Costs:
◦ Check out OpenAI’s pricing for the specific GPT-4 model you’re using (for example, $0.002 per 1,000 tokens for GPT-4-turbo).
◦ Calculate how many tokens you’re using based on your input and output text.
◦ Then, multiply that token count by the cost per 1,000 tokens.
1. ElevenLabs API Costs:
◦ Charges depend on the number of characters for text-to-speech synthesis.
◦ Costs might vary depending on the voice model and how long your session lasts.
◦ Be sure to check ElevenLabs’ pricing for the exact rates.
To keep your costs in check, it’s a good idea to use LiveKit’s monitoring tools and keep an eye on your usage metrics from OpenAI and ElevenLabs. For the most accurate calculations, here are the pricing pages to check out:
