AI Voice Agent Pricing Comparison: Vapi vs Retell vs Bland vs Edesy (2026)

Pricing is the most confusing aspect of choosing an AI voice agent platform. Each vendor structures costs differently -- some bundle everything into a single per-minute rate, others charge separately for the AI platform, LLM usage, speech-to-text, text-to-speech, and telephony. What looks like the cheapest option at first glance can end up being the most expensive once all the hidden costs are factored in.

This guide breaks down the actual, all-in cost of running AI voice agents on four leading platforms: Vapi, Retell AI, Bland AI, and Edesy. We compare costs at three volume tiers (1,000 minutes/month, 10,000 minutes/month, and 50,000 minutes/month) so you can see exactly how pricing scales with your operation.

Pricing Model Overview

Before diving into specific numbers, it is important to understand how each platform structures its pricing. The differences in pricing architecture are as significant as the differences in headline rates.

Vapi: Component-Based Pricing

Vapi charges a platform fee plus the pass-through cost of each component in the voice AI stack. You pay separately for:

• Platform fee: $0.05/min
• LLM cost: Varies by provider (OpenAI GPT-4o: ~$0.01-$0.03/min; Anthropic Claude: ~$0.01-$0.04/min)
• Speech-to-text (STT): ~$0.01/min (Deepgram) to $0.02/min (Whisper)
• Text-to-speech (TTS): ~$0.01/min (PlayHT) to $0.04/min (ElevenLabs)
• Telephony: ~$0.01-$0.02/min (Twilio)
• Phone number: $2/month per number

This transparency is valuable -- you can see exactly what you are paying for. But it also means your total cost depends heavily on which providers you select, and optimizing costs requires understanding the tradeoffs between cheaper and more expensive models.

Retell AI: Platform + Infrastructure Pricing

Retell AI uses a similar component-based approach but with slightly different bundling:

• Platform fee: $0.05/min (includes basic STT)
• LLM cost: Pass-through from your chosen provider
• TTS cost: Included in platform fee for standard voices; premium voices at $0.01-$0.03/min extra
• Telephony: $0.01-$0.015/min (Twilio integration)
• Phone number: $1.50/month per number

Retell bundles STT into the platform fee, which simplifies billing slightly compared to Vapi. Their focus on low latency means they have optimized their infrastructure to reduce round-trip processing time, but this optimization does not come with a price premium.

Bland AI: All-Inclusive Per-Minute Pricing

Bland AI takes the simplest approach: one rate per connected minute that includes everything.

• Standard rate: $0.07/min (includes LLM, STT, TTS, and telephony)
• Enterprise rate: $0.05-$0.06/min (at 50,000+ minutes/month)
• Phone number: $2/month per number
• No separate LLM, STT, or TTS charges

This all-inclusive model makes budgeting straightforward. You know exactly what each call costs before you make it. The tradeoff is less flexibility -- you cannot swap in a different LLM or TTS provider to optimize for quality or cost.

Edesy: Platform Subscription + Usage

Edesy combines a monthly platform subscription with per-minute voice usage:

• Platform subscription: Tiered plans (Starter, Growth, Enterprise) with increasing feature sets
• Voice usage: Per-minute rate that decreases with volume commitments
• Included features: WhatsApp CRM, campaign management, analytics, and integrations are included in the platform fee -- not charged separately
• No hidden LLM or TTS surcharges: AI model costs are bundled into the per-minute voice rate

Cost Breakdown by Component

To make a fair comparison, we need to calculate the fully loaded cost per minute for a standard outbound calling configuration on each platform. We will use the following baseline configuration:

• LLM: Mid-tier model (GPT-4o or equivalent)
• STT: Standard accuracy (Deepgram Nova)
• TTS: High-quality voices (ElevenLabs or equivalent)
• Telephony: US domestic calling

Per-Minute Cost Breakdown

Important notes on these numbers:

• Vapi and Retell costs can be reduced by choosing cheaper LLM and TTS providers, but at the expense of conversation quality
• Bland AI's bundled rate uses their own optimized models, which may not match the quality of top-tier third-party models
• Edesy's pricing includes WhatsApp CRM and multi-channel features that the other platforms charge separately for or do not offer

Total Monthly Cost at Different Volumes

1,000 Minutes per Month (Small Business / Startup)

At low volumes, the differences are modest in absolute dollars. Bland AI's all-inclusive pricing is the most predictable. Vapi and Retell require more configuration but offer more flexibility.

10,000 Minutes per Month (Mid-Market / Growing Team)

At 10,000 minutes, the cost differences become meaningful. The $550/month gap between Vapi and Bland AI represents real budget impact. However, if Vapi's flexibility in model selection leads to higher conversion rates, the ROI calculation may still favor it.

50,000 Minutes per Month (Enterprise / High Volume)

*Bland AI enterprise rate of $0.055/min applied at 50,000+ minutes.

At enterprise scale, the gap is dramatic. Bland AI's enterprise pricing is roughly 55% cheaper than Vapi. But enterprise buyers need to evaluate more than per-minute cost -- uptime SLAs, dedicated support, compliance certifications, and conversation quality all factor into the total cost of ownership.

Hidden Costs Most Buyers Miss

1. Development and Integration Time

Vapi and Retell are developer-focused platforms. Building a production-ready voice agent requires:

• 40-80 hours of development time for initial setup
• Ongoing engineering maintenance (10-20 hours/month)
• At a fully loaded developer cost of $75-$150/hour, this adds $3,000-$12,000 to initial setup and $750-$3,000/month in ongoing costs

Bland AI and Edesy offer more turnkey solutions that reduce development overhead significantly.

2. LLM Cost Variability

For Vapi and Retell, LLM costs fluctuate based on:

• Conversation length (longer calls use more tokens)
• Model choice (GPT-4o vs. GPT-3.5 vs. Claude)
• Function calling frequency (each tool call adds tokens)

A 3-minute outbound call might use $0.02 in LLM costs, while a complex 10-minute inbound support call could use $0.15. Budgeting accurately requires understanding your average conversation profile.

3. Failed Call Costs

Not every outbound call connects. You may pay for:

• Vapi: Charges start when the call connects (including answering machines)
• Retell: Similar to Vapi -- charges on connection
• Bland AI: Charges only for connected calls with answering machine detection
• Edesy: Charges only for meaningful connected conversations

If 60% of your outbound calls go to voicemail, answering machine detection becomes a significant cost factor. A platform that charges for every connected second including voicemails will cost 40-60% more in effective per-conversation cost.

4. Telephony Surcharges

International calling, toll-free numbers, and SMS add costs that are not reflected in base per-minute rates:

5. Scaling Costs Beyond Voice

As your operation grows, you will likely need:

• CRM integration: Vapi and Retell require custom development; Bland and Edesy offer native integrations
• Analytics and reporting: Advanced analytics may require third-party tools ($50-$500/month)
• WhatsApp/SMS follow-up: Additional channels add per-message costs on most platforms; Edesy includes these natively
• Compliance and recording storage: Call recordings require storage; some platforms charge for long-term retention

Frequently Asked Questions

Are there free tiers available for testing?

Vapi offers a free tier with limited minutes. Retell AI provides 60 free minutes for testing. Bland AI offers a trial with a small credit. Edesy provides a guided demo and trial period. All platforms allow you to evaluate the product before committing to paid plans.

How do costs change if I use a cheaper LLM?

On Vapi and Retell, switching from GPT-4o to a lighter model like GPT-3.5 Turbo or an open-source model can reduce LLM costs by 70-90%. However, conversation quality, instruction following, and function calling reliability typically decrease. Test thoroughly before optimizing for cost -- a cheaper model that qualifies 30% fewer leads costs far more than the LLM savings.

Do any platforms offer annual pricing discounts?

Bland AI and Edesy offer discounts for annual commitments, typically 10-20% off monthly rates. Vapi and Retell are primarily usage-based without annual commitment discounts on the per-minute rate, though enterprise agreements may include favorable terms.

What happens if I exceed my committed volume?

Most platforms with volume commitments charge overage at the standard (non-discounted) per-minute rate. Bland AI and Edesy allow flexible volume adjustments with advance notice. Vapi and Retell do not have volume commitments -- you pay for what you use.

How do I estimate my monthly minutes accurately?

Use this formula: Monthly minutes = (Number of calls per day) x (Average call duration in minutes) x (Working days per month) x (Connection rate). For outbound calling, assume a 30-40% connection rate and 2-4 minute average call duration. For inbound, use your current call volume data with an average handle time estimate.

Are there minimum commitments?

Vapi and Retell have no minimum commitments beyond their free tier limits. Bland AI's enterprise pricing requires a 50,000 minute/month minimum. Edesy offers plans at various tiers with different minimum commitments. Check current terms directly with each vendor.

Calculate Your Specific Costs

Pricing comparisons based on averages only go so far. Your actual costs depend on your call volume, average call duration, connection rate, required features, and growth trajectory.

Use the Edesy ROI Calculator to model your specific scenario. Input your current call volume, average call duration, and conversion rates to see projected costs across platforms and calculate the net ROI of switching to AI voice agents.

The cheapest platform is not always the best value. Factor in conversation quality, integration ease, support responsiveness, and the total cost of your communication stack -- not just the per-minute voice rate.
