The Three Cost Components
Running OpenClaw has three cost components. OpenClaw itself is free and open source — there is no license fee, no subscription, no per-seat charge. The costs come from the infrastructure it runs on and the AI models it uses.
1. AI Model API costs — the cost of sending prompts to and receiving responses from AI models. This is typically the largest cost component and varies dramatically based on which model you use and how many messages your agent processes per day.
2. VPS/hosting costs — the cost of the server that runs OpenClaw. This is a fixed monthly cost regardless of how much you use the agent. Ranges from $0 (Oracle Cloud free tier, Raspberry Pi) to $20+/month for premium VPS instances.
3. Ancillary costs — domain name ($10-15/year), optional backup storage, optional monitoring services. These are small and most operators either already have them or can skip them.
For this breakdown, we will focus on the first two since they represent 95%+ of the total cost. We will calculate everything on a per-day basis since that is how most operators think about running costs.
AI Model Costs Per Day
AI model costs depend on two things: which model you use and how many messages your agent processes. Here is a breakdown assuming 100 messages per day with an average of 500 input tokens and 300 output tokens per message (a typical conversational workload).

The cost range is enormous. Claude Sonnet 4 at 500 messages per day costs $3.00/day ($90/month). DeepSeek V3 at the same volume costs $0.23/day ($7/month). Ollama with a local model costs nothing regardless of volume.
The quality difference is real but smaller than the cost difference. For many OpenClaw use cases — message routing, simple Q&A, appointment scheduling, basic CRM updates — DeepSeek V3 or GPT-4o mini produce perfectly adequate results at a fraction of the cost. Reserve Claude Sonnet or GPT-4o for complex reasoning tasks using OpenClaw's multi-model routing.
A common cost-efficient configuration: use DeepSeek V3 or GPT-4o mini as the primary model for routine tasks, and route complex tasks to Claude Sonnet. This hybrid approach can reduce your daily model cost by 60-80% compared to running Claude for everything.

Hetzner offers the best value for European operators. Oracle Cloud's Always Free tier is genuinely free and sufficient for personal OpenClaw deployments. For North American operators, Contabo and Hostinger offer strong specs at competitive prices.
If you are running Ollama alongside OpenClaw for local models, you need more RAM. Bump to a plan with 4-8GB RAM, which typically costs $5-15/month ($0.17-0.50/day).

The "Business premium" line assumes 500 messages per day with Claude Sonnet. Most solo operators and small businesses fall in the $0.20-1.00/day range, which works out to $6-30/month. Compare this to managed AI agent platforms that start at $50/month and quickly scale to $200-500/month.
How to Reduce Your Daily Cost
Use multi-model routing. OpenClaw's model router can send different tasks to different models. Route simple tasks (greetings, FAQs, routing decisions) to GPT-4o mini ($0.03/day for 100 msgs) and complex tasks (reasoning, analysis, creative writing) to Claude Sonnet. Most agents process 80% simple tasks and 20% complex tasks, so this can cut model costs by 60-70%.
Use DeepSeek V3 as your primary model. For many use cases, DeepSeek V3 produces results comparable to GPT-4o at roughly one-tenth the cost. Test it with your specific use case before committing, but many OpenClaw operators have switched their primary model to DeepSeek with minimal quality impact.
Implement response caching. OpenClaw supports response caching for identical or similar prompts. If your agent frequently answers the same questions, caching can reduce API calls by 20-40%. Enable it with OPENCLAW_CACHE_ENABLED=true.
Optimize prompt length. Shorter system prompts and more concise conversation context reduce token count per message. Review your agent's persona prompt and trim unnecessary instructions. Every 100 tokens you remove from the system prompt saves that cost on every single message.
Set usage limits. Use OPENCLAW_DAILY_TOKEN_LIMIT to set a maximum daily token spend. This prevents runaway costs from echo loops, spam, or unexpectedly high usage. When the limit is reached, the agent can fall back to a cheaper model or send a "please try again tomorrow" message.

OpenClaw is 3-20x cheaper than managed platforms for comparable functionality. The tradeoff is that you manage your own server, handle updates, and troubleshoot issues yourself. For operators comfortable with Docker and basic Linux administration, the cost savings are substantial. For teams that want a fully managed experience and do not have technical staff, managed platforms may be worth the premium.
Frequently Asked Questions
How much does OpenClaw cost per day to run?
Total daily cost ranges from $0.17/day (Ollama + cheap VPS) to $3-5/day (Claude/GPT-4o + premium VPS with heavy usage). A typical personal deployment using DeepSeek on a $5/month VPS costs about $0.22/day. A business deployment using Claude Sonnet on a $10/month VPS costs about $1-2/day depending on message volume.
What is the cheapest way to run OpenClaw?
The cheapest option is running OpenClaw on a Raspberry Pi 5 with Ollama and a local model. Hardware cost is about $100 one-time, electricity is about $0.01-0.02/day, and there are no API costs. The cheapest cloud option is a $3.50/month VPS (Hetzner or Oracle Cloud free tier) with DeepSeek, totaling about $0.17/day.
How much do AI model API calls cost for OpenClaw?
For 100 messages per day: Claude Sonnet costs about $0.60-0.80/day, GPT-4o costs about $0.50-0.70/day, DeepSeek costs about $0.03-0.05/day, and Ollama (local) costs $0/day. The cost scales linearly with message volume and conversation length.
Is OpenClaw cheaper than managed AI agent platforms?
Yes, significantly. Managed platforms like Relevance AI, Voiceflow, or Botpress charge $50-500/month for similar capabilities. OpenClaw's self-hosted model costs $5-60/month for most deployments. The tradeoff is that you manage the infrastructure yourself.
