…the API offers scalable access to powerful GPT models like gpt-3.5-turbo and gpt-4-turbo.
💰 ChatGPT API Pricing Breakdown (As of May 2025)
Keywords: ChatGPT API pricing, GPT-4 API cost, OpenAI token pricing
OpenAI charges based on tokens used—think of tokens as pieces of text (~750 words = 1,000 tokens). Here’s the latest price table:
📊 ChatGPT API Pricing Table
Model | Input Price (per 1K tokens) | Output Price (per 1K tokens) | Use Case |
gpt-3.5-turbo | $0.0005 | $0.0015 | Fast, low-cost tasks |
gpt-4-turbo | $0.01 | $0.03 | Advanced reasoning, premium AI |
Embeddings (text-embedding-3-small) | $0.00002 per 1K tokens | N/A | Search, recommendations |
📌 Prices are current as of OpenAI Pricing Page and subject to change.
🧩 How to Estimate Your ChatGPT API Costs
Keywords: ChatGPT usage cost, OpenAI budget planning, GPT token calculator
To estimate your monthly expenses:
Estimate token usage per request (e.g., a 200-word prompt + 500-word response ≈ 900 tokens).
Multiply by your daily volume.
Apply the respective input/output rates.
🧮 Example: Daily 1,000 queries using GPT-4 Turbo
Avg. 900 tokens per query (input + output)
1,000 queries/day → 900,000 tokens
Cost = 0.01*500K + 0.03*400K = $5 + $12 = $17/day
Monthly = ~$510/month

Keywords: GPT-3.5 vs GPT-4, ChatGPT API options, AI tool selection
Feature | GPT-3.5-Turbo | GPT-4-Turbo |
Cost | Very low | Higher |
Speed | Fast | Slightly slower |
Output quality | Good | Best |
