Stop Googling pricing pages. Every time you need to compare AI model costs, you open 5 tabs — OpenAI, Anthropic, Google, Mistral — and manually calculate what your workload would cost on each. Then a provider changes pricing and your spreadsheet is wrong.
We built a better way.
Free LLM Cost Comparison Calculator
Enter your daily token volume (input and output), and instantly see what every model from every major provider would cost you — daily and monthly. No signup. No paywall.
What makes this different
300+ models, one table. OpenAI, Anthropic, Google, Mistral, Cohere, DeepSeek, and more — all in one sortable, searchable view. Prices synced daily from provider APIs.
Quality scores included. Not just cost — we show quality scores from our Model Lab benchmarks, so you can find the models with the best cost-per-quality ratio. A model that costs 50% less but performs 80% as well might be the better choice for your use case.
Pareto frontier badges. Models marked "Best Value" sit on the efficiency frontier — no other model is both cheaper AND higher quality. These are your shortlist.
Real math, not estimates. Enter your actual daily token volumes. The calculator does the arithmetic: (input_tokens × input_price + output_tokens × output_price) / 1M × 30 days. Simple, transparent, correct.
Example: classification workload
A team running 1M input tokens and 100K output tokens per day:
| Model | Monthly Cost |
|---|---|
| GPT-4o | ~$120 |
| Claude Sonnet 4 | ~$102 |
| GPT-4o-mini | ~$18 |
| DeepSeek V3 | ~$12 |
That's a 10× cost difference between the most and least expensive option — for the same task. The calculator shows this instantly.
Why we built this
We're AISpendGuard — we help dev teams find and fix wasted AI spend. The calculator is step one: know what your models cost. Step two is tracking what you actually spend in production, detecting waste patterns, and getting actionable recommendations.
