How to Use the Monthly Spend Estimator

Enter your daily request count and average token usage. The estimator multiplies by your billing period and calculates the exact monthly cost for every model in our database. Results are sorted cheapest-first by default.

Tip: Use the presets to quickly model common scenarios. A "Hobby" project (100 requests/day) costs as little as $0.27/month on the cheapest models. A "Scale" deployment (100K requests/day) can range from $27/month to $13,500/month depending on your model choice.

Filter by provider to compare models from a specific company, or filter by tier to focus on budget, mid-range, or premium options. Click any column header to sort by that metric.
