Ventrova  LLM Cost Calculator
Free tool

What is your LLM feature actually going to cost per month?

Pick a model, set your token counts and volume, get an instant monthly estimate. No signup, nothing sent to a server, everything below runs in your browser.

Snapshot list prices, illustrative only. Provider pricing changes often, check the provider's pricing page for current rates, or use Custom below for an exact number.

Rough math: (daily active users) × (requests per user per day) × 30.

Estimate only: ignores caching discounts, batch pricing, rate-limit overage, and provider-specific fees. Actual bills vary.

The number that actually bites is the one you don't see coming

Get notified before a cost or quality spike, not after the invoice

We're building Sentinel Watch: a spend and quality watchdog for LLM features. It tracks your real token spend against a budget, flags sudden cost spikes (a prompt regression, a runaway loop, a traffic surge), and alerts you if response quality drifts, before it shows up as a support ticket or a surprise bill. It doesn't exist yet. We're validating demand before we build it.

Thanks, you're on the list. We'll reach out when Sentinel Watch is ready to test.

No spam, one email when it's ready to try. You can also just email business@ventrova.dev directly.
