# Build your plan

Configure a yearly or monthly plan: pick yearly service hours, the services you need, and support. The page shows an instant estimate and a shareable link.

## How the estimate works

- Hours per year: 50–50,000. Hours are a shared pool across services, billed at the rate of the highest-priced active service.
- Graduated volume discounts (each band applies only to the hours inside it): 0–250 hours at 100%; 250–1000 hours at 85%; 1000–5000 hours at 70%; 5000–20000 hours at 55%; 20000–∞ hours at 40%.
- Monthly billing adds 20% to the annual price.

A plan is encoded in the URL: `/plans?state=<base64url JSON>`. The JSON has `v` (1), `hours`, `services` ({ `aiDubbing`, `encoding` } booleans), `standardSupport` (`basic`, `pro`, `enterprise`), `liveSupport` (hours per year for `standardHours`, `extendedHours`, `outOfHours`), `cycle` (`annual` or `monthly`), and `currency` (`USD`, `GBP`, `EUR`).
