# Prices

> Every figure carries its basis; show it.

A variant's `prices` list holds one row per source and state with `ex_showroom_inr`, optional `high_inr` (the top of a band), `source_kind` (`maker`, `dealer`, `reported`, `estimate`), `state_code` and `observed_at`. Listing rows summarise the best available figure as `price_from_inr`, `price_to_inr`, `price_kind` and `price_as_of`.

Rules we ask you to keep: a `reported` or `estimate` figure is shown with a star or the word, never as the maker's price; a band is shown as a band; the date travels with the figure.

A variant's sheet also carries `on_road`: the on-road figure by state, computed from the state's road tax and registration rules on the national ex-showroom price, with the rule's date. A dealer's own state quote, where one exists, wins over the computed figure. `launched_at` on a variant is the maker's launch date, which drives the new-launch tracker; `lifecycle` tells `on_sale` from `discontinued`, and a discontinued variant keeps its last listed ex-showroom figure.
