Saleable area is a market term that usually means super built-up area: the flat plus a share of common areas. Carpet area is the usable floor inside the walls and, for RERA-registered projects, the figure the agreement for sale must state.

When Saleable area matters
Saleable area tells you what a quoted rate per square foot is applied to, and sometimes what maintenance is billed on.
When Carpet area matters
Carpet area is what you compare, check in the agreement and measure at handover.
In more detail
The term varies by city and seller. In commercial property the same idea is often called chargeable area or leasable area. Whatever the name, ask for the carpet area beside it.
The ratio between the two is the loading, set by the builder. Two flats with the same saleable area can have quite different carpet areas.
