Affordable healthcare act question

For a family of two, what’s the cutoff limit for receiving subsidies to pay for the new mandate?

From Kaiser Family Foundation:

It’s based off the poverty level, IIRC.

To add, I believe it caps out at 400% of the poverty level, but I could be wrong about that.

Interesting, thank you, but why does it only give single adult or family of four? I’m married with no kids. That doesn’t seem to take that into account.
