AWS cost reporting is far from great. Its hard to learn current(daily) charges; RI is completely hidden and only visible in the final bill, blended; there's no way to limit the spending and the detailed reports are in csv, not user-readable.

Yes, there aren't great AWS provided tools, but the data is there. We happen to use Cloudability, though I'm sure there are other good tools, maybe even free ones.
