I have AMT due as my FTC is being limited. The ratio seems to be Wages less FEIE and Housing less share of standard deduction divided by AGI (no deduction). Correct?

AGI being Wages + non foreign interest less FEIE and Housing (i.e., no adjustment for the standard deduction). As that amount is higher than "normal" (non-AMT) tax due less "normal" (non-AMT) FTC, I have AMT. Hope that makes sense. Very confusing.....
