Max exposure is based on your income and ability to pay.
In general most lenders top out at 50%.
That sounds reasonable.
I wondered where my total credit limits with Chase were derived from after I recently hit a ceiling with them after five new cards.
I just did a new calculation and seem to have hit their magic formula:
Reported income/2 (minus) annual debt payments
(in my case, basically a monthly mortgage and a car payment, plus a little monthly cc payments @ 1% or less)
So 50% of income is a good starting point, but debt load may be taken into account also.
