The AMEX Centurion card has annual fees of, depending on the country, up to the equivalent of 5402USD for Taiwan. There are also one-time joining fees of up to 7500USD.
Now these anodised titanium cards clearly have a lot going for them in terms of prestige, but are they financially worthwhile? How could you use the card to make back that five grand?
I am interested in specific spending patterns which would make it financially worthwhile. For example, travel insurance is a good benefit, but cards with much cheaper fees offer it too. Does the card have better insurance, which you couldn't get for free with another card? If so, how much would you have to travel for it to be worth it? Or maybe having no limit allows you to make up the annual fee purely through increased interest in your savings account, but if so, how much are we talking about?
