Why did they charge their cable bill to the credit card? To get the free miles, of course! More faux financial acumen at work. You step into a nasty negative-option trap to get a few pennies back a month. It ain't worth it. You can't spend your way to wealth!
The amount I spend would be about 1.7% of their pre-tax income - and looking at expenses as a percentage of annual income is another good way to spot excess spending - bearing in mind that of all those 1%'s you have to spend, you only get 100 of them, and frankly, most are spoken for by real needs and expenses like taxes, savings, food, and shelter.
And you know what? Frankly, I think $760 a year is too much to spend. I continually look for ways to cut this cost further, if I can. And my communications costs are largely tax deductible as part of my business, too.
Another way, as noted above, is to look at the cost in terms of percentage of annual income. Again, you get only 100 of these percentage points, and if you are paying 5% or more of your income to watch television, that is an staggeringly large amount of money.
What my friends are paying just to watch television and yak on the phone (and worse, text) is enough to make a car payment on a fairly nice used car. Should television cost as much as a car? I for one don't think so.
You can live better by living on less. $2000 a year is a lot of money particularly for people who claim to be broke all the time.
NOTE: If you go on vacation for more than a month or so, most cable providers and internet service providers will put your service on "vacation hold" while you are gone - at a far reduced rate. But pulling the plug from the almighty TeeVee is really a better option.
