“It’s dangerous to think about a big purchase, like a house or a car, in monthly terms,” says Jim Wang, a blogger at Bargaineering.com. “It doesn’t illustrate how much of your total wealth has to be surrendered in order to own that house or car.”
“It’s also easier to swallow $200 a month instead of a five-figure number, so salespeople are trained to go after the monthly number,” he says. Whenever a salesperson is giving you financial advice, he says, step back and evaluate whose best interest they have at heart, yours or theirs. Always do the math on what the purchase will cost you in the long run.
“I’d say focusing on the monthly price of anything, and ignoring all else, is terrible advice,” Wang says. “While it’s important to look at that number for the purposes of budgeting, you always want to know how much you’d be paying in total.”
