The 20/4/10 Rule Keeps Your Finances Under Control When Buying A Car

Overextending your bank account when buying a new car can leave you in a lurch if a financial crisis strikes before it's paid off. Be sure to use the simple 20/4/10 rule to avoid taking on a bigger car loan than you can comfortably absorb within your budget.

Michael Kling at Wise Bread shares the easy-to-remember rule:

  • Put down at least 20 per cent
  • Finance the vehicle for no more than four years
  • Keep total monthly vehicle expense — including principal, interest and insurance - under 10 per cent of gross income

Having at least 20 per cent saved up beforehand lets you pay off the car sooner, and with more manageable payments. Keeping your financing term short limits the amount of interest you'll pay, and allows you to drop costly comprehensive insurance coverage sooner. Finally, keeping your monthly expenses at less than 10 per cent of your income gives you a little more flexibility if you're hit with an unexpected bill or lose your job.

This is a simple rule, but it's very easy to keep in the back of your mind when you're starting your car search.

How Much Should You Spend on a New Car? [Wise Bread]

    Mr and Mrs Average with a mortgage wonder why it takes 20 plus years to pay off their home, when there's a shiny new car or two in the garage - bought with car loans. How about a second-hand car, with 100% deposit? There's no need to keep up with the Jones', they'll be in debt until their 59. Just sayin'

      I have only ever purchased second hand cars. Apart from the fact that they are substantially cheaper, i happen to like manual clutch (and will only drive manual clutch), and i hate all the electronic auto-everything that new cars have these days - so i really only can purchase second hand.

      ssshhhhhh....I need someone to buy that shiny new Audi Q5 today so that I can buy it off them in a few years time....
