I've noticed a pattern in the various threads by people asking for help with their finances and debt situations. Invariably, they have one or more expensive car loans that the rest of us deem out of proportion to their income. Many of us chime in with the advice to sell a car or two and replace them with more affordable options.
I think we're all familiar with guidelines on buying a home:
Purchase price shouldn't exceed 3 times your income.
Monthly payments should be no more than 28% of monthly income.
Total debt servicing shouldn't exceed 36% of income.
But I don't recall any rules of thumb for car buying. For many young adults and folks just starting out, it is the car that is the largest purchase they've ever made. Even for those of us more established in life, some guidance is needed in deciding how much to spend for a vehicle. Despite our advice, once someone already has a car payment they can't afford, there is often very little they can do about it. It would be much better to avoid that situation in the first place.
So my question is this: Are there any common guidelines or rules of thumb to help people decide how much they can afford to spend on their cars?
