If we assume a generous pet lifespan of 15 years that's not unreasonable that's like $400/mo which depending on what your pet needs food wise and how much you spoil them is easily met
I bought my current car new 14 years ago. It has some issues that might be too expensive to fix so I might need to buy another car. My ideal car would be an electric car, but that is way too expensive for my budget. So I looked at hybrids. I might be able to make a hybrid work, but even a gas car will be stretching my budget.
And I plan to keep my next car until it breaks down - which hopefully would be about another 14 years.
I've never understood the mentality of 'its too expensive to fix'. $3000 is unobtainable, but $15000 just fine? My jeep needed a new engine, instead of buying a new car I just put a new engine in it. Saved me over ten grand and I've got transportation for at least the next ten years. Just fix your car, you'll be better off in the long run.
Cars devaluate around 50% every 3 years, so if you bought a 3 year old car instead of new, you could swap it every 7 years for the same cost. And if it holds some residual value, even more often than that...
Some manufacturers even offer warranties on 3 year old leasing returns.
As an average, those assumptions are downright modest. The cliche of a house with a white picket fence, a wife, 2.5 kids, a dog, and a mortgage line up pretty well with that.
Granted, this isn't everyone's dream, and it doesn't apply everywhere. But I would bet that the majority of people in this country would describe that as the cost to live that cliche.
