Tell me how? The scenario was that we both started with $7000 dollars. I used mine to pay cash for a car. You invested your $7000 no additional investment earning. You then financed the same $7000 car I paid for with a car not of $132 per month for 5 years. For 5 years while you pay your car payment, I invest $132 per month instead. In your post you said that your investment balance at the end of 5 years would be $8,933.97. You then said that my monthly investment would yield $9190.23. $9190.23 - $8933.97 gives you a total of $256.26.
The bottom line for me is that you're putting less money per month into investments when you're making monthly debt payments at the same time.
Yes, you'd have $256.00 more but you would have had to spend more to get there.
I spent $7000 (the initial sunk cost of my investment) plus $7926.00 (for the car) for a total of $14,926.00.
You spent $7926 (the sum of all your investment contributions) plus $8933.97 (the future value of the $7000 sunk cost to buy the car) for a total of $16,859.97.
...at least, I think so... To be honest, I got a C in ECON in college... (If we're being really real, I got a C in everything...)
But, regardless, this is only even close because we're using 5% all around for simplicity. If we used today's interest rates with today's expected yield on investment, it wouldn't even be close.
