This is acknowledging a point of sale rebate is not the same as a tax credit right?
Not sure why you think it would.
Since the entire point was you're not paying in cash
either way you are instead taking a loan since loans are so cheap.
The only thing a point of sale rebate does in that case is make the loan a little smaller... so your monthly payment might slightly smaller for the 5 or 6 years or whatever you have the loan.
Though.... I suppose in this case (investment) it's arguable the point of sale rebate is
worse.
Let's check the math on that!
With the POS rebate you're effectively just "saving" a small amount each month for 5 or 6 years because the borrow amount is smaller by that rebate.
With the tax credit you're potentially saving $7500
right now (if you're someone who say sets aside a portion of cap gains the credit will offset throughout the year)-or at most less than a year from now (when you file) in one shot, which you could invest in full.
For example let's say you're taking a 60k loan at 2% in June with EITHER a $7500 tax credit, or a $7500 POS rebate. It's assumed your normal income can cover a car payment either way (if it can't you probably shouldn't be buying this).
(Either way whatever cash on hand you have can be invested, at likely much better than 2% return- so that's irrelevant to the math either way)
So...on a 72 month loan you're paying $885 a month on 60k...or $774 a month on 52.5k
The POS rebate means that over the next 6 months you will save $111 per month. Come January you'll have $666 in "saved" cash you could invest!
But...with the tax credit you have
an extra $7500 right now (if you're someone who puts tax $ aside all year apart from W2 withholdings, as many investors do)... or at worst you have $7500 extra in January you'd have otherwise had to give the IRS for your tax obligation for the year.
So you've got over 10x as much money to invest and grow by no later than 6 months after car purchase.
Now... the POS buyer will keep 'saving' his 2% of 52.5k ($111 a month) and you'll keep earning a lot better than 2% on your extra $7500 you invested.
The POS buyer won't reach $7500 "extra" money until month 68 of the 72 month loan.
So yeah, now that I really think about it- the POS rebate genuinely is worse if you're someone who can manage to beat 2% return on investment.
Now- don't get me wrong... the POS rebate is "better" for folks who don't understand the credit anyway, or who aren't going to be investing for good returns in the first place, they just want "the lowest monthly" they can get without caring if it's really "costing" them in the long run.
Which is why that's what the new EV credit is probably gonna be.
But mathematically speaking I'm sure
much happier (and richer) having had $7500 extra actual money 3 years ago to buy Tesla stock with, than having a $100ish buck a month cheaper loan payment.
