Pay Off the Car Loan Early, or Invest the Difference?
There is a clean way to answer this without guessing.
You have some extra money each month.
One voice says kill the debt.
Another says the market will do better.
Here is how to decide without relying on a feeling.
Start with the interest rate
Paying off a loan is a guaranteed return equal to its interest rate.
An investment return is not guaranteed.
So the comparison is between a certain return and an uncertain one.
A workable rule of thumb
✅ High-interest debt — credit cards, anything in double digits — pay it first, always
✅ Low-rate debt, roughly under 4% — investing the difference often makes sense
✅ In between — split it, and let both make progress
The things the math leaves out
Debt has a psychological weight that a spreadsheet does not capture.
Some people simply function better with fewer payments, and that is a legitimate input.
Also check the loan agreement for prepayment penalties before making a lump-sum payment.
Before either one
Make sure the emergency fund exists.
Paying down a loan aggressively and then putting an emergency on a credit card undoes the whole exercise.
As always: this is general education, not financial advice. For your numbers, talk to a licensed advisor.
