Student Loan Payoff vs. Invest Calculator FAQs

1. Should I take the calculations from the Student Loan Payoff vs. Invest Calculator and apply them directly to my financial situation?

No. The calculations here are for estimation purposes only. It’s important to note that this calculator in particular also factors in a lot of assumptions that may not hold true, such as annual expected return on investments as well as long-term tax rates. Additionally, there are other factors that this calculator cannot account for. As always, we recommend consulting a finance or tax professional when it comes to making your own financial decisions.

2. What value do I use for the “Extra Money Payment Amount” field?

This calculator assumes that you have extra money left over each month after you pay your monthly student loan bill. Enter the amount you have left over in the “Extra Money Payment Amount,” field. The calculator will then calculate where it may be best for you to apply this money (towards your student loans or an investment account).

If you do not have any money left over in your budget after paying your student loans, this calculator will not be helpful to you.
