Should You Pay Off Debt or Invest?
It's one of the most common money questions, and the honest answer is 'it depends on the numbers.' Here's a framework — and how to let the math decide instead of guessing.
Start With the Guaranteed Return
Paying off a debt earns you a guaranteed return equal to its interest rate. Clearing a 22% credit card is like earning a risk-free 22% — almost impossible to beat in the market. High-interest debt is therefore usually the first priority.
Compare the Rate to Expected Returns
For lower-rate debt (say a sub-5% mortgage), the calculus changes: long-run market returns have historically exceeded that, so investing the surplus may build more wealth — at the cost of certainty. There's no universally right answer; it's a trade-off between a guaranteed return and expected (but variable) growth.
Don't Skip the Basics
Two things usually come before either: capturing any employer 401(k) match (an instant 50–100% return) and holding a starter emergency fund so a surprise doesn't push you back onto high-interest debt.
Let the Dollar Impact Rank It
Rather than debate it abstractly, Lodestar computes the estimated annual dollar impact of each option from your actual numbers and ranks them — so you can see whether paying down a balance or investing the same dollars does more for your net worth, and simulate either against your forecast. Confirm any tax specifics with a CPA.
FAQ
Should I always pay off debt first?
Usually for high-interest debt (like credit cards). For low-rate debt, investing the surplus can win over time — it's a trade-off between a guaranteed return and expected market growth.
What about my employer 401(k) match?
Capture it first if you can — a full match is an immediate 50–100% return that's hard to beat anywhere else.

No — it's educational. Lodestar gives you the numbers and a framework; confirm decisions, especially tax, with a qualified professional.
