"Should I pay off my student loans or start investing?" doesn’t have a universal answer, but it does have a concrete framework: compare a guaranteed return against an uncertain one.
If a loan charges you 6% interest (a hypothetical example — check your own loan’s actual rate, which varies by loan type and origination date), every extra dollar you put toward it saves you exactly 6% a year, guaranteed, for as long as that debt would otherwise have accrued interest.
The stock market has no guaranteed annual return. Any specific number quoted for "the" average market return is a historical average over some period, not a promise for the years ahead — some years are sharply negative. Honest forecasting tools express this as a range rather than a single number.
The higher your loan’s guaranteed interest rate, the stronger the case for paying it down first, because you’d need an uncertain investment to beat a certain rate just to break even. A very low-rate loan tilts the comparison the other way. Many people split the difference — paying more than the minimum on debt while still starting to invest something.
This is a framework for thinking it through, not personalized advice for your specific loans. The 6% loan rate used below is a labeled hypothetical example, not a current real rate — check your own loan’s actual terms.
Not always — it depends on the loan’s interest rate. A high-rate loan is a strong case for paying it down first since that return is guaranteed. A very low-rate loan tilts the comparison toward investing sooner. This lesson gives you the framework, not a one-size-fits-all rule.
There’s no universal cutoff — compare your loan’s actual rate (check your loan servicer, since rates vary by loan type and origination date) against how much uncertainty you’re comfortable taking on for a potentially higher but unguaranteed return.
Yes, and many people do: paying more than the minimum on debt while still contributing something to investments, rather than treating it as all-or-nothing.
Investor education only — not investment advice, and never a promise of profit. Every investment can lose value.
