Example
Paying off high-interest debt can produce a guaranteed return equal to the avoided interest cost. Investing may have a higher expected return in some cases, but market returns are uncertain.
Common assumptions
This calculator uses simplified assumptions. Real results can vary based on taxes, fees, changing rates, minimum payment rules, market performance, and behavioral factors.

Is paying off debt always better?
Not always. The answer depends on the debt interest rate, expected investment return, risk tolerance, liquidity needs, and time horizon.
What debt should I prioritize?
High-interest debt usually deserves attention first because the avoided interest cost is often significant and predictable.
Does this include taxes?
No. Tax effects are not explicitly modeled, so treat the result as a planning estimate.
