What the tool does, how to run it, and what to expect from the result.
Each loan's monthly payment uses the standard amortization formula from its principal, annual rate, and term. A lower monthly payment (often from a longer term) can still mean a higher total cost once all the interest is added up; this calculator shows both numbers side by side so the tradeoff is visible.
