Loan Comparison Calculator

Comparing loans properly is one of the most valuable financial skills, because the headline that lenders advertise — usually the monthly payment or the interest rate — rarely tells the whole story. Two loans can look similar on the surface yet differ by thousands of dollars in total cost once the term, rate and fees are all accounted for.

The trap most borrowers fall into is focusing on the monthly payment alone. A lower monthly payment feels more affordable, but it's often achieved by stretching the loan over a longer term — and a longer term means more payments and far more total interest, even at the same or a lower rate. The honest comparison looks at the total cost: the monthly payment multiplied by the number of payments, which reveals everything you'll actually hand over.

The interest rate, expressed as APR, is the next key factor. APR is more useful than the nominal rate because it folds in certain fees, giving a truer annual cost. When two loans have different rates and terms, comparing APRs alone still isn't enough — you need to combine rate and term into total interest paid to see which wins. A loan with a slightly higher rate but a shorter term can easily beat a lower-rate, longer-term loan on total cost.

This is exactly what a side-by-side comparison clarifies. By computing each loan's fixed monthly payment and then its total interest and total cost, you can see not just which has the lower payment, but which is genuinely cheaper over its life — and quantify the difference. Sometimes the cheaper loan has a higher monthly payment that's still well within budget, making the extra savings well worth it.

Beyond the numbers, consider features that don't show up in a simple comparison: prepayment penalties, variable versus fixed rates, origination fees, and flexibility. But the foundation of any sound decision is an apples-to-apples cost comparison, and that's what this calculator provides — letting you choose the loan that costs you the least, not just the one that looks easiest each month.
