How to use Loan Comparison Calculator

  1. Enter the amount, rate, and term for up to three loan offers.
  2. Compare monthly payment, total interest, and total cost side by side.
  3. Use this before signing to see which offer is actually cheapest overall, not just which has the lowest monthly payment.

Limitations

  • A loan with a lower monthly payment often has a longer term and costs more in total interest — the side-by-side total-cost column is there specifically to catch that trade-off.
