Loan Comparison Calculator

Use the loan comparison calculator to compare up to three fixed-rate offers by payment, scheduled interest, fees and total repayment.

Loan details

Side-by-side result

Payment and balance use the entered interest rate; APR remains a separate disclosed comparison measure. Cost through the shared horizon equals interest paid through that month plus entered upfront fees. Confirm whether fees are paid separately or financed.

Collect the written terms for each lender

  • Written offers for the same amount and product type
  • APR, term, payment and fee disclosures for each offer
  • Rate-lock or quote-expiration details
  • Prepayment and optional-product terms

Put every offer on the same footing

Enter each offer exactly as disclosed.

Set one holding horizon and compare cost through that month.

Compare matched terms before testing longer terms.

Challenge the offer with the smallest payment

A smaller payment requires a longer loan

Enter two written offers for the same principal, first exactly as quoted. If one uses a longer term, run a second comparison after matching the terms. Compare scheduled interest and entered fees with the monthly payment so the cash-flow benefit is not mistaken for a lower-cost loan.

Separate payment relief from borrowing cost

A lower payment may come from a longer term. Compare the cost through one realistic holding period and the full scheduled total before treating that payment as a saving.
