Explain the rate, fee and balance terms
Principal
The loan balance on which interest is calculated. It can include financed fees, so it may differ from cash received.
Note interest rate
The contractual interest-rate input used by a payment formula. Keep it separate from the disclosed APR.
Comparison / holding horizon
The future point at which two scenarios are compared on the same basis.

Equal end-of-month payments; no taxes, escrow, insurance or irregular first period. Fees are cash-paid separately. Resetting examples does not change saved tools elsewhere.

How to interpret the result

Cash saving compares cumulative installments less the cash closing cost. Balance-adjusted cost saving also includes the remaining balance of each loan. A smaller installment can come from extending the term rather than a lower overall cost. These are nominal dollars with no discounting or tax effect.

Before deciding, match the written terms

These manual checks are not an approval or recommendation.

The timeline continues through both loan terms. “First recovery” means the first nonnegative modeled month; it may reverse later. Choose a horizon within the longer term and review the balance columns.
