Calculation method
Calculation method
Each option uses level monthly amortization. Entered borrowing cost is scheduled interest for the current loan versus replacement interest plus upfront refinancing costs.
Entered monetary components use exact fixed-decimal arithmetic. Amortizing comparisons reuse the reviewed stable loan schedule and round only for presentation.

Descriptive comparison
These tools describe entered cash flows and contract terms. They do not recommend a lender, lease, refinance, incentive, or purchase.
International scope
No currency, country, tax, lender rule, distance system, credit eligibility standard, or consumer-protection outcome is assumed.
Calculator-specific assumptions
The payoff balance is visitor-entered because a lender payoff quote can differ from a statement balance. Costs are modeled as paid upfront, not financed. The comparison is descriptive, not a recommendation.
