Calculate the new payment using the remaining loan balance
Start from the current unpaid principal, time remaining, note rate and any prepayment or escrow considerations. A new fifteen-year or other shorter-term note may reduce total interest compared with extending debt for decades, but the amount due each month can rise materially. A comparison should include escrow, insurance and mortgage-insurance changes, not only principal and interest. Ask the lender to model both the new required amount and the current loan's projected path.
- Find the existing balance, remaining term and current payment
- Request a full shorter-term mortgage scenario
- Include all costs, escrow and mortgage insurance in comparisons
Consider keeping your rate and paying extra principal
Homeowners can ask their servicer how additional principal payments work and whether any contractual restrictions apply. For a favorable existing fixed rate, voluntary extra payments may create flexibility that a mandatory higher refinance payment does not. This approach does not automatically reproduce every benefit of a shorter-term loan, and interest costs depend on each schedule. Compare both payoff dates and total remaining interest using realistic payment assumptions.
- Ask how to designate an extra principal-only payment
- Model the current loan with a consistent extra amount
- Preserve adequate emergency reserves and cash-flow flexibility
Include the refinance costs and likely time in the home
A refinance may involve lender fees, title charges, appraisal expenses and prepaid items even when advertised as low-cost or no-cost. Rolling eligible costs into the new balance changes the economics. If the homeowner expects to sell or refinance again relatively soon, the closing charges may outweigh expected savings. Request Loan Estimates using the same closing date assumptions and use the comparison disclosures rather than relying only on a new monthly figure.
- Add lender, title and other actual financing costs
- Compare total interest and principal at future milestones
- Do not reset the term or lock a rate without reviewing the written offer
