A lower repayment can come from a lower rate, or simply from taking longer to repay the debt. If you have 25 years remaining and the replacement loan resets to a fresh 30-year term, your monthly repayment can fall partly because the principal is now spread over another five years, not only because the rate improved.
An illustrative example
| Scenario ($500,000 balance) | Approx. monthly P&I | Approx. total interest if held to term |
|---|---|---|
| Current: 6.50%, 25 years remaining | $3,376 | $512,811 |
| Proposed: 6.00%, reset to 30 years | $2,998 | $579,191 |
| Proposed: 6.00%, keep 25 years | $3,222 | $466,452 |
Illustrative mathematical example only, using a constant rate and repayment pattern for simplicity. It shows why the same proposed rate, at two different terms, produces genuinely different outcomes, a lower headline repayment (the 30-year reset) but roughly $66,000 more total interest than keeping the original 25-year term at the same lower rate.
Why this needs two comparisons, not one
The only way to see the real trade-off is to compare the proposed loan using both the lender’s proposed term and your existing remaining term. The Refinance Workbench tracks your longest current remaining term against your longest proposed term automatically, and flags it prominently whenever the new term is longer, so a lower repayment never quietly hides a longer payoff.
What to prepare
- Your exact current remaining term, not just the original loan term
- Ask any proposed lender for the option of keeping your existing remaining term rather than defaulting to a fresh maximum term
- Compare total interest over a realistic holding period, not just the monthly repayment
Next step: run your own current and proposed terms through the Refinance Workbench to see whether a term reset is quietly part of your comparison.
