Refinance Same-Term Calculator
Restarting into a new 30-year loan lowers the payment but extends interest. The same-term comparison runs the new rate against your remaining years — arithmetic only, not a recommendation. Here: $275,000 at 6.625% with 20 years left vs 5.875% at the same 20-year payoff window.
That same-term payment sits beside the fresh-30 payment in every result so you can see both numbers without hunting. Break-even and lifetime interest comparisons are still shown.
Controls below let you change remaining years, new rate, and closing costs. Copy link shares paper and layout settings only — never loan figures. Not financial advice.
