How our models work

Most bank calculators only show monthly savings. The Newston Terminal calculates the Total Lifecycle Cost of Debt. Our Mortgage Pivot tool factors in amortized interest resets, time-value of money, and closing costs to find your true break-even point in the 2026 rate environment.
