Assumptions & Notes
- Payments are fully-amortizing and computed monthly using your inputs.
- “Stay” uses the remaining amortization and term; refinance and blend use their own amortization/term.
- Penalty estimates are simplified (3-month interest or simple IRD). Lender methods vary; your agreement governs.
- Blended rate uses a simple time-weighted average of current vs offered rate. Actual lender formulas can differ.
- Break-even is approximate, based on cumulative interest saved vs. any upfront cash paid.
