Assumptions and example inputs

Example inputs are editable placeholders to show how the calculator works. Results are estimates, not quotes or approvals, and they do not use live rates or lender pricing.

Blended rate is a balance-weighted average of the entered note rates, not APR. Fees, variable-rate changes, and mortgage insurance are excluded.
Payments assume fixed rates. An interest-only loan retains its principal balance and has a balloon payment at the end of its entered term.
