How this estimate is calculated

Launch snapshot: $175,627.15 at 3.125%. First modeled payment: November 1, 2026. Assumed monthly principal and interest: $851.85, calculated across 296 payments to June 1, 2051. The actual payment was not supplied.

Monthly interest rounds to cents. One-time principal is applied immediately; recurring extra begins with the next modeled payment. Escrow, fees and lender timing adjustments are excluded. These are illustrations, not lender payoff quotes.
