Audit aid only. Your lender's official payoff quote and contract control. Precomputed-interest loans and lender-specific posting rules can differ.
How the estimate works
The calculator uses a basic simple-interest estimate: principal × annual rate ÷ 365 for daily interest, then multiplies that daily amount by the selected number of days. It adds known fees only when you enter them.
It does not model precomputed interest, contract-specific day-count rules, payment reversals, late charges, lender cutoffs or a scheduled payment that posts while the quote is open.
