Audited planning profile
This shared daily profile applies a 3× editable baseline across 1 model period to the installment purchase change model.
Use the absolute difference for budgeting and the percentage difference for comparing impact. Define a consistent allocation rule so shared usage is not counted twice. Use a typical day and separately test peak or exceptional days.
Variable rates, late fees, prepayment rules, credit-score effects, taxes and lender eligibility are not inferred.
Use the lender's current APR, fee schedule and payoff quote; preserve an emergency-cash margin.
