Audited planning profile
This lean weekly profile applies a 0.75× editable baseline across 7 model periods to the installment purchase capacity model.
Round capacity down to a whole deliverable and keep spare room for peaks, rework or downtime. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Account for weekday/weekend variation and incomplete weeks.
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.
