Audited planning profile
This lean five-year profile applies a 0.75× editable baseline across 60 model periods to the balance transfer buffer model.
Use the buffered result for planning and the unbuffered result as the transparent baseline. Treat the lean scale as a lower-bound plan and test whether essential fixed costs still fit. Treat maintenance, replacement and compounding assumptions as material over five years.
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.
