"Basis","This planning scenario uses the values entered. It is not an industry benchmark or a quote."

"Inputs","Value","Unit"
"Total standalone value of package components","3300","currency"
"Actual package selling price","2970","currency"
"Standalone value of canceled component","900","currency"
"Agreed retained delivered-service value","180","currency"
"Completed refunds for this component","100","currency"

"Results","Value","Unit"

"Refund remaining after prior refunds","530","currency"

"Calculation detail","Value","Unit"
"Package allocation factor","90","percent"
"Prior completed component refunds","100","currency"

"Assumptions"
"Starting values are examples, not market benchmarks or payment quotes."
"Use one currency and a consistent before-tax basis. Work out taxes and program-specific adjustments separately."
"The full package selling price was paid before cancellation; prior refunds relate only to the component being modeled."
"For deposits or installments, reconcile the revised agreed total against actual net payments to find the unpaid balance or overpayment. These cash-refund outputs do not apply, and the selling-price input must never be replaced with deposit cash."

"Result notes"
"A zero standalone total makes allocation unavailable. The removed component must not exceed the total."
"This model does not decide refund entitlement, tax adjustments, surcharge reversal, or whether a retained amount is enforceable."
