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

"Inputs","Value","Unit"
"Old setup cost on retained volume","2400","currency"
"Proposed remaining cost on retained volume","800","currency"
"Incremental administration and concessions","100","currency"
"Contribution per lost repair","900","currency"
"Unreplaced payment-related lost repairs","2","number"

"Results","Value","Unit"
"Monthly benefit before lost work","1500","currency"
"Break-even lost-repair threshold","1.6666666666666667","number"
"Net monthly effect after lost work","-300","currency"

"Calculation detail","Value","Unit"
"Comparable processing cost reduction","1600","currency"
"Incremental administration and concessions","100","currency"
"Lost contribution entered","1800","currency"
"Annualized same-scenario effect","-3600","currency"

"Assumptions"
"All defaults are illustrative and do not predict customer behavior or savings."
"Old and proposed processing costs use the same retained volume to avoid counting fees avoided on lost jobs as program savings."
"Lost contribution is net of avoidable costs and any genuinely recovered contribution from replacement work."

"Result notes"
"A negative benefit or threshold means the entered proposal fails the cost comparison before lost work."
"Annualization assumes the same monthly result repeats; it is not a forecast or savings guarantee."
"Verify the actual program, disclosures, card-type treatment, local requirements, and customer response separately."
