AFE Builder
Authorization for expenditure in US dollars. Example costs are editable; use current quotes and one consistent ownership basis. Contingency applies to the full subtotal; exclude any contingency already included in cost lines.
Subtotal: $3,450,000.00
Contingency: $345,000.00
Total AFE: $3,795,000.00
Total AFE = sum of costs × (1 + contingency / 100).
