A contractor builds a warehouse extension under a cost-plus contract paying allowable costs plus a 12% fee. Allowable costs of materials, labour and overhead total €180,000, so the fee is €180,000 times 0.12, or €21,600. The client pays €180,000 plus €21,600, or €201,600 in total — a fee that rises automatically if allowable costs run higher.
