Flower Math is a standard industry formula that teaches florists how to achieve a profit margin of 70% on the cost of flowers and supplies. However, the total profits will depend on what you spend beyond the cost of flowers and supplies. Generally, the profit margin of flowers is 3 to 4 times their wholesale cost, while the profit margin of hard products is 2 to 2.5 times their cost. The design fee should range between 30 and 50%, depending on the complexity of the design. In addition to flowers and supplies, there are other costs associated with running a florist business, such as rent, telephone, internet, etc.
These costs should be taken into account when calculating your total profits.
