Define it outside the if statement.

double insuranceCost;
if (this.comboBox5.Text == "Third Party Fire and Theft")
        {
          insuranceCost = 1;
        }

If you return it from a method, you can set it to the default value or 0, otherwise you may receive the error message "Using an unassigned variable";

double insuranceCost = 0;

or

double insuranceCost = default(double); // which is 0.0

In addition to the other answers, you can simply insert ifin this case (brackets are added only for clarity):

double insuranceCost = (this.comboBox5.Text == "Third Party Fire and Theft") ? 1 : 0;

Replace with 0any value you want to initialize insuranceCostto if the condition does not match.
