What is the average cost of 1 teaspoon vanilla?

The average cost of 1 tsp of vanilla extract varies depending on the brand and quantity purchased. A bottle of pure vanilla extract typically contains between 8-16 teaspoons, so the cost per teaspoon would be a fraction of the total bottle price. For example, a 4 oz bottle of pure vanilla extract may cost around $10, which would make the cost per teaspoon about 60-130 cents.
