How Much Money Did Initial Sullivan Earn by Selling Re-Bottled 250ml Bottles of Dish Washing Liquid?

Entrepreneurship often involves finding unique ways to make a profit, and Initial Sullivan’s venture into the dishwashing liquid business is a perfect example. Sullivan purchased a 5L bottle of dishwashing liquid, repackaged it into 250ml bottles, and sold each for .00. This article will delve into the details of Sullivan’s business model, including how much money he made from this venture.

Understanding the Business Model

Initial Sullivan’s business model is a classic example of buying in bulk and selling in smaller quantities. He purchased a 5L bottle of dishwashing liquid, which he then divided into smaller 250ml bottles. This approach allowed him to sell the smaller bottles at a higher price per unit volume, thus making a profit.

Calculating the Number of Bottles

To understand how much money Sullivan made, we first need to determine how many 250ml bottles can be filled from a 5L bottle. Since 1L equals 1000ml, a 5L bottle contains 5000ml of liquid. Dividing this by the volume of the smaller bottles (250ml), we find that Sullivan could fill 20 bottles (5000ml ÷ 250ml = 20).

Calculating the Total Earnings

With the number of bottles determined, we can now calculate Sullivan’s total earnings. If each 250ml bottle was sold for .00, then by multiplying the price per bottle by the number of bottles, we find that Sullivan earned a total of 0.00 (20 bottles x .00/bottle = 0.00).

Considering the Cost of Goods Sold

While it might seem that Sullivan made a substantial profit, it’s important to consider the cost of goods sold (COGS). This includes the cost of the 5L bottle of dishwashing liquid and the cost of the 250ml bottles used for repackaging. Without this information, we can’t accurately determine Sullivan’s net profit.


Initial Sullivan’s venture into selling re-bottled dishwashing liquid demonstrates the potential profitability of buying in bulk and selling in smaller quantities. While we can calculate his gross earnings as 0.00, the net profit would depend on his costs. This example underscores the importance of understanding all aspects of a business model, including costs and potential earnings, before embarking on a new venture.
