Enter the costs ($) and the weight (g) into the Calculator. The calculator will evaluate the Cost Per 100G. 

Cost Per 100G Formula

CP100G = C / W * 100


  • CP100G is the Cost Per 100G ($/100g)
  • C is the costs ($)
  • W is the weight (g)

To calculate the Cost Per 100G, divide the total cost by the weight in grams, then multiply by 100.

How to Calculate Cost Per 100G?

The following steps outline how to calculate the Cost Per 100G.

  1. First, determine the costs ($). 
  2. Next, determine the weight (g). 
  3. Next, gather the formula from above = CP100G = C / W * 100.
  4. Finally, calculate the Cost Per 100G.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

costs ($) = 400

weight (g) = 70


What is the significance of calculating Cost Per 100G?
Calculating Cost Per 100G is crucial for comparing the price efficiency of products sold by weight. It allows consumers and businesses to make informed decisions by evaluating the cost-effectiveness of different items or ingredients, ensuring budget optimization.

Can the Cost Per 100G formula be used for any type of product?
Yes, the Cost Per 100G formula can be applied to any product sold by weight. It is particularly useful for food items, raw materials, and bulk goods where price comparison based on weight is essential for cost management.

How can inaccuracies in calculating Cost Per 100G be avoided?
To avoid inaccuracies, ensure that the weight (W) is correctly measured in grams and the cost (C) is accurately recorded. Use precise scales for weight measurement and double-check the currency and cost input to ensure accurate calculation.

Is it possible to calculate Cost Per 100G for services instead of products?
The Cost Per 100G calculation is specifically designed for tangible products sold by weight. For services, other metrics such as Cost Per Hour or Cost Per Service Unit are more appropriate and relevant for evaluating efficiency and cost-effectiveness.
