Understanding how to calculate the cost per 100g is essential for making informed purchasing decisions and optimizing your grocery budget. This guide provides detailed insights into the formula, practical examples, and frequently asked questions to help you master this skill.

Why Cost Per 100G Matters: Save Money with Smart Shopping Decisions

Essential Background

The cost per 100g helps consumers compare the value of different products regardless of their packaging size or price tag. By calculating this metric, you can:

• Save money: Identify the most cost-effective options
• Optimize budgeting: Allocate funds more efficiently
• Make healthier choices: Compare nutritional content relative to cost

This calculation is particularly useful when comparing bulk purchases, packaged goods, or items sold by weight.

Accurate Cost Per 100G Formula: Simplify Your Shopping Experience

The relationship between cost, weight, and cost per 100g is straightforward:

\[ CP100G = \frac{C}{W} \times 100 \]

Where:

• CP100G is the cost per 100g
• C is the total cost in dollars
• W is the weight in grams

Example: For a product costing $4.50 with a weight of 300g: \[ CP100G = \frac{4.50}{300} \times 100 = 1.50 \, \text{$/100g} \]

Practical Calculation Examples: Empower Your Grocery Shopping

Example 1: Comparing Two Brands of Rice

Scenario: Brand A costs $3.00 for 500g, while Brand B costs $5.00 for 1kg.

1. Calculate Brand A's cost per 100g: \(\frac{3.00}{500} \times 100 = 0.60 \, \text{$/100g}\)
2. Calculate Brand B's cost per 100g: \(\frac{5.00}{1000} \times 100 = 0.50 \, \text{$/100g}\)
3. Conclusion: Brand B is cheaper at $0.50 per 100g compared to Brand A's $0.60.

Example 2: Bulk vs. Packaged Goods

Scenario: A 1kg bag of flour costs $4.00, while a 500g package costs $2.50.

1. Calculate bulk cost per 100g: \(\frac{4.00}{1000} \times 100 = 0.40 \, \text{$/100g}\)
2. Calculate packaged cost per 100g: \(\frac{2.50}{500} \times 100 = 0.50 \, \text{$/100g}\)
3. Conclusion: The bulk option is more economical.
