Meal Prep Calculator

Nutritional Economics & Batch Culinary Metrology

Meal prepping optimizes both household microeconomics and macronutrient intake:

• **

• Cost per Meal & Savings Formulas**:

$$\text{Cost per Meal} = \frac{\text{Weekly Grocery Prep Cost}}{\text{Meals Prepped per Week}}$$

$$\text{Weekly Savings} = (\text{Meals} \times P_{\text{takeout}}) - \text{Grocery Prep Cost}$$

$$\text{Annual Savings} = \text{Weekly Savings} \times 52$$

• **

• Effective Kitchen Labor Hourly Wage Formula**:

$$\text{Effective Hourly Prep Wage} = \frac{\text{Weekly Financial Savings}}{\text{Weekly Prep Time (Hours)}}$$

• **

• The 10-Year Compound Investment Formula ($8\%$ Return)**:

$$FV = \text{Annual Savings} \times \left[ \frac{^{10} - 1}{r} \right]$$

Double-check your units before entering values — unit errors are the most common source of incorrect results. For critical decisions, cross-reference with at least one additional source or professional consultation.
