Meal Prep Efficiency Calculator

Calculate the time and cost savings of meal prepping compared to daily cooking. This calculator helps you optimize your meal preparation schedule and grocery budget while considering factors like ingredient costs, preparation time, and storage efficiency.

How It Works

The calculator uses these formulas to estimate savings and efficiency:

$\text{Time Savings} = (T_d \times D) - (T_p + T_r)$

$\text{Cost Savings} = (C_d \times D) - (C_b + C_s)$

$\text{Efficiency Score} = \frac{\text{Time Savings} + \text{Cost Savings}}{\text{Total Meals}} \times 100$

Where:

• $T_d$ = Daily cooking time per meal
• $D$ = Number of days/meals
• $T_p$ = Batch preparation time
• $T_r$ = Reheating time per meal
• $C_d$ = Daily meal cost
• $C_b$ = Bulk ingredient cost
• $C_s$ = Storage container cost
• Total Meals = Number of meals prepared
