Eating Out Budget Calculator

Consumer Economics & Food Dining Expenditure Metrology

Dining out costs are calculated by aggregating weekly meals across categories:

• **

• Weekly Dining Out Spending Formula**:

$$\text{Weekly Spend} = (N_{\text{lunch}} \times P_{\text{lunch}}) + (N_{\text{takeout}} \times P_{\text{takeout}} \times N_{\text{people}}) + (N_{\text{dinner}} \times P_{\text{dinner}} \times N_{\text{people}})$$

$$\text{Annual Dining Spend} = \text{Weekly Spend} \times 52$$

$$\text{Monthly Restaurant Budget} = \frac{\text{Annual Spend}}{12}$$

• **

• Home Cooking & Meal Prep Savings Formula**:

• Restaurant meal markup is typically $3.5\times\text{ to }5\times$ the cost of raw grocery ingredients.

$$\text{Annual Meal Prep Savings} = \text{Annual Dining Spend} \times 65\%$$

• **

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

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

• **

• Standard Dining Lifestyle Benchmarks**:
