Adult equivalents = 2(1.0) + 1(0.7) + 1(0.5) = 4.2. Home meals = 3 x 7 - 2 = 19/week. Home cost = 4.2 x $5 x 19 = $399. Eating out = 4.2 x $12.50 x 2 = $105. Wait, let me recalculate: home = $399, out = $105. Total = ~$294 (the calculator uses 2.5x multiplier for eating out cost).

Q
How do age-based portion multipliers work?
Children eat less than adults, so a toddler (1-3) costs about 0.5x an adult portion, a child (4-8) about 0.7x, a pre-teen (9-12) about 0.9x, and teens (13-17) about 1.2x due to growth spurts. A family of 2 adults, 1 toddler, and 1 child equals 3.2 adult-equivalents.
Toddler (1-3 years): 0.5x adult portion
Child (4-8 years): 0.7x adult portion
Pre-teen (9-12 years): 0.9x adult portion
Teenager (13-17 years): 1.2x adult portion
Adult (18+): 1.0x base portion

Q
How much does eating out cost vs. cooking at home?
Eating out costs 2.5-3x more than cooking at home on average. A home-cooked meal costs $3-$8 per adult portion, while a restaurant meal averages $12-$20. For a family of 4, cooking dinner saves $30-$50 per meal compared to dining out. Reducing dining out by 2 meals/week saves $250-$400/month.
Home-cooked meal: $3-$8 per adult portion
Fast food: $8-$12 per adult portion
Casual restaurant: $12-$20 per adult portion
Family of 4 dinner at home: $15-$30 total
Family of 4 dinner out: $50-$80+ total
Q
How can I reduce my family grocery bill?
The top strategies are meal planning (saves 20-30%), buying seasonal produce (saves 15-25%), using store brands (saves 25-30%), buying in bulk for staples (saves 10-20%), and reducing food waste by planning leftovers. A family of 4 can save $100-$200/month by combining these strategies.
Meal planning: Saves 20-30% by reducing impulse buys
Store brands: 25-30% cheaper than name brands
Buy seasonal produce: 15-25% savings
Bulk staples (rice, pasta, beans): 10-20% savings
