Scratch vs Boxed Cost Comparer
Scratch vs Boxed Cost Calculator
What this calculator does
Boxed mixes are convenient but often cost more per serving than making food from scratch.
The math, with a worked example
Boxed per serving = box cost ÷ servings. Scratch per serving = flour cost ÷ uses + egg cost ÷ eggs per carton. A $3 box with 10 servings costs $0.30 per serving. $5 flour over 10 uses plus $4 eggs over 12 costs about $0.83 per serving. Adjust ingredients to match your recipe.
Why this matters
Boxed mixes sell convenience, but the price gap is testable: $0.30 a serving boxed against about $0.83 from scratch in the worked example — scratch loses that round. The point isn't that either always wins; it's that a 2-minute division beats the assumption.
Methodology and transparency
Boxed = box price ÷ servings; scratch = flour price ÷ uses per bag + egg price ÷ eggs per carton. The scratch side counts only the ingredients you list, and that's the assumption to challenge: leave out butter, sugar, or milk and scratch looks cheaper than it cooks. Add every real ingredient's per-use cost before calling a winner. Everything runs in your browser; no data is sent or stored.
