Calorie-per-Dollar

Find the most food energy per dollar from a simple ranked list.

Calories ÷ price, ranked. The most brutal possible measure: how many calories of fuel does each item buy? Not a nutrition plan — a survival-window tool for when the grocery budget is the constraint.

▸ METHODOLOGY
Calories per dollar = calories ÷ price. The tool ranks any list by fuel efficiency — brutal math for the budget floor. It makes no claim about nutrition or health; 2,000 calories of rice is not the same as 2,000 calories of spinach. Use as a survival-window tool, not a meal planner.

How to use

  1. Add items with Name, Price, and Calories (per package).
  2. The tool ranks them by calories per dollar.
  3. Use the best-ranked items as the survival base; layer variety on top if budget permits.

Examples

Rice vs fast food
5lb rice at $6.50 = ~1,230 cal/$. A $12 fast-food combo at 1,100 cal = ~92 cal/$. 13× gap.

Before you trust the result

Check the inputs that matter most: dates, rates, units, costs, and any optional fields you skipped. A calculator can only work with the numbers entered here, so use the result as a decision check rather than a final answer when money, health, tax, legal, or safety consequences are involved.

If the result feels surprising, change one input at a time and watch which number moves. That usually shows the real lever behind the decision.

Frequently asked questions

› Should I eat only the top of the list? Trust & accuracy

No — this is fuel math, not nutrition. Pair highest cal/$ with cheap protein and vegetables for a sustainable base.

› How accurate are calorie labels? How-to

Within ~10%. Good enough for ranking decisions.
