How to Use the Food Waste Cost Calculator
Enter your monthly grocery spending, current food waste rate, and target waste rate to instantly see monthly and annual waste losses — plus how much you could save by reaching your target.
US households waste an estimated 30–40% of food purchased, costing the average family of 4 around $1,500–$2,000 per year. Even cutting waste from 30% to 15% saves $750/year — more than a week's groceries.
The USDA suggests meal planning, proper storage, and FIFO fridge organization as the most effective ways to cut food waste below 10%.
