The Free Shelf Life Calculator Built for Real Food Safety
Shelf Life Calculator is a science-backed tool that helps home cooks, restaurants, and food service professionals instantly determine how long food stays fresh — with storage conditions, freshness scores, and expiration dates.
Why We Built Shelf Life Calculator
From frustration with confusing food labels to a tool trusted by thousands — here's how it happened.
Every year, roughly one-third of all food produced globally goes to waste. Households throw away perfectly good food because they're unsure whether it's still safe to eat, relying on confusing "best by", "use by", and "sell by" labels that most people misunderstand.
We watched families toss food that was still perfectly fresh — and eat food that should have been discarded — simply because they had no easy way to check. They deserved a single, science-backed tool that gives clear, instant answers about food freshness.
Shelf Life Calculator was built from the ground up using FDA, USDA FoodKeeper, and peer-reviewed food science data. We mapped real-world storage scenarios — refrigerated, frozen, room temperature, opened vs. sealed — and turned them into an intuitive calculator anyone can use in seconds.
Home cooks, restaurant managers, grocery store staff, food banks, and meal prep enthusiasts rely on Shelf Life Calculator every day to reduce waste, save money, and protect their families from foodborne illness.
Our Mission
We believe everyone deserves a simple, free way to know whether their food is still safe to eat. No one should have to guess — or waste perfectly good food out of uncertainty.
Shelf Life Calculator exists to empower every household, restaurant, food bank, and meal prep enthusiast with accurate, science-backed freshness data — instantly and for free.
Why Food Freshness Matters
Foodborne illness affects 1 in 6 Americans every year. At the same time, the average family wastes $1,500 worth of food annually — often because they can't tell what's still safe.
Shelf Life Calculator bridges this gap by using FDA and USDA data to model real-world storage conditions — temperature, packaging, humidity — so you get answers grounded in food science, not guesswork.
