Grain Storage Loss Calculator
Estimate the quantity and value of grain lost in storage from a loss percentage.
Post-harvest storage losses (insects, rodents, mould, spillage) commonly run 5–10% in traditional storage and can be cut to 1–2% with dry grain, hermetic bags or metal bins. This shows what the loss is costing you — often more than the cost of better storage.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.

About Grain Storage Loss Calculator
Post-harvest storage losses are a silent tax on farming — commonly 5–10% of stored grain lost to insects, rodents, mould and spillage in traditional storage. This tool puts a number and a rupee value on that loss, and shows what halving it would save. Seeing the cost usually makes the case for improved storage (proper drying, hermetic bags, metal bins or godown hygiene), which can cut losses to 1–2% and pay for itself in a season.

Frequently asked questions
How much grain is lost in storage?+
Traditional on-farm storage commonly loses 5–10% to insects, rodents, mould and spillage; improved storage (dry grain in hermetic bags or metal bins) cuts this to 1–2%. This tool quantifies the loss and its value for your quantity and price.
How can I reduce grain storage losses?+
Dry grain to its safe moisture, store in clean, sealed containers (hermetic bags or metal bins starve insects of oxygen), keep the store rodent-proof and hygienic, stack on dunnage off the floor, and monitor for heating and pests. These steps routinely cut losses from ~8% to ~1–2%.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline at the store/godown and your data never leaves the device.
