Inventory Carrying Cost & What Holding Stock Really Costs
Prices the holding of grain
Holding grain, inputs or produce costs money — interest, storage and shrinkage. Enter the value, the three percents and the months stored to get the total carrying cost, the annual rate and the cost per month.
Cost of holding your stock
Next: if the cost of carrying exceeds the price gain you expect from waiting, sell sooner — every idle month at ₹6,250 eats your margin.
Carrying cost bundles the interest on tied-up capital, physical storage and expected spoilage/shrinkage. It is the price of holding rather than selling.

Stored grain is not free — it quietly bleeds value
Holding stock to sell later feels costless, but it is not. The cash locked in the grain cannot work elsewhere, the store charges rent and power, and pests, moisture and spoilage shave the quantity. Together these are the carrying cost — carrying rate (interest + storage + shrinkage) applied to the value and scaled by the months held. It is the hurdle any later price rise must clear before holding pays.
This tool reports the total carrying cost, the annual carrying rate and the cost per month, in your currency, as you type. Use it for every store-or-sell call: if six months of holding costs 12% of value, the later price must beat that to be worth it. Pair it with the Economic Order Quantity, Annuity Future Value and Debt-to-Asset Ratio tools to manage the farm's cash.

Frequently Asked Questions
How is inventory carrying cost calculated?+
First the annual carrying rate is the sum of the interest, storage and shrinkage percents. The cost is then that rate applied to the inventory value, scaled by the fraction of a year held: carrying cost = inventory value × annual rate% × (months ÷ 12). So 500,000 of grain at a 24% annual rate held for 6 months costs 500,000 × 0.24 × 0.5 = 60,000.
What goes into the carrying rate?+
Three components add up to the annual carrying rate: the interest cost of the cash tied up in stock, the storage cost (warehouse rent, handling, electricity, fumigation), and the shrinkage cost (weight loss, spoilage, pests, theft). The tool sums whatever percents you enter for each, so you can include only the ones that apply to your store.
Why does the cash I tie up in stock cost money?+
Money sitting in stored grain or inputs is money you cannot use elsewhere — it could be repaying a loan, earning interest, or funding the next crop. That opportunity cost is captured as the interest component of the carrying rate. Even self-financed stock has this cost, because the cash has an alternative use.
What is shrinkage and how big is it?+
Shrinkage is the stock you lose while holding it — moisture loss, spoilage, rodents and insects, spillage and theft. For grain in a basic store it can run a few percent over a season; for perishables it is far higher. Enter a realistic shrinkage percent and the tool turns it into a money figure, which often surprises people.
How does carrying cost help a store-or-sell decision?+
If you are tempted to hold grain for a higher price later, the carrying cost is the hurdle that price rise must clear. If holding for six months costs you 12% of the value, the later price must be more than 12% higher just to break even. The tool gives you that cost so you can compare it against the expected price gain before deciding to store.
What is the cost per month figure?+
It is the total carrying cost divided by the months stored — the running cost of holding the stock for one more month. It is handy for deciding how long to hold: each extra month adds that amount, so you can see the point where waiting for a better price stops being worth it.
What is a typical annual carrying cost percentage?+
Across interest, storage and shrinkage, total carrying cost commonly lands around 18–25% of inventory value a year, though it varies widely with interest rates, storage quality and how perishable the goods are. Enter your own components rather than a rule of thumb — high interest or poor storage can push it well above that range.
Are the figures exact?+
The maths is exact for the percents and months you enter, but the result is only as good as those estimates — especially shrinkage, which is easy to underestimate. Measure your real storage losses where you can, include the true interest cost of the cash, and re-run the tool to keep your store-or-sell calls grounded.
