Start / Grain and storage / Grain grading and drying
See whether it is worth storing the grain, and up to what future price storage pays off, considering interest, storage and shrinkage.
Pre-sizing and estimating tool: the results do not replace a design, calculation, or report signed by a qualified professional, nor verification against the applicable standards.
How much each item adds or subtracts from the result per bag.
Result per bag if the sale happens between 1 and 12 months, with the future price you entered; the dot is your term.
Drag the controls to simulate data different from what you entered (from 30% less to 30% more) and watch the result change instantly.
Result per bag, in reais, for future prices from 0% to 20% above today's price and different storage terms.
The calculation done in steps, with the values you entered.
The calculation memo gathers this page's inputs, results, equations, assumptions, and references, with fields for project, responsible person, and review. The full report also includes the charts and interpretations, in color. In the print window, choose Save as PDF.
Enter today's bag price, the price you expect on the sale date, the storage time, the monthly storage cost, the monthly cost of capital, and the period's weight loss. The calculator shows the result per bag and the minimum future price to break even.
Soybean at R$ 120/bag today, R$ 130/bag in 4 months, storage at R$ 1.50/bag/month, interest of 1% per month and shrinkage of 0.5%.
Variation = 10.00. Storage = 1.50 × 4 = 6.00. Interest = 120 × 1% × 4 = 4.80. Shrinkage = 130 × 0.5% = 0.65. Result = 10 − 6 − 4.80 − 0.65 = −R$ 1.45/sc, not worth it.
Minimum price = (120 × 1.04 + 6) ÷ 0.995 = R$ 131.46/sc.
Because storing costs money: the storage itself, the interest on idle money, and grain breakage. The future price must cover all of this for you to come out ahead.
Use a market reference (exchange or futures quote for your local market) or a projection from your consultant. The calculator does not forecast prices.
Compare the storage cost per bag of each option, including freight to the warehouse. The calculator uses a single value, which you fill in with the cost of each case.
No. It is a comparison calculation. The decision to sell depends on your cash position, price risk, and commercial strategy.
