paddy calculator

What this paddy calculator helps you decide

Most growers know their field yield, but fewer convert that number into a true business estimate. A paddy calculator bridges that gap. It turns agronomic inputs into practical outputs: how much marketable paddy you have after drying, how much milled rice that could produce, and what your likely margin looks like after costs.

This matters because two fields with the same wet harvest weight can produce different profits if moisture levels, recovery rates, or sale prices differ. If you sell without moisture correction, you may overestimate revenue. If you ignore milling recovery, you may misjudge downstream value.

Input fields explained

1) Land area and yield

Enter your cultivated area in acres and the average harvested paddy yield per acre. These two values determine your initial gross harvested weight.

• Gross harvested paddy (kg) = Area × Yield per acre
• Use realistic yield averages, not only best-plot numbers

2) Moisture at harvest and target moisture

Paddy is usually harvested at higher moisture and then dried. Weight reduces as water is removed, so using fresh weight as sale weight can be misleading. The calculator applies standard dry-matter correction so your adjusted paddy reflects storage/sale moisture.

3) Milling recovery

Milling recovery is the percentage of paddy that becomes milled rice. This varies with variety, harvest timing, drying quality, and milling efficiency. Typical values might range from 62% to 70% depending on system and quality management.

4) Price and cost

Sale price per kilogram and production cost per acre convert physical output into financial outcomes. This gives quick visibility into gross revenue, break-even price, and net profit.

How the calculator computes results

• Gross harvested paddy: Area × Yield per acre
• Adjusted paddy (after drying): Gross paddy × (100 - Harvest Moisture) / (100 - Target Moisture)
• Drying weight loss: Gross harvested paddy - Adjusted paddy
• Estimated milled rice: Adjusted paddy × Milling recovery
• Gross revenue: Adjusted paddy × Paddy price
• Total production cost: Area × Cost per acre
• Net profit: Gross revenue - Total cost
• Break-even paddy price: Total cost ÷ Adjusted paddy

Worked example

Suppose you farm 5 acres, harvest 2,600 kg/acre at 22% moisture, dry to 14%, get 67% milling recovery, sell paddy at 0.30 per kg, and spend 420 per acre in total production cost.

• Gross harvested paddy = 13,000 kg
• Adjusted paddy after drying ≈ 11,790.70 kg
• Estimated milled rice ≈ 7,899.77 kg
• Gross revenue ≈ 3,537.21
• Total production cost = 2,100.00
• Net profit ≈ 1,437.21

That single adjustment for moisture can significantly change expected revenue and inventory plans.

Practical ways to improve paddy profitability

Reduce post-harvest losses

Poor drying and handling can lower quality, reduce milling recovery, and force discount pricing. Even small improvements in cleaning, drying uniformity, and storage can increase net returns.

Track cost categories clearly

Split your cost per acre into seed, fertilizer, labor, machinery, irrigation, and finance cost. This makes it easier to see what is controllable and where optimization gives the fastest impact.

Plan sales using break-even price

Your break-even price is your safety threshold. If market price is near break-even, consider timing sales, improving quality grade, or reducing avoidable costs before the next season.

Common mistakes this tool helps avoid

• Using wet harvest weight as final sale weight
• Ignoring moisture correction when comparing seasons
• Estimating rice output without recovery percentage
• Assuming positive cash flow means true profit
• Missing break-even analysis before planting decisions

Final note

This paddy calculator is best used as a fast planning tool. For operational decisions, combine it with local price trends, field-level records, moisture meter readings, and actual milling reports. Small improvements in measurement discipline often deliver outsized financial gains over multiple seasons.
