From the grading table to a sales plan
One harvest rarely has one price
Imagine sorting a crop after picking. The best grade has a buyer at one price; the processing grade has another. A second picking may bring a different mix and another quote. If you multiply the whole harvest by the top price, the sales estimate looks better than the crop can actually deliver.
This calculator gives each saleable group its own line. It adds those lines across grades and harvests to estimate gross crop revenue. The large number is the value of the sales you entered, before transport, commissions, production costs, tax or unpaid crop are considered.
How to use the calculator
Choose the unit you actually sell
Set kg, lb, each item or bunch, then enter a three-letter currency code such as USD or PHP. Every line must use that same unit and currency. If one buyer prices by the box and another by weight, convert those offers to one comparable selling unit before entering them.
Match quantities to their prices
Use one line for each harvest and grade. Enter the quantity you expect to sell after grading and handling loss, then the price per selected unit for that group. Add a grade or another harvest when the quantity or price changes. The starting lines are empty so you can use your own figures.
Read the gross value and its pieces
Select Calculate gross sales. The large result adds all line values; the harvest subtotals let you check where it comes from. If you know the field area, open the optional section for revenue per hectare or acre. Enter a price-change percentage only when you want a price-only low and high scenario.
Follow two harvests through the ledger
Suppose a grower expects four sale groups, all priced in USD per kg. The first harvest has 800 kg of Grade A at USD 2.50/kg and 200 kg of Grade B at USD 1.20/kg. The second has 600 kg of Grade A at USD 2.40/kg and 150 kg of Grade B at USD 1.00/kg.
| Harvest and grade | Saleable kg | USD/kg | Gross value |
|---|---|---|---|
| Harvest 1 · Grade A | 800 | 2.50 | USD 2,000 |
| Harvest 1 · Grade B | 200 | 1.20 | USD 240 |
| Harvest 2 · Grade A | 600 | 2.40 | USD 1,440 |
| Harvest 2 · Grade B | 150 | 1.00 | USD 150 |
The first harvest contributes USD 2,240 and the second USD 1,590. Together they produce USD 3,830 gross revenue from 1,750 kg expected to sell. That is a planning value, not a claim that a buyer will take every kilogram.
The arithmetic behind the answer
For each line, multiply only that line's saleable quantity by its matching price. Add the products for the full plan. Because both grades use kilograms in the example, the calculator can also divide total gross revenue by total saleable kilograms to show a weighted selling price.
Line value = saleable quantity × price per selected unit
Gross revenue = sum of all line values
Weighted price = gross revenue ÷ total saleable quantity
In the example, USD 3,830 ÷ 1,750 kg is about USD 2.1886/kg. This is below the top Grade A price because the lower-priced groups still occupy part of the saleable weight. It is a check on the grade mix, not an extra charge or payment.
If those four groups came from 2 ha, the optional area result is USD 3,830 ÷ 2 = USD 1,915/ha. Use the area that produced the entered sale lines and the same harvest period. The calculator does not convert kg to lb or ha to acres when you change a label; review the entered numbers after changing units.
Give uncertain prices room to move
A buyer quote may change between planning and sale. The optional percentage applies the same change to every entered line price, leaving the quantities and grade mix untouched. With the example's USD 3,830 base and a 10% swing, lower prices give USD 3,447; higher prices give USD 4,213.
That range does not account for fewer sellable units, a changed grade split, exchange rates or the chance of a particular price.
What if the grade mix changes instead?
Keep the first harvest at 1,000 kg, but move 100 kg from Grade A at USD 2.50/kg to Grade B at USD 1.20/kg. Gross revenue falls by 100 × (2.50 − 1.20) = USD 130, from USD 3,830 to USD 3,700. Change the two quantities in the sale lines to test that case. A price-only range cannot show it.
If weather or grading changes how much is sellable, edit the quantities and recalculate. The low and high price figures are not a yield forecast.
Keep gross sales separate from profit
Gross revenue answers what the entered sales may be worth. It does not say what the farm keeps. Harvesting, packing, transport, commissions, rent and other costs can still consume a large share. A buyer's quoted price may also differ from the price finally received after deductions.
Before putting the number in a budget
- Confirm that each grade quantity is saleable and counted once.
- Check whether the price is per kg, per lb, per item or per bunch.
- Use the same currency on every line; convert outside this tool if buyers pay in different currencies.
- Record whether a quoted price includes packing, transport or commission.
- Compare the same field and season when using revenue per area.
If you only know a gross field harvest, use the Harvest Loss and Marketable Yield Calculator first. That keeps rejects out of the priced weight. For net returns, transfer the sales estimate to the Farm Profit Calculator and enter the relevant costs there.
