The cocoa farmgate revenue calculator turns a sack of dry beans into the money that lands in your hand after grade, moisture, and buyer deductions. It answers the gap that surprises many growers: the headline price per kilogram is not what you receive. Quality discounts, moisture penalties, and buyer commissions all shave the total, and this tool shows the net revenue and the effective price you truly earn per kilogram.
Loading calculator...
A buyer quotes a price for clean, well-fermented, properly dried beans at target moisture. Real sacks rarely match that ideal exactly. Beans that are under-fermented, too wet, or full of defects get downgraded, and the deduction comes off the whole sack. A farmer who plans income on the quoted price consistently over-budgets.
This calculator applies each deduction in turn to reveal the net revenue and the effective per-kilogram price, so you can see which discount is costing the most and where better drying or fermentation would pay back. It is the difference between the price you were promised and the price you were paid.
π± How to use the cocoa farmgate revenue calculator
Enter the dry bean weight, the mass you are selling at target moisture. The default of 100 kilograms gives a clean read, and the whole revenue scales from it.
Set the farmgate price per kilogram, the quoted base price for standard-grade beans. This is the headline figure, and the deductions that follow explain why your net differs from it.
Choose the quality grade. A premium, well-fermented grade earns the full price or a bonus, while lower grades take a discount for defects, slaty beans, or off-flavors. The grade applies a percentage adjustment to the base.
Ask the buyer exactly how grade is assessed before you sell. A cut test showing 5 percent more brown beans can move you up a grade and recover more than any haggling over the base price.
Set the moisture deduction, the penalty when beans sit above target moisture. Buyers deduct because wet beans weigh more and risk mold, so a batch above 8 percent moisture loses both weight allowance and price. Enter zero if your beans are at target.
Enter the buyer commission, the share a middleman or cooperative takes, and select the currency so the figures display in the money you deal in. Watch the net revenue and effective price tiles fall as each deduction stacks up.
π± Calculator fields explained
Dry bean weight (kg) – Mass of beans sold at target moisture. Default 100 kg. Scales revenue.

π± Understanding the results
| Result | What it means | What it drives |
|---|---|---|
| Gross revenue | Weight times base price, before deductions | The headline figure |
| Quality adjustment | Bonus or discount from grade | Value of quality |
| Net revenue | What you actually receive | Real income |
| Effective price per kg | Net revenue divided by weight | True price earned |
| Deductions total | Sum of grade, moisture, commission cuts | Where value is lost |
The hero number is the net revenue, the money after every deduction. With 100 kilograms at a base of 2.5, a standard grade, no moisture penalty, and a 5 percent commission, gross is 250 and net is about 237.5 in the display currency.
Gross revenue is the seductive figure, the one a buyer quotes and a farmer remembers. The deductions total sitting beside it is the reality check, showing how much of that gross never reaches you.
The effective price per kilogram is the most useful single number, because it lets you compare buyers and batches on equal footing. A buyer with a higher base price but a heavier commission can pay a lower effective price than a lower-base buyer who deducts less.
A high quoted price with steep grade and commission deductions can pay less than a modest quote with none. Judge every offer by the effective price, not the headline.
The quality adjustment quantifies what fermentation and drying are worth. When a low grade knocks 15 percent off, that percentage is the payoff waiting for better processing, and it often dwarfs any gain from arguing the base price.
Grade and commission can erase 20 percent of the quoted price.
Read the extremes: a large moisture deduction signals beans sold too wet, costing twice through weight risk and price, and points straight back to the drying step.
π± Calculation formulas
Revenue starts gross, then applies grade, moisture, and commission in sequence. Illustrative forms follow.
Gross revenue = dry weight x base price
Grade-adjusted = gross x (1 + grade factor)
After moisture = grade-adjusted x (1 - moisture deduction)
Net revenue = after moisture x (1 - commission)
Effective price = net revenue / dry weight
Worked with defaults: 100 kilograms times a base of 2.5 gives 250 gross. A standard grade factor of 0 leaves 250. No moisture penalty keeps 250. A 5 percent commission removes 12.5, leaving 237.5 net, an effective price of 2.375 per kilogram. Switch to a low grade at minus 15 percent and moisture at 5 percent, and net falls to about 190, an effective price near 1.90.
Deductions compound rather than simply add. A 15 percent grade cut followed by a 5 percent commission is not a 20 percent loss but slightly less, because each acts on the reduced figure in turn.
The reconstructed grade factors and parameters follow. Correct them here after checking the code.
| Parameter (verify against code) | Illustrative value | Used for |
|---|---|---|
| Premium grade factor | +10% | Bonus |
| Standard grade factor | 0% | Base |
| Low grade factor | -15% | Discount |
| Moisture penalty per point over target | ~1.5% | Wet deduction |
| Default commission | 5% | Middleman cut |
| Target moisture | 7% | Penalty baseline |
π± Practical examples
Each uses valid inputs and the formulas above; currency is illustrative.
Home grower, small sale. Inputs: 5 kg, 2.5 base, standard, 0 moisture, 0 commission (direct sale). Net 12.5, effective 2.5. Selling direct to a chocolate maker, the grower keeps the full price.
Backyard batch to a co-op. Inputs: 20 kg, 2.5, standard, 0, 5 percent. Net 47.5, effective 2.375. The small commission is the cost of the co-op handling the sale.
Smallholder, premium grade. Inputs: 100 kg, 2.5, premium, 0, 5 percent. Grade adds 10 percent, so net about 261, effective 2.61. Careful fermentation earns more than the base price.
Smallholder, wet beans. Inputs: 100 kg, 2.5, standard, 6 percent moisture deduction, 5 percent. Net about 223, effective 2.23. The moisture penalty costs real money and points back to drying.
The buyer pays for what is in the sack, not what you meant to put there. Every point of moisture and every slaty bean shows up in the effective price.
Low-grade batch. Inputs: 100 kg, 2.5, low, 3 percent moisture, 5 percent. Net about 196, effective 1.96. A low grade plus wet beans drops the effective price to 1.96. The farmer prioritizes fermentation next season.
Commercial lot, premium. Inputs: 1,000 kg, 2.5, premium, 0, 4 percent. Net about 2,640, effective 2.64. The operator’s quality program pays off at scale.
Comparing two buyers. Buyer A: 100 kg, 2.7 base, standard, 0, 10 percent commission gives net 243, effective 2.43. Buyer B: 2.5 base, 0 commission gives net 250, effective 2.50. The lower headline buyer pays more, and the farmer chooses B.
Edge case, rejected-then-resold. Inputs: 100 kg, first buyer rejects for high moisture; after re-drying, 95 kg (weight lost to drying) at 2.5, standard, 0, 5 percent. Net about 226, effective 2.38 on the reduced weight. The re-dry saved the sale but cost weight, so the grower logs the true lesson: dry right the first time.
π± Tips and best practices
Compare buyers on effective price, never on the quoted base. A middleman waving a high headline can still pay less once commission and grading bite, and only the effective price makes the offers comparable. Run each through the calculator before you commit a sack.
Chase grade before you chase price. A single grade step often moves the effective price more than any base-price negotiation, and grade is something your fermentation and drying control, unlike the market. The quality adjustment line shows exactly what that step is worth.
Meet target moisture to avoid the double loss of a moisture penalty on beans that also weigh less once properly dried. Selling wet to save a drying day is usually a false economy the deduction exposes.
Keep a sale log of grade, moisture, deductions, and effective price by buyer. Over a season it shows which buyer and which processing habit actually pays best.
Understand your buyer’s grading standard and ask for the cut-test basis, because knowing the rule lets you hit it. Sell in target-moisture, clean, well-fermented lots that qualify for the top grade you can reach. Consider group or cooperative selling to lift bargaining power even after commission, and time sales to price windows where you can, since the base price you start from still sets the ceiling on everything else.
β οΈ Common mistakes to avoid
Budgeting on the quoted price
Planning household or farm spending on the headline base price ignores the deductions that always follow.
A budget built on the quoted price is short before the beans even leave the farm, because grade, moisture, and commission are already waiting to take their cut.
Plan on the net revenue and effective price instead.
Chasing the highest headline
Choosing the buyer with the biggest quoted price without checking commission can leave you worse off.
The loudest price is not the largest payment. A heavy commission behind a high quote quietly beats you down below a modest, clean offer.
Compare on effective price every time.
Selling beans too wet
Rushing to sell above target moisture triggers a penalty and risks rejection. A moisture penalty can cost more than a day of extra drying saves.
Dry to target before you sell.
Neglecting fermentation quality
Under-fermented, slaty beans drop a grade and take a discount off the whole sack. Ferment fully to reach the grade the price rewards.
Not understanding the grading rule
Selling blind to how the buyer grades means you cannot target the standard. Ask for the cut-test basis and aim for it.
Ignoring commission structure
Overlooking how a co-op or middleman charges hides part of the deduction. Enter the real commission so the effective price is honest.
π± When to use this calculator
Use it whenever you are about to sell and want to compare offers or know your true income. The effective price turns competing quotes with different commissions and grading into a single comparable number, which is the only fair basis for choosing a buyer.
It also helps when you decide whether a processing improvement is worth the effort. Seeing what a grade step or a moisture fix adds to the effective price tells you whether better drying or fermentation pays for itself.
The scale and the grade sheet settle the argument. Know what they will say before you load the sacks.
It is not worth opening for a direct sale at an agreed flat price with no deductions. And it computes the payment mechanics, not the market price itself, so it will not tell you where prices are headed, only what today’s offer really pays. Pair it with the farm ROI tool to feed net revenue into the bigger picture.

β Frequently asked questions
Why do I get less than the quoted price?
Because the quote is for ideal standard-grade beans at target moisture, and deductions for grade, moisture, and commission come off before payment.
The effective price output shows exactly what you net, which is the figure to plan around, not the headline.
How is quality grade decided?
Usually by a cut test that counts well-fermented brown beans against slaty and defective ones, plus checks for mold and foreign matter.
Because grade applies to the whole sack, a small share of poor beans can pull the entire lot down a grade, so uniformity matters.
Ask your buyer for the exact grading basis so you can target it.
How much does moisture cost me?
Selling above target moisture triggers a penalty and, in the worst case, rejection until you re-dry.
Re-drying then costs weight too, so the moisture penalty usually costs more than the drying day it seemed to save.
How do I compare two buyers fairly?
Run each offer through the calculator and compare the effective price per kilogram, not the quoted base.
A higher base with a heavy commission can pay less than a lower base with none, and only the effective price reveals it.
Is a premium grade worth the extra work?
Often yes, because a grade bonus can add more to the effective price than any base-price negotiation.
The quality adjustment line quantifies it, so you can weigh the fermentation and drying effort against the reward.
Does selling through a cooperative pay better?
It can, if the co-op’s bargaining power lifts the base or grade enough to outweigh its commission.
Enter the co-op commission and compare the effective price against selling directly to see which wins for your lot.
Can I avoid commission entirely?
Selling directly to a processor or exporter can, but it requires access, volume, and often meeting quality standards yourself.
For many smallholders a middleman or co-op is the practical route, so the goal is to minimize the effective cost, not eliminate it.
What single change lifts my revenue most?
Usually improving fermentation and drying to reach a higher grade at target moisture, because that removes the two biggest deductions.
Those steps are within your control, unlike the market price, so they are where effort reliably pays back.
