Static Grading & Price Assumptions
Farm Yield & Revenue Calculator
Illustrative 4:1 assumption for washed/honey drying costs. Replace with your measured conversion. Not used for natural processing.
For yield and revenue estimates, enter your scenario base price. This mode applies the selected grade and region premiums.
Quality Improvement Roadmap
For this quality comparison, enter your scenario base price. The model applies the current and target grade premiums to this amount.
Illustrative starting quantity; enter your measured or planned total output. This total is not multiplied by farm area.
Processing Cost Breakdown
For washed or honey processing, enter your measured cherry-to-parchment weight ratio. The illustrative default is 4:1; natural processing does not use it.
For processing estimates, enter the price per kilogram of green coffee. This mode does not add grade or region premiums.

Frequently Asked Questions
Are these current coffee prices?
No. The built-in USD prices and percentage premiums are static planning assumptions without a verified observation date. They are not a live ICE feed, auction result or offer from a buyer.
Does a grade guarantee a price premium?
No. Grade names and model premiums help compare scenarios, but the calculator does not certify a lot or establish its sale price. Confirm specifications, sampling, cup assessment and commercial terms with the relevant authority and buyer.
How is cherry weight converted?
The model uses its displayed cherry-to-green ratio. Washed and honey drying costs also use an editable cherry-to-parchment ratio, initially 4:1 as an illustrative assumption. These are separate conversions; replace assumptions with measured batch yields.
Is the displayed margin my farm profit?
No. It subtracts modeled processing costs from reference export revenue. Farm production costs, taxes, financing and other unentered costs are excluded. It is not a farm-gate payment or a full farm profit calculation.
Can quality improvement guarantee a higher grade?
No. The comparison applies static grade premiums to an estimated volume. Achieving a grade requires independent assessment, and changes may involve extra costs that this comparison does not calculate.
Where should I verify prices and grading?
Consult dated market information and your buyer’s written terms. The International Coffee Organization publishes market indicators; Kenya’s Agriculture and Food Authority publishes coffee grading information. These sources do not validate the calculator’s built-in numeric assumptions.
Verify the assumptions before making a decision
This calculator uses static grade, yield, price and cost references. A year-only label is not evidence of current market prices. Actual batch weights, buyer terms and costs may differ.
References reviewed on 10 October 2026: ICO public market information and Kenya AFA coffee resources. These describe market information and grading resources; they do not verify the built-in prices, premiums or yields.
Compare scenarios using measured inputs
Check area, tree density, production, conversion ratios and processing costs against farm or mill records. Compare revenue after processing with the excluded production, tax, finance and other costs before assessing farm profitability. A modeled grade premium is not a guaranteed payment.
