Yield Gap Calculator
Compare your actual yield with the achievable potential to quantify the yield gap.
The yield gap is the difference between what you get and what the best farmers (or research plots) achieve in your area. Closing it — through better varieties, nutrition, water and pest management — is usually cheaper than bringing new land into production.
Indicative planning figures based on published research averages. Local soil tests, varieties and weather change actual requirements — confirm with your agronomist or extension officer.
Farmers and agronomists use the free Yield Gap Calculator for an accurate answer in seconds — no formulas to remember, works offline.
About Yield Gap Calculator
The yield gap is the distance between the yield you currently get and the yield that the best farmers — or research stations — achieve in the same area with the same crop. Quantifying it shows how much upside is realistically on the table from better management, before any thought of new land or major investment. Enter your actual yield and the achievable potential, and this tool reports the gap in quintals per hectare and as a percentage, plus how much of the potential you're already capturing.

Frequently asked questions
What is a yield gap?+
It is the difference between your actual yield and the achievable potential yield for your crop and area (the yield top farmers or trials reach). A large gap means significant yield is being lost to management, inputs or stress that could be addressed.
How do I close a yield gap?+
Usually by improving the most limiting factor first — soil fertility, balanced nutrition, timely irrigation, a better variety, or pest and weed control. Closing the gap on existing land is typically cheaper and faster than expanding area.
Is this tool free and private?+
Yes — free, no sign-up, and all calculation runs in your browser, so it works offline and your data never leaves the device.
