Crop Yield Calculator
Estimate your total crop production and yield per hectare or acre — either from an average expected yield rate, or from a small sample harvest using the crop-cutting method. Optional revenue estimate included.
Typical Yield Rate by Crop (Reference Chart)
Commonly cited average yield ranges (quintals/hectare) for irrigated, well-managed fields — use these to sanity-check your own estimate.

How the Crop-Cutting Sample Method Works
The same technique agricultural departments use to estimate yield before full harvest.
What Is Crop Yield and Why It Matters
Crop yield is the amount of harvested produce obtained from a given area of land, and it's the single number that ultimately determines how a season's investment in seed, fertilizer, water and labour translates into actual return. In most of India, yield is conventionally measured in quintals per hectare (1 quintal = 100 kg), though tonnes per hectare are also common for bulk crops like sugarcane, and yield per acre remains widely used wherever landholding and leasing is still measured in acres.
Knowing your crop yield — or getting a reliable early estimate of it — matters for far more than curiosity. It informs storage and transport planning, helps negotiate sale contracts or forward pricing, and lets you compare this season's performance against past seasons or against regional averages to spot where inputs, timing, or variety choice might need adjustment next time.
Two Ways to Estimate Yield With This Calculator
Method 1: By Expected Yield Rate
If you already have a reasonable expectation of your yield rate — based on your own historical performance, your variety's typical potential, or a regional average — you can simply enter that rate directly, along with your field area, to get your total expected production.
Method 2: By Sample Harvest (Crop-Cutting Method)
This is the more rigorous approach, and it's the same method used by state agriculture departments to estimate yields across large areas before full harvest. You mark out a small, representative sample plot — commonly 5×5 or 10×10 metres — harvest and weigh the produce from just that plot, and this calculator scales that result up to a full per-hectare and per-acre figure using the formula below.
Yield (kg/ha) = [Sample Weight (kg) ÷ Sample Plot Area (m²)] × 10,000
For example, harvesting 5 kg of grain from a 10m × 10m (100 m²) sample plot scales up to 500 kg/ha, or 5 quintals per hectare, once multiplied by the ratio of one hectare (10,000 m²) to the sample plot's area.
How to Use This Calculator
- Choose your method: an expected yield rate, or a weighed sample harvest.
- For the rate method, optionally select a crop preset for a typical reference yield, or enter your own expected figure directly.
- For the sample method, enter the weight you harvested from your sample plot and the plot's area in square metres.
- Enter your total field area in hectares or acres.
- Optionally enter an expected market price per quintal to see a rough gross revenue estimate.
- Tap "Calculate Yield" to see your yield rate, total production, and (if entered) revenue estimate.
Tips for a More Reliable Sample Harvest Estimate
- Choose an average-looking patch. Avoid sampling from the field's edges, the best-looking corner, or a visibly weak patch — pick an area that looks representative of the field as a whole.
- Take more than one sample if possible. Averaging two or three sample plots from different parts of a large or variable field improves reliability considerably over a single sample.
- Use a consistent, known plot size. A clearly marked 5×5m (25 m²) or 10×10m (100 m²) square is easier to measure accurately than an irregular patch.
- Weigh promptly and consistently. Weigh fresh produce the same way you'll weigh your full harvest (e.g., threshed grain at a similar moisture level) so the comparison stays fair.
Typical Yield Rate for Major Crops
| Crop | Typical Yield (Irrigated) | Common Unit |
|---|---|---|
| Wheat | 32–40 | quintal/ha |
| Rice | 25–32 | quintal/ha |
| Maize | 25–30 | quintal/ha |
| Sugarcane | 70–80 | tonnes/ha |
| Cotton (seed cotton) | 15–18 | quintal/ha |
| Soybean | 12–15 | quintal/ha |
| Groundnut | 15–18 | quintal/ha |
| Mustard | 12–14 | quintal/ha |
| Potato | 200–250 | quintal/ha |
| Chickpea (Gram) | 12–15 | quintal/ha |
Factors That Cause Actual Yield to Differ From Estimates
- Weather during grain fill or maturation. Heat stress, unseasonal rain, or hailstorms close to harvest can noticeably reduce final yield after an earlier estimate was made.
- Pest and disease pressure. An outbreak occurring after a sample was taken can reduce yield across the rest of the field.
- Harvesting and post-harvest losses. Shattering, lodging, spillage, and drying losses between the field and the point of sale or storage can meaningfully reduce the marketable yield below the biological yield estimated in the field.
- Field variability. Uneven soil fertility, drainage, or pest pressure across a large field can make a single sample plot less representative than intended.
Using Yield Data to Improve Next Season
Recording yield every season — whether from a full harvest or a crop-cutting estimate — builds a track record that's far more useful over time than any single season's number. Comparing yield across seasons against what inputs, weather, and variety were used that year helps identify which combinations reliably perform best on your specific soil and climate, turning yield tracking into one of the simplest, lowest-cost tools for improving decisions season over season.
Final Thoughts
Whether you're estimating ahead of harvest with the crop-cutting method or simply projecting production from an expected yield rate, having a quick, reliable number helps with everything from storage planning to sale timing. Recalculate whenever you update your expected yield rate, complete a new sample harvest, or see current market prices shift, and bookmark this page for next season.
Frequently Asked Questions
Crop yield is the quantity of harvested produce obtained from a given area of land, typically expressed in quintals or tonnes per hectare, or in bags or kilograms per acre. It is one of the most important indicators of how well a crop performed in a given season.
The crop-cutting experiment method estimates yield before full harvest by harvesting and weighing produce from a small, representative sample plot, then scaling that result up to a per-hectare or per-acre figure. It is widely used by agricultural departments and researchers to estimate yield across large areas without waiting for the entire harvest.
Accuracy depends heavily on how representative the sample plot is of the whole field. Choosing an average-looking area rather than the best or worst patch, and using a reasonably sized plot such as 5x5 or 10x10 metres, generally produces a more reliable estimate.
One quintal equals 100 kilograms, and one tonne equals 10 quintals, so dividing a yield figure in quintals per hectare by 10 gives the equivalent in tonnes per hectare.
Average irrigated wheat yield in many regions typically falls between 32 and 40 quintals per hectare, though well-managed fields with good varieties and inputs can exceed this, while rainfed or stressed conditions often yield less.
Yes, if you enter an expected price per quintal, this calculator multiplies that by your estimated total production to give a rough gross revenue estimate, before accounting for input costs, transport, or market price fluctuations.
Yield estimates are influenced by weather, pest and disease pressure, soil fertility, water availability, and harvesting losses that occur after any sample is taken, so the final actual yield can reasonably differ from an earlier estimate by a meaningful margin.
Either works — this calculator supports both units and converts automatically. Use whichever unit matches how your land records, lease agreement, or local market typically report the area.
