Crop Yield Estimator Calculator Guide
Use this crop yield estimator to project harvest weight from plant count and crop type. Select tomatoes, peppers, cucumbers, lettuce, carrots, or bush beans and enter how many plants you are growing to see a low-to-high yield range in pounds.
How to use the crop yield estimator
Enter the number of plants you plan to grow and select the crop type. The calculator multiplies plant count by published low and high per-plant yield estimates.
Results show a range in pounds — actual harvest depends on variety, weather, fertility, and pest pressure.
Crop yield formula
Low yield (lbs) = Plant count × Low lbs per plant. High yield (lbs) = Plant count × High lbs per plant. Per-plant ranges are preset by crop based on typical home garden performance.
- Tomatoes: 8–15 lbs per plant
- Peppers: 3–5 lbs per plant
- Cucumbers: 10–20 lbs per plant
- Lettuce: 0.5–1 lb per plant
- Carrots: 1–1.5 lbs per plant
- Bush beans: 0.5–1 lb per plant
Worked example
Ten tomato plants at typical home garden yields of 8–15 lbs each.
Estimated harvest = 10 × 8 to 10 × 15 = 80 to 150 pounds of tomatoes over the season.
Factors that shift yield
Indeterminate tomatoes outyield determinates on a per-plant basis given long seasons. Drought, blossom-end rot, and pest damage pull results toward the low end. Trellising, drip irrigation, and balanced fertility push toward the high end.
Using yield estimates in planning
Compare projected harvest to household consumption and preservation plans — 150 lbs of tomatoes supports heavy fresh eating plus canning. Pair with plant spacing and square foot gardening calculators to size beds before ordering seed.
- Record actual weights each season to calibrate expectations.
- Plan succession plantings for crops with short harvest windows.
- Use harvest date calculator for timing preservation batches.
- Diversify crops — do not rely on a single high-yield plant for all produce.
