Vegetable Yield Calculator

The figures represent realistic garden averages under decent conditions. University extension trial data and community garden surveys inform the baselines. Your actual yield may be higher or lower depending on variety, climate, season length, and specific growing conditions. Use the numbers as planning guides - they are most useful for comparing crops and estimating relative value, not as precise yield guarantees.

Only if you can use that much of it. Zucchini is famous for overproducing - a single plant can supply more than most households need. Choose crops your household will actually eat, then check the yield and value figures to decide how much bed space to allocate. Variety selection within a crop also matters; a paste tomato variety may produce fewer pounds but deliver more usable product per pound than a juicy slicing type.

Use the total planted area, not the path around it. A 4 ft × 8 ft raised bed is 32 sq ft. An in-ground row that is 20 ft long and about 18 inches wide is roughly 30 sq ft. For irregular or mixed plantings, estimate the area each crop actually occupies rather than dividing the whole bed evenly.

Use the current store price for the same quality you expect to grow - if you grow organically or select heirloom varieties, compare to organic store prices, which are often 40-80% higher than conventional prices. Also factor in that home-grown produce at peak ripeness has higher nutritional density and flavor quality than store produce, which may have been harvested days or weeks earlier.
