What this calculator does
The Vegetable Yield Calculator estimates your total expected harvest weight for a home garden crop, based on typical average per-plant yield figures reported by university extension gardening guides.
How the formula works
The calculation is straightforward: total yield = number of plants × average yield per plant, using commonly cited average yields per healthy, mature plant under typical home-garden conditions over a full growing season.
- Indeterminate tomato plants can average around 8-15 lb of fruit per plant in a good season
- Root crops like carrots yield much less per plant but are typically grown at much higher density
A note on accuracy
Actual yields vary widely with variety, soil fertility, watering, pest pressure, climate, and growing season length — treat this as a rough planning estimate for how much to plant, not a guaranteed harvest prediction.
