Gardening Crop Yield & Cost Calculator
Calculate crop yields, produce value, setup costs, and net grocery savings of cultivating home vegetables in a garden versus buying them.
Gardening Yield & Cost Formulas
The economic return of a home garden is calculated by comparing the store value of the harvest against the upfront setup costs, seeds, water, and fertilizers.
Average yields per plant: Tomatoes: 20 lbs; Cherry Tomatoes: 3 lbs; Zucchini: 6 lbs; Bell Peppers: 7 lbs; Lettuce: 1.5 lbs.
How to Calculate Gardening Savings

Add your crops to the tracker
Configure up to three crops, defining the plant count, average expected yield per plant, and regional retail price.
Evaluate your total harvest value
The calculator will compute the total weight and market value of all crops combined.

Real-World Scenario Example
"A gardener spends $100 on raised beds and $40 on water/soil. They plant 5 tomatoes (yielding 20 lbs each, priced at $3.00/lb) and 10 lettuce plants (yielding 1.5 lbs each, priced at $2.50/lb)."
Inputs
Result
Yield of 115 lbs of produce with a grocery store value of $337.50. After subtracting the $140 total investment, the net savings are $197.50, representing an ROI of 141.1%.
Important Disclaimer
Agricultural yields are highly dependent on local soil health, weather patterns, pest controls, and direct care. Calculations are estimates and do not guarantee crop yields.
