How to Use the Grow a Garden Value Calculator
This tool estimates the net savings and ROI of growing vegetables at home. All inputs are in imperial units (square feet, pounds, dollars).
- Enter Garden Area (sq ft) – The total size of your garden plot.
- Select Crop Type – Choose from the dropdown (e.g., Tomato, Lettuce). This is for reference; it does not affect calculations.
- Enter Yield per sq ft (lbs) – How many pounds of produce you expect per square foot.
- Enter Local Price per lb ($) – The market price for that vegetable in your area.
- Enter Cost per sq ft ($) – Your expenses (seeds, soil, water, etc.) per square foot.
- Click "Calculate Value" – The form validates inputs and shows results below.
Results explained:
- Total Yield = Area × Yield per sq ft (in lbs)
- Total Value = Total Yield × Price per lb (in $)
- Total Cost = Area × Cost per sq ft (in $)
- Net Savings = Total Value – Total Cost (positive = money saved)
- ROI = (Net Savings / Total Cost) × 100% (percentage return on your investment)
Tip: Use realistic values for yield and cost. Negative net savings mean gardening costs more than buying produce.
