One click, no sign-up.
Enter how many beds you have and their size, the yield you expect from each square metre or square foot, the price you sell at and how much of the harvest you sell. This shows the harvest and the income.
Yield per square metre depends hugely on the crop, the soil, the weather and your experience, so this tool does not guess it for you. Use a figure from your own records, a seed supplier, or your local extension service. Try a cautious one and a hopeful one to see the range.
How it’s worked out
- Growing area is the number of beds times the length times the width.
- Harvest is the area times the yield per square metre (or square foot).
- Sold is the harvest times the share you sell. The rest is what you keep or lose.
- Income is the amount sold times the price. Per week is the income divided by the weeks you sell.
4 beds of 3 m by 1.2 m make 14.4 square metres. At 3 kg per square metre that is 43.2 kg. Selling 75% at $4 a kg brings in about $130, and over 20 weeks that is about $6.50 a week.
Common mistakes
- Counting the paths. Only the bed itself grows the crop, so measure the beds, not the whole plot.
- Assuming you sell everything. Some is eaten, some spoils, and some does not sell, so put in a realistic share.
- Using a supermarket price. Market and farm gate prices can be higher or lower, so use what people really pay near you.
- Using one crop's yield for a mixed bed. Work out each crop separately and add them up.
Questions
What yield should I put in?
Use your own records if you have them. Otherwise look at a seed supplier's notes or your local extension service for the crop. Yields vary a lot between crops and growers, so use a cautious number first.
Does it include my costs?
No, only the income. To see the profit, use the start-up cost calculator or the farm cost and break-even calculator.
Can I use it without beds?
Yes. Put in 1 bed and type the whole growing area as the length and width, for example 10 by 5.
Does it work in square feet?
Yes. Choose imperial and it uses feet, pounds and square feet.
