Choose and plan a small farm project
A good first project is small, quick and safe: salad leaves in pots, a vegetable stall, egg sales, or a seed-saving box. Pick one using three tests: Do we have the skill? Can we get the land, water and tools? Will someone buy it?
Then write a one-page plan: goal, who does what, dates, budget and the place of sale (use the Plan-Do-Check cycle).
Budget: fixed and variable cost
Fixed cost stays the same whatever you sell: stall rent, tools, a licence. Variable cost grows with each kilo: seeds, water, packing.
Total cost = fixed cost + variable cost per kilo × kilos.
Example: fixed 600; variable 12 per kilo. For 100 kg total cost = 600 + 12 × 100 = 1800.
Break-even point
The break-even quantity is where income equals total cost.
Break-even kg = fixed cost ÷ (price − variable cost per kg). Here 600 ÷ (20 − 12) = 75 kg. Below 75 kg we lose; above we profit. A higher price or lower unit cost makes break-even come sooner.
Always ask: can we really sell that many kilos? If not, the project needs a change.
Records and the project report
Keep a daily record: date, work done, money spent, kilos sold, money received, and comments. Take photos.
At the end write a short report: 1) goal, 2) plan and budget, 3) what happened (table of income and costs), 4) profit or loss, 5) what we learned and what we will change. Add a simple bar chart. Share it with your teacher or group.
Key formulas and definitions
- Total cost = fixed cost + (variable cost per kg × kg)
- Break-even kg = fixed cost ÷ (price − variable cost per kg)
- Profit = price × kg − total cost
Worked examples
1. Fixed cost 600, variable 12 per kg. Total cost for 50 kg?
600 + 12 × 50 = 600 + 600 = 1200.
2. Price 20. Find break-even kg.
600 ÷ (20 − 12) = 600 ÷ 8 = 75 kg.
3. Sell 100 kg at 20. Profit?
Income 2000. Cost 600 + 1200 = 1800. Profit 200.
4. Price rises to 24. New break-even?
600 ÷ (24 − 12) = 600 ÷ 12 = 50 kg. Break-even comes sooner.
5. Price 15, but fixed cost cut to 300. Break-even?
300 ÷ (15 − 12) = 300 ÷ 3 = 100 kg.
Common mistakes
- Forgetting fixed costs and thinking profit begins at the first kilo.
- Using price instead of (price − unit cost) in the break-even formula.
- Not checking whether the break-even quantity can really be sold.
- Writing a report without numbers or lessons.
