Zarai OS
Land preparation (Zameen ki tayari)
Tractor hours, diesel, laser levelling, deep ploughing, rotavator, and yearly theka if rented.
How it works
From seasonal expenses to your exact per-acre cost
You do not have to do complicated division at harvest. Enter each cost as you spend it, and ZaraiOS organizes it by acre and by maund.
- 1
Enter field size and crop
Enter the field area in acres or kanals (e.g. 5 acres wheat). Ready crop stages help keep entries organized.
- 2
Record expenses as they happen
Log tractor hours, diesel, seed bags, fertiliser (DAP/urea), canal or tube-well water, sprays, and mazdoor wages.
- 3
Enter your harvest yield
At harvest time, enter the total bags or maunds harvested and sold, including deductions and market commission.
- 4
Read your cost per acre and per maund
ZaraiOS divides your total recorded cost by field acreage and by total maunds so you know your break-even price.
Cost categories

How small entries add up to explain your real cost per acre and profit. (Example figures only).
| Expense category | Recorded entries (4 acres) | Cost per acre |
|---|---|---|
| Land prep & theka | Tractor 8 hrs (Rs 24,000) + Half theka (Rs 100,000) | Rs 31,000 / acre |
| Seed & sowing | 4 bags seed (Rs 22,000) + drilling (Rs 8,000) | Rs 7,500 / acre |
| Fertiliser & spray | 4 DAP + 8 Urea + weed spray (Rs 118,000) | Rs 29,500 / acre |
| Tube-well & water | 4 irrigations diesel (Rs 36,000) + waterman (Rs 8,000) | Rs 11,000 / acre |
| Harvest & threshing | Reaper & thresher (Rs 48,000) + bags (Rs 8,000) | Rs 14,000 / acre |
Total: Rs 93,000 per acre. If yield is 40 maunds/acre, cost per maund is Rs 2,325. Figures are examples only: ZaraiOS never assumes rates.
Keep dealer credit, loans and money owed to you in order too. See how the kisan khata works

Cost per acre questions
How does ZaraiOS calculate cost of wheat production per acre?
It sums all expenses recorded for that wheat crop (seed, tractor, fertiliser, water, labour, harvest) and divides the total by your field acreage.
Can I see my cost per maund (per mun)?
Yes. When you enter harvest production, ZaraiOS divides your total crop expenses by the number of maunds produced, showing your exact break-even cost per maund.
How is tube-well diesel divided if one filling waters multiple fields?
You can log the diesel purchase in the Store (Godam) and charge the exact amount used to each crop stage.
How is yearly zameen theka included in cost per acre?
When adding a theka field, choose how many crops it covers (e.g. 2 crops). Half the theka is automatically applied as a land cost to each crop.
Does ZaraiOS publish standard cost per acre figures for Pakistan?
No. Government and university studies publish averages, but every farmer has different soil, tube-well water and tractor rates. ZaraiOS calculates your own real cost.
Can I use it for onion, cotton, maize and vegetables?
Yes. Wheat and onion have ready stage outlines. Any other crop uses custom stages to track cost per acre.
Can I compare this year’s cost per acre with last season?
Yes. Past seasonal reports remain saved on your phone and account so you can compare whether diesel or fertilizer expenses increased.
Does the cost calculator work without internet in the field?
Yes. All expense logging and report calculations work completely offline on Android.
