How this was calculated
  1. Total potatoes = 100 (100 sacks × 50 kg = 5,000 kg)
  2. All-in cost = buying ৳50,000 + rent ৳30,000 + transport ৳8,000 = ৳88,000
  3. Net potatoes = 5,000 × (1 − 7.5%) = 4,625 kg
  4. Break-even = ৳88,000 ÷ 4,625 = ৳19.03/kg
  5. Profit/loss = 4,625 × ৳35 − ৳88,000 = ৳1,61,875 − ৳88,000 = ৳73,875

How to use

  1. Enter the potato quantity — in sacks (50 kg sacks) or straight in kg.
  2. Type the current buying price and the price you hope to sell at, per kg.
  3. Adjust the rent and transport if yours differ; keep the loss slider between 5–10%.
  4. If the expected price is below break-even you will see a loss warning — remember the lesson of the 2025-26 season.

The formula

Break-even price = all-in cost ÷ net kg after loss

  • Total potatoes (kg) = number of sacks × 50
  • All-in cost = buying (kg × buying price) + rent (kg × rent) + transport (sacks × per-sack charge)
  • Net potatoes = total kg × (1 − loss%)
  • Profit/loss = net kg × expected price − all-in cost

Worked example: a profit

100 sacks bought at Tk 10/kg and sold at Tk 35 — what is the profit?

  • Total = 100 × 50 = 5,000 kg
  • All-in = buying 50,000 + rent (5,000 × 6) 30,000 + transport (100 × 80) 8,000 = Tk 88,000
  • Net = 5,000 × (1 − 7.5%) = 4,625 kg
  • Break-even = 88,000 ÷ 4,625 = Tk 19.03/kg
  • Sale = 4,625 × 35 = 161,875; net profit = Tk 73,875

Worked example: a loss (the 2025-26 lesson)

100 sacks bought at Tk 18/kg but forced to sell at Tk 10?

In 2025-26 harvest prices were high, yet the sale price collapsed to Tk 9–10 — while the all-in cost worked out near Tk 28/kg.

  • All-in = buying 90,000 + rent (5,000 × 6.75) 33,750 + transport 8,000 = Tk 131,750
  • Net = 5,000 × (1 − 10%) = 4,500 kg
  • Break-even = 131,750 ÷ 4,500 = Tk 29.28/kg
  • Sale = 4,500 × 10 = 45,000; net loss = Tk 86,750

So always work out break-even before storing — if the expected price is below it, better not to store.

What to know in Bangladesh

  • Rent is a seasonal flat rate: charged once per kg, not divided by the months stored.
  • 50 kg sacks are mandatory (since 2025). 50 × Tk 6 = Tk 300 rent per sack.
  • Season: in during February–March, out during October–November; ownership transfer by 15 November.
  • Current rates apply till 31 Dec 2026 (DAM notification, 31 Aug 2026). Rates may change after expiry.
  • The normal spread: Tk 8–11/kg at harvest vs Tk 35–40 off-season — that gap is the profit, but as 2025-26 showed, it can reverse.

Rent timeline

2 Mar 2025 (government cap) Tk 6.75
Aug 2026 (owners’ claimed cost) Tk 9.52–9.62

In detail: when storing pays off

Storing potatoes is a bet on the future price. At harvest (February–March) the market is flooded and prices fall to Tk 8–11. Off-season (October–November) supply thins and prices rise to Tk 35–40. After subtracting rent (Tk 6), transport (Tk 65–100 a sack, i.e. Tk 1.30–2 per kg) and shrinkage (5–10%), a profit remains — that is the normal arithmetic.

But in 2025-26 the reverse happened: harvest prices were already high, and the sale price fell to Tk 9–10. With an all-in cost near Tk 28/kg against a Tk 10 sale, farmers took heavy losses. This calculator’s loss warning exists to catch exactly that situation.

Remember: rent is a seasonal flat rate — taking potatoes out early still costs the full rent (no confirmed discount). So before deciding to store, run the numbers with a conservative sale price (e.g. last year’s lowest).

Frequently asked questions

What is the cold storage rent for potatoes now?

The government cap is Tk 6.00/kg (valid till 31 Dec 2026). Rajshahi charges Tk 5.75/kg. That is Tk 300 rent per 50 kg sack. Owners claim their cost is Tk 9.62/kg.

Is the 50 kg sack really mandatory?

Yes, the 50 kg sack rule has applied to cold storage since 2025. This calculator treats one sack as exactly 50 kg.

When do potatoes go into storage and come out?

They go in during the harvest season (February–March) and come out for sale in October–November. Ownership must be transferred by 15 November.

Does taking potatoes out early reduce the rent?

No — rent is a seasonal flat rate per kg, not prorated by month. No early-withdrawal discount is confirmed.

How much is lost to drying and rot?

BINA puts shrinkage at about 10%. This calculator defaults to 7.5%, adjustable from 5–10% with the slider.

How do I account for transport, labour and sacks?

Enter truck hire plus loading/unloading together per sack (usually Tk 65–100 a sack). Fold labour and sack costs into the same transport figure.

What is the break-even price? Is it better to sell now?

Break-even is your all-in cost per saleable kg — selling below it means a loss. If the expected price is lower, selling now or not storing at all may be better.
