Cost and Returns

The grain is cheap; the money is in storing, grading and processing it.
Cost and Returns · Pillar 05

This is the pillar that decides whether maize is a business worth entering, and it demands an honest answer. In 2026 that answer is uncomfortable: at the average yield and the current market price, growing maize loses money. But that headline hides the real story, which is that profit in maize is not decided by whether you grow it, but by three things you control, how much you harvest per acre, when you sell, and how much of your cost is wasted labour. Get those right and maize pays well; get them wrong and no amount of hard work saves it. This pillar shows the numbers behind that claim and where the levers are.

What this shows

Officially reported costs sit alongside the labour and input lines that make up the rest of the build. Labour (planting, weeding, harvesting, shelling) is about half the total, which is exactly why mechanising it is the biggest cost lever, and a business in its own right.

The cost of growing an acre of maize rose from about GH¢1,200 in the 2020/21 season to about GH¢8,100 in 2024, a rise of roughly 575 percent, driven by fertiliser, agrochemical and labour costs (Peasant Farmers Association of Ghana, 2024). Only three items in that total are officially reported: seed at about GH¢1,100, fertiliser at around GH¢2,820 at the full recommended rate, and ploughing at about GH¢250 (Peasant Farmers Association of Ghana, 2024).

The remaining lines below are allocated to match the reported total and the known pattern that hired labour is about half of the cost. That single fact is the most important thing on the cost side: labour, not inputs, is where the money leaks, which is exactly why mechanising planting, weeding, harvesting and shelling is the biggest lever a maize business has.

There is a deeper problem hiding in that cost. Fertiliser, the biggest cash input, does not pay for most farmers at current prices. A 2024 study found the value-cost ratio of fertiliser on maize averaged about 2.2, meaning each cedi of fertiliser returned about 2.2 cedis of grain, but it was actually profitable, a ratio of 2 or more, for only about 28 percent of farmers, and only about half even broke even on it (Adzawla et al., 2024). When the main input loses money for seven farmers in ten, the case for free fertiliser and for closing the yield gap through better agronomy becomes not charity but basic economics.

Break-even at ~GH¢675
At about GH¢8,100 an acre and 12 bags, a farmer needs about GH¢675 per 100 kg just to break even.

🌽 The revenue side: a bumper harvest that crashed the price 🌽

Against that heavy cost, a typical smallholder harvests about 12 bags of 100 kg per acre, roughly 2.6 tonnes a hectare (United States Department of Agriculture, 2026). The problem in 2026 is the price. A bumper 2025 harvest, trapped behind the export ban, pushed the domestic price down to about GH¢360 per 100 kg by March 2026, a fall of roughly 49 percent in a year (United States Department of Agriculture, 2026). The state set a guaranteed farm-gate floor of GH¢450 per 100 kg in September 2025, which now sits above even the wholesale price of about GH¢360, so the market is trading below the floor, which is why the buffer-stock company is trying, and struggling, to buy up the surplus (Ministry of Food & Agriculture, 2025).

What this shows

The maize price fell about 49 percent to around GH¢360 per 100 kg by March 2026, below the government's GH¢450 floor. For a grower this is a loss-making price; for a buyer, processor or storer, it is cheap raw material.

🌽 Putting the two together: profit is a knife-edge

The margin depends almost entirely on the price and the yield, and small changes flip it from heavy loss to solid profit. The scenarios below hold the cost near GH¢8,100 an acre and vary the price and yield. They show the whole point of this pillar in a single table: maize is a knife-edge crop, and the reader who controls yield and timing lands on the profitable side of the edge.

The last row carries the lesson: at the same price, closing the yield gap turns a break-even into a strong profit.

At the same price, closing the yield gap turns a break-even into a strong profit.

The break-even makes the point sharply. At a cost of about GH¢8,100 an acre and 12 bags, a farmer needs about GH¢675 per 100 kg just to break even, well above the March 2026 price of about GH¢360. Put the other way, at the GH¢450 floor a farmer must harvest about 18 bags, roughly 4.5 tonnes a hectare, to break even, which almost no smallholder at the 2.6-tonne average reaches. That is the whole problem in one line: at today's prices, only the farmers who close the yield gap make money.

This is not only theory. Published field evidence shows the yield lever is real and large: maize farmers who accessed credit and inputs produced about 1.64 tonnes a hectare against 0.84 for those who did not, close to double (Asante et al., 2020). And smallholders are estimated to operate at only about 71 percent of the profit they could achieve, forfeiting nearly a third mainly to financial constraints (Anang & Shafiwu, 2022). The money left on the table is real, and it is mostly a finance-and-execution problem, not a farming one.

The sensitivity is easy to remember: at 12 bags an acre, every GH¢100 on the 100 kg price moves the net return by about GH¢1,200 an acre, and at GH¢700 every extra bag adds about GH¢700. The accompanying cost model lets you slide price, yield and cost to your own district.

🌽 Why a loss-making crop still matters, and where the money moved 🌽

Step back from the single farm and the economics look different, and this is the sourced, solid part of the analysis. Maize is Ghana's number one cereal and about a quarter of the calories the country eats, so its price feeds directly into food inflation and political stability (United States Department of Agriculture, 2026). The 2026 glut, painful as it is for farmers, has a national upside: it has made Ghana effectively self-sufficient in maize and cut the import bill, with maize imports falling from a drought-year peak of about 271,000 tonnes toward a forecast 30,000 tonnes (United States Department of Agriculture, 2026). Every tonne grown and used at home rather than imported saves foreign currency at a time when the cedi trades around GH¢11.2 to the US dollar (Bank of Ghana, 2026).

The commercial reading of this is important. When a country is short of a crop, the money is in growing more of it. When it is in surplus behind a closed border, as Ghana is now, the money moves downstream: to whoever can store the cheap grain, turn it into feed and food, and hold it until the price recovers or the border reopens. The farmer's loss in 2026 is the processor's and the storer's raw-material bargain. This is why the cost-and-returns story points straight into the value-chain and business-intelligence pillars that follow.

When a country is short of a crop, the money is in growing more of it. When it is in surplus behind a closed border, the money moves downstream, to whoever can store the cheap grain, mill it into feed and food, and hold it until the price recovers or the border reopens.

The farmer's loss in 2026 is the storer's and the processor's bargain. That is why this pillar points straight into the value-chain and business-intelligence pillars, where the storing, feed-milling and food-processing businesses are set out in full.

🌽 The Opening: cost and returns 🌽
01

Compete on yield, not acreage. At the same price, a 20-bag farmer makes a real profit where a 12-bag farmer breaks even. The whole return sits in closing the yield gap through better seed, fertiliser and timing, which is a market for input and advisory businesses.

02

Sell the timing, not just the grain. A farmer who can hold grain and sell in the lean season instead of the harvest glut recovers about 29 percent of value (see Pillars 3 and 6). Storage, warehouse receipts and pre-financing are the businesses that capture this.

03

Attack the labour cost. Labour is about half the cost of an acre. Mechanised ploughing, planting, weeding and shelling lower the farmer's cost and are service businesses in their own right (see Pillar 4).

04

Buy cheap in the glut, sell finished. For a processor or feed miller, the 2026 price crash is a raw-material bargain. Turning GH¢360 grain into feed, flour or fortified food is where the margin has moved.

🌽 The risks that sit inside the numbers 🌽

Price volatility and the glut

VERY HIGH
What it is

The maize price can swing by half within a year, and in 2026 it collapsed below the cost of production. A farm planned on last year's price can be wiped out by this year's.

Evidence

The price fell about 49 percent to around GH¢360 per 100 kg by March 2026, below the GH¢450 floor and well below the roughly GH¢675 break-even (United States Department of Agriculture, 2026).

Who it hits

Every grower, and any lender or aggregator exposed to the farm-gate price.

How to manage it

Do not plan a maize venture on a single price. Build in storage to sell later, secure an off-take contract at a fixed price where possible, and treat processing or feed as the natural hedge against a grain glut.

No published cost and returns sheet

MEDIUM
What it is

Ghana has no current, full cost-and-returns sheet for maize, so planning figures must be built from partial sources. A business built on wrong assumptions about cost, yield or price can fail even if the crop grows well.

Evidence

Only three cost items are officially reported; the rest of the build and the margin scenarios are allocated from partial data (Peasant Farmers Association of Ghana, 2024).

Who it hits

Investors and entrepreneurs relying on the numbers in this pillar without checking them.

How to manage it

Before committing money, check the cost build, the realised yield and the farm-gate price for the actual district and season, and use the cost model to test the numbers.

🌽 Key takeaways 🌽
01

At the 2026 average yield (about 12 bags an acre) and price (about GH¢360 per 100 kg), growing maize loses money; break-even needs about GH¢675 per 100 kg or about 18 bags an acre.

02

The cost of an acre rose about 575 percent in four years to around GH¢8,100, with hired labour about half of it, which makes mechanising labour the biggest cost lever.

03

Profit is decided by three controllable levers: yield (close the gap), timing (sell in the lean season, not the glut), and labour cost (mechanise it).

04

Nationally the glut is a win: Ghana is now effectively self-sufficient and its maize import bill has collapsed from about 271,000 toward 30,000 tonnes, saving foreign currency.

05

The money in 2026 has moved downstream, to storing, processing and feed-milling the cheap surplus, not to growing more grain at the average.

🌽 Practitioner intelligence 🌽

Hover any card to pause and lift it.

For students

This pillar teaches the most important business skill in farming: knowing your numbers. If you are entering maize, learn to build a real cost-and-returns sheet for a specific farm, because the published ones do not exist. A graduate who can sit with a farmer, capture the true cost, yield and price, and show where the money leaks is immediately useful to farmers, aggregators, lenders and this very project. The gap to fill: almost nobody has current, real farm budgets, which is why so much money is invested on guesswork. The downside to avoid is trusting unvalidated figures, including the ones here, as if they were checked; always confirm them in the field first.

For entrepreneurs

First move: do not enter maize as a plain grower at the average yield and price, because that loses money in 2026. Pick the profitable end instead, either produce high yields with good seed and timing and a secured buyer, or move downstream into storage, aggregation or processing where the cheap grain is a bargain. Secure the buyer or the off-take before you plant. The trap: borrowing to grow more maize at the average yield and selling into the harvest glut. The tailwind is the cheap 2026 grain, which favours anyone who can store or process it.

For investors

The thesis: at current prices the farm-gate is a poor bet but the downstream, storage, feed and processing, is a strong one, because the same glut that hurts the grower cheapens the processor's input. Diligence asks: validated cost, yield and price data, not partial estimates, a clear lever (yield, timing or processing margin), and a secured off-take. The risk: price volatility, so favour ventures with storage, fixed-price off-take or a processing margin that survives a grain glut.

For ecosystem actors

The lever: the highest-return move is de-risking the price for farmers so that closing the yield gap actually pays. Fund storage and warehouse receipts, make the guaranteed floor credible by funding the buffer-stock purchases, and support crop insurance. The measurable outcome is the share of farmers selling above break-even rising, and average yield climbing toward 4 tonnes a hectare. The failure to avoid is announcing a guaranteed floor price without the money to buy at it, which the 2026 buffer-stock funding gap shows can leave farmers worse off than no promise at all.
