Maize · Pillar 05

Cost and Returns

At the average yield and 2026 price, simply growing maize loses money, so the profit sits in three things you control: yield, the price you sell into, and cost. Labour is the largest block of that cost, which makes mechanising and moving into storage, grading and processing the real levers.
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

Brown bars are officially reported costs; gold bars are indicative estimates. Labour (planting, weeding, harvesting, shelling) is about 40 percent of the total in this build, nearer half if ploughing and bagging are counted, 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 costs1. Only three items in that total are officially reported: seed at about GH¢1,100, fertiliser at around GH¢2,820 an acre, and ploughing at about GH¢2501. The other lines are indicative estimates set to match the reported total.

Ghana has no published, up-to-date, full cost-and-returns sheet for maize, so the point of these numbers is to show the shape of the economics and where the levers are, not to give a bankable budget. The most important thing on the cost side is that labour, not inputs, is the largest block of the cost, which is exactly why mechanising planting, weeding, harvesting and shelling is the biggest lever a maize business has.

Inflation, costs and a moving market

Costs and prices also move with the wider economy, and not always together. Inflation eased from 23.5 percent in January 2025 to 3.2 percent in March 2026, the lowest reading since the consumer price index was rebased in 2021, then edged back up to 5.0 percent by August 2026, with food inflation at 3.0 percent234. Maize inputs are exposed to forces outside Ghana. Most seed and fertiliser inputs are imported, which ties their cost to the exchange rate1; the cedi lost about 9.5 percent against the US dollar in the first nine months of 20265; and the World Bank expects fertiliser prices to rise about 31 percent in 2026, with urea ending the year about 60 percent above 2025, because of conflict in the Middle East6. Borrowing is still costly, with the Bank of Ghana policy rate held at 14 percent in July 20267. The free 2026 fertiliser shields growers from this season’s spike, but a cost build that holds one season can be wrong the next, and a price fall can arrive in the same year as a cost rise. Re-cost inputs every season, hold a buffer against both a price fall and a cost rise, and prefer offtake contracts that fix the price or tie it to costs.

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 1.8 in the 2019 to 2021 seasons, meaning each cedi of fertiliser returned about 1.8 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 it8. When the main input fails to pay its way for seven farmers in ten, and loses money outright for about half, the case for free fertiliser and for closing the yield gap through better agronomy becomes 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 cost, a typical smallholder harvests about 12 bags per acre1, which at 100 kg a bag is roughly 3 tonnes a hectare, close to the national average of about 2.8 tonnes9. The problem in 2026 is the price. A bumper 2025 harvest, trapped behind the export ban and topped up by earlier imports, pushed the domestic price down to about GH¢360 per 100 kg by March 2026, a fall of roughly 49 percent in a year9. The state set a guaranteed farm-gate floor of GH¢450 per 100 kg in September 2025, which now sits above the March 2026 market 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 surplus10.

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 2024 cost near GH¢8,100 and vary the price and yield; farmers who receive the free 2026 fertiliser would face a lower cost. 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.

Close the yield gap
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 near the national average of under 3 tonnes reaches. At the March 2026 market price even a 20-bag farm loses money, and only farmers near 23 bags an acre, or those paid the floor, break even.

This is not only theory. Published field evidence shows the yield lever is real and large: maize farmers in one credit programme in Kwahu West produced about 1.64 tonnes a hectare against 0.84 for non-participants, close to double on a simple comparison11. And smallholders in Sagnarigu, in the north, were estimated to operate at about 71 percent of the profit they could achieve, and they named financial constraints as their biggest problem12. The money left on the table is real, and much of it comes down to finance and execution.

Stated as returns rather than cedis, the same scenarios run from about minus 33 percent at the GH¢450 floor, through roughly break-even at GH¢700, to about plus 60 percent for a well-run 20-bag farm. 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 set price, yield and cost for your own district.

🌽 Model it yourself 🌽

Numbers on a page are one thing. Move the levers yourself. The model opens on the 2026 reality, 12 bags an acre at the GH¢360 glut price, and it opens in the red at a loss of about GH¢3,780. Set the yield, the farmgate price and the labour bill to your own district, then swing them one at a time. Push the yield or the price slider and watch how far the net has to travel to clear the line, then push the labour slider and watch it barely stir. That is the argument of this pillar in one gesture: at the average, maize loses money, and the way out runs through yield and price, not cost-cutting.

Tool 1

Does the acre clear a margin?

Slide the three levers a grower can hold: the yield in 100 kg bags an acre, the farmgate price a bag, and the field labour bill, the largest block of the cost. The model opens on the 2026 reality, 12 bags at the GH¢360 glut price, and it opens in the red. Push the yield and the price sliders and watch how far the net has to travel to clear the line, then push the labour slider and watch it barely stir.

net an acre, against the GH¢5,400 a well-run farm makes at a recovery price
At these numbers the acre loses GH¢3,780, and the base case, 12 bags at the GH¢360 glut price, is the thesis of this pillar made live: at the 2026 average, growing maize loses money, about GH¢3,780 an acre. At 12 bags the acre needs about GH¢675 a bag just to break even, above the GH¢360 a bag in the model. Notice what pulls it back above the line. Cutting labour helps a little, but it is the yield and the price sliders that move the net, so the way out is more bags from better seed and agronomy, or a better price through storage and selling in the lean season, not the harvest glut.

Base case, per acre: the 2026 national average of 12 bags of 100 kg valued at the March 2026 glut price of GH¢360 a bag gives revenue about GH¢4,320; taking off the cost of about GH¢8,100 (non-labour lines 4,950: seed 1,100, fertiliser 2,000, agrochemicals 500, land preparation 250, bagging and transport 500, other 600; plus a field labour bill of 3,150) leaves a net of about minus GH¢3,780, a loss. Break-even needs about GH¢675 a bag at 12 bags, or about 23 bags at GH¢360. Cost is held at GH¢8,100, which reproduces the Sensitivity sheet cell for cell.

Tool 2

What swings the net most

The same model, re-run as a sensitivity read. Each bar is how far the net moves when that one driver changes by 20 per cent, holding the others where you left them. Two drivers lead by the same amount, and neither of them is a cost line.

1. The farmgate price you sell into±GH¢864

The price the market pays, not one the grower sets, and in 2026 it is the whole story: a bumper harvest trapped behind the export ban pushed it to about GH¢360 a bag, below the GH¢675 the acre needs to break even at the average yield. It moves the net as much as yield does, and lifting it runs through storage and processing (Pillars 3 and 6) and selling in the lean season, not the glut, rather than through the gate at harvest.

2. Yield, in bags an acre±GH¢864

How many 100 kg bags the acre actually brings in, about 12 at the national average and 20 on a well-run farm. It is the joint-widest lever and the one the grower can build through better seed, fertiliser and timing (Pillars 1 and 4), which is why closing the yield gap, not shaving a cost line, is what turns the 2026 loss into a profit at any given price.

3. The field labour bill±GH¢630

Planting, weeding, harvesting and shelling, about two-fifths of the cost of an acre (nearer half once ploughing and bagging are added), the largest block of cost and the one big cost the operator can actually cut through mechanised ploughing, planting, weeding and shelling (Pillar 4). It swings the net about a third as much as price or yield, so it is worth cutting and it is a service business in its own right, but it is not where the margin is won.

4. Fertiliser±GH¢400

The biggest cash input, and one that does not pay for most farmers at 2026 prices: the value-cost ratio averaged about 1.8 in the 2019 to 2021 seasons and was only profitable for about 28 per cent of growers. As a swing on the net it is a distant fourth, well behind the two revenue drivers.

5. Seed±GH¢220

Improved or OPV seed. Clean, certified material earns its keep by lifting the yield rather than by being cheap; as a cost line on its own it is the smallest swing of all.

±GH¢864
What a 20 per cent change in the price or the yield does to the net
±GH¢220
What a 20 per cent change in seed does, the smallest swing of all
The farmgate price and the yield swing the net most and by the same amount, the field labour bill moves it about a third as much, and fertiliser and seed barely register. That is the argument of this whole pillar in one gesture: at the 2026 average maize loses money, and the two levers that flip it are both revenue drivers, the yield the grower builds through agronomy and the price the grower reaches through storage and processing, not the cost lines. It also means the acre is dangerously exposed to a price fall, which is exactly the glut that put the base case in the red.

Sensitivity holds two levers where you left them and moves the third by 20 per cent: the price and the yield both act on revenue, so they lead and tie; the field labour bill is the biggest controllable cost and swings the net about a third as much; fertiliser and seed are input lines that barely move it. Ranks match the Sensitivity sheet of the Maize Cost and Returns Model, where moving across a price column and moving down a yield row shift the net by the same large amount and the cost is held at GH¢8,100.

🌽 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 stability9. 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 tonnes9. 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 dollar13.

Turning GH¢360 grain into flour and fortified food is where the margin has moved.

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. 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 can capture a seasonal price rise of about 33 percent, though storage and interest costs absorb much of it (see Pillars 3 and 6). Storage, warehouse receipts and pre-financing are the businesses that capture this.

03

Attack the labour cost. Labour is the largest block of 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 at twelve bags an acre9

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.

🌽 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 at the GH¢450 floor (about 23 bags at GH¢360).

02

The cost of an acre rose about 575 percent in four years to around GH¢8,100, with hired labour the largest block 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 are partial. 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: few people hold current, real farm budgets, which is why so much money is invested on guesswork. The downside to avoid is planning on indicative numbers without checking 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: the cost, yield and price data behind the plan, 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 shortfall shows leaves most farmers selling below the promised price.
