Will your maize last to the next harvest?
Count what is in your store against what your household eats, and see whether it reaches the June harvest — plus how big the gap is, months before it arrives.
Before you decide whether to sell maize, it is worth knowing how much of it your family is going to eat.
This page does that arithmetic. Put in what is actually in your store, how many people eat from it, and it works out roughly how long it lasts, whether it reaches the next harvest, and how big the gap is if it does not. Nothing is sent anywhere — the numbers stay in your phone.
It is the question that comes before the store-or-sell page. Grain sold in June and bought back in February is the most expensive trade a household can make, and it is easy to make by accident when nobody has counted.

National average: How much maize is available per person across the whole of Malawi, town and country together. It is the lowest of the three because it includes households that eat a lot of rice, cassava and bought food. Malawi's figure has moved between about 128 and 157 kg over the last ten years; this is the most recent. FAOSTAT Food Balance Sheets — Malawi, maize and products, food supply per person (2023-12-31)
On these numbers the store runs out about 3.5 months before the June harvest. That gap is bought at the dearest time of the year, or covered some other way.
That works out at about 53 kg of maize a month for the household.
A gap is not only a shopping list
This is arithmetic, not a forecast
Worth knowing
When the harvest actually comes
Malawi has one maize harvest a year. It starts in the south around April and works north, so around Mzuzu and Mzimba the grain is usually in the store through May and June. Green maize can be eaten from about February in a good year, but it is not a store — it is eaten as it comes. This page counts to the next full harvest, so in the months after June it is counting almost a whole year ahead.
What the store itself takes
Grain in the store is not the same as grain on the plate — weevils and the larger grain borer take a share, and the share grows the longer it sits. The figures here follow measured smallholder maize storage studies for the region (APHLIS / EU JRC; Dijkink and others, 2022), which cover roughly the first eight months; the twelve-month point is the upper end of the range those studies report for a full season in ordinary storage. How much you actually lose depends most on drying the grain properly, keeping the store clean, and whether you treat it. Airtight or PICS triple bags hold measured losses to around one or two percent even after a whole season — which, on the numbers this page works out, is often worth more than any price you could get for the grain. This page also allows for how long the maize has already been sitting: grain that came in at the last harvest is further along that curve than grain just brought in.
Why the published figures disagree
These three figures are all real and all published, and they differ by more than double. That is not a mistake in any of them — they count different people. A national average includes cities and households that eat rice and cassava; a farming household that eats nsima twice a day eats far more maize than the average Malawian. Nobody can tell you which one fits your house. If you know roughly how often you open a bag, that answer beats all three, which is why it is the first choice on this page.

- Farming household, maize at every meal — 300 kg a person a yearWhat a district's own food-security planning assumes for farming households where maize is nearly the whole diet — nsima twice a day, little bought food. This is the figure used for Salima District in Central Malawi, not for Mzimba, so treat it as the top of the range rather than a local measurement. If your household buys little and grows most of what it eats, you are closer to this end than to the national average.Government of Malawi district data, as used in Ngwira and others, Central Malawi maize study (2018-12-31)
