Search for this and you'll find answers from ₦500,000 to ₦20 million. They can't all be describing the same shop, and they aren't. A kiosk-sized provision store in Ilorin and an air-conditioned mini mart in Lekki share a name and almost nothing else.
So instead of handing you one figure, this guide shows where the money goes and how to work out your own number.
What published estimates say
Nobody publishes official data on the cost of opening a small shop in Nigeria. What exists are estimates from people who sell to shop owners.
One of the more detailed is from SwiftPOS, a Nigerian point-of-sale company. Its June 2026 guide puts a mini mart in a major city at roughly ₦3 million to ₦10.8 million, broken down like this:
| Item | Low estimate | High estimate |
|---|---|---|
| Shop rent, first payment | ₦300,000 | ₦2,500,000 |
| Shop fitting and interior | ₦200,000 | ₦1,000,000 |
| Opening stock | ₦1,500,000 | ₦4,000,000 |
| Equipment | ₦400,000 | ₦1,500,000 |
| POS hardware | ₦80,000 | ₦250,000 |
| Staff, three months | ₦200,000 | ₦450,000 |
| Registration and permits | ₦20,000 | ₦110,000 |
| Working capital buffer | ₦300,000 | ₦1,000,000 |
SwiftPOS says the figures reflect Lagos, Abuja, Port Harcourt and Ibadan, and that smaller towns come in 20 to 40% lower. They are that company's own estimates, not survey data, and it sells POS systems. Treat the table as a checklist of what to budget for, not as a quote.
The useful thing in it is the shape. Stock and rent are most of the money. Everything else is small beside them.
The three numbers that decide your total
Rent, and how many years the landlord wants. This is the biggest swing. The same size of shop can cost several times more on a busy road than inside an estate, and many landlords ask for one or two years upfront, plus agency and agreement fees. Get the real figure for the actual shop before you budget anything else.
How much you put on the shelves. Opening stock is where new owners overspend. A full-looking shop feels safe, so they buy a little of everything, and three months later half of it hasn't moved.
Power. If you plan to sell cold drinks and frozen food, you need a freezer and a way to keep it running. A generator or inverter, and the fuel or batteries to feed it, can cost more than your shelves.
Building your own budget
Take a sheet of paper and get real quotes for each line. Don't use anyone's range, including the one above.
- Premises. Rent for the period demanded, agency fee, agreement fee, any deposit.
- Fitting. Shelves, counter, signboard, painting, lighting, burglar-proofing. Ask a carpenter and a welder for prices, and look at used shelving.
- Cold storage and power. Only what your product range needs.
- Opening stock. See the next section.
- Registration. Business name registration, local government permits and any levies for your area. Ask a shop owner on the same street what they actually pay each year.
- Selling equipment. A POS terminal for card payments, a calculator, a receipt booklet. Barcode scanners and software can come later.
- Running costs for three months. Salaries, fuel, data, transport. A new shop rarely covers its costs in the first weeks.
- A reserve. Money you don't plan to spend. Something will cost more than quoted.
Add it up. That's your number, and it's more reliable than any article's.
Spend less on opening stock than you think
Stock is the one line you can deliberately shrink without hurting the shop.
Start narrow. Walk the area and write down what the nearest shops sell most and what people have to travel for. Open with the everyday items every household buys, in modest quantities, and add lines as customers ask.
Keep a third of your stock budget back as cash. In the first month you will learn what your customers really want, and it won't match your guess. The money you held back buys more of what's selling.
Buy fast sellers by the carton and unknowns by the half-dozen. A slow item you bought six of is a lesson. A slow item you bought six cartons of is a problem. If it happens anyway, here is what to do with goods that won't sell.
The cost nobody budgets for
Almost no start-up guide lists losses. But a new shop with new staff, no records and an owner busy with everything else is at its most exposed. Goods get miscounted on delivery, prices get guessed, and small items walk.
You prevent this with habits, not money, and it's far easier to start them on day one than to introduce them in month six:
- A written price list before the first sale.
- A sales record book from the first day, closed every evening.
- A stock record for your top items, started from the opening delivery.
- A weekly count of the goods most worth taking.
The opening delivery is the only time in the shop's life when you know exactly what's on the shelves, because you just paid for all of it. Write it down then. Every shop that didn't wishes it had.
So, how much?
For a small neighbourhood shop in a low-rent area, selling dry goods from simple shelves, the total can be modest. For a fitted, cooled mini mart on a busy road in a big city, it runs to many millions, mostly in rent and stock. Your figure sits wherever your rent, your range and your power needs put it.
Get the rent quote first. Then decide how narrow you can start. Those two choices set most of the bill. For running the shop once it's open, see how to run a successful provision store.
