Cost & price
What it really does
It adds up everything you spent to get one item (or one service) ready to sell. Then it tells you the price to charge so you make the profit you want. No more guessing.
What you need
The price you paid, how many you bought, and any other costs, like shipping, ads, delivery or data.
How to fill it in
- Choose Product or Service.
- Product: say if you bought it from a supplier in your country or imported it. Type the quantity and the price of one unit. If you imported it, choose the money you paid in. If it isn’t your money, type the exchange rate. Then type the shipping for this item, or pick a shipping fee you saved earlier.
- Service: list the supplies you use up, like ingredients or items, and what each one costs. If your supplies can make many items (say 20 cakes), type how many. The cost is shared across them.
- Other expenses: add anything else that costs you money, like ads, delivery or data. Tap a quick-add button, or + Type your own. Choose once if the amounts are for the whole batch or for each unit.
- Shop costs & salaries (optional): tick the box if you want your rent and salaries counted too. Add each cost and how often you pay it. Then type the total number of items and the total value of goods you have available.
- Selling price: tick the box. Choose margin or markup, type the profit you want, add any platform fee, and choose how to round. Already have a price? Type it to see your profit.
What the answers mean
- Total cost (landed cost): everything you spent on the whole batch.
- Cost per unit: the total cost divided by the quantity. This is what ONE item really costs you.
- Suggested selling price: the price that gives you the profit you asked for, after any platform fee, rounded up.
- Profit per unit and total profit: the money you keep.
- Margin and markup: your profit shown as a percentage, in two ways.
- Break-even price: if you sell below this, you lose money.
Example. 100 boxes at ₦500 each is ₦50,000. Add ₦8,000 shipping and ₦2,000 of ads, and the total cost is ₦60,000. Divide by 100 and each box costs ₦600. For a 30% margin, ₦600 ÷ (1 − 0.30) is about ₦857. Rounded up to the nearest ₦100, you sell at ₦900. Your profit is ₦300 a box, or ₦30,000 in all.
Shop costs example. Your rent is ₦50,000 a month and the goods you have are worth ₦500,000. That is 10%, so every item’s cost goes up by 10%. This way each item pays its fair share of the rent.
Service example. A ₦6,000 pack of gel can make 20 sets. Type 20 in “how many items can these supplies make” and each set carries ₦300 of gel.
Shipping fee
What it really does
It works out what a shipping company will charge for your goods, using their rate. By air they charge by weight (kg). By sea they charge by the space your goods take up (CBM). It adds any customs and other fees, then shows the total and the shipping for each piece.
What you need
The shipping company’s rate, and the total weight of your shipment (air) or its size or total CBM (sea).
How to fill it in
- Choose Air (kg) or Sea (CBM).
- Type the rate your shipping company charges: per kg for air, per CBM for sea. If it isn’t in your money, type the exchange rate they use.
- Type the item name and the total weight of your shipment. The number of pieces is optional. Add it if you also want the shipping for each piece.
- Air: type the total weight in kg. Optional: tick Check volumetric weight too and type the size of one piece and the number of pieces.
- Sea: type the size of one piece in cm and the number of pieces, and the app works out the CBM. If you already know the total CBM, choose that and type it.
- Optional: add a customs / clearing fee (charged per kg for air, per CBM for sea) and any other fees, like pickup or local transport.
What the answers mean
- Charged on: the kg or CBM your shipping company will bill you for.
- Freight charge: the rate multiplied by that number.
- Total shipping fee: the freight charge plus all your extra fees.
- Shipping per piece: the total divided by the number of pieces. Add this to each item’s cost.
Why volumetric weight? A light but bulky box takes up a lot of space on a plane. So the airline compares the real weight with the “space weight” (length × width × height in cm, divided by 6000) and charges whichever is bigger.
Air example. A shipment of 15 kg at ₦14,000 per kg costs 15 × 14,000 = ₦210,000. Add ₦2,000 for pickup and the total is ₦212,000.
Sea example. 10 boxes of 40 × 30 × 30 cm. Each box is 0.036 CBM, so 10 boxes are 0.36 CBM. At ₦100,000 per CBM, shipping is ₦36,000.

Bulk shipping split
What it really does
When goods arrive in one shipment, you get one shipping bill. This calculator shares that bill across your items, so each item gets its own shipping cost. Think of sharing a restaurant bill: everyone pays for what they had.
What you need
The total shipping you paid, and your list of items with their quantities. Prices, weights or CBM are optional, but they make the split fairer.
How to fill it in
- Name the shipment and type the total shipping you paid. Add the exchange rate if needed, and any other shared fees like clearing or delivery.
- Add each item with its quantity. If you know them, add the price per unit, the weight or the CBM.
- Choose how to split. Best estimate is recommended.
How the split works
- Weight: heavier items carry more of the shipping.
- Volume (CBM): bigger items carry more.
- Value of goods: more expensive items carry more.
- Number of units: every unit carries the same.
- Best estimate: uses weight if every item has one. If not, it tries CBM, then value, then number of units.
What the answers mean
- Share: the part of the shipping each item carries, as a percentage.
- Shipping for item: that share in money.
- Shipping per unit: the amount to add to the cost of one unit.
Example. 500 boxes at ₦300 are worth ₦150,000. 500 mailers at ₦120 are worth ₦60,000. Together that is ₦210,000. Share ₦500,000 of shipping by value: the boxes carry about 71% (₦357,143, or ₦714 a box) and the mailers about 29% (₦142,857, or ₦286 a mailer).
This is an estimate, not an exact bill. If you know real weights or CBM, add them for a closer answer. Tap Save this split to keep it.
Bulk cost price
What it really does
You bought many different items at once. This finds the cost price of each item: what you paid for it, plus its fair share of the shipping or delivery and your other expenses. Imported and local purchases are kept apart, because their costs are different.
What you need
Your list of items with quantities and buying prices. For an imported purchase, the total shipping fee. For a local purchase, the waybill or delivery fee. Plus any other expenses.
How to fill it in
- Choose Imported or Bought in my country. They have their own boxes and their own items.
- Imported: type the total shipping fee you paid, the money you paid it in, and the money the items are priced in. Add exchange rates if needed. Then add other expenses like clearing or delivery to you.
- Bought in my country: type the waybill / delivery / transport fee and the packaging. Then add other expenses.
- Add your items with the quantity and the buying price of one unit. For imported items you can also add weight and CBM to make the split fairer.
- Optional: add your shop costs and salaries. Tick the selling price box to get a price and profit for each item. You can type your own selling price for any item.
What the answers mean
- Cost price per unit: what one of that item really cost you, with everything added.
- Total cost: what the whole purchase cost you.
- Selling price and profit: shown for each item if you ticked the selling price box.
Imported example. 500 mailers at ₦120 cost ₦60,000. 200 rolls of tape at ₦600 cost ₦120,000. Shipping is ₦100,000 and clearing is ₦20,000, so ₦120,000 is shared by value. Mailers take ₦40,000 and tape takes ₦80,000. Each mailer costs (60,000 + 40,000) ÷ 500 = ₦200. Each roll of tape costs (120,000 + 80,000) ÷ 200 = ₦1,000.
Local example. 500 boxes at ₦300 cost ₦150,000. Add ₦5,000 for the waybill and ₦1,000 for packaging, and each box costs (150,000 + 6,000) ÷ 500 = ₦312.

Questions people ask
What do I type for the exchange rate?
Type how much one unit of the other money is worth in yours. If one dollar costs 1,500 naira, type 1500. If you pay in your own money, choose your own currency in the list and no rate is needed.
What if I don’t know the weight or CBM?
Leave it empty. The calculator uses another clue, like the value of the goods, and tells you which one it used.
What is the difference between margin and markup?
Margin is your profit as a share of the selling price. Markup is your profit as a share of your cost. If an item costs ₦600, a 30% markup gives ₦780 and a 30% margin gives about ₦857.
What is the shop costs percentage?
Your monthly rent and salaries are divided by the total value (or number) of goods you have available. That gives a small percentage, which is added to each item’s cost. This way every item pays its fair share.
Does it include import duty and taxes?
Not in its own box. Add duty and taxes as an expense under Other expenses. On the Shipping fee page you can also use the customs / clearing fee.
Where are my saved items?
At the bottom of each calculator, on the phone or browser where you saved them. To open your items on any device, log in and tap View Catalog.
Why do some answers say “estimate”?
When you split one shipping fee across many items, the calculator shares it using the best clues you gave. It is a fair guess, not an exact invoice.
Can I use it on a laptop?
Yes. It opens in any browser on a phone, tablet or laptop.
