How to Price Your Products Without Guessing
Most WhatsApp vendors price by looking at what competitors charge. If another phone dealer charges ₦850K for an iPhone 15 Pro, you do too. If a fashion vendor on Jiji lists a dress for ₦15K, you match it. The problem: you have no idea if that's actually profitable for you.
Pricing isn't random. It's math. This guide gives you the exact formula for phones, fashion, food, and other products—and shows you how to use it to guarantee you're making money, not just moving inventory.
The Universal Pricing Formula
Price = (Cost + Fixed Costs) ÷ (1 - Target Margin)
That's it. Let me break it down:
- Cost: What you paid for the product
- Fixed Costs: Your monthly expenses divided by expected sales
- Target Margin: How much profit you want (usually 25-50%)
Example: Phone Dealer
You're buying iPhones at ₦850K (your cost) and want to sell them at some price.
- Your cost: ₦850,000
- Monthly fixed costs: ₦200K (rent, transport, WhatsApp data). You sell 4 phones/month, so ₦200K ÷ 4 = ₦50K per phone
- Target margin: 30% profit (you want to keep ₦280K/phone after costs)
Formula: (₦850K + ₦50K) ÷ (1 - 0.30) = ₦900K ÷ 0.70 = ₦1,285,714
So you should charge ₦1.29M minimum. Anything less and you're working at a loss.
Real Examples by Business Type
Fashion/Clothing
| Product | Your Cost | Fixed Cost/Unit | Target Margin | Minimum Price |
|---|---|---|---|---|
| Designer Dress (Imported) | ₦8,000 | ₦2,000 | 40% | ₦16,667 |
| Bulk Jeans | ₦3,500 | ₦800 | 35% | ₦6,615 |
| Shoes | ₦2,500 | ₦600 | 45% | ₦5,636 |
The key: imported items = higher margin (40-45%), bulk local items = lower margin (30-35%).
Food/Catering
| Dish | Ingredient Cost | Fixed Cost/Unit | Target Margin | Menu Price |
|---|---|---|---|---|
| Jollof Rice + Meat | ₦1,800 | ₦600 | 50% | ₦4,800 |
| Shawarma | ₦1,200 | ₦400 | 55% | ₦3,911 |
| Pizza (Large) | ₦2,200 | ₦800 | 60% | ₦7,500 |
Food margins are highest (50-60%) because of perishability and labor. If you're not hitting 50%+, you're underpricing.
Electronics/Gadgets
| Item | Your Cost | Fixed Cost/Unit | Target Margin | Price |
|---|---|---|---|---|
| iPhone 15 Pro | ₦850,000 | ₦50,000 | 25% | ₦1,200,000 |
| Refurbished iPhone | ₦380,000 | ₦30,000 | 30% | ₦588,571 |
| AirPods | ₦45,000 | ₦5,000 | 40% | ₦83,333 |
Electronics = lower margins (25-30%) because of fast discounting and competition. Accept this and focus on volume.
How to Calculate Your Own Fixed Costs
This is where most vendors go wrong. They forget fixed costs, then sell at a "profit" but actually lose money.
Step 1: List All Monthly Expenses
- Rent (if you have a shop) or portion of home if you work from home
- Data/internet
- Transportation to meet clients
- Packaging materials
- Staff (if applicable)
- Advertising (if you do any)
- Bank fees
Let's say you spend ₦300K/month on all of this.
Step 2: Estimate Monthly Sales
How many items do you sell per month? Be realistic. If you're new, 10 items. If you're established, 50 items.
Let's say 20 items/month.
Step 3: Calculate Fixed Cost Per Unit
₦300K ÷ 20 items = ₦15K per item
This means every item you sell needs to cover ₦15K of your monthly expenses, before profit.
Finding Your Target Margin
Most vendors don't have a "target margin"—they just price randomly. Don't do this. Set one based on your business type:
| Business Type | Realistic Margin | Why |
|---|---|---|
| High-volume, low-cost (fashion, food) | 40-60% | People expect lower prices; you make profit from volume |
| Medium-volume, medium-cost (electronics) | 25-35% | Competition is fierce; margins are thin but sales are high |
| Low-volume, high-cost (bulk orders, equipment) | 15-25% | Few sales; need profit per transaction to survive |
| Services/custom work (catering, alterations) | 50-70% | Labor-intensive; higher margins justify time investment |
Common Mistakes to Avoid
Mistake 1: Forgetting Shrinkage
Clothes get damaged. Phones get returned. Food spoils. Add 5-10% to your cost to account for this. If your actual cost is ₦8,000, calculate as ₦8,400.
Mistake 2: Undercounting Fixed Costs
You work 60 hours a month. That's your time. Add a nominal cost for it. Even if you don't pay yourself, your time is worth something. Add ₦3-5K/item minimum.
Mistake 3: Not Adjusting for Volume
If you triple your sales volume, your fixed cost per unit drops. A ₦50K monthly expense becomes ₦8.33K per item if you sell 60 items instead of 10. You can drop prices as volume increases.
Mistake 4: Matching Competitors
Competitors may have lower costs (they buy in bulk, have unpaid family labor, or are pricing wrong). Use math, not Instagram prices.
The 4-Step Pricing Process
- Calculate cost: What did you actually pay?
- Calculate fixed cost per unit: Monthly expenses ÷ expected monthly sales
- Pick target margin: What % profit do you want?
- Use formula: (Cost + Fixed) ÷ (1 - Margin) = Price
Do this for your top 5 products. It takes 30 minutes. This 30 minutes could earn you thousands in extra profit per month.
Bottom Line
Most vendors are underpricing by 20-30%. Not because they're generous, but because they don't know their numbers. Use this framework. Calculate your prices properly. You'll make more money per sale and have proof that every sale is profitable.
