Dropshipping is a business model with unique cost structures, as you don't hold inventory or directly handle shipping. Instead, your focus is on setting prices that cover costs (paid to the supplier) and marketing expenses while ensuring profitability. Let’s break down unit price economics and break-even analysis for a dropshipping business selling smartphone covers.
Before calculating the unit price and break-even point, understand the costs involved:
The price you pay your supplier for each smartphone cover.
The fee charged by your supplier for shipping the product to your customer.
In dropshipping, most sales come from paid ads (e.g., Facebook, Instagram, Google). The ad spend per customer acquisition must be considered.
Costs from payment processors or your e-commerce platform.
- Example: Stripe or PayPal may charge 2.9% + $0.30 per transaction.
The profit you want to make after covering all costs.
Let’s assume the following example costs for your dropshipping business:
| Cost Component | Amount (per unit) |
|----------------------------------|------------------------------------|
| Supplier Price (COGS) | $4.00 |
| Shipping Cost (Supplier to Buyer)| $3.00 |
| Marketing/Ad Cost per Sale | $4.00 |
| Transaction Fee (e.g., Stripe) | 2.9% + $0.30 |
Unit Cost = Supplier Price + Shipping + Marketing + Transaction Fee
Transaction Fee = (Selling Price × 2.9%) + $0.30
Let’s calculate the total cost at different selling prices:
| Selling Price | COGS | Shipping | Marketing | Transaction Fee | Total Unit Cost |
|--------------------|----------|--------------|---------------|---------------------|---------------------|
| $10 | $4.00 | $3.00 | $4.00 | $0.59 | $11.59 |
| $15 | $4.00 | $3.00 | $4.00 | $0.74 | $11.74 |
| $20 | $4.00 | $3.00 | $4.00 | $0.88 | $11.88 |
Once you know your total unit cost, decide your desired profit margin.
Selling Price = Unit Cost ÷ (1 - Desired Profit Margin)
Selling Price = $11.59 ÷ (1 - 0.50) = $11.59 ÷ 0.50 = $23.18
| Unit Cost | Profit Margin | Selling Price |
|---------------|-------------------|-------------------|
| $11.59 | 50% | $23.18 |
| $11.74 | 50% | $23.48 |
| $11.88 | 50% | $23.76 |
The break-even point tells you how many smartphone covers you need to sell to cover all your fixed and variable costs.
Break-Even Point (Units) = Fixed Costs ÷ (Selling Price - Variable Costs)
Total Fixed Costs: $79/month
Variable Costs:
Include COGS, shipping, marketing, and transaction fees.
Contribution Margin = Selling Price - Variable Costs
Contribution Margin = $23.18 - $11.59 = $11.59
Break-Even Point = Fixed Costs ÷ Contribution Margin
Break-Even Point = $79 ÷ $11.59 = 6.8 units
You need to sell 7 smartphone covers at $23.18 each to break even and cover all costs.
Offering bulk discounts can increase average order value (AOV) but may reduce per-unit profitability. Let’s calculate for a 3-pack and 5-pack scenario.
| Quantity | Discounted Price (Each) | Total Price |
|--------------|-----------------------------|-----------------|
| 1 Cover | $23.18 | $23.18 |
| 3 Covers | $20.00 | $60.00 |
| 5 Covers | $18.00 | $90.00 |
Total Variable Costs = $12 + $9 + $4 + $2.04 = $27.04
Selling Price: $60.00
Variable Costs: $27.04
Contribution Margin = $60 - $27.04 = $32.96
Fixed Costs = $79
Contribution Margin (Per 3-Pack) = $32.96
Break-Even Point = $79 ÷ $32.96 = 2.4 (round to 3 orders)
You need to sell 3 bulk orders of 3 covers to break even.
If shipping is passed to the customer, your variable costs decrease, increasing your contribution margin and reducing the break-even point.
