Dropshipping Cost Calculator: Every Cost That Reduces Your Profit
Profit is what remains after costs. In dropshipping the cost stack is longer than many beginners realize: supplier, shipping, payment processing, advertising and platform fees. This page focuses exclusively on identifying and quantifying every cost so the profit calculation is realistic.
Once you have accurate costs, feed them into the free Dropshipping Profit Calculator to see net profit and margin.
The Main Cost Categories
1. Supplier / Product Cost
The price you pay the supplier for one unit. Always use the actual price after any quantity discounts or negotiated rates.
2. Shipping to Customer
The amount the supplier or 3PL charges to deliver the order. This can be flat, weight-based or country-specific. For international shipping watch currency conversion and unexpected duties.
More detail is available on the dropshipping shipping cost calculator page.
3. Payment Processing Fees
Stripe, PayPal, Shopify Payments and most gateways charge a percentage plus a fixed fee (commonly 2.9 % + $0.30). On a $30 order this is roughly $1.17. High-volume stores sometimes negotiate lower rates.
See the dropshipping fees calculator for a deeper look at payment and platform fees.
4. Advertising / Customer Acquisition Cost (CAC)
Total ad spend divided by number of orders. Include Meta, Google, TikTok and any other paid acquisition. This is usually the largest variable cost for paid-traffic stores.
Detailed treatment is on the dropshipping advertising cost calculator page.
5. Platform & Other Fees
Shopify, apps, currency conversion, or marketplace fees if you also sell on other channels.
6. Refunds & Chargebacks
Estimate the percentage of orders that result in a full or partial refund. When a refund occurs you typically lose the product cost, shipping and often the advertising spend.
How to Calculate Total Cost per Order
The main Dropshipping Profit Calculator performs this calculation instantly.
Practical Example
Supplier $9.80 + Shipping $3.40 + Payment $1.32 + CAC $11.50 + small platform fee ≈ $26.00+ total cost on a $34.99 selling price, leaving roughly $7–8 net before refunds.
Understanding each line item lets you attack the largest costs first (usually advertising and supplier price).

Frequently Asked Questions
What costs should a dropshipping cost calculator include?
Supplier product cost, shipping to customer, payment processing fees, advertising or CAC, platform fees, and any expected refund or chargeback costs.
What is the biggest cost in dropshipping?
For most paid-traffic stores, advertising (CAC) is the largest single cost, followed by product + shipping. Ignoring ads produces completely unrealistic profit figures.
How do I calculate total cost per order?
Add supplier cost + shipping + payment fees + CAC + platform fees + refund allocation. The Dropshipping Profit Calculator does this automatically.
Should I include refunds in the cost calculation?

Yes. Always model the shipping rates that apply to the countries you actually sell to.
How often should I update cost inputs?
Whenever supplier prices, shipping rates, payment fees or average CAC change.
