Dropshipping Calculator for Profit, Pricing & ROI
This dropshipping calculator works out the true profit of a product after every cost is counted — supplier price, shipping, platform commission, payment processing, and ad spend. Enter your numbers and the net profit, margin, ROI, and breakeven price update instantly.
It is built for dropshippers and ecommerce sellers vetting products before they commit budget. Whether you source from AliExpress, sell on Amazon FBA, or run a Shopify store, the calculator handles each platform's fee structure so the margin you see is the margin you actually keep.
How to Calculate Dropshipping Profit

Fill in the Product Cost from your supplier, the Shipping Cost to the customer, and any Other Costs such as packaging or handling per unit.
Set your fees
Add the Platform Fee (e.g. 15% on Amazon), the Payment Processing Fee as a percentage plus a fixed amount (e.g. 2.9% + $0.30), and your Advertising Cost per unit sold.

Frequently Asked Questions
How do you calculate dropshipping profit?
Subtract every cost from your selling price. Add up the product cost, shipping, other per-unit costs, advertising, and the platform and payment fees — the platform and payment percentages are applied to the selling price — then deduct that total. What is left is your net profit per unit. This calculator does all of it for you as you type.
How do you calculate dropshipping profit margin?
Profit margin is net profit divided by the selling price, shown as a percentage. If a $40 product leaves $10 of net profit, the margin is 25%. The calculator reports this margin automatically alongside ROI and breakeven.
What is a good profit margin for dropshipping?
Many dropshippers aim for a net margin of roughly 15–30% after all fees and ad spend, though the right number depends on your price point, niche, and advertising cost. Use Calculate Selling Price mode to set a target margin and see the price it requires, then sanity-check it against the market.
What costs go into a dropshipping profit calculation?
The calculator counts product cost from your supplier, shipping to the customer, other per-unit costs (packaging, handling, returns), platform commission, payment processing fees (percentage plus fixed), and advertising cost per unit. Put any recurring per-unit expense not covered by a dedicated field into Other Costs.
What is the difference between profit margin and ROI?
Profit margin is net profit as a percentage of the selling price — it shows what fraction of each sale is profit. ROI is net profit as a percentage of your total costs — it shows how much you earn relative to what you spend. The calculator displays both so you can compare products fairly.
How is the breakeven price calculated?
The breakeven price is the lowest selling price at which net profit equals zero. It accounts for all fixed per-unit costs (product, shipping, ads, other, plus the fixed payment fee) and the percentage fees for platform and payment processing. Selling below this price means losing money on every order.
Why does the Amazon FBA preset use a 0% payment processing fee?
Amazon bundles payment processing into its referral fee, so the preset uses a single 15% platform fee with no separate payment charge. Platforms like Shopify rely on an outside gateway (Stripe, PayPal) that adds its own fee, which is why those presets include a payment processing percentage and a fixed amount.
