What Is Net Earnings
Net earnings is the actual amount of money a seller keeps after all fees are taken out of a sale. When you sell something on a marketplace like Whatnot, the platform takes out several types of fees before paying you. These fees may include a selling fee based on the sale price, payment processing costs, and sometimes fixed charges per transaction. Your net earnings show what remains in your pocket after all these deductions. Understanding net earnings helps sellers set fair prices and know if their sales are profitable enough to continue selling items.
How Net Earnings Is Calculated
Formula
Net Earnings = Sale Price − (Sale Price × Selling Fee Rate ÷ 100) − (Sale Price × Payment Processing Fee Rate ÷ 100) − Fixed Fee − Shipping Cost
Where:
- Sale Price = total transaction value received from buyer (USD)
- Selling Fee Rate = platform commission percentage (%)
- Payment Processing Fee Rate = percentage charged for payment handling (%)
- Fixed Fee = flat fee per transaction (USD)
- Shipping Cost = cost absorbed by seller for shipping (USD)
- Net Earnings = final seller payout after all deductions (USD)
The formula works by starting with your full sale price and then subtracting each type of fee one at a time. First, the platform takes its selling fee, which is usually a percent of the sale price. Next, the payment processor takes another small percentage plus a flat fee for handling the transaction. If you pay for shipping yourself, that cost comes out too. Whatever is left after all these subtractions becomes your net earnings. This step-by-step method shows exactly where every dollar goes so you can see the full picture of your profits.
Why Net Earnings Matters
Knowing your net earnings helps you make smarter decisions about pricing and which items to sell. When you understand exactly how much you keep from each sale, you can plan better and avoid losing money without realizing it.
Why Understanding Fees Is Important for Online Sellers
Many new sellers look only at the sale price and forget about all the fees that get taken out. This mistake can lead to unexpected losses. For example, an item sold for $50 might seem profitable until you realize that after an 8% selling fee, nearly 3% processing fee, and $5 in shipping costs, you may keep less than $40. Over time, these hidden costs add up and can turn what looks like a good business into one that loses money. Checking your net earnings before listing items helps you set prices that truly cover your costs and leave room for profit.
For Pricing Strategy
When you know your net earnings formula, you can work backwards to find the right sale price. If you want to earn $90 from an item after all fees, you may need to list it higher than $90 to cover the percentage-based fees. Sellers who use this calculator often find they need to raise prices by 10% to 15% just to meet their income goals. This tool lets you test different prices quickly to see which one gives you the earnings you need.
For High-Volume vs Low-Volume Sellers
The impact of fees changes depending on how much you sell. High-volume sellers who make many sales each day feel the weight of percentage fees more heavily because those fees apply to every single transaction. However, fixed fees like the $0.30 processing charge matter more for low-volume sellers or people who sell low-priced items. Someone selling a $10 item pays a much larger share of that sale in fixed fees compared to someone selling a $500 item. Understanding this difference helps sellers choose which products to offer and whether certain items are worth selling at all.
What Your Effective Fee Rate Score Means
Your effective fee rate shows what portion of your sale price goes toward all fees combined. Look at the table below to see where your result falls and what that range generally indicates for your selling situation.
| Effective Fee Rate Range | Category | What It May Indicate |
|---|---|---|
| Below 10% | Low Fee Burden | Fees take a small share of each sale; easier to profit |
| 10% to 15% | Moderate Fee Burden | Typical range for many online marketplaces; plan accordingly |
| 15% to 20% | Above Average Fee Burden | Fees reduce earnings noticeably; consider raising prices |
| Above 20% | High Fee Burden | Large portion of sales goes to fees; review pricing strategy |
