Your estimated results
Planning estimate only. Actual fees, taxes, refunds and other business costs can differ.
How to use this calculator
- Enter the selling price and the real variable cost attached to each sale.
- Add marketplace fees, payment-processing fees, advertising cost per sale and a reasonable refund-rate assumption.
- Enter monthly sales and calculate. Change one assumption at a time to see which factor has the biggest effect on profit.
Formula used by the calculator
Profit per realized sale = selling price − product cost − percentage-based fees − advertising cost. Estimated realized sales = monthly sales × (1 − refund rate). Estimated monthly profit = profit per sale × realized sales.
Worked example
| Selling price | $27.00 |
|---|---|
| Product cost per sale | $2.00 |
| Marketplace fee | 6.5% |
| Payment processing | 3.0% |
| Advertising cost per sale | $3.00 |
| Refund rate | 2% |
| Monthly sales | 50 |
With the sample values, combined percentage-based fees are 9.5% of $27.00, or about $2.57 per sale. After the $2.00 product cost and $3.00 advertising cost, estimated profit per realized sale is about $19.44. A 2% refund assumption reduces 50 sales to 49 realized sales, producing an estimated monthly profit of roughly $952 before costs not entered here.
Revenue is not the same as profit
A digital product with strong sales can still disappoint if customer-acquisition cost, marketplace fees or refunds are high. Revenue tells you what customers paid. Profit asks what is left after the costs that matter to the transaction. This calculator brings those assumptions together so you can see both per-sale and monthly effects.
Why profit margin matters
Profit per sale gives you a dollar amount. Profit margin expresses that amount as a percentage of the selling price. Margin makes it easier to compare products at different prices and identify offers that generate revenue but leave little room for overhead, support, software or future advertising.
How advertising changes the result
Advertising cost per sale is one of the fastest ways to change digital-product economics. If your paid acquisition cost rises while price and conversion rate stay the same, profit falls. Use the calculator to find the maximum acquisition cost you are comfortable with before a campaign becomes unattractive.
What refunds do to monthly profit
Refunds reduce the number of sales that ultimately generate revenue. Even a small refund rate can matter when monthly volume grows. The calculator treats the refund rate as a reduction in realized sales so you can see the monthly effect without pretending every order becomes permanent revenue.
Ways to improve a weak result
If the estimated profit is lower than expected, identify the largest cost before changing the price. You may be able to lower acquisition cost, improve conversion rate, reduce avoidable refunds, change sales channels, bundle complementary assets or increase perceived value through better product positioning and branding.

What costs should I include?
Include variable costs that materially affect a sale, such as marketplace fees, payment processing, advertising and any per-sale fulfillment or licensing expense.
Can I use this for PLR products?
Yes. For a PLR-specific ROI view that includes the initial license and rebranding investment, use the PLR Profit Calculator.
Why include refunds?
Refunds reduce the number of sales that ultimately produce revenue, so a realistic refund assumption can improve the monthly estimate.
Is the monthly profit guaranteed?
No. It is a scenario based entirely on the assumptions you enter. Actual sales, fees, refunds and advertising performance can differ.
How often should I update the inputs?
Replace estimates with real costs as soon as you have enough transaction data to calculate realistic averages.
