How to calculate true profit per sale
Add up every variable cost — product, packaging, shipping, ads, and marketplace fees — then subtract it from the selling price. Percentage-based fees are the most commonly forgotten cost.
The profit calculator does this in one step and also shows your break-even price.
Why margin and markup are not the same
Margin is profit divided by selling price. Markup is profit divided by cost. A 50% markup is only a 33.3% margin — mixing them up is one of the most expensive pricing mistakes sellers make.
When a discount still leaves a profit
A discount eats directly into margin. If your margin is 20% and you offer a 15% discount, you may drop below break-even once fees are added back. Run the numbers with the discount calculator before launching a sale.
Frequently asked questions
Are these tools really free?
Yes. Every tool on GoSoping is free to use with no account, no sign-up, and no usage limits.
Do you store the numbers I enter?
No. All calculations happen inside your browser with JavaScript. Nothing is sent to a server, and nothing is stored.
Which currency do the tools use?
Results are formatted in Indian Rupees (₹) by default. The math works in any currency — just read the numbers as your local currency.
Can I use the tools on my phone?
Yes. The site is mobile-first and works on any modern Android or iOS browser.
Is the product description generator AI-powered?
No. It's a template-based generator that combines your inputs with reusable copywriting patterns. It never calls an external AI service and never sends your data anywhere.
