Frequently asked questions
How is net profit calculated?
Tax is separated from the selling price if it is included; commission, shipping, product cost and other costs are subtracted. What remains is the net profit per product before income tax.
How does tax affect profit?
Tax included in the price goes to the government. In price-inclusive systems (VAT, GST) the tax on your costs is credited back; with sales tax added on top it is not. If your tax rules differ, change the rate and the "Tax included" switch.
What is the break-even price?
It is the lowest selling price at which you do not lose money. The marker on the slider shows it; below it you lose money on each product.
Are the results exact?
No, they are an estimate based on the values you enter and are calculated before income tax. Ask your accountant for exact tax figures.
Is the information I enter stored?
No. The calculation runs in your browser; none of the values you enter is sent to a server or saved.
