Formula Used
- Total Purchase Cost = (Purchase Price per Unit × Quantity) + Purchase Fees
- Gross Sale Value = Selling Price per Unit × Quantity
- Net Sale Proceeds = Gross Sale Value − Selling Fees + Additional Income
- Gross Gain/Loss = Net Sale Proceeds − Total Purchase Cost
- Tax Amount = Max(Gross Gain/Loss, 0) × Tax Rate ÷ 100
- Net Gain/Loss = Gross Gain/Loss − Tax Amount
- Return Percentage = (Net Gain/Loss ÷ Total Purchase Cost) × 100
- Break-even Sale Price per Unit = (Total Purchase Cost + Selling Fees − Additional Income) ÷ Quantity

Frequently Asked Questions
1. What does this calculator measure?
It measures the full transaction outcome using purchase cost, selling value, fees, extra income, taxes, net gain or loss, return percentage, and break-even price.
2. Does tax apply when there is a loss?
No. This version applies tax only when the gross result is positive. Negative results are treated as losses without adding tax charges.
3. Can I use this for stocks or trading items?
Yes. It works for shares, inventory items, resale products, digital assets, and similar cases where unit cost and selling price determine gain or loss.
4. Why is the break-even price useful?
The break-even price shows the minimum sale price per unit needed to recover total purchase cost, selling fees, and any income adjustments.
5. What is additional income for?
Use it for rebates, bonuses, dividends, side credits, or any extra amount that increases your final proceeds beyond the direct selling value.
6. What is the difference between gross and net gain?
Gross gain compares proceeds and cost before tax. Net gain subtracts tax from the positive gross amount, giving the final usable result.
7. Can I export the results?
Yes. After calculation, use the CSV button for spreadsheet-friendly data or the PDF button for a printable summary report.
8. Why do I see a negative return percentage?
A negative return percentage means your final net result is below the total purchase cost. It signals an overall loss on the transaction.
