Profit/Loss Calculator: Check Margins Before You Commit
A profit and loss calculator tells you if a deal is worth it before you sign. Enter cost price, selling price, quantity, and fees to get instant profit, loss, and margin percentages.
Use it to avoid underquoting, plan promotions, and communicate breakeven points clearly with stakeholders.
What This Calculator Delivers
- Absolute profit or loss plus percentage margin
- Breakeven selling price based on your cost and fees
- Scenario comparison: retail, wholesale, or promo pricing
- Optional add-ons: shipping, platform fees, taxes, and discounts
How to Use It
- Enter cost price and selling price for the item or service
- Add quantity to scale totals for bulk orders
- Include variable costs like shipping, packaging, commissions, or payment gateway fees
- Apply taxes or discounts to see the real landed margin
- Review profit/loss output and breakeven suggestions before finalizing the quote
Where It Helps
Ecommerce and Marketplaces
Factor in platform fees and returns risk to see if a discount campaign still meets your margin targets.
Wholesale and B2B Deals
Evaluate tiered pricing or MOQs and decide which volume breaks to offer without eroding profitability.
Services and Projects
Include subcontractor costs, software seats, or travel so your service quotes stay profitable.
Tips for Accurate Margins
- Separate fixed and variable costs; variable costs often scale with quantity
- Account for payment gateway fees and expected returns or refunds
- Use conservative estimates for discounts during sales to avoid surprises
- Revisit breakeven when input costs change (raw materials, freight, FX)
Conclusion
A profit/loss calculator prevents guesswork. By modeling true landed cost and margin before you commit, you protect cash flow and keep promotions strategic instead of reactive.
