Add your product cost, shipping, fees and ad spend. Every fee rate is editable, so it matches your own account.
- Step 3
Read and copy the result
See profit, margin and break-even with the formula beside them, then copy a summary into your sheet.
Why sellers use these tools
- No fee rates are hardcoded
- Marketplaces change their fees often. You enter the rates from your own seller account, so nothing goes stale.
- Your numbers stay in your browser
- The calculators run on your device. Nothing you type is saved or sent to a server, and there is no account to create.
- Exact decimal arithmetic
- Money is calculated with decimal math, so you never see rounding drift like 0.1 + 0.2 = 0.30000000000000004.
- Built for Pakistan as well
- The Daraz calculator defaults to PKR and includes commission, payment fees, VAT on fees and a return allowance.

Frequently asked questions
Are marketplace fees and commissions hardcoded into these tools?
No. Fee rates for Shopify, Amazon FBA and Daraz are all editable, with placeholder hints only. Always verify your exact fee tier in your own seller dashboard.
Why does decimal math matter for e-commerce calculations?
Standard JavaScript floating-point math introduces rounding drift (0.1 + 0.2 equals 0.30000000000000004). These tools use decimal.js so margins and break-even points are exact, and rounding happens only when a result is displayed.
Do these calculators store or transmit my financial data?
No. All calculators run inside your web browser. Your numbers are not sent to a server and are not saved in a database. The site only remembers your currency and theme choice in your own browser.
How does the currency switcher work?
You can switch between USD ($), GBP (£), EUR (€) and PKR (Rs.) at any time. The switcher changes the symbol and number format only. It does not convert amounts between currencies.
What is the difference between markup and profit margin?
Profit margin is profit as a percentage of the selling price (profit ÷ revenue × 100). Markup is profit as a percentage of your cost (profit ÷ cost × 100). A 100% markup equals a 50% profit margin.
How does the shipping calculator avoid dimensional weight surprises?
Couriers bill whichever is greater: actual weight or dimensional (volumetric) weight. The tool computes both in metric or imperial units with an editable divisor and shows the chargeable weight.
Why is there a separate Daraz calculator?
Daraz is a leading marketplace in Pakistan with its own fee mechanics: category commission, payment handling, VAT on fees and cash-on-delivery returns. The calculator defaults to PKR and lets you enter your own rates.
