Seller Calculators

Calculate your real profit per order after marketplace commission, fixed fees, shipping and the tax charged on fees (GST/VAT).

✓No login✓No file storage✓Instant & free

Three calculators every online seller needs. Marketplace Profit shows your true per-order profit: it deducts commission, fixed/closing fees, shipping, and the GST/VAT charged on those fees (18% in India, your local rate elsewhere), then shows your settlement and margin in a transparent line-by-line breakdown. The Tax calculator adds GST/VAT to a base price or extracts it from an inclusive one — any rate, with the CGST/SGST split shown for Indian rupees. Margin & ROI converts cost and selling price into margin, markup and return on investment.

How it works

  1. Pick a calculator: Marketplace Profit, GST, or Margin & ROI.
  2. Enter your numbers — results update live as you type.
  3. Read the line-by-line breakdown to see exactly where money goes.

Frequently asked questions

Why is my settlement lower than price minus commission?

Because marketplaces charge GST (typically 18%) on their fees, and add fixed/closing and shipping fees. The breakdown shows each deduction separately so nothing is hidden.

Does it know each marketplace's exact fee structure?

Fees vary by category, price band and seller tier, and change often — so you enter your commission % and fees, and the math is transparent. Cross-check one order against your settlement sheet to calibrate.

What is the difference between margin and markup?

Margin is profit as a % of selling price; markup is profit as a % of cost. The Margin & ROI tab shows both, plus ROI.

Is anything uploaded?

No — pure in-browser arithmetic.
