Ecommerce Profit Calculator

When selling on an online marketplace in India, there are hidden expenses that most people aren’t aware of until the settlement day.

Marketplace commission, fixed fees, shipping costs, and GST can make it much less than the selling price. 

All in Calculators’ free e-commerce profit calculator is designed to fill that void. You will now see your real net profit and margin.

After all the marketplace deductions, such as Amazon, Flipkart, Meesho, Snapdeal, Myntra, Zepto, Blinkit, Instamart, and more.

There’s no registration to sign up, and the calculator is free, and the results automatically update as you type, so you can test out different price points or categories within seconds instead of having to rebuild the spreadsheet every time.

Why Marketplace Selling Hides Your True Profit

Amazon and Flipkart do not show you the selling price when you enter a product. Marketplaces keep a referral commission based on the category, a closing or fixed fee per order, shipping fees based on weight and destination, and GST on the product and fees. 

On top of that, quick commerce platforms, such as Blinkit, Zepto, and Instamart, have their own commission models.

If the only information a seller has is the cost price versus selling price, he/she may think he/she made a good margin.

Only to discover that the actual settlement price is 15-30 percent less after all of the fees are applied. This is the very thing the calculator aims to eliminate.

How the E-commerce Profit Calculator Works

The calculator asks for a handful of inputs that mirror what you would enter into a seller dashboard:

• Selling price, including tax, in your chosen currency
• Cost of Goods (COGS), what the product costs you to source or produce
• Shipping weight in grams, since marketplace shipping fees are typically weight-based
• Product GST rate, selectable from standard Indian GST slabs (0%, 3%, 5%, 12%, 18%, or 28%)
• GST on fees, since marketplaces charge GST on their own commission and fixed fees as well
• Marketplace and category, which determines the commission percentage applied

When once entered, the calculator processes the numbers and breaks them down, line by line, instead of giving you just one number. 

You’ll see the taxable value, the amount of GST that you paid the government, the amount of commission that you’ll get from the marketplace, the closing or fixed fee, the shipping fee, and the amount of GST that you’ll pay on the shipping fee. 

The total amount of commission that you’ll receive from the marketplace, and finally, the amount of your net profit per unit and the amount of the margin percentage.

The Formulas Behind the Numbers

The calculation follows the same logic a seller would use when reconciling a marketplace settlement report:

Step 1: Taxable Value Taxable Value = Selling Price ÷ (1 + GST Rate)

Step 2: Product GST Payable Product GST = Selling Price − Taxable Value

Step 3: Marketplace Commission Commission = Taxable Value × Category Commission Rate

Step 4: GST on Fees GST on Fees = (Commission + Fixed Fee + Shipping Fee) × GST on Fees Rate

Step 5: Total Marketplace Fees Total Fees = Commission + Fixed Fee + Shipping Fee + GST on Fees

Step 6: Net Profit Net Profit = Selling Price − COGS − Product GST − Total Fees

Step 7: Profit Margin Profit Margin (%) = (Net Profit ÷ Selling Price) × 100

Breaking the calculation into these steps matters because it shows exactly where your money goes.

A seller might assume commission is the biggest cost, when in many categories the combination of shipping fee and GST on fees quietly takes a larger share.

A Practical Example

Say you sell a fashion item on Amazon for ₹999, inclusive of 12% GST.

Your cost of goods is ₹350, and shipping weight puts you in a mid-tier shipping slab.

• Taxable value: ₹999 ÷ 1.12 = ₹892.86
• Product GST: ₹999 − ₹892.86 = ₹106.14
• Commission (assume 17% for fashion): ₹892.86 × 0.17 = ₹151.79
• Fixed/closing fee: a flat amount set by the marketplace for the price tier
• Shipping fee: based on weight slab
• GST on fees (18%): applied to commission, fixed fee, and shipping combined
• Net profit: Selling price minus COGS, product GST, and total marketplace fees

When all the fees are added up, a ₹649 gross margin may end up being a ₹250 to ₹350 net profit margin, depending on the fixed fee and shipping slab. 

This is why it is crucial to check the actual number before listing a product instead of at the end of the first month of sale, thus avoiding any pricing errors that cannot be corrected. 

Who This Calculator Is Built For

Amazon and Flipkart sellers use it to check category commission impact before setting a price, since commission rates vary significantly across categories like electronics, fashion, and beauty.

Meesho and Snapdeal sellers rely on it to account for lower-margin, high-volume pricing models where even small fee differences affect viability at scale.

Myntra sellers use it to factor in fashion-specific commission slabs, which tend to run higher than general categories.

Quick commerce sellers on Blinkit, Zepto, and Instamart use it to model thinner, faster-turnover margins where fixed fees and delivery costs carry more weight relative to the sale price.

New sellers use it before their first listing goes live to understand how GST, commission, and shipping combine before committing to a price point.

Getting the Most Accurate Results

Commission and fee rates in this calculator are approximate average rates per marketplace and category. Please note that actual rates may differ and are available on your seller dashboard. 

The same product on multiple marketplace tabs also helps determine which marketplace platform actually provides the best net margin, not just selling prices that are higher.

Frequently Asked Questions

Q1: Which markets is this calculator available for? 

This calculator includes Amazon, Flipkart, Meesho, Snapdeal, Myntra, Zepto, Blinkit, and Instamart, and the commission rates have been customized for each platform and product category.

Q2: Is there a calculator that shows GST? 

Yes. It applies the GST according to the standard Indian slabs (0%, 3%, 5%, 12%, 18%, 28%) to the product itself and separately calculates GST charged on the marketplace fees (which also apply in a typical settlement).

Q3: What is going wrong with my net profit that it is not what I thought it was? 

This normally occurs when shipping costs and GST on shipping are not being taken into account.

Many sellers only include the commission and cost price in their calculations of margin, but they forget that the fee level GST also eats into the settlement.

Q4: Is my account’s default commission rates correct? 

These are standard estimates based on the published fee profiles in the marketplaces.

You can check your seller dashboard for actual rates, as they can vary depending on your seller tier, category approval, and any special program participation.

Q5: Do quick commerce apps like Blinkit or Zepto accept this calculator? 

Yes. The fee structures of quick commerce platforms are in there as well, but the fixed fees and commission rates may vary from marketplace to marketplace.

So margins should be calculated independently for every sales channel that offers quick commerce.
