About this tool

Pricing mistakes often come from mixing up margin and markup, or from working out margin on a GST-inclusive price. A product that costs ₹500 and sells for ₹650 including 18% GST earns far less than it seems once GST, fees and shipping come out.

The calculator has two modes. Find my price takes your product cost and target margin and works backwards to the selling price including GST, after any percentage or fixed fees, shipping, ad cost per unit and other costs. Check my margin takes a selling price you already have and shows the profit, margin and markup. Both modes show the break-even price and a full breakdown. GST rates follow the slabs in force since 22 September 2025: 0%, 5%, 18% and 40%, plus special rates of 3% and 0.25%.

Margin is profit as a share of the price excluding GST; markup is profit as a share of cost. Costs are entered excluding GST because registered businesses usually claim input tax credit. Marketplace fees carry their own GST and TCS, so check your settlement reports. This is a planning aid, not tax advice; confirm the rate for your HSN or SAC code.

How to use it

Choose Find my price or Check my margin.
Select the GST rate for your product's HSN or SAC code.
Enter your product cost excluding GST and your target margin or current price.
Add marketplace or payment fees, shipping, ad cost per unit and other costs.
Read the price, profit, margin, markup and break-even price.

How it works

Selling price: Including GST, for your target margin after all costs.
GST: The tax collected and the price excluding GST.
Profit: Per unit after fees, shipping, ads and other costs.
Margin and markup: Profit as a share of price and as a share of cost.
Break-even price: The lowest GST-inclusive price that does not lose money.

Formula and assumptionsPrice excl. GST = price ÷ (1 + GST rate). Fees = price incl. GST × fee % + fixed fee. Profit = price excl. GST − (cost + fees + shipping + ads + other). Margin = profit ÷ price excl. GST. Markup = profit ÷ cost. Find my price solves price excl. GST × (1 − margin) − fee % × price excl. GST × (1 + GST rate) = cost + fixed fee + shipping + ads + other.

FAQ

Questions about this tool.

01 What is the difference between margin and markup?

Margin is profit divided by the selling price (excluding GST here). Markup is profit divided by cost. A 30% margin equals about a 43% markup, so the two are easy to confuse.

02 Which GST rates can I choose?

Since 22 September 2025 the main slabs are 5% and 18%, with 40% for specified luxury and demerit goods, nil for exempt items, and special rates such as 3% and 0.25%. Always confirm the rate for your HSN or SAC code.

03 Why are costs entered without GST?

Registered businesses usually claim input tax credit on purchases, so GST on costs is not a real cost. If you cannot claim it, enter costs including GST.

04 Does it include marketplace TCS?

No. TCS and GST on marketplace fees vary by platform and are usually adjusted in settlements and returns. Use the fixed or percentage fee fields to approximate them.

05 Is this tax advice?

No. It is a planning calculator. Check rates and treatment with your accountant or the GST portal.
