Quick answer
Net profit per order = price without GST − product cost − shipping − packaging − ad cost per order − payment fee (plus 18% GST on it) − return losses. A ₹999 order at 18% GST leaves ₹847. After ₹515 of costs, a ₹24 gateway fee and ₹10 of average return loss, you keep ₹298, a 35% margin.
How to use this calculator
- Enter your price including GST and the GST rate for your HSN code.
- Add product, shipping, packaging and ad cost per order.
- Add your return rate and the average loss on each return.
Formula
Price without GST = price ÷ (1 + GST rate)
Net profit = price without GST − product − shipping − packaging − ads − payment fee × 1.18 − return rate × loss per return
These results use the numbers you enter. Take costs from your own invoices and reports.
Frequently asked questions
Why is GST taken out first?
GST you collect belongs to the government. Your income is the price without GST.
What is a good net margin for an online store?
Many D2C brands aim for 15–25% net margin after ads. Below 10% leaves little room for returns and price changes.
How do I find ad cost per order?
Divide last month's ad spend by the orders it brought in. Your ad console shows this as cost per purchase.
