Why is actual marketplace seller payout lower than calculator estimates?

Standard calculators fail to account for courier weight discrepancies, 18% GST on platform service fees, TCS/TDS withholdings, and return logistics (RTO). SellerLeak computes the exact net payout based on 2026 published rate cards.

How does RTO impact e-commerce net profitability?

When an order returns undelivered (RTO), forward freight, reverse handling, and packaging costs are absorbed by the merchant with zero revenue. An RTO rate of 20% can eliminate an apparent 25% gross product margin.
