Rs 30,000 if reusing existing home kitchen utensils, up to Rs 55,000-75,000 for a full setup serving 25-30 tiffins/day, per OkCredit's India tiffin-service cost breakdown. This includes vessels (Rs 15,000-20,000), a commercial stove (Rs 8,000-12,000), tiffin boxes (Rs 6,000-10,000) and first-month ration (Rs 15,000-25,000). FSSAI basic registration costs just Rs 100 and is valid without renewal.
An illustrative example from OkCredit's cost breakdown: selling 30 tiffins/day at Rs 80 each (cost Rs 50, margin Rs 30) over 26 working days works out to roughly Rs 62,000 in monthly sales before other expenses -- useful as a benchmark to model your own numbers against, not a guaranteed outcome, since subscriber count, food cost inflation and delivery radius will change the real figure.
