Most households look only at the ₹250 or ₹500 "cable charge" on their bank receipt. The larger bite is usually in the exchange rate: authorised dealers publish telegraphic-transfer rates that embed a spread against an interbank reference. Add 18% GST on the explicit service charge, occasional SWIFT correspondent deductions, and — for larger annual outflows — Tax Collected at Source under the Liberalised Remittance Scheme, and the all-in bite can be multiple percentage points of the principal. That is why remittance cost comparison exercises should always separate the forex markup, SWIFT fees, and GST on charges from the face-value ticket charge.
The Liberalised Remittance Schemelets resident individuals send current and capital account transactions abroad up to a dollar ceiling each financial year, provided documentation and purpose codes are genuine. Breaching the cap or mis-declaring reason codes invites regulatory friction — your bank is required to file purpose on an A2 declaration and withhold TCS where statute mandates. From FY 2025-26 modelling conversations we anchor to a ₹10 lakh cumulative threshold illustration for many purposes before incremental TCS applies, with specific carve-outs such as qualifying education loans routed under Section 80E. Tour package flows may follow a different schedule — your authorised dealer's rule sheet prevails.
Wise vs bank SWIFT is not a religion; it is plumbing. SWIFT strings can be mandatory for certain counterparties, but when local payout networks exist, a specialist may bypass correspondent chains and quote closer to mid-market with an explicit variable fee. Banks still win on familiarity, multi-product relationships, and LRS documentation comfort — but numerically, a 1.5% spread on ₹10 lakh is ₹15,000, far above a ₹500 flat label.
Western Union-style cash networks trade away rate for reach. Remitly Express vs Economy trades time for tariff. BookMyForex-style desks can add value when you want a documented lock-in for large tickets and same-bank comfort. Choose after modelling three numbers: foreign currency received, rupee fee stack, and statutory TCS reservation.
Worked illustration: ₹10,00,000 to the United States at a mid benchmark of 84.2 INR/USD delivers about $11,876 before any markup. If an institution clips 2.2% via spread and charges, you forfeit roughly ₹22,000 versus a 1.0% stack — about ₹12,000 delta on a single leg. Twelve monthly education wires magnify that gap into serious school-fee money, which is why comparing cheapest way to send money from India abroad headlines miss the point unless they expose LRS remittance mechanics honestly.
Minimise cost legally by lining up documentation once, batching transfers only when rate and liquidity align, using purpose codes that match reality, comparing ALL-IN rupee loss not posted fees, and talking to both your bank and at least one transparent digital channel before large tickets.
