> A modeled 1,200-transfer merchant flow uses 8,110.2 TRX in Energy, about $2,668 at an Oct. 12 reference price, before Bandwidth and processing costs.

Businesses accepting Tether USD (USDT) on TRON may face network costs after a customer’s payment arrives, because a treasury sweep or payout adds transfers whose Energy use can vary with recipient balances and contract activity.

Energy covers execution of the USDT contract, while Bandwidth covers transaction data. A network check at 9:39:32 a.m. ET (13:39:32 UTC) Oct. 17 set the burn rates at 100 sun for each Energy unit and 1,000 sun for each Bandwidth unit; one TRON (TRX) equals 1 million sun. Bandwidth includes a free allowance of up to 600 units per account over a rolling 24-hour period, limited by the quota remaining. Energy has no free allocation.

Two on-chain USDT transfers in 2026 used different amounts of Energy and each recorded 345 Bandwidth: one on June 9 consumed 64,285 Energy, while another on Sept. 21 used 130,285. At the checked rate, the Energy portion represents 6.43 TRX in the first case and 13.03 TRX in the second. A sender without enough Bandwidth quota would burn another 0.345 TRX to cover all 345 units.

Energy use can change with the recipient’s USDT balance in the token contract; a recipient with no existing balance can require more. That is separate from whether the TRON address is activated, which may involve its own charge. For heavily used contracts, the Dynamic Energy Model can add a penalty of up to 3.4 times base Energy, for a maximum total of 4.4 times base. The multiplier varies with contract activity.

For a direct customer-to-merchant transfer, resource costs generally fall on the sender’s account. A business using separate deposit addresses may pay to sweep funds into a treasury wallet, then incur more resource costs when it sends payouts. The merchant’s total depends on its wallet setup and how often it consolidates deposits.

An illustrative operation assumes 1,000 customer payments, one merchant-funded sweep per deposit and 200 payouts, producing 1,200 transfers paid for by the business. If 1,140 transfers use 64,285 Energy apiece and the remaining 60 use 130,285, combined consumption reaches 81.102 million Energy, or 8,110.2 TRX at the checked rate. Valued at $0.328946 per TRX — the Oct. 12 UTC daily close — that Energy amounts to about $2,668.

The estimate leaves out Bandwidth burns, payment-provider fees and conversion costs, and it assumes a sweep for every payment. A shared treasury address could remove the 1,000 deposit sweeps. Businesses can stake TRX or receive delegated Energy; TRX covers any remaining resource shortfall, while rental prices vary by provider.
