The term 'TRX gas fee' is commonly used to describe TRON network transaction costs, though technically TRON does not use a gas model. Instead, fees are denominated in SUN — the smallest unit of TRX (1 TRX = 1,000,000 SUN). Bandwidth costs 1,000 SUN per byte, and Energy costs 210 SUN per unit at the current network parameter. A standard 268-byte TRX transfer therefore costs 268,000 SUN (0.268 TRX) if paid in bandwidth, or nothing if within the free daily quota. At a TRX price of approximately $0.30, this equates to roughly $0.08 for a bandwidth-paid transfer.

For TRC20 USDT transfers — the most common use case on TRON — the effective 'gas fee' is significantly higher because smart contract execution consumes Energy. At 210 SUN per energy unit and 32,000 energy for a standard USDT transfer, the total energy cost is 6,720,000 SUN or 6.72 TRX (approximately $2.00 at current prices). Add the bandwidth component (345 points × 1,000 SUN = 345,000 SUN) and the total fee lands at around 7.07 TRX without energy optimization. TRON fee proposals in 2025–2026 have debated reducing the energy unit price from 210 SUN to 100 SUN, which would cut fees roughly in half.
