What does a USDT transfer really cost?

Paste a recipient address to see the Energy, Bandwidth and TRX fee a USDT TRC20 transfer needs, then compare burning TRX with renting Energy.

How TRON fees work

TRON has no gas in the Ethereum sense. It meters two resources instead.

01

Energy

Consumed by smart contract calls. USDT is a contract, so every transfer needs Energy.

02

Bandwidth

Consumed by the raw transaction bytes. Each activated account gets 600 free per day.

03

TRX burn

If an account lacks either resource, the network burns TRX to cover the gap.

# what this calculator does burn = energy × energy_fee + bandwidth × bw_fee rent = energy × rent_price + bandwidth × bw_fee # energy depends on the recipient's USDT balance holder ≈ 64,285 energy new ≈ 130,285 energy
iOS app in preparation

Check TRON fees from your iPhone.

We're building a native iOS app with the same live mainnet calculator, so you can check the cost of a USDT transfer right before you send it.

  • Paste or scan an address and get the fee in seconds
  • Save the addresses you send to most often
  • Read-only and private. No wallet, no keys
Coming soon to theApp Store The iOS app is in preparation. Use the web calculator above in the meantime.

FAQ

Common questions about USDT TRC20 fees.

How much Energy does a USDT TRC20 transfer need?

About 64,285 Energy when the recipient already holds USDT, and about 130,285 when the recipient has a zero balance. Exact usage can shift with contract state and network parameters, so adding a sender address runs a live simulation.

Why does sending USDT burn TRX?

When the sender lacks Energy, the network burns TRX at the current Energy price (100 SUN per unit today). Missing Bandwidth is burned at 1,000 SUN per byte. Every activated account receives 600 free Bandwidth per day.

What is Energy rental?

Accounts that stake TRX generate Energy and can delegate it to other addresses for a fee. Rental prices vary by provider and over time. Enter the price you are quoted in the calculator to compare it with the network burn price. This site does not sell or rent Energy.

Is the result exact?

With only a recipient, the result is an estimate based on that address's current USDT balance. With a sender, we run a read-only simulation of the transfer from that account. On-chain state can still change before you broadcast, so the final cost may differ slightly.

Is it safe to paste my address here?

Yes. The calculator only reads public data from TRON mainnet and never asks for a private key or seed phrase. Never paste those into any website.
