What Is TRON Bandwidth?

Educational article · Updated: October 2026 · Reading time: ~5 minutes

Bandwidth is the simpler of TRON's two resources. Every transaction is just a bundle of bytes that must be stored in a block — and Bandwidth measures exactly that: the size of your transaction data in bytes.

The free daily allowance

Every TRON account with at least a tiny amount of TRX (historically 0.1 TRX, effectively any activated address) receives 600 free Bandwidth points every 24 hours. A typical plain TRX transfer takes about 230–270 bytes, so roughly 2 free transfers per day fit into the free allowance.

Item	Value
Free Bandwidth per account	600 points / day
Typical TRX transfer size	~230–270 bytes
Bandwidth from staking 1 TRX	~1 point (up to 1000 cap)
Refill rate	continuously over 24h

Unused free points do not accumulate beyond the daily cap — you cannot save them up for a busy week.

What happens when you run out

If you spend your free points and have no staked Bandwidth, the network burns 0.001 TRX per byte of your transaction. For a 250-byte transfer that is about 0.25 TRX — small, but not zero, and definitely not "free".

Note: A USDT transfer consumes Bandwidth and Energy. The Bandwidth part is usually trivial (0.25 TRX worst case). The eye-watering 13–27 TRX "fee" people complain about almost always comes from the Energy side. Read our article about TRON Energy for details.

Staking for Bandwidth

Just like with Energy, you can stake TRX to receive Bandwidth. Approximately 1 TRX staked gives 1 Bandwidth point, with a useful cap of about 1,000 points — enough for ~4 free transfers daily. Many users who move funds regularly stake a small amount just to cover the Bandwidth side permanently.

Common Bandwidth questions

Do failed transactions refund Bandwidth?

No. Any transaction that makes it into a block consumes Bandwidth, even if the smart-contract call inside it reverted. This is a general property of blockchains, not a TRON quirk.

Why did my "free" transfer burn TRX?

Three possible reasons: you already used today's free points; your transaction was larger than usual (for example, a token transfer with a long memo); or your wallet chose an execution mode that shifts costs around. Check the transaction on a block explorer to see exactly what was consumed.

Is Bandwidth shared between accounts?

Staked Bandwidth can be delegated to another address, but the 600 free points are strictly per-account.
