How to Calculate Transaction Fees on the TRON Network?

When sending USDT on the TRON network, users see only the final fee amount in the wallet and do not always understand where this fee comes from. The fee is formed from the consumption of network resources, and its size can be optimized if you buy energy in advance at a favorable price.

The FeeSaver service allows you to buy TRON energy taking into account your volumes and transaction frequency, which reduces the actual fee for USDT TRC-20 transactions and makes it more predictable.

How much does a USDT TRC-20 transfer cost

If we rely on average annual values, the picture for fees looks as follows:

• The base fee for sending USDT TRC-20 directly from a wallet without resource optimization is usually in the range of about 7–14 TRX (around 1.86–3.72 USD);
• when using FeeSaver, the average fee for the same transaction is about 2–5 TRX (around 0.50–1.50 USD).

The resulting saving on the fee for a standard USDT TRC-20 transaction can reach up to 60–80%, depending on the specific scenario and network load.

FeeSaver also has a Smart Mode, in which you do not need to think about how much energy is required to make a transaction and whether it is available: the service will do everything for you.

What the fee on the TRON network consists of

There is no single fixed cost per transaction in TRON. The fee consists of two types of resources:

• Bandwidth is responsible for placing and transmitting transaction data in the blockchain;
• Energy is consumed when executing smart contracts.

The more data is processed and the more complex the smart contract logic is, the more of these resources are required. If an address has its own supply of Bandwidth and Energy, a transaction can go through with minimal deductions. If there are no resources or they are exhausted, the network compensates for the lack by burning TRX, and this is where the actual fee that you see in the wallet comes from.

Bandwidth

Bandwidth is a value that is almost always the same, but depends on the transaction size. 1 byte = 1 Bandwidth. This means that if a transaction weighs 345 bytes, it needs 345 Bandwidth to be sent.

The transaction size depends on the size of the following components:

1. Main transaction header: ~100 bytes;
2. Raw data: 68 bytes;
3. Signature and metadata: ~170–180 bytes.

The total size is about 340–350 bytes, for which around 340–350 Bandwidth is required.

Energy

Energy is a dynamic value that can change depending on the parameters of working with the smart contract.

The USDT smart contract call (TRC-20 Transfer) uses energy for:

1. Reading the sender balance: ~200 Energy;
2. Reading the recipient balance: ~200 Energy;
3. Subtracting and adding to the balance: ~200 Energy;
4. Writing the recipient balance: ~20–25k Energy;
5. Writing the sender balance: ~20–25k Energy;
6. Checks: ~300 Energy;
7. Logging the event: ~10–12k Energy;
8. Other system calls, GAS, ADDRESS, CALL etc.: ~1k Energy.

Taking into account that operations may differ in complexity and volume, the average cost of executing the smart contract is about 64–65k Energy. It should also be added that if the recipient address does not have USDT on its balance, then about an additional 64k Energy is spent to perform the operation, which forms a total of 130–131k Energy for such an operation.

How FeeSaver helps reduce the fee on the TRON network

The key idea is simple: instead of paying the full cost of energy through TRX burning every time, you can buy TRON energy in advance at a favorable price through a specialized service.

FeeSaver:

• specializes in selling and renting TRON energy;
• offers pricing based on typical energy consumption for 1–2 USDT TRC-20 transactions (for example, 65,000 or 131,000 Energy for a fixed amount of TRX);
• selects conditions based on your volumes and transaction frequency, from rare operations to a constant transaction flow.

The basic idea of the pricing plans is the following: you pay a clearly defined fixed amount in TRX, receive the required amount of energy and use it for USDT TRC-20 transfers. At the same time:

• without any optimization, when paying the fee directly from the wallet, the average range for one transaction is about 7–14 TRX (1.86–3.72 USD);
• when buying energy through FeeSaver, the average range for the same transaction is about 2–5 TRX (0.50–1.50 USD).

For businesses and users with large transaction volumes, the conditions can be further customized, and the cost of energy and the actual fee depend on the transaction frequency, the number of addresses and the total monthly volume. This is directly indicated both on the pricing page and in the description of the FeeSaver service.

Conclusion

The structure of transactions on the TRON network is quite complex and consists of many parts. In this article we tried to explain which resources are used in transactions and what they are backed by, and also to show how you can simplify your work by using our service. We hope that this material was useful for you and that you now better understand the processes taking place in the TRON network.
