Energy Estimator

GET 
/calculator/estimate-energy

Find out exactly how much energy a TRC20 transfer will consume before you buy a rental — no guessing, no overpaying. TRONAgg simulates the transfer(address,uint256) call on-chain against live network state and returns the precise energy the transaction would burn, plus the equivalent TRX cost at the current getEnergyFee rate.

Defaults to USDT; pass contract_address to estimate any other TRC20 token.

Why use it

  • Size your energy rental precisely instead of relying on rough averages
  • Compare energy cost across different TRC20 tokens
  • Detect first-time receivers (a brand-new recipient costs ~2x more energy)

Good to know

  • Energy prices move in real time — round the returned value up when placing an order
  • Rate limits: 10 req/min per IP, shared by both estimator endpoints (429), and 60 req/min shared to the TRON node (503)

For a quick USDT-only check, see the USDT shortcut which takes the two addresses straight in the URL.
