Use the receipt’s actual values
Ethereum’s gas documentation distinguishes the amount of computation from its price. For an ordinary execution fee, multiply gas used by the effective gas price. If that price is in gwei, divide the product by one billion to express it in ETH.
Use the receipt for a completed transaction. A gas limit or maximum fee setting describes a bound, not necessarily what the sender finally paid. Additional transaction-specific charges can matter in other transaction types or on layer 2 networks.
Try a worked example
For an illustrative transaction using 21,000 gas at an effective price of 20 gwei, multiply 21,000 by 20. The result is 420,000 gwei. Divide by 1,000,000,000 to obtain 0.00042 ETH.
This is an arithmetic example, not a live quote or a prediction about your next transfer. A contract interaction may use a different amount of gas. The rate may also differ by the time a transaction is included.
21,000 × 20 ÷ 1,000,000,000 = 0.00042 ETH.
Record a USD estimate carefully
If you want a dollar estimate, multiply the ETH fee by a clearly labeled ETH/USD price. Keep the native fee as the primary recorded value. Today’s price produces a current equivalent, not automatically the historical transaction-time cost.
In Skooby, the transaction evidence panel gives you the provider’s native fee and an explorer link. Compare the reported fee with the receipt before using it in a report. When values differ, check gas-price units, the network, and whether the number is an estimate or a settled result.
- Record gas used and effective gas price from the receipt.
- Confirm whether the price is shown in wei or gwei.
- Calculate the fee in ETH and compare it with the explorer.
- Add a separate USD estimate only if you can label its price source and timestamp.
