ADA Fee Calculator: Estimate Your Cardano Transaction Cost

A standard wallet-to-wallet ADA transfer typically costs between 0.17 and 0.18 ADA. Based on current protocol parameters, a 200-byte transaction produces a fee of roughly 0.1642 ADA, while a slightly larger 360-byte transaction comes to about 0.1712 ADA. These figures remain stable unless protocol parameters are updated.

Apply the formula: fee = 0.155381 + (0.000043946 × transaction_size_in_bytes). Estimate your transaction size by counting inputs, outputs, and metadata. Most standard single-input, single-output transfers produce a transaction of 180–220 bytes, giving a fee in the 0.163–0.165 ADA range.

Yes. Smart contract interactions on Cardano include an additional execution budget covering CPU steps and memory units. A complex DeFi transaction can cost anywhere from 0.3 ADA to 0.8 ADA, depending on script complexity. Wallets that support Plutus scripts calculate this fee automatically before you confirm.

The main factors are: number of inputs and outputs (each adds bytes), presence of metadata, number of native tokens included, and whether the transaction involves a Plutus script. Adding more recipients or attaching a message increases size and therefore the fee slightly.

Sending ADA alongside native tokens (NFTs or fungible tokens) increases transaction size due to the extra data required to represent each asset. A transaction carrying several NFTs might be 500–800 bytes, producing fees of 0.177–0.190 ADA for the network component, plus any script execution costs.

Yes. Wallets such as Eternl, Lace, Vespr, Daedalus, and Yoroi all calculate and display the required network fee before you sign a transaction. You only pay the minimum required fee unless you intentionally set a higher amount, which can marginally improve inclusion speed during rare congestion periods.
