# Estimate transaction cost (DEPRECATED)

To measure the cost of a transaction in fiat currency, we calculate as follows

$$
\frac{\text{gas consumed} \times \text{median gas cost} \times \text{tez price}}
{1,000,000} = \text{tx price}
$$

We take as an example the median gas cost**¹**, and the tez price on October 7, 2021:

* median gas cost: 0.1 / gas unit 
* tez price: 6.7

We use the following values for the gas usage: 

$$\begin{array}{l@{\ }c@{\ }l}   \text{tez transfer cost} &=& \frac{1,500 \times 0.1 \times 6.7}{1,000,000} \approx 0.001005\ EUR \\\[2ex] \text{NFT transfer cost} &=& \frac{123,000 \times 0.1 \times 6.7}{1,000,000} \approx 0.08241\ EUR \\\[2ex] \text{Mint NFT cost} &=& \frac{94,000 \times 0.1 \times 6.7}{1,000,000} \approx 0.06298\ EUR \end{array}$$​

* Hic et Nunc NFT minting: [94,000 gas units](https://better-call.dev/mainnet/opg/oopxYaUWMAs8iCG55YVytiuzqCF3AzQ8svZV17cp95vYUQPiVsQ/contents) 
* Hic et Nunc NFT transfer: [123,000 gas units](https://better-call.dev/mainnet/opg/onui6v8SQJUNmPBsmvMaDxiAbBNn8r85pmAifrHWcP2KNRSGvEu/contents) 
* tez transfer: [1,500 gas units](https://tzkt.io/onedAYdnpGG37aDmACc6qiJz1BPTSqPMNBxGwJstwZsNiAPz2D1)

This cost calculation is indicative only. It’s not absolute nor guaranteed; it’s a cost estimate based on figures which are valid at one particular moment.

**\[1]:** We took the median value in a range of 13 gas cost values.
