Average cost of transfers in Thailand

Personally, I dislike planning a budget for trips the most. It makes me very sad to think that I might not have enough money for entertainment, as I don't earn enough to be able to ignore my expenses. Before looking at the prices on GetTransfer https://gettransfer.com/en/directions/thailand , I googled it and found that I should expect to pay between 800 and 1,500 baht. How reliable is this information? I decided to use their calculator, and it showed me that from Bangkok Airport to Amara Bangkok Hotel, I would have to pay $23 or 715 baht, which was even a little cheaper than I had originally expected. What can you say about the average cost of a transfer in Thailand?
