I'd like to show you that site: https://bitcoiner.live/

Basically, this is the tool to recommend to newcomers when they ask questions about fees. Existing tools are either too complex with too many numbers or have a tendency to overestimate fees.

Optionally, you can select any of 3 estimation "profiles":

    standard: is the default one and aims to strike a good balance between cost and accuracy.

    optimistic: slightly underestimates if your objective is fee minimization before accuracy. It might work out if the next blocks are pretty lucky, but it might take longer otherwise.

    cautious: on the other hand is pretty greedy, use it only if you really want to be sure to target the next blocks or so even if the next blocks turn out unlucky.
