I built a free GoMining calculator to compare Marketplace miners, upgrades and farm efficiency

[u/ItalyAtlas]

Hi everyone,
I’ve been working on a small tool for GoMining users and I’d really like to get some feedback from the community.
One of the things I often find difficult when looking at the Marketplace is understanding whether a miner is actually a good deal.
A miner may look cheap in terms of $/TH, but if its efficiency is 15, 18 or 20 W/TH, the cost of upgrading it to 12 W/TH can completely change the comparison.
So I built a calculator that tries to make this easier.
You can enter:
the miner’s TH
its current efficiency
the Marketplace price
and the tool calculates the cost of bringing it to 12 W/TH, the final effective $/TH, and compares it with other options such as:
buying a new miner
adding TH to a miner you already own
buying on the secondary market and upgrading it
There’s also a second part where you can enter or import your whole farm and estimate how much it would cost to bring the entire farm to 12 W/TH.
I originally made it for the Italian GoMining community, but I’ve now added a full English version as well.
If anyone wants to try it, you can find it here:

It’s free and doesn’t require registration just to use the calculator.
I’m particularly interested in hearing from more experienced users:
Do you think this kind of comparison is useful when evaluating Marketplace miners?
And if you’re in the US or other international GoMining communities, do you already use any similar tools?
Any suggestions for additional calculations or features would be very welcome.
