Question Gas Line Sizing

I'm working on our remodel plan and some gas changes are needed. My thought was that the gas line sizing would be easy to figure out and I envisioned using an online calculator taking in appliance BTU info and run lengths, but I didn't find anything like that and there seems to be a lot factors that I'm not so interested in digging into. I've attached a diagram of our plan. The current house line I believe is 3/4 and that services the existing furnace, hot water heater and stove. My remodel diagram lists the existing water heater and new stove, but the plan only calls for those lines to be plumbed. Our plan is go electric as much as possible and offset with solar, but we want to keep the gas option alive for the stove and water heater. Each of these lines could be sacrificed to achieve the goal of not upgrading the 3/4 inch service line.

Is there a simple calculator out there that can help me?
Any tips/thoughts on how to best go about the line size calculation?

Would appreciate any help people can provide.
