Fuel tech cost here:
Side notes:
- UKF T3 = hammer/anvil
- side tech = weapon/grenade unlocks, OKW T2 repair pioneers
- "full tech" = all tech structures up (usually not the case for SOV, OKW and USF) + side techs (usually no the case for any faction)
- "medium rush" has always chosen the cheapest way to a medium (cheapest tech structure, e.g. OKW T1, and no side tech or medics)
- OKW and OST values: include both the battle phase + building / truck + building cost
There were also previous discussions here:

and here:

And one last note: The best number we want to discuss about is probably the "FU gain for medium tech" and then add some side tech cost for UKF, maybe USF and also maybe 20 FU for OKW because T1 is not meta.
Now, comparisons:
All factions pay rougly the same amount for getting tech for mediums up. UKF pays the least but usually has to side tech to bolster and/or weapon racks to make it through. OKW pays the most. Another side of the medal is MP cost though, and my calcs on that one show that OKW has a huge advantage here until the early-mid game. This results from unlocks like StGs, snares and nades for which they basically pay no MP and that point in the game. This allows them to invest more into infantry and map control and get some of the fuel disadvantage back, depending on player skill. We can conclude that all factions get their medium tech probably within 30 sec to one min in an even game.
After that players need to wait for the FU for their medium tank. If we assume that mediums are at the moment well balances against one another, then there is no problem. OKW has to wait the longest, but gets the best tank (at least for tank on tank warfare), SOV the shortest but get the worst.
All factions pay roughly the same for full tech, while the non vanilla factions pay the most. However, these factions rarely get full tech (all structures plus all side techs) because it rarely makes sense.
