roads are high value in Civ 5 (1 gold upkeep every turn), but I make several of that ago when I connect my cities to mine capital. Is it constantly still a network loss, and if so, is the money much better spent elsewhere beforehand in the game?

There room two an easy reasons to affix your urban by roads: because that Trade path income, and for Unit movement

Connecting for trade Routes

Warning! this calculations are now suspect because of new info found about how roadway maintenance works. I will upgrade this with any changes needed once we have verified numbers for road maintenance costs.

You are watching: Civ 5 roads to city states

Summary: only develop trade routes to cities through 6 populace or more. If you care for the math, then proceed reading...

Now that Oak has solved the Trade route formula because that us, we recognize that typical trade revenue is very close to 1.25 * population of the linked city. (not the capital)

So, mean you have actually your capital and also one city, they room separated by 6 hexes. You"ll be paying to preserve each the those roads, costing girlfriend 6g. So, at a populace of 3, you would make 3.75g, it is in spending 6g, and also be losing money overall. Your worker time is quickly spent act something else. The course, if your cities room closer together, the calculations look better. Finally, I believe that Harbors expense 2g to maintain. Realizing the you just pay for your capital harbor once, sea routes efficiently only cost 2g to maintain.

Population | income | Net earnings with...| Harbor/ | | | 6 roadways | 4 roads | 2 roadways |3 | 3.75g | -2.25g | -.25g | 1.75g |4 | 5.00g | -1.00g | 1.00g | 3.00g |5 | 6.25g | 0.25g | 2.25g | 4.25g |6 | 7.50g | 1.50g | 3.50g | 5.50g |I would prefer to suggest a dominance of thumb. You have the right to pick whichever population number seems best to you, but I think my worker can do far better than also a 4g development by working other tiles in the time it would have actually taken him to construct that road. Thus:

Only develop trade courses to cities through 6 population or more.

If you follow this dominance of thumb, girlfriend will, at the least, never shed money ~ above a profession route. Further, if you begin working top top the profession route as soon as the city is size 6 already, there"s a great chance it will have actually grown to 7 at the very least by the moment you finish, and you deserve to actually begin making sufficient money for that worker time come be precious it.

Final keep in mind on profession routes: Arabia it s okay a flat +1 come trade path income. (AFTER the multiplier, therefore simply add 1 to every yellow number on the chart.) so feel totally free connect Arabian urban at population 5 or more, if girlfriend like.

Connecting for Unit Movement

We don"t have almost as good of data on this, yet from my civilization experiences, roadways are very worth building if friend are developing units and also sending them to war. You get your best units in ~ the front because that longer prior to they room obsolete, and also you"ll have an ext units in ~ the former at any kind of given time.

If you"re not relocating units because that war, roadways may also be worth structure to easily move defenders in the occasion of being attacked, through barbarians or one more Civ. I think you deserve to just ask yourself:

Am I most likely to be assaulted in that city?Is the attack likely come beat the city?Do you have actually units that can get over there by the road to defend?

If any kind of of those that no, the road is not worth it, reason it won"t help.

And if you"re not at war, and not defending, ns doubt you desire to construct roads simply to move units, since you don"t sound choose you"re moving units around much in ~ all!
