Upgrading gold mines not worth it?

I'm currently TVL 6. While I understand the waiting around is a big complaint in this game, is it just me or is the way the gold mine upgrading set up make it almost worthless after a while?

With troop and defense upgrades, you see a somewhat consistent percentage increase (@20%) in their abilities even as you go higher.

However, the gold mines (elixir pumps too) stay at only 300 per hour increase which gets you diminishing returns. For example.....If I look at upgrading a lvl 9 gold mine it will increase production from 2200 to 2500 per hour. This will take a builder 4 days to complete. So, I'm out of production for 4 days x 24 hours x 2200. Once completed, it will take me 29.33 days at the new production rate just to catch up!!!

either I failed math or that just seems ridiculous to me. I'm sure this has been mentioned before so my apologies but I couldn't find a thread on it. Thanks.

Its actually 3.5 days.

4 days * 24 hours* 2200 all divided by 2500*24 hours.

(4*24*2200)/(24*2500)=3.52

I'm confused very confused......

No genius. It's the difference between the old rate and the new rate that is relevant for calculating time to profitability. Since if you didn't upgrade you'd still be making gold at the old rate.

The OP is right. It takes 29 days 8 hours to make a profit from upgrading from level 9 to 10.

When you upgrade a mine or a pump it doesn't produce while it is being upgraded. That means you have to wait a certain amount of time before the upgraded mine or pump makes the amount you would have had if you didn't have it out of commission.

In this case when you upgrade from level 9 to 10 you have to wait 4d. That means you lose 4 days x 24 hours per day x 2200 per hour = 211200.

The new rate is 2500 an hour. Since you would've been making 2200 an hour before, you have to take the difference of the two rates and divide the amount you lost by it to see how long you will take to profit.

So...That's 211200/(2500-2200) = 704 hours = 29 days 8 hours.

Just do them don't worry about it

Upgrading your mines & pumps are DEFINITELY worth it! :D

I lose on average 100k of each resource every time I get attacked - you win some, you lose some - but with 6 lvl 9 mines and 6 lvl 9 elixir pumps, I get it all back when I log back on 12 hours later. Which means I always have enough to raise an army. It's a drag to upgrade, but once it's done, it's done.

So I guess you are saying that you don't intend an playing this game for more than 29.33 days? I have been playing this game for 3 months and even now I know that I will be playing for at least 3 more months (unless Supercell continues on this path it's on, where they are making the game impossible to play without gems).
So unless you plan on quitting before 29.3 days then your post is pointless!

Eventually it's worth it, but the time-scales are ridiculous!

You build a new one from scratch to now lvl 11 and it takes a total of 22641 minutes, or getting on for 16 days.
It then takes 91 days to become profitable.

That's for a single mine or pump!

You equate builders into that by that you'd probably only be using one on mines/pumps whilst other(s) did def or other buildings, and we're talking 16*6 = 96 days total build time, The time til profit would be less than 91 * 6, because you'd already have the previous ones producing, but we're still talking best part of a year!

That's one hell of a commitment!

It should be scaled, so that each upgrade adds a bit extra each time..seeing as they are costing more.
So instead of an increase of 300 each time, it should be 300 for one, 350 for the next, 400 etc...
