The quickest way to earn money, though perhaps painful, is to save Tower Bux in increments of 50. Then they can be traded at the Bank from the main menu at the best ratio for coins by far.

Exchanging Tower Bux for Coins

When exchanging Tower Bux for Coins in Tiny Tower, consider this: Which exchange is the better long-term investment? For example, should you spend that 1 Tower Bux now and nab 250 coins, or would it be worth more in the future to save up and get 100,000 coins for 50 Bux?

I'll lay it out for you;

Option 1: The cheapest option is the exchange of 1 Tower Bux for 250 coins. Let's represent the words "Tower Bux" as "TB" in an effort to save time. 

250 coins / 1TB = 250 coins. Therefore, 1TB= 250 coins in the first option. It's an OK investment, but as a persistent investor, you can find a better option.

Option 2: The second option is the exchange of 5 Tower Bux for 1,500 coins. That would mean that 1 Tower Bux, or 1TB, equals 300 coins. 

1,500 coins / 5TB = 300 coins, therefore 1TB = 300 coins. The second option would seem to be the better investment, because in Option 2, one Bux equals a whole 50 coins more than in Option 1.

Option 3: Now let's move on to Option 3, which is the exchange of 20 Tower Bux for 20,000 coins. If I do the math;

20,000 coins / 20TB = 1,000 coins, therefore 1TB = 1,000 coins. 

Huge difference, right? That shoots the worth of a Tower Bux up from 300 coins to 1,000 coins, making Option 3 the best investment so far.

Option 4: This final and most costly exchange is 50 Tower Bux for 100,000 coins. Here's the math:

100,000 coins / 50TB = 2,000 TB. Therefore, 1TB equals a whopping 2,000 coins, which would be the obvious best investment. Considering that the original value of a Tower Bux was 250 coins and now it's 2,000 coins, the final value of one Tower Bux is 8 TIMES MORE than the original investment!

If possible, stay persistent and save any Tower Bux possible; Once you reach 50 and trade them in for 100,000 coins, it'll pay off. Greatly. 

Now go out and save some Bux!

Note: When your tower gets really big (90+ floors) it will be a waste of Tower Bux to exchange for coins when you could easily gain more than the amount of coins in a day without spending any Tower Bux.

Elevator Upgrades

Early on in the game, it may be tempting to spend Tower Bux to Hurry or Quick Sell as much as possible, but the real payoff comes in elevator upgrades — before the tower becomes too tall for the player to escort Bitizens efficiently.

Floor Upgrades

Added in Version 1.3.

This section is wrong and needs updating. Floor upgrades add 5 mins to restocking time of each item not 15 as stated, and the impact of having dream jobbers is not factored into profit calcs. The profit per upgrade is 765 coins/ stock-sale cycle with all 3 dream jobs filled, not 315 as stated. It's roughly 8 stock-sell cycles, which for most floors will take under 1 day each cycle (at worst), or a week to 8 days (at worst) to be making extra compared to buying coins. It would appear to be a good investment to upgrade floors, especially where you have dream jobbers for that floor.

At the cost of 3 Tower Bux, the player can permanently upgrade a commercial floor. Each level of upgrade does the following:

• Adds 75 Stock to each product
• Adds 45 Coins to the cost of restocking each product
• Adds 5 minutes to the restocking time of each product

Because patterns of similar cost-stock relationships appear throughout all floors of the game, we can compare the financial efficiency of an upgraded floor to a normal one easily. Note that Cost and Profit are expressed per product:

So as we can see, this doesn't seem to be a particularly lucrative option for spending Bux. However, the casual player (one that checks the game infrequently and therefore often has closed commercial floors), this can be a better investment than trading 50 Bux in for 100,000 coins at the Bank given enough time. 3 Bux is equivalent to 6,000 coins at the best ratio at the Bank, but upgrading a commercial floor increases its fully-stocked income by 315 coins, via:

Therefore, after 20 full restockings, an upgraded floor at about LVL 18 (or ~17 floors each upgraded to LVL 2) will have generated more coins than if those Bux were used at the Bank. However, if the player is vigilant to optimize overlap player and can keep commercial floors open nearly constantly, the amount of time needed to break even become prohibitively long, from the minimum of 15 additional minutes to up to 15 additional hours of playtime.

This strategy is most useful on floors that have a relatively low total number of products and therefore close frequently, such as the Sushi Bar, Pub, Mexican Food, or other low value floors, as the benefit of this strategy is only realized if the upgrade avoids a store closure. Essentially, if a player expects to see commercial floors ever closed for a total 20 times longer than it would have taken to sell the additional 225 stock — which at an average of 10 Bitizens per minute at 100% business demand would take 22.5 minutes — he or she should upgrade those floors rather than saving up the Bux to trade in at the Bank. If the player has no problems keeping their floors stocked and open, they should not invest in upgrades.
