Banks allow you to exchange ores for money at a much higher rate than the bank at spawn. The level of the bank decides the rate of exchange. Banks can be upgraded to a max exchange rate of 170% actual ore value (Level 11). The starting Town Bank is level 1 and will exchange at a 40% rate. So if you were to exchange 1 gold ingot you would receive 80 Coins because 40% of the gold ingot's value (200 Coins) is 80 coins.
Banks are also affected by the Town's global rate.
Banks are cheap to build but can be more costly to upgrade. If you are not a member of the town that the bank is in, you will be required to pay a minimum of 5% non-membership fee. For example, if you were to exchange 1 gold ingot at a Level 1 bank that you were not a member of, you would only get 76 coins due to the 5% non-membership fee. All Bank fees collected go directly to that bank's town treasury. Because of this, being mayor of a town with a high-level bank can be very profitable.
Banks can be affected by buffs like the Trade Goodies Greed and Barter. Obtaining these resources can be a boon both early and late game.
In addition to upgrades for the bank exchange rate, a different set of upgrades is available that will grant your Civilization interest every 24 hours on the coins held in the Civilizationtreasury. Your bank DOES NOT start with this ability, you will have to purchase the upgrade first in order for it to enable interest. You can find the upgrade tree below.
The interest earned daily is calculated based on the "Principal" amount listed in /civ info. It is simple interest, compounded daily.
Interest Earned = Principal * Rate
Your Civilization's principal is determined by the smallest amount of coins in the civ treasury over the previous 24 hours. In essence, when upkeep ticks, your Ciivlizationwill be granted interest based on the smallest principal since upkeep ticked the previous day.
If your Civilization has multiple Towns with Interest Upgrades, it will grab the highest Interest upgrade and calculate it with this.
This is an important concept, because delaying a series of big purchases or an expensive research project until after the current day's upkeep tick will net you a larger interest payout!
You can upgrade your Bank to a higher level. Doing this will allow you exchange your ores at a higher rate
To level up to the next level, your town requires one of the following technologies; Minting, Barter, Guilds, Currency, Banking, Economics, Stock Market and World Trade
