Whereas some video games give you a Wallet of Holding in which you can eventually stash more money than you ever could use, other games aren't so generous about letting you have the money you need to buy that really useful item, no matter how good you are at beating the coins out of Money Spiders. When there are useful items on sale for more than your standard wallet can hold, you need a Wallet Upgrade, which can be any sort of item (which you may have to buy at no small cost) or even an in-game event that raises the amount of money you can carry on yourself.

- In Golvellius, Bibles increase the maximum amount of gold Kelesis can carry.
- Most later games in The Legend of Zelda series have wallet upgrades that let Link carry more rupees.
- The Guardian Legend has Red Landers.
- In Hype The Time Quest, not only can Hype have a wallet upgrade by completing Wellet's race during the Second Era, he can also upgrade the maximum amounds of each good he can carry once through the game, usually by completing a race or getting rids of all the bees plaguing either Torras or the forest.
- In BioShock 2, researching thuggish splicers can increase your wallet cap from $600 to $800. Subverted by way of Missing Secret in the first game, which has a four-digit display for your money despite being immutably capped at $500.

- Drip Stat, an MMO Idle Game to advertise the DripStat Java server monitoring tool, initially limits the player to five "bytes" (clicks) of capacity. Clicking produces no effect after this point. The "Drip" button exchanges bytes in the bank for bytes of capacity: clicking Drip with 3 bytes clears the bank to 0 but adds 3 bytes to capacity. During the tutorial, the capacity quickly doubles to 10, then 20, then 40, until the tutorial ends around 160.
