Interest

At the end of each round, $1 of interest is earned for every $5 the player has at the end of the round, with a cap of $5 each round (which means that any money over $25 won't generate interest). This incentivizes the player to save money up to a point.

• To the Moon (Earn an extra {{Money|1}} of {{hl|orange|interest}} for every {{Money|5}} you have at end of round Uncommon Economy N/A (Passive) To the Moon.png) gives an extra $1 interest for every $5 held at the end of a round.
• Seed Money (Raise the cap on interest earned in each round to {{Money|10}} Base Seed Money.png) and its upgrade Money Tree (Raise the cap on interest earned in each round to {{Money|20}} Max out the interest per round earnings for ten consecutive rounds Upgraded Money Tree.png) increase the cap on earned interest to $10 and $20 respectively (which means that any money over $50 and $100 won't generate interest respectively). Large amounts of money can be gained per round by combining these vouchers with To the Moon (Earn an extra {{Money|1}} of {{hl|orange|interest}} for every {{Money|5}} you have at end of round Uncommon Economy N/A (Passive) To the Moon.png).
• Any economy Joker and Gold cards can help in getting more money and thus win more interest up to the cap. Note that economy Jokers that trigger once the round is already over (like Golden Joker (Earn {{Money|4}} at end of round Common Economy N/A (Passive) Golden_Joker.png) and Rocket (Earn {{Money|1}} at end of round. Payout increases by {{Money|2}} when [[Blinds|{{hl|orange|Boss Blind}}]] is defeated Uncommon Economy N/A (Passive) Rocket.png)) don't count towards interest that round, whereas Gold Cards ({{money|3}} if this card is held in hand at end of round Gold Card.png) and Jokers that trigger before (like Reserved Parking (Each {{hl|orange|face}} card held in hand has a {{hl|green|1 in 2}} chance to give {{Money|1}} Common Economy On Held Reserved Parking.png)) do count towards interest in the same round.
• Green Deck ( At end of each Round: <br> {{Money|2}} per remaining {{hl|blue|Hand}} <br> {{Money|1}} per remaining {{hl|red|Discard}} <br> Earn no {{hl|orange|Interest}} Discover at least {{hl|orange|75}} items from your [[collection]] Green Deck.png), The Omelette ( ), and Mad World ( ) have the property of not being able to gain Interest, making Seed Money (Raise the cap on interest earned in each round to {{Money|10}} Base Seed Money.png), Money Tree (Raise the cap on interest earned in each round to {{Money|20}} Max out the interest per round earnings for ten consecutive rounds Upgraded Money Tree.png), and To The Moon () useless. Those cards are banned in The Omelette ( ).
• Yellow Deck ( Start with extra {{Money|10}} Discover at least {{hl|orange|50}} items from your [[Collection|collection]] Yellow Deck.png) starts with an extra $10, thus earning $2 of interest in the first round.
