Case World Copy the bank UI, then plan around it

The Case World bank is the quiet mechanic that still works after you close Roblox. You deposit valuables, the live UI shows whatever interest language Volatile Industries shipped, and that process can continue while you are offline. This page is a planning worksheet, not a calculator with a secret percent. If you came here looking for a number to paste into a spreadsheet, open the bank screen instead. If the screen shows a rate, a timer, or a projected payout, that is your number. If it shows none of those, you cannot honestly forecast a payout, and the worksheet still helps: it stops you from dueling the pile you meant to park.

Read this beside the sibling code level checklist and the full bank guide. Codes print cash. The bank keeps the part of net worth that should not be cash. Together they are how a 5 January 2026 unboxing room becomes a next-morning pile instead of a 40-player cautionary tale.

Where to read the live numbers

Before you fill any table, stand in front of the bank UI and write only what it labels:

• What you can deposit. If an item is rejected, it cannot earn the offline part of the loop. Sort it with the item list instead of arguing with the teller.
• What is already deposited. First copies you would miss belong here. Duplicates can usually convert.
• Any interest, rate, timer, or projection the panel prints. Copy the text exactly. Do not round it into a “pretty” percent you saw in chat. This wiki will not replace that text with a formula of our own.
• Your cash on the HUD. Cash is the fuel you are tempted to spend the moment a duel invite appears. The worksheet needs that number so you can see when the fuel is too low.

If a friend quotes an interest percent that is not on your screen, they are not a source. They are a rumour. The 30 August 2026 window made the Upgrader and Admin Abuse famous; it did not authorize fan wikis to publish bank math. There is no Trello of rates. There is a panel.

Worksheet one: the nightly plan

Copy this table into notes, then fill it from the live UI. Empty cells are expected. Do not invent fillers.

Field	Where you read it	What you write tonight
Cash on HUD	Top of the Case World HUD
Value or count of banked items	Bank screen
Interest / rate / projection text	Bank screen, copied verbatim
Hours you will be offline	Your clock, not the game
Duel stake you might take	Duels UI
Cash you refuse to spend	Personal rule
Next code level you still need	Code gates

How to use the row without a fake formula:

• If the bank prints a projection, that projection is the plan. Your only job is to not spend the deposit that projection assumes.
• If the bank prints a rate and a time unit, you may apply that rate to the hours you will be gone using ordinary arithmetic you already know. We still will not write “the rate is X.” X is on the panel.
• If the bank prints neither, your plan is qualitative: “deposit keepers, keep a cash buffer, log off.” That plan is valid. It is more valid than a made-up percent.

After an Admin Abuse dump, fill the table again. Extra cases and cash make people skip the bank because the lobby feels rich. That is the night interest mattered most.

Worksheet two: bank vs shop vs duel

A second table stops the Upgrader and the duel booth from silently taxing the first table.

Temptation	Live cost you copy	Healthier alternative
One more paid crate	Shop price	Free case or an A crate from the case ranking
Two crates at once	Shop price x pair	Join group perks first, then buy a pair you already budgeted
Upgrader click	Upgrader UI cost	Fresh crate if cheaper; see upgrader
Duel stake	Duels UI	Only with a duplicate already banked; see duels
Ollypro Jester / capsule	Shop or code grant	Bank first Jester copy; convert extra stickers
Chasing the board	Leaderboard position	Ignore rank until the nightly table is filled

Fill the middle column from the UI every time. The right column is policy. Policy is how you avoid treating virtual items as a casino you owe.

Offline hours are part of the tool

Interest that continues while you are offline is the reason this page exists. You do not have to babysit a 40-player server for the bank to work. You do have to deposit before you leave. A common failure is converting everything to cash “so it is ready,” then logging off with a full HUD and an empty vault. Cash does not earn the bank’s offline part. Keepers do, if the UI accepts them.

Practical rules that do not require a percent:

• Deposit before you redeem a late-night code binge, or you will open the grant and forget to walk back to the vault.
• Deposit before you hop servers looking for an event. Hopping is how people lose track of a first copy in inventory.
• Deposit before you read scripts. A tool that auto-opens cannot auto-regret.
• Deposit even when the projection looks small. Small and real beats large and fictional.

Items remain virtual with no real-world value. A full worksheet does not make a rifle sellable outside Roblox. It makes the leaderboard less of a yo-yo.

Worked example with blanks (on purpose)

Suppose your HUD shows some cash, the bank holds a first-copy weapon-style skin, and the panel prints a projection. You write the projection into row three. You will be gone eight hours. You do not multiply by a wiki percent. You either trust the projection or you do not play the forecast game. You also write that you refuse to stake the banked skin. If a duel invite arrives in the last minute, the table already answered.

Suppose instead the panel shows no rate. You still fill cash, banked keepers, hours away, and the refused stake. The forecast cell stays as “not shown in UI.” That sentence is the result. You now know not to promise yourself a morning payout. You still deposited, which is the action that matters.

Developers have talked about a Global Market and Auctions. If those systems ever print a fee or a listing number, add a row then. Do not add the row now. A blank market row would be a rumour wearing a table.

When the worksheet is full, leave this page. Go to the bank guide for the walkthrough, the money guide for the session loop, and the code levels sibling so tomorrow’s grind still has a target. Tools are for writing. The vault is for depositing.
