You can check it from Roblox’s My Transactions page on a web browser, then filter for purchases or currency purchases to see your Robux spending history. Roblox’s help page says to log into the account, click the Robux icon in the upper-right corner, and open My Transactions ; from there you can change the transaction type filter to view spending history.

Fast method

  1. Open Roblox in a web browser and sign in to the account you used for MM2.
  2. Click the Robux icon in the top-right.
  3. Open My Transactions.
  4. Set the filter to Purchases or Currency Purchases , depending on whether you want item spending or Robux top-ups.

Getting the total

Roblox’s transaction page is useful for seeing the entries, but users commonly total them manually by copying the transaction list into a spreadsheet and summing the amounts. Some guides also note that the page can show the date range and transaction summaries, which makes it easier to isolate MM2-related spending if you know the period you played most.

For MM2 only

If you mean only Robux spent in Murder Mystery 2 , you’ll usually need to filter your Roblox purchases for MM2-related items, game passes, or in-game purchases, then add those entries yourself. Roblox does not appear to provide a built-in “MM2 total spent” button; the best route is to review your full purchase history and calculate the total from the entries tied to MM2.

Simple example

If your history shows:

  • 49 Robux for an MM2 game pass.
  • 100 Robux for an MM2 item.
  • 25 Robux for another MM2 purchase.

Your total MM2 spend is 174 Robux.

TL;DR

Use Robux → My Transactions → Purchases/Currency Purchases in a browser, then total the MM2-related entries yourself.
