Help with credit card balance calculations

Post by JerryV »

Hello! I am new to MMEX and just entered a bunch of transactions on a credit card account, including a refund and a payment. The refund was put in as a deposit and the payment was a transfer from another account in the system. Both show up in the 'Deposit' column but are not offsetting the balance of all the withdrawal transactions (each card transaction) on the credit card account. They seem to just continue to increase the balance of the account, rather than bringing it down as expected. I notice that deposits and withdrawals seem to calculate correctly on a bank account (deposits add and withdrawals subtract), so I would have assumed it worked the same way with a credit card account.

Can anyone think of something I'm doing wrong? Thanks in advance for the help!

Credit card are inverse on bank accounts.

Thanks for your reply @MlinMMEX. Here is the build info.

I think I understand that credit cards would be the inverse of a bank account, but I wouldn't have expected BOTH deposits and withdrawals (credits and debits) to add to the overall account balance. That seems like either a bug or something I'm doing wrong.

My apologies for the false alarm... I went back through line by line to try and figure out what I had done wrong, and the advice about credit cards being the inverse of a bank account ended up being the key. I had put in a starting balance, but put it in as a credit balance (positive number) instead of an amount owed (negative number) and then misunderstood what I was seeing on the running balance in the register. Once I fixed the starting balance, everything on the running balance started to make sense again. Thanks all!
