A credit card purchase is an expense; paying that debt later from your bank account is not a second purchase. To track it without double counting, record purchases as card expenses and the repayment as a transfer from the source account. Record any interest and fees separately too. This lets you check both your spending and your remaining debt without confusing your bank balance with how much you can afford to spend.

Purchases, debt and card bills are different things
A debit card uses money from the linked account, usually with an immediate charge. A credit card lets you use financing that you must repay under the agreed terms. Banco de España distinguishes these arrangements: the same recording approach should not be applied to both.
With a credit card, a purchase creates an expense and increases the amount you owe. The subsequent card bill settles all or part of that debt. The payment date and method depend on the contract and statement; not every card collects payment on the last day of the month, and not every form of deferred payment has the same cost.
How to represent the transactions in Finantzak
Finantzak distinguishes income, expenses and transfers, and lets you represent credit cards alongside other accounts. On Android you can keep personal records locally for free; web access and personal synchronisation require Premium. For this task, identify the bank account and card separately and start with opening balances you can verify.
Record each purchase as an expense on the card, with its date and category. If the bank charges interest or fees, record them separately as expenses on that card. Represent the debt repayment as a transfer from the bank account to the card, not as another purchase expense. Recording that transfer in Finantzak does not instruct the bank to make a payment.
This procedure explains the recording principle, not a sequence of buttons shared by every version. The new dedicated card payment and instalment plan forms described in the product reference are part of a local Android revision awaiting publication; they are not a requirement and are not presented here as publicly available to everyone.
Fictional example: an 80 EUR purchase and a 2 EUR charge
Suppose a bank account holds 1,000 EUR and a card has no opening debt. In the same period you make an 80 EUR purchase and the bank applies a hypothetical 2 EUR fee, recorded on the card. You then repay the full 82 EUR from the bank account. There are no other transactions, accounts or pending charges in this example.
Total spending is 80 + 2 = 82 EUR. Before repayment, the bank still shows 1,000 EUR, but you owe 82 EUR: the simplified combined position is 1,000 − 82 = 918 EUR. After repayment, the bank holds 918 EUR and the debt is zero. The payment changes where the amount appears; it does not add another 82 EUR expense.
The 918 EUR is not a spending recommendation or a cash flow forecast: the example excludes other commitments. The 2 EUR fee is invented to explain the recording process; it is not a Finantzak fee or a bank's actual tariff.
Fictional example: changes in the account and card
| Stage | Bank balance | Card debt | Total expenses |
|---|---|---|---|
| Start | 1,000 EUR | 0 EUR | 0 EUR |
| After the 80 EUR purchase | 1,000 EUR | 80 EUR | 80 EUR |
| After the 2 EUR fee | 1,000 EUR | 82 EUR | 82 EUR |
| After the 82 EUR repayment | 918 EUR | 0 EUR | 82 EUR |
How to check that you have not counted the card bill twice
Review the transaction details for both the account and the card. The example should show an 80 EUR purchase, a 2 EUR fee and an 82 EUR transfer between the two accounts. When considering both accounts, expenses should total 82 EUR, not 164 EUR. The 82 EUR leaving the bank account reduces the debt rather than repeating the purchase category.
If you import statements, compare the card bill debit in the bank account with the credit on the card and any transfer you have already recorded. Do not assume that matching descriptions automatically link entries. Keep a single representation of the repayment and check dates and amounts before correcting duplicates; do not delete genuine purchases to make a total match.
Also compare the recorded debt with the statement using the same cut-off date. A purchase after the statement closes or a pending authorisation may explain differences. Finantzak calculates from recorded transactions: it does not automatically know about missing bank transactions.
What changes with a partial payment or a different month
If the payment is partial, the transfer reduces the debt by the amount paid; the rest remains outstanding. Do not calculate the principal repaid by simply subtracting an instalment that may include interest without checking the bank's breakdown. As Banco de España explains, new purchases, interest and fees can increase revolving debt despite regular payments.
If you buy in one month and pay in another, retain the date of each event: the expense on the purchase date and the transfer on the payment date. The month of the card bill can have money leaving the bank without an equivalent new purchase. This is why the difference between income and expenses for a period is not the same as the available bank balance.

Put it into practice
- Check the opening balances of the bank account and credit card.
- Separate purchases, interest or fees, and repayment transfers.
- Compare expenses and debt with the statement at the same cut-off date.
- Review an imported card bill before adding a repayment that is already recorded.
