Did you incur an interest/finance charge in your credit card account?
Do the charges seem to be much higher than you expected?
Well, maybe it’s because you were thinking of a different way of computing for the interest! In an ordinary case, interest is computed as:
Interest = Principal x Rate of Interest
So if the amount borrowed is P10,000 and the interest rate is 3.5%, the interest should be:
Principal = 10,000
Rate = 3.5%
Interest = P10,000 x 0.035 = P350
If your amount due last month in your credit card account was P20,000 and you paid a total of P10,000 on or before the due date, do you think you will be charged interest on the P10,000 and thus expect the interest to be P350 in the next bill?
The answer is a big NO! Interest charges in a credit card account do not work that way. You will be charged interest not in the P10,000 balance but in the average daily balance of all the purchases you made during that month and in the purchases that you make in the next (or succeeding) billing cycle.
To illustrate the point above, refer to the interest charges computation (provided to me by my credit card provider which I requested for me to be fully aware of how I am being charged interest in my account) given to below:

Notes:
- My previous billing cycle started 1/17 and ended Feb 18.
- Amount due me was P61,154.23
- I paid a total of P60,000 on the due date of March 12.
- My unpaid balance was only P1,154.23.
- I used my card just four times from Feb 19 to March 18, the first of which was on February 22, and the total amount purchased was P672.41 + 650.50 + 2331.03 + 498.36 + 581 = P4,733.29.
- Balance from previous bill plus new charges = P1,154.23 + P4,733.29 = P5,887.52 only.
Credit card companies use weighted average in computing for the Average Daily Balance (ADB) of your account. How is it done? Let me try my best to explain it to you.
- From my first purchase (Jan 17) to my next purchase (Jan 27), there are 10 days. That is why in the number of days column, you see an entry of 10.
- Daily balance for my Jan 17 purchase is computed by multiplying the entries in Columns (A) and (B). P1071.75 x 10 = P10717.50
- Perform steps (a) and (b) to all rows in the table and you will get the Number of Days and Daily Balance values. This applies not only for purchases but also for payments made.
- Notice the 2 blank cells in the Debit column dated Feb 18 and Feb 19. Remember my previous cut-off date was Feb 18, right? So treat Feb 19 as if I made a purchase (even though I have not), so from Feb 18 to Feb 19 that is one day (that is why the entry in the Number of Days is 1). And then from Feb 19 to Feb 22 (my first purchase in the next cycle) that’s 3 days.
- To solve the ADB, get the SUM of the entries in the Number of Days column (let us call it TOTAL), then get the SUM of the entries on the Daily Balance column (let us call this DAYS). Divide TOTAL by DAYS. The result is your ADB.
To compute for the interest, use the formula below:
Interest = ADB x Interest Rate x 12 (months) x DAYS / 365
= 36209.14 x 3.5% x 12 x 60 / 365
= P2, 499.92
Therefore the interest I had to pay was P2,499.92 — for failing to pay P1,154.23 of the P61,154.23 bill that was due me.
If we’d compute the interest rate using the ADB as basis, it would be:
(2499.92/36209.14) x 100% = 6.9041131% or almost 7%. That’s 3.5% interest for 2 months.
I was lucky enough to have my request of reversal of the interest charge approved. It pays to be a client with a good credit record. I have been paying my bills in full and so asking for a reversal of the interest charges was not a big issue. Otherwise this would have been one of the worst things that I have done — getting charged P2499.92 in interest just because I failed to pay the P1,154.23 balance on time.
Would you still care not to pay your credit card bill in full on or before the due date? Your answer is as good as mine!
Have a nice day!
