Decorate the mechanism of the interests of Book A
The 15th rule: the starting point of any calculation
Contrary to popular ideas, your Book A does not work day-to-day. The bank freezes the meters according to a fortnightly calculation, cutting the calendar year into twenty-four separate periods to pay savings.
It's a binary mechanical and rigid The first fortnight runs from the 1st to the 15th, the second from the 16th to the end of the month.
Here's the trap. The money deposited only earns interest on the first day of the next fortnight. Conversely, any withdrawal cancels winnings from the first day of the current fortnight, sometimes erasing two weeks of patience.
The concrete impact of value dates on your earnings
This technical gap is called the « value date ». If you pay money on 2, that amount literally sleeps until 16 before enabling the calculation of interest livret a.
The sanction is identical in the other direction. Withdraw from funds on 14 retroactively remove all accrued interest Since the beginning of the month.
| Type of operation | Date of transaction | Value date (start/end of interest) | Impact on savers |
|---|---|---|---|
| Payment | 30 of the month | 1st of the following month | Gain of the entire fortnight |
| Payment | 2nd of the month | 16 of the month | Loss of 15 days interest |
| Withdrawal | 1st of the month | 31 of the previous month | Earnings of the previous 15 |
| Withdrawal | 14 of the month | 31 of the previous month | Loss of current fortnight |
These lost days seem anodized taken in isolation. Yet, put to an end, this mechanical neglect ends up snack a real part of your annual yield Without you noticing.
