Estimate interest on a French Livret A account using a rate you enter. Choose a simple constant-balance model or eligible half-month periods between a deposit and withdrawal.
Simple estimate = balance × annual rate × months / 12. Half-month estimate = balance × annual rate × eligible periods / 24.
At an assumed annual rate of 2%, a €1,000 constant balance for 12 months earns €20. This is an illustrative rate and is not presented as the current Livret A rate.
The dated model covers one deposit and one withdrawal in the same calendar year and assumes a constant rate. Real accounts can have rate changes, multiple transactions and annual interest capitalization. Livret A is a French regulated product, not a generic savings account.
