The first payment made into a savings deposit is smaller than it is for term deposits (at least 6 euros or 100 US dollars). You can also make extra payments during the entire deposit period, which will start earning interest as soon as they are received in the deposit account.
The first payment into a term deposit must be at least 190 euros or its equivalent in any other currency. You will define the deposit amount when you enter into the contract and you cannot change it during the term of the deposit.
Savings deposit is a reasonable choice if you wish to deposit a small amount every month. Opening a new term deposit every month does not always guarantee the best interest rate for you.
