SAVINGS ACCOUNTS FOR BOYS AND GIRLS

SAVINGS ACCOUNTS FOR BOYS AND GIRLS Interest on savings accounts is usually computed at from 2% to 4% annually, and is payable the first of each January and July. If not drawn when due, the interest or dividend, as it is sometimes called, is added to the deposit. For example: If John deposited $10 Jan. 1, his amount in the bank July 1 would be $10 plus the interest on $10 for 6 months at 4%, or $10.20. Since interest on savings accounts is not computed on parts of a dollar, the interest for the next 6 months would be computed on $10 only.

Interest on savings accounts is frequently calculated from the 1st and 15th of each month succeeding the several deposits. Thus, $10 deposited the 1st of any month would draw interest from date; but $10 deposited the 2d of any month would draw interest from the 15th, and money deposited on the 15th would draw interest from the 1st of the next month.

Thirty days are reckoned as a month.
