Yes – you can get savings accounts with sub-accounts which also earn interest.  If there is a minimum deposit requirement to earn bonus interest, the amount you deposit into each of your sub-accounts is considered as a lump sum together.  For example, if you’re required to deposit $1,000 minimum monthly to earn bonus interest, you could put $600 into your car fund, $200 into your holiday fund and $200 into your Christmas present fund, and you’ll be credited with depositing $1,000 altogether, even though it’s divided up into separate sub-accounts.
