Why does my checking/savings account offer a higher interest rate than a standalone savings account?
The key is that you need to use your debit card to earn the higher interest rate. The bank can offer a higher interest rate on accounts connected with a debit card because: They earn additional income through debit card fees charged towards account holders, among other things. They offer the higher interest rate specifically to encourage people to use their debit cards. By offering a joint checking/savings account that requires you to use your debit card, the bank is assuming that you'll keep more money in your account than you would in a standard checking-only account. Your higher balance translates into more money the bank can loan out or invest, which usually leads to higher profit for them. Businesses pay fees to the bank to accept debit cards. These fees represent another source of profit for the bank. The more you use your debit card, the more the bank earns in fees, so the bank encourages you to use your debit card more frequently through incentives like a higher interest rate or waiving fees on your account if you use your card enough. Plus, since it's likely that an individual who maintains a fairly high balance in an account linked to a debit card is going to spend more (simply because they can spend more), banks will sometimes waive fees on the consumer side for balances over a certain amount.
