What it means
The idea is simple: day-to-day spending happens in one account, while spare money sits in the savings account earning a higher rate. The link lets the bank move money from one to the other, either when you ask or automatically under rules you agree in advance.
The most common use is overdraft protection. If a payment would take the current account below zero, the bank pulls the shortfall from the linked savings account instead of rejecting the payment or charging overdraft interest.
Many banks charge a small fee for each automatic transfer, which is usually lower than a bounced payment or an overdraft charge. Linked accounts can also make it easier to save.
Some customers set up a standing instruction that moves a fixed sum, or rounds up each card purchase to the nearest whole dollar and sends the difference, into savings. Because the money leaves the current account automatically, it is less tempting to spend.
Businesses use the same idea on a larger scale. A company may link a deposit account to its operating account so that cash above a target balance is moved to earn interest and cash is drawn back when the balance falls too low.
Small firms often do this by hand each week, while larger ones use automatic sweeps. There are limits to watch.
Some savings accounts cap the number of withdrawals or transfers per month and charge a fee when the cap is exceeded, and a linked account does not change how deposit insurance works, since both accounts are usually counted together for the same depositor at the same bank. It is also worth checking whether the bank notifies you when a transfer happens, so you can spot a pattern of regular shortfalls.
In practice
Real-world examples.
Example
A freelance designer links her savings account to her current account. When a client pays late and a $900 bill comes due, the bank automatically covers the gap from savings and she pays only a small transfer fee. She then tops the savings account up when the client's payment arrives, so the protection is ready for the next gap.
Example
A young couple sets up a rule that moves $200 into their linked savings account on the day each salary arrives. Over a year they build up $4,800 without having to remember to transfer money. Because the transfer happens before they see the money in their spending account, they barely notice it is gone.
Example
A small bakery links a business deposit account to its operating account. At the end of each week, the owner moves cash above $15,000 into the deposit account, and moves it back before payroll. The routine earns a small amount of extra interest on money that would otherwise sit idle for days at a time.
Formula
Calculation
Transfer needed for overdraft protection = payment amount - current account balance.
Suppose a current account holds $300 and a rent payment of $1,000 is due. The shortfall is 1,000 - 300 = $700. The bank moves $700 from the linked savings account, leaving the current account at $0 after the payment. If the bank charges a $10 transfer fee, the total cost is $10, compared with an overdraft fee that might be $35, so the linked account saves 35 - 10 = $25.Case study
Seen in the real world.
Willowbrook Studio is an illustrative, fictional design firm with erratic cash flow. Its owner kept all her money in one current account and paid overdraft charges four or five times a year when client payments arrived late.
On her accountant's advice she opened a savings account, linked it to the current account and moved a buffer of $5,000 into it. The next time a large supplier invoice landed before a client payment, the bank covered the $1,800 shortfall from savings, and the payment went through without an overdraft fee.
Over the year, in this illustrative case, the firm paid two small transfer fees instead of five overdraft charges, and the buffer earned interest in the meantime. The owner now treats the savings account as a standing safety net. She also set a calendar reminder to refill it whenever it falls below $3,000, so that the cover is always available.
Watch out
Common mistakes.
- Assuming the link is free, when many banks charge a fee for each automatic transfer from savings to cover an overdraft, and the fee can add up if shortfalls are frequent.
- Letting the savings balance run down and forgetting to refill it, so that the protection fails when it is needed.
- Forgetting that transfer limits on some savings accounts can lead to fees or restrictions when the link is used often.
Questions
People also ask.
Can I link accounts at different banks?
Often yes for transfers, though automatic overdraft cover generally works only between accounts at the same bank.
Does linking change my interest rate?
No, each account keeps its own rate, although some banks pay a bonus rate or waive monthly fees when you hold both accounts and keep a minimum balance in them.
Is a linked savings account the same as a sweep account?
Not exactly; a sweep account moves money automatically according to set balance targets, while a linked account may move money only when needed or when you instruct it.
