What it means
The term is used loosely by banks and brokers rather than being a formally defined product. In practice it describes an arrangement where you register an outside account, often at a different institution, as an approved source or destination for transfers.
Setting it up usually means supplying the account number and routing details and then confirming ownership. The provider may send two tiny test deposits for you to check, or may use an online login to verify the account instantly.
Once approved, you can move money in either direction, usually in one to three business days, depending on the payment system used. Investors use this to fund brokerage accounts, move retirement contributions, or pull cash out after a sale.
Businesses use linked accounts to move money between entities, to fund payroll accounts from a main account, or to sweep surplus cash into a higher-interest account. Security is the main concern.
Because a link allows money to leave the account, providers add protections such as two-factor authentication, daily transfer limits and alerts when a new link is created. Account holders should review the list of linked accounts regularly and remove any they no longer use.
Fees and timing vary by provider and by country. Some transfers between accounts at the same institution are instant and free, while transfers to outside accounts may be slower and may carry a fee or a daily cap.
Before relying on a link for a time-sensitive payment, it is wise to run a small test transfer and confirm how long it takes.
In practice
Real-world examples.
Example
An investor links her bank account to a brokerage account and sets up a monthly transfer of $500. Each transfer funds a purchase of an index fund, and she checks the statement quarterly to make sure the transfers arrive. After a year she has invested $6,000 without ever logging in to move money by hand.
Example
A property manager links the company's rent collection account to a reserve account. Each Friday the system moves the balance above $20,000 into the reserve, which earns a higher rate. Before the monthly mortgage payments fall due, the manager moves enough cash back to cover them.
Example
A freelancer links her business account to her personal account and transfers a fixed owner's draw of $3,000 on the first of each month. The regular pattern makes her personal budgeting easier. It also gives her accountant a clean record of owner withdrawals, which helps when preparing the year-end accounts.
Formula
Calculation
Sweep amount = account balance - target balance.
Suppose a company wants its operating account to hold $10,000 and links a deposit account to receive any excess. At the end of the day the operating account holds $26,500. Sweep amount = 26,500 - 10,000 = $16,500, which is moved to the linked deposit account. If the deposit account pays 3% a year, the $16,500 earns 16,500 x 0.03 = $495 over a full year.Case study
Seen in the real world.
Meridian Trading is an illustrative, fictional import business that kept a large balance in a non-interest-bearing operating account because its owner worried about moving money between accounts. His accountant pointed out that tens of thousands of dollars were sitting idle most of the month.
The owner linked a higher-interest deposit account and set a rule that anything above $25,000 at the end of the day would be moved across. He also set a daily transfer limit and turned on alerts for any new linked account.
Over the following year, in this illustrative case, the idle cash earned a modest return, and the extra security settings meant that a phishing attempt aimed at adding a new link was blocked. He now reviews the list of linked accounts every quarter and keeps a short note of why each link exists. His accountant checks the same list when preparing the year-end accounts.
Watch out
Common mistakes.
- Linking an account and then forgetting about it, which leaves an open route for money to leave if the login is ever compromised.
- Expecting instant transfers, when many outside transfers take one to three business days to settle.
- Ignoring fees and limits, so that a large transfer is delayed or reduced by a daily cap.
Questions
People also ask.
Is the link the same as a joint account?
No, a linked account stays in your own name, while a joint account is owned by two or more people who each have rights over the money in it.
How long does it take to verify a link?
Instant verification takes minutes, while the test deposit method can take a few days.
Can I remove a link?
Yes, most providers allow you to delete a linked account from the online settings or by contacting customer support, and any scheduled transfers that depend on the link should be cancelled at the same time.
