If you want to split one savings account into labeled sub accounts, the banks that actually offer the feature are almost all online: Ally Bank, SoFi, Chime, and Sallie Mae’s SmartyPig. Capital One 360 achieves a similar result a different way, by letting you open multiple separate savings accounts under one login. Most traditional banks, including Bank of America and PNC, offer goal-tracking tools rather than true sub accounts. The feature is free at every major provider, and your full balance earns the same interest rate no matter how you divide it.
What a Sub Account Actually Is
A sub account is a virtual label inside your savings account, not a separate account. The cabinet is one account; each divider marks off money for a specific purpose. Your bank sees one account with one balance. You see named segments like “Emergency Fund,” “Vacation,” and “New Car.” The money never actually leaves the main account. The bank just tracks how much you’ve assigned to each label.
Because sub accounts are internal bookkeeping rather than distinct accounts, they don’t come with their own routing or account numbers. You can’t set up direct deposit into a specific bucket or write a check against one. To spend the money, you move it back to the main balance first, then withdraw or transfer as usual. That extra step is part of the appeal. It creates just enough friction to keep you from raiding the vacation fund for takeout.
Online Banks That Offer Sub Accounts
The banks with the most developed sub account systems are digital-first. They built these tools into their apps from the start, so the experience tends to be smoother and more feature-rich than anything at a traditional bank.
Ally Bank Savings Buckets
Ally is probably the best-known name here. You can create up to 30 savings buckets within a single account, each with its own name, target amount, and target date.1Ally Financial. What Are Ally Bank’s Savings Buckets and Boosters? Ally also offers Boosters, which include recurring transfers and round-up features that automatically funnel money into a chosen bucket. The account earns a competitive high-yield APY on the full combined balance.
SoFi Vaults
SoFi’s checking and savings product includes Vaults, which work like Ally’s buckets. Name each vault, set a goal, and watch the progress. SoFi members with eligible direct deposit can earn a higher APY on savings balances including vaults. Without qualifying direct deposit the rate drops significantly, so this account works best if you route your paycheck through SoFi.
Chime Savings Goals
Chime takes a similar approach with Savings Goals, letting you separate money into labeled categories inside one savings account. Chime also offers automatic round-ups on debit card purchases, depositing the spare change into savings.
SmartyPig by Sallie Mae
SmartyPig is built specifically around goal-based saving. You create individual savings goals, each with a target amount and timeline, and the account tracks your progress. It currently offers one of the higher APYs among accounts with built-in goal features. It’s a good fit if the goal-tracking interface matters to you more than a full banking relationship.
Capital One’s Multiple-Account Approach
Capital One 360 doesn’t offer virtual sub accounts. Instead, it lets you open multiple separate 360 Performance Savings accounts under a single login. Each has its own balance, its own account number, and its own nickname. You manage them all from one dashboard, which gives you a similar organizational view. Because they’re technically distinct accounts, each one can receive direct deposits or external transfers independently, which no true bucket system supports.
The tradeoff is administrative overhead. Each account is a real account on your records, and closing one you no longer need takes more steps than deleting a virtual bucket. If you want true separation, where money in one goal can’t accidentally get swept into another, this structure delivers that.
What Traditional Banks Offer Instead
Most large brick-and-mortar banks don’t offer true sub accounts. What they offer instead are goal-tracking overlays: digital tools that let you set savings targets and visualize progress, but without partitioning your money.
Bank of America’s Life Plan is a good example. More than 10 million clients have used it to set and track financial goals through the mobile app, and the bank reports users have added over $55 billion to their accounts since the feature launched.2Bank of America. Over 10 Million BofA Clients Use Life Plan to Pursue Financial Goals Through Personalized Digital Experience Life Plan helps you identify priorities and set up steps, but it doesn’t carve your savings balance into isolated segments. Your money sits in one undivided pool. The app just shows you a progress bar.
PNC Bank’s Virtual Wallet takes a more structural approach by bundling three separate accounts, Spend, Reserve, and Growth, under one product. This gives you real separation between everyday spending money and longer-term savings. The system is fixed at three categories rather than letting you create custom goals, so if you want more flexibility, a dedicated online bank’s bucket system will serve you better.
How Interest Works Across Buckets
Because sub accounts are divisions of a single savings account, the whole balance earns interest at the same annual percentage yield. If your account pays 3.30% APY and you have $5,000 split across four buckets, interest is calculated on the full $5,000, not separately on each bucket’s share. Interest gets credited to the main account balance, and most banks don’t break out how much interest each individual bucket “earned.”
This is actually an advantage over holding multiple separate savings accounts at different banks, where each smaller balance earns interest independently. A single larger balance in one account with sub accounts produces the same total interest without the hassle of tracking yields across institutions.
FDIC Coverage Doesn’t Multiply
Sub accounts do not increase your FDIC coverage. The FDIC insures $250,000 per depositor, per insured bank, for each ownership category.3FDIC.gov. Understanding Deposit Insurance Since buckets are internal labels within one savings account, the FDIC treats them as a single combined balance. If you have $200,000 spread across ten buckets at one bank, you have $200,000 in FDIC-insured savings, not ten separately insured pots.
Ownership categories that do qualify for separate coverage include single accounts, joint accounts, certain retirement accounts like IRAs, and trust accounts.4Federal Deposit Insurance Corporation (FDIC). Your Insured Deposits If your total savings at a single bank approach $250,000, opening a joint account or an account at a second FDIC-insured bank adds coverage. Adding more buckets within the same account does not.
Sub Accounts Don’t Shield Money From Your Own Bank
Labeling $3,000 as “Emergency Fund” feels like putting it in a safe, but your bank doesn’t see it that way. If your checking account at the same bank goes negative, the bank can pull money from your savings, including from any bucket or vault, to cover the shortfall. This is called the right of offset, and it’s built into the account agreements you signed.
Many banks also offer overdraft sweep arrangements where savings is automatically tapped to cover checking overdrafts. A sweep can drain a bucket you were carefully building without any additional authorization beyond the original agreement. If overdraft protection matters to you, read the sweep terms carefully. Labeled buckets offer zero legal protection against these transfers.
Withdrawal Limits to Watch For
The federal government eliminated the old six-withdrawal-per-month limit on savings accounts in April 2020, and as of 2026 there are no plans to reinstate it. Many banks still enforce their own internal limit, often six electronic transfers per month, as a matter of bank policy rather than federal law.
Banks that maintain the limit typically count online transfers, mobile transfers, and automatic sweeps toward the cap. ATM withdrawals and in-person transactions usually don’t count. Exceeding the limit can trigger fees in the range of $5 to $15 per extra transaction, depending on the bank. Before choosing a bank for sub accounts, check whether the institution still enforces a monthly transfer cap, because moving money between buckets and your checking account can eat through that limit quickly.
How to Set Them Up
The setup is nearly identical across every bank that offers the feature. Open the mobile app, navigate to your savings account, and look for an option labeled Buckets, Vaults, Goals, or something similar. Tap to create a new one, give it a name, and optionally set a target dollar amount and target date. The app will calculate how much you need to save per week or month to hit that goal on time.
Fund the new sub account with an instant internal transfer from your main balance. From there, set up recurring automatic transfers: a fixed weekly amount from checking, a percentage of each direct deposit, or round-ups on debit card purchases, depending on what the bank supports.
When you reach a goal or decide to repurpose the money, close the bucket and the funds flow back to your main savings balance instantly. You can rename buckets, adjust targets, or delete them at any time. Unlike a CD or a separate account, there’s no penalty, no waiting period, and no paperwork to reorganize.
