Interest payments happen on a schedule set by your bank, usually monthly or daily

Your bank decides when to pay interest on your savings account, and the timing depends on the bank's own policy. Most banks compound and credit interest monthly — meaning they calculate what you've earned and add it to your account once a month, usually on the same day each month. Some banks compound daily but still credit (actually deposit) the interest only once a month. A smaller number of banks credit interest quarterly (four times a year) or even annually, though this is less common now.

The date your interest posts matters because once it's in your account, it becomes part of your balance and starts earning interest itself. If your bank compounds daily but credits monthly, you're earning interest on your interest every single day, but you won't see that money appear in your account until the monthly posting date arrives.

Key Takeaways

  • Most banks credit interest monthly, though some do it quarterly or annually — check your account agreement or ask your bank directly.
  • Compounding (how often interest is calculated) and crediting (when it actually appears in your account) are two different things.
  • Daily compounding with monthly crediting means your money earns more than monthly compounding, even though you see the deposit only once a month.
  • The interest rate your bank offers matters more than the posting schedule, but knowing when interest posts helps you track your balance.

The difference between compounding and crediting

Compounding is how often your bank calculates the interest you've earned. Crediting is when that interest actually appears in your account. These two things don't have to happen on the same schedule, and understanding the difference means you'll know how much your money is really growing.

If a bank compounds daily, it's calculating your interest every single day based on your balance that day. That daily interest then earns interest of its own the next day. Over a month, this adds up to more money than if the bank only calculated interest once at the end of the month. But if the bank only credits that interest once a month, you won't see it in your account until that monthly posting date — even though it's been working for you all along.

A bank might also compound monthly and credit monthly, which is simpler but means your interest earns less because it's only being recalculated once a month instead of every day.

Where to find your bank's interest schedule

Your bank's posting schedule is in your account agreement or disclosure statement — the document you received when you opened the account, or that you can request anytime. Look for language like "interest is credited on the last business day of each month" or "interest compounds daily and is credited monthly." If you can't find it in that document, call your bank's customer service line or log into your online account and look for a section labeled "Account Details" or "Interest Information."

Online banks and credit unions often post this information on their website under "Savings Account Terms" or "Rate Information." Some banks also show you in real time how much interest you've earned so far in the current month, even before it posts to your account.

Why the posting date affects your balance

The day interest posts is the day it becomes part of your official account balance. This matters if you're tracking your money carefully or if you're close to a minimum balance requirement. Some savings accounts require you to keep a certain amount in the account at all times — if your balance drops below that, you might lose the interest rate or pay a fee. Knowing when interest posts means you know when your balance will go up and whether you'll stay above any minimum.

It also matters if you're planning to withdraw money. If you withdraw the day before interest posts, you won't earn that month's interest. If you withdraw the day after, you will. Banks calculate interest based on your balance on specific dates, so timing can make a small difference over time.

How interest rates and posting schedules work together

The interest rate your bank offers is more important than how often it posts. A bank offering 4.5% interest compounded daily will give you more money than a bank offering 2% interest compounded daily, no matter what the posting schedule is. But between two banks offering the same rate, the one with daily compounding will give you slightly more than the one with monthly compounding.

When you're comparing savings accounts, look at the Annual Percentage Yield (APY) — this is the rate that already includes the effect of compounding, so you can compare accounts directly without doing math yourself. The APY tells you what you'll actually earn in a year, taking the compounding schedule into account.

What happens if your bank changes the posting schedule

Banks can change how often they credit interest, though they must notify you before the change takes effect. You'll receive notice in writing or electronically, usually 30 days before the change happens. If your bank switches from monthly to quarterly crediting, for example, you'll earn the same amount of interest over a year, but you'll see it in your account less often.

If you're unhappy with a change, you have the right to close the account and move your money to another bank. Some banks offer better posting schedules than others, and if frequent interest deposits matter to you, it's worth shopping around.

Frequently Asked Questions

Can I withdraw my interest before it posts to my account?

No. Interest that hasn't been credited yet isn't in your account, so you can't withdraw it. Once it posts, it becomes part of your balance and you can withdraw it like any other money. Some banks show you "pending interest" in your account details, but that's just informational until the posting date arrives.

Do all banks post interest on the same day?

No. Each bank sets its own posting schedule. One bank might post on the last day of the month, another on the 15th, another on the first business day of the next month. Check your account agreement to know your specific bank's schedule.

If I move money between accounts, does it affect when interest posts?

No. Transfers between your own accounts don't change your bank's interest posting schedule. The interest will still post on whatever day your bank has set. However, moving money out of the savings account before interest posts means that money won't earn interest for that period.

Why do some banks compound daily but credit monthly instead of daily?

Daily crediting would mean your bank has to process thousands of tiny deposits every single day, which costs them money. Monthly crediting is cheaper for them to manage. Daily compounding with monthly crediting is a compromise — you get the benefit of daily compounding without the bank's processing costs.

Does the posting date change if I have multiple savings accounts?

Usually no. Most banks use the same posting date for all savings accounts of the same type at that bank. But some banks let you choose, or they may have different schedules for different account types. Ask your bank if you're not sure.
