Yes, some savings accounts pay interest monthly, but most pay daily and compound it monthly
Many savings accounts do credit interest to your account every month. The difference between monthly crediting and daily compounding matters less than you might think — what matters is the annual percentage yield (APY), which already accounts for how often interest compounds.
Banks that advertise monthly interest crediting are usually online banks or credit unions. They calculate interest daily based on your balance, then deposit the total into your account on a set day each month — often the first or the last business day. A few traditional banks still do this, but most have moved to daily compounding with monthly or quarterly crediting, which produces a slightly higher return.
The real question is not when interest hits your account, but what rate you are getting. A savings account that compounds daily at 4.50% APY will earn you more money than one that compounds monthly at 4.25% APY, even though the second one credits your account more often.
Key Takeaways
- Monthly interest crediting means the bank deposits earned interest into your account once a month, usually on the first or last business day.
- Daily compounding with monthly crediting is more common now and produces slightly higher returns than true monthly compounding, because interest earns interest more often.
- The APY listed on the account already reflects how often interest compounds, so you can compare rates directly without doing extra math.
- Online banks and credit unions are more likely to offer monthly crediting than traditional brick-and-mortar banks.
- The interest rate itself matters far more than the crediting schedule — a higher rate with less frequent crediting usually beats a lower rate with more frequent crediting.
How monthly interest crediting actually works
When a bank says it pays interest monthly, it means the interest calculation runs every day, but the deposit into your account happens once a month. On the crediting date — say, the last business day of the month — the bank adds up all the daily interest earned and deposits it as a lump sum.
This is different from daily compounding, where interest earned on one day when ready starts earning interest on the next day. With monthly crediting, you lose a few days of compounding at the end of the month. The difference is small — usually a few cents per thousand dollars — but it is measurable over a year.
Some banks let you choose when the crediting date falls, though this is rare. Most set it automatically. A few credit interest on the 15th and the last day of the month, splitting the year into two halves.
Why the APY is what actually matters
The annual percentage yield is the rate you see advertised, and it already includes the effect of how often interest compounds. A bank cannot advertise a 4.50% APY with monthly compounding and a 4.50% APY with daily compounding — the daily one would be slightly higher because of the extra compounding.
This means you can compare APYs directly without worrying about the compounding schedule. If Bank A offers 4.50% APY with monthly crediting and Bank B offers 4.48% APY with daily compounding, Bank A is paying more, period. The math is already done.
The catch: APY is only may provide if you leave the money untouched for a full year. If you withdraw money mid-month, the interest calculation may change depending on the bank's rules. Some banks use the average daily balance method, others use the low balance method. Read the account terms to see which one applies.
Where to find accounts with monthly interest crediting
Online banks are the most reliable source. Marcus by Goldman Sachs, Ally Bank, American Express Personal Savings, and Discover Bank all credit interest monthly. Credit unions often do as well — check with yours by looking at the account disclosure document or calling.
Traditional banks with physical branches rarely advertise monthly crediting anymore. They usually compound daily and credit quarterly or monthly without making a point of it. If monthly crediting matters to you for tracking purposes, call the bank and ask when interest hits your account.
High-yield savings accounts almost always credit monthly, because they are offered by online banks. Money market accounts vary — some credit monthly, others quarterly. The account agreement will say.
The difference between monthly crediting and daily compounding
| Feature | Monthly Crediting | Daily Compounding |
|---|---|---|
| Interest calculated | Daily, but deposited once a month | Daily, and compounds when ready |
| When you see it in your account | Lump sum on a set date each month | Spread across the month as it accrues |
| Interest earning interest | Starts the day after crediting | Starts the next day after it accrues |
| Annual return at same rate | Slightly lower due to less compounding | Slightly higher due to more compounding |
| Typical APY difference | Usually reflected in the advertised rate | Usually reflected in the advertised rate |
The table shows the mechanics, but remember: the APY you see already accounts for these differences. You do not need to calculate anything yourself.
What to check before opening an account for monthly interest
If you want to see interest hit your account monthly for budgeting or tracking reasons, confirm the crediting date before opening. Some banks credit on the first business day of the month, others on the last. A few let you choose.
Check whether the account has a minimum balance requirement. Some high-yield savings accounts require $0 to open but pay the advertised rate only if you maintain a certain balance — often $25,000 or more. Below that, the rate drops. The account disclosure will spell this out.
Verify the interest rate is not promotional. Many online banks offer a high rate for the first few months, then drop it. The disclosure document will say how long the rate lasts and what the standard rate is after that.
Frequently Asked Questions
Does monthly interest crediting mean I earn more money?
No. The APY already reflects how often interest compounds. A 4.50% APY is a 4.50% APY whether it compounds daily or monthly. The bank has already done the math and adjusted the advertised rate accordingly.
Can I withdraw money right before the monthly crediting date to avoid losing interest?
No. Interest is calculated based on your balance each day, not on when you withdraw. If you have $10,000 in the account for 20 days and withdraw it before the crediting date, you earn interest only on those 20 days. The crediting date does not change what you have earned.
What happens to my interest if I close the account before the crediting date?
You keep the interest you have earned up to that point. Most banks credit accrued interest when you close, even if the regular crediting date has not arrived yet. Confirm this with the bank before closing.
Is there a difference between a savings account that credits monthly and a money market account that credits monthly?
The crediting schedule is the same, but money market accounts usually offer higher rates and may require a larger minimum balance. They may also limit how many withdrawals you can make per month. Check the account terms for both.
If I move money between accounts at the same bank, does it affect when interest credits?
No. Interest is calculated on your balance in each account separately. Moving money between accounts does not change the crediting date or the amount of interest earned, only which account holds it.
