SoFi pays interest daily and deposits it monthly

SoFi calculates interest on your savings account balance every single day, but you only see the money hit your account once a month. The daily calculation means your interest rate applies to whatever you have saved on that day — so if you deposit $5,000 on the 15th, interest starts accruing immediately on that $5,000. The monthly deposit is when SoFi actually moves the interest earnings into your account as real money you can spend or move elsewhere.

This setup is standard across most online banks. The daily calculation protects you because it means you earn interest on deposits the moment they land, rather than waiting until the end of a month to start earning. The monthly payout keeps the bank's accounting simpler and reduces the number of small transactions hitting your account.

Key Takeaways

  • SoFi calculates your interest every day based on your current balance, but deposits the earned interest into your account once per month.
  • The exact day of the month when interest posts can vary slightly depending on weekends and holidays, so check your account history to see your bank's pattern.
  • Interest starts accruing the same day you deposit money, so timing a deposit before month-end does not matter — you earn interest either way.
  • Your interest rate can change at any time, and SoFi will notify you before a rate change takes effect on your account.

When the monthly interest deposit actually appears

SoFi typically deposits interest on the last business day of each month, though the exact date can shift if that day falls on a weekend or holiday. You can see the deposit in your transaction history, labeled as "interest paid" or similar language. If you do not see interest posted by the third business day of the new month, log into your SoFi account and check your recent transactions — sometimes the deposit posts on the first business day of the following month instead.

The amount you receive depends on your current interest rate and your average daily balance for that month. If you had $10,000 in the account for the entire month and SoFi's rate is 4.50% annual percentage yield (APY), you would earn roughly $37.50 that month (before any rate changes). If you withdrew $5,000 halfway through the month, your interest would be lower because the calculation uses the balance you actually held each day.

How your balance affects the interest you earn

Every dollar you keep in your SoFi savings account earns interest at the stated APY. If you deposit $1,000 on the 1st and withdraw $500 on the 15th, SoFi counts $1,000 for 14 days and $500 for the remaining days of the month. The interest you earn that month reflects that exact pattern — you do not lose interest on the $500 you withdrew, but you do not earn interest on it for the days it was not in the account.

This is why moving money in and out frequently can slightly reduce your monthly interest earnings. If you keep money in the account longer, you earn more. There is no penalty for withdrawals, but the interest calculation is always based on the balance you actually held.

What happens if SoFi changes its interest rate

SoFi can change the interest rate on your savings account at any time. When a rate change happens, SoFi sends you a notice before the new rate takes effect — usually at least 30 days in advance. The new rate applies to interest earned starting on the effective date, so if your rate drops on the 15th of the month, you earn the old rate on the balance you held from the 1st to the 14th, and the new rate on the balance from the 15th onward.

You do not have to do anything when a rate changes. The new rate automatically applies to your account. If you want to move your money elsewhere because the rate dropped, you can withdraw your full balance and close the account with no penalty.

Interest rates and how they compare

SoFi's savings account interest rate changes based on the Federal Reserve's actions and market conditions. When the Fed raises rates, online banks typically raise their rates too — sometimes within days. When the Fed cuts rates, savings rates fall as well. SoFi's rate may be higher or lower than other online banks on any given day, so it is worth checking competitors if you are deciding where to open an account.

The rate SoFi advertises is the APY — the annual percentage yield. This is the actual return you will earn over a year if you leave the money untouched. It already accounts for the fact that interest compounds (you earn interest on your interest), so you do not need to do any math yourself. Just multiply your balance by the APY and divide by 12 to get a rough monthly earnings estimate.

Frequently Asked Questions

Can I withdraw my interest before the monthly deposit?

No. Interest is not available to withdraw until SoFi deposits it into your account at the end of the month. Once it is deposited, it becomes part of your balance and you can withdraw it anytime. There is no lock-in period or waiting time after the deposit posts.

Do I pay taxes on the interest SoFi pays me?

Yes. Interest earned on a savings account is taxable income. SoFi will send you a 1099-INT form in January if you earned $10 or more in interest during the previous year. You report this amount on your tax return. The interest is taxed as ordinary income at your regular tax rate.

What if I close my account mid-month?

You still receive the interest you earned for the days you held the account that month. SoFi calculates it based on your average daily balance through the day you close the account. The interest posts on the regular monthly schedule, even though your account is closed.

Does SoFi charge a fee to hold a savings account?

SoFi does not charge monthly maintenance fees or minimum balance fees on savings accounts. There are no hidden charges for deposits, withdrawals, or transfers. The only cost is the opportunity cost of earning a lower rate than you might elsewhere — but that is a rate decision, not a fee.

How do I know my interest rate is accurate?

Log into your SoFi account and look at your savings account details — the current APY is displayed there. You can also check your monthly statement or transaction history to see the exact interest amount deposited and work backward to verify the rate. If the amount seems wrong, contact SoFi customer service with your account number and the month in question.
