High yield savings accounts (HYSA) offer competitive interest rates compared to traditional savings accounts. This calculator helps you estimate potential earnings from a HYSA by accounting for compound interest and different compounding periods.
How High Yield Savings Accounts Work
A high yield savings account is a type of deposit account that offers higher interest rates than traditional savings accounts. These accounts are typically offered by online banks and credit unions, and they're insured by the FDIC up to $250,000 per depositor.
Key Features
- Higher interest rates than traditional savings accounts
- FDIC insurance protection
- Easy access to funds (usually with no monthly maintenance fees)
- Online management through the bank's website or mobile app
How Interest is Calculated
The interest on a high yield savings account is typically calculated using simple interest, where the interest is calculated on the original principal amount only. However, some accounts may offer compound interest, where interest is calculated on both the original principal and the accumulated interest.
Important Note
Interest rates on high yield savings accounts can change frequently, especially during economic downturns. It's important to monitor your account regularly and consider transferring funds to a CD or other investment vehicle if you need access to your money.
Formula and Assumptions
The interest calculator uses the following formula for simple interest:
Simple Interest Formula
Interest = Principal × (Rate ÷ 100) × Time
Total Amount = Principal + Interest
For compound interest, the formula is:
Compound Interest Formula
Total Amount = Principal × (1 + Rate ÷ (100 × Compounding Periods per Year))^(Rate × Time)
Assumptions
- Interest rates are annual percentages
- Time is measured in years
- No additional deposits or withdrawals during the period
- Interest is compounded annually unless specified otherwise

Here's a comparison of different savings options to help you decide which is right for you:
| Account Type | Interest Rate | Access to Funds | Minimum Balance | Fees |
|---|---|---|---|---|
| High Yield Savings Account | 1.00% - 5.00% APY | Instant | $0 - $10,000 | None |
| Traditional Savings Account | 0.01% - 0.50% APY | Instant | $0 - $10,000 | None |
| Money Market Account | 1.00% - 3.00% APY | Instant | $1,000 - $10,000 | $10 - $50/month |
| Certificate of Deposit (CD) | 1.50% - 5.00% APY | After maturity | $1,000 - $100,000 | Early withdrawal penalty |
Frequently Asked Questions
What is the difference between APY and APR?
APY (Annual Percentage Yield) is the real rate of return earned on an account, taking into account the effect of compounding interest. APR (Annual Percentage Rate) is the stated interest rate before compounding is taken into account.
Are high yield savings accounts FDIC insured?
Yes, high yield savings accounts are typically FDIC insured up to $250,000 per depositor, just like traditional savings accounts.
How often is interest calculated on a high yield savings account?
Interest is typically calculated daily and credited to the account monthly. Some accounts may offer compound interest, where interest is calculated on both the original principal and the accumulated interest.
What happens if I withdraw money from a high yield savings account?
Withdrawing money from a high yield savings account typically does not incur any fees, but you may lose some of the interest earned if you withdraw before the end of the interest period.
